A description of the procedures:
Welcome to the dream of life to the public information system.
Procedures based on JSP + JavaBean development, the database can use Access, MySql, MSSQL, Oracle database.
Development platform: Win2003 + + Apache2.0.52 Mod_jk Tomcat5.54 + 1.2.6 + JDK1.5
Normal procedures required for the operation of JVM (Java Virtual Machine) 1.5 or later.
Installation Instructions:
1, first of all, to build its own JSP server. Individual operation or integration with the Apache will do (I use the Apache Tomcat +) copy of the procedures to your server's root directory, I used Tomcat, the default path: Tomcat installation directory / webapps / directory. Make sure the directory called news system, if the system changes the directory name, the system comes with news picture will be displayed. If you are prepared to empty the data, you can change the directory you want, please according to practical situation.
</ Td> </ tr> </ table>
Second, database options:
1, if you choose Access database, open the WEB-INF \ classes \ DBConfig.property document, modify DBType value of 0 (ie DBType = 0; This is the default value), and amend the Access database path.
2, MySql database if they choose, to please themselves with MySql, and download MYSQL the JDBC driver to configure.
+ MYSQL good debugging JSP server.
Then enter the information system's directory.
In mysql prompt implementation: \. DreamNews_MySql.sql.
DBType revise the value of, and set your use of drivers.
3, if you select the SQL Server database, then you installed SQL Server (at the time of installation Please select mixed mode authentication),
Then download the SQL Server JDBC driver to configure.
Win2003 Server attention to the installation SQLServer2000 to install patches sp3.
+ Good JSP debugging SQL Server servers.
In the enforcement of sql query analyzer / SQL DreamNews_SQL.sql this angle this can be.
DBType revise the value of 2, and set your use of drivers.
4, if the use of the Oracle database, Members to resolve.
5, Note: Selecting a database must be set correctly corresponding database-driven procedure, if not, please do not change the system
The default value.
6, please do not change the program directory of news, otherwise the process may not be able to show that picture.
Because of the time, I only on the Windows platform under test Tomcat, Resin tested. Procedures to normal operation.
Integration with Apache and IIS software can also above normal operation. On the Linux operating under, please you to debug,
Please send any comments to fanwsp@126.com. I am not grateful. I am sure that the future will be tested in the Linux platform.
Because of personal effort and time, the information system will inevitably there are many shortcomings, welcome to all of you experts correction.

Log4j log management system using a simple note
Abstract: Log4j log management system using a simple note
</ Td> </ tr> <tr> <td height="35" valign="top" class="ArticleTeitle">
<table Width="673" border="0"> <tr> <td width="265"> </ td> <td width="398"> Log4j log management system using a simple note
Log4j has three main components: Loggers, and Layouts Appenders here can be understood as a simple log type, log output to the local and export log in what form. Integrated use of these three components can be easily record of the type and level of information, and to be running log export control pattern and location. Below the three separate components:
1, Loggers
Loggers components in this system are divided into five levels: DEBUG, INFO, WARN, and FATAL ERROR. This is a five-level order:
DEBUG <INFO <WARN <ERROR <FATAL
Understand that this is one very important point here Log4j have a rule: Loggers assumption that the level of P, if the Loggers had occurred in one of the high-level Q, P, it can activate, otherwise suppress.
</ Td> </ tr> </ table>
For example, Java programs:
/ / Build Logger an example, the name "com.foo"
Logger logger = Logger.getLogger ( "com.foo");
/ / Set the logger level. Procedures are usually not set the level logger. General settings in the configuration file.
Logger.setLevel (Level.INFO);
Logger barlogger = Logger.getLogger ( "com.foo.Bar");
/ / Below this request available, because WARN> = INFO
Logger.warn ( "Low fuel level.");
/ / Below this request can not be used because DEBUG <INFO
Logger.debug ( "Starting search for nearest gas station.");
/ / The name "com.foo.bar" examples barlogger will inherit an example "com.foo" level. Thus, the following this request available, because INFO> = INFO
Barlogger.info ( "Located nearest gas station.");
/ / Below this request can not be used because DEBUG <INFO
Barlogger.debug ( "Exiting gas station search");
Here "is available" means Logger can output information.
