Well, this GEF installation is complete.

8, creating a test project

If you have completed all the above steps can now be restarted eclipse, the newly installed plug-in force, officially developed.

1, the use of Sysdeo Tomcat Plugin create tomcat works:

File -> new-> others, open new Wizard dialog box, a tree found in java-> tomcat projects, selected, click the next button. Enter in the projects name textweb, select Use default, click next. The next Talk to maintain the default settings, click finished. At this time, we have the package explorer eclipse will be seen in the new project testweb to create complete.

2, by adding struts framework

File-> new-> others, open new Wizard dialog box, find Amateras-> Struts-> Add Struts Support, select next button click.

Keep the default settings, click the Finish button. Then, in the package explorer eclipse will be seen in the increase in a lot of struts of the library in the WEB-INF also increased under a lot of struts configuration files. In this project we have joined the Struts framework.