In the name of the Logger example, no restriction could be of interest from arbitrary name. Under normal circumstances recommendations to the location of the named Logger example, it is more effective in terms of the Logger naming. This makes each category to build their own log information, manageable. For example:
Static Logger logger = Logger.getLogger (ClientWithLog4j.class.getName ());
2, Appenders
Banned the use of log request only Log4j one of the small places, Log4j log system allows the log output to different places, such as the console (Console), paper (Files), according to the number of days or file size of a new document, to flow in the form sent to other places, and so on.
Its syntax is expressed as:
Org.apache.log4j.ConsoleAppender (console),
Org.apache.log4j.FileAppender (document),
Org.apache.log4j.DailyRollingFileAppender (produce a daily log file)
Org.apache.log4j.RollingFileAppender (file size, arrived at the designated size and it is a new document)
Org.apache.log4j.WriterAppender (log information to be sent to any format-designated place)
Configuration for use:
Log4j.appender.appenderName = fully.qualified.name.of.appender.class
Log4j.appender.appenderName.option1 = value1
…
Log4j.appender.appenderName.option = valueN
This log on to the output to provide a great convenience.
3, Layouts
Sometimes users want according to their own preferences formatted log output. Log4j can be in the back of additional Layouts Appenders to complete this function. Layouts offers four log output format, such as HTML styles according to specified forms, including log-level and the information contained logs and the style of the time, thread, patterns of the types of information and so on.
Its syntax is expressed as:
Org.apache.log4j.HTMLLayout (HTML table form layout),
Org.apache.log4j.PatternLayout (the flexibility to specify the layout mode),
Org.apache.log4j.SimpleLayout (including log information and the level of information string),
Org.apache.log4j.TTCCLayout (including log the time, thread, type information, etc.)
Configuration for use:
Log4j.appender.appenderName.layout = fully.qualified.name.of.layout.class
Log4j.appender.appenderName.layout.option1 = value1
…
Log4j.appender.appenderName.layout.option = valueN
The above is from the Log4j Principle shows the use of the Java programming in specific Log4j can refer to the use of the following examples:
1, the establishment of Logger examples:
Grammar: public static Logger getLogger (String name)
Actual use: static Logger logger = Logger.getLogger (ServerWithLog4j.class.getName ());
2, read configuration files:
Logger obtained examples, the following will be configured Log4j use of the environment:
Grammar said:
BasicConfigurator.configure (): Automatic use of default Log4j environment.
PropertyConfigurator.configure (String configFilename): Read the use of the characteristics of Java document prepared by the configuration files.
DOMConfigurator.configure (String filename): Read the form of XML configuration files.
Actual use: PropertyConfigurator.configure ( "ServerWithLog4j.properties");
3, insert the log information to complete the above steps, even after Below can log on at different levels should insert into your log records any place.
Grammar said:
Logger.debug (Object message);
Logger.info (Object message);
Logger.warn (Object message);
Logger.error (Object message);
Actual use: logger.info ( "ServerSocket before accept:" + server);
In the actual programming, to make Log4j really running on the system configuration files prior to the definition. Logger step is the definition, the difference between Appender and Layout use, as follows:
1, root Logger configuration, its syntax:
Log4j.rootLogger = [level], appenderName, appenderName,…
Logger level here that the priority, appenderName log information is output, multiple output can be designated to. Such as: log4j.rootLogger = INFO, A1, A2
2, configuration information log output destination, its syntax:
Log4j.appender.appenderName = fully.qualified.name.of.appender.class
Can be specified above a five destinations.
3, configuration information log format, syntax:
Log4j.appender.appenderName.layout = fully.qualified.name.of.layout.class
Here is the above three steps in front of the Log4j components of a simplified; Below is a specific configuration examples, in the light of the implementation process can be:
Log4j.rootLogger = INFO, A1
Log4j.appender.A1 = org.apache.log4j.ConsoleAppender
Log4j.appender.A1.layout = org.apache.log4j.PatternLayout
4r-log4j.appender.A1.layout.ConversionPattern =%% d%-5p (yyyy-MM-dd HH: mm: ssS)% c% m% n
It should be stated here is the log information in the format represented by the symbols of several meanings:
- X: X information output left-justified;
% P:-log information
% D (): log information Generation
% C: Logs site (category)
% M: the log specific information
% N: output log information for firms
According to the above log format, the output of a particular procedure was as follows:
0 INFO 2003-06-13 13:23:46968 ClientWithLog4j Client socket: Socket [addr = localhost/127.0.0.1, port = 8002, 2014 = localport]

JavaServer Face for the Java application development speed.
JavaServer Faces (JSF) is a Java technology used to quickly build Web applications of the new technology. JSF through the provision of the following features to speed up the development process:
Standards and scalable user interface components; vulnerable configuration pages navigation; certification for the importation of components; automation Bean management; incident; easily error handling,
And built-in support of the international.
This paper describes how to use JSF to build online Pisa (pizza) ordering system.
Job description
class=bodycopy> The application is called PizzaRia is an online store that allows users to choose pizza and submit selected pizza. PizzaRia similar with other online stores,
Users can browse the menu, add to the shopping cart and checkout selected products.
The application's user interface from five JSP document composition, they are index.jsp, details.jsp, shoppingCart.jsp, checkOut.jsp and order.jsp.
Each user interface pages, including three other pages: header.jsp, menu.jsp and footer.jsp
Users shopping process: the store to view the goods detailed information, shopping (Add to Cart), checkout, payment.

Database
The procedure of data stored in three forms: products (products), orders (orders) and OrderDetails (orders detailed project). Products Table information storage products, has four: ProductId (product logo), Name (name), Description (Note), and Price (prices).
class=bodycopy style1> Orders table for each row in a separate storage of orders, the information including contact names, addresses and credit card details of delivery. Orders Table 6 are:
OrderId (orders logo), ContactName (contact name), DeliveryAddress (postal address), CCName (credit card belonging name),
CCNumber (credit card numbers) and CCExpiryDate (credit card expiration date).
Each of the detailed project orders in the OrderDetails be stored in the table. OrderDetails table with four: OrderId (orders logo), ProductId (product logo),
Quantity (quantity) and Price (prices). Orders and OrderDetails through OrderID table included one-to-many relationship. Please note that the user table OrderDetails orders on the preservation of the relevant price information. The prices may be different with the current product prices, which stored in the table Products Price column.
In an Oracle database used to create the necessary tables script files stored in pizzaria-oracle.sql pizzaria.zip document.
Business Object
Following is the application used in the business object:
ProductBean package for a product information. It has the following attributes: id (logo), the name (name), description (Note), and price (prices).
Details.jsp each page visited, JSF Implementation (implementation) will automatically create a ProductBean examples. The JSF Implementation call ProductBean
No parameters of the structure, from the database access to the relevant data, and will fill its corresponding word column.
ProductSummary. ProductSummary (Product Overview) for a summary of that product. These include two attributes: id (identification) and the name (name).
ShoppingItemBean. ShoppingItemBean shopping for that item. These include four attributes: productId (product logo), productName
(Product name), the price (price), as well as quantity (number).
ShoppingCartBean. ShoppingCartBean used for storage in a dialogue (session) objects in the cart. Allows users to add such items (using addShopping methods), including all access to a list of items (using getShoppingItems method), and was purchased by the total value of goods (used getTotal methods).
OrderBean. OrderBean said that one orders. Such has the following five attributes: contactName, deliveryAddress, creditCardName,
CreditCardNumber and creditCardExpiryDate.
MenuBean. MenuBean getMenu method showed that the use of products for the directory. The method returns a product contains details of the link to the HTML table.
Package pizzaria;

)
DatabaseUtil. DatabaseUtil provided the following three kinds of methods to access and manipulate data:
- GetProductSummaries: The method returns a product contains a summary table in a list of all products. Overview of a product category to ProductSummary said.
- GetProductDetails: ProductBean the method returns an object, the object identifier package with a specific product details.
class=bodycopy> InsertOrder: The method to the Orders and OrderDetails Table Insert Table customer orders.
Application context sniffers
class=bodycopy style1> Application context sniffers (AppContextListener) read out from the web.xml file access the database for the initial parameters, and then be incorporated into
ServletContext object. The initial use parameters are as follows: jdbcDriver, dbUrl, dbUserName and dbPassword. In your web.xml file edit these values in order to reflect the true value of your database.
Package pizzaria; import javax.servlet.ServletContext; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; public class AppContextListener implements ServletContextListener (/ / web.xml file read Servlet context initialization parameters, construct a DatabaseUtil Object public void contextInitialized (ServletContextEvent event) (DatabaseUtil dbUtil = new DatabaseUtil (); ServletContext servletContext = event.getServletContext (); String jdbcDriver = servletContext.getInitParameter ( "jdbcDriver"); String dbUrl = servletContext.getInitParameter ( "dbUrl"); String dbUserName = servletContext.getInitParameter ( "dbUserName"); String dbPassword = servletContext.getInitParameter ( "dbPassword"); dbUtil.setJdbcDriver (jdbcDriver); dbUtil.setDbUrl (dbUrl); dbUtil.setDbUserName (dbUserName); dbUtil.setDbPassword (dbPassword ); servletContext.setAttribute ( "DATABASE_UTIL" dbUtil);) public void contextDestroyed (ServletContextEvent event) (ServletContext servletContext = event.getServletContext (); servletContext.removeAttribute ( "DATABASE_UTIL");))
JSF application configuration
class=bodycopy style1> JSF allows programmers only through the application process configuration files can be easily configured applications. If the document exists, then it should be named for the faces-config.xml, and should be in your application under the WEB-INF directory.
In the faces-config.xml file in the application's configuration in many aspects, including bean management, page navigation, custom UI (user interface) components,
Custom verification procedures and information resources. In PizzaRia application, I used the faces-config.xml bean management and navigation pages of the configuration.
<? Xml version = "1.0">
Faces-config PUBLIC
"- / / Sun Microsystems, Inc / / DTD JavaServer Faces Config 1.0 / / EN"
"Http://java.sun.com/dtd/web-facesconfig_1_0.dtd">
Incident
In this application, developers need a AppAction Listener called the ActionListener. ProcessAction ActionEvent its way from the target getLocalValue acquire passed to the method of local values. If the local value of "Buy (purchase)," then processAction users with access to relevant ShoppingCartBean objects, and will shoppingItem to join in the bean.

AppActionListener of the use of two very useful approach: getValueBinding and getDatabaseUtil. GetValueBinding accept the designated target of a string, and returns an object of type down conversion ValueBinding type of object. For example, in order to obtain user in the application configuration file to be registered as shoppingCartBean ShoppingCartBean example, developers need to transfer through "shoppingCartBean" to call getValueBinding.
ShoppingCartBean cart = (ShoppingCartBean) getValueBinding ( "# (shoppingCartBean)"). GetValue (facesContext);
GetDatabaseUtil method returns an DatabaseUtil ServletContext of the examples cited:
Private DatabaseUtil getDatabaseUtil () = (FacesContext facesContext FacesContext.getCurrentInstance (); ServletContext servletContext = (ServletContext) facesContext.getExternalContext (). GetContext (); return (DatabaseUtil) servletContext.getAttribute ( "DATABASE_UTIL");) operational procedures: http: / / 127.0.0.1:8080 / pizza / faces / index.jsp

Thank you very much to the monsoon flow interested in statistical systems. Whether you are a beginner JAVA, or JAVA, a master, I am sure you said that the Chinese side JAVA technology development, and even China's software industry development, we must rely on those of us in the software development interested persons.
[Note]
The system is completely open source code, no reservations, no registration, it is completely free. Members prawns may also visit the source code, modify and optimize freedom, as far as possible a better version launched for the large number of users downloaded free of charge. The multi-user system Xiaoxiang Statistics System (asp version) picture, I would like to thank the Internet icon to the Forum provided free of charge, source of technical staff, Thank you.
[Function]
1: Multi-User statistics system to prevent refresh speed, extensive application
2: Comprehensive statistics, a recent visit, regional analysis, address analysis, screen size, page visits, number of visits, the operating system, is online, IP address, browser, the statements, statements, Zhou statements, historical statements, the statements etc.
3: precise tracking of every visitor's IP and online - the same IP online every five minutes to add a count (you can change the time, you stat.jsp page you want to read ExTime time, int ExTime = 5;).
4: to provide detailed IP data packets, allows you to clear the visit is to know where is.
It is always the best, you can monitor who is now in a browser, your web site that you visit the columns
[Configuration]
This directory to the "feng" catalog copy to your virtual directory: \ \ WEB-INF \ classes \ under.
The system used here ACCESS database.
Data Source Name: count, the user name: admin, Password: admin (jdbc.java document can change the code, and then compile).
Database: count.mdb
Preparation of the environment: win2000 + j2sdk1.4.0_02 + tomcat4.0
Test page: test.jsp (you can see the effect of Statistics)
[Management] system
After the completion of the allocation, open system home page, click [management] link, enter your user name, password, if it is the system administrator can then modify, delete, view all the information the website registration, or you can modify, check their website information.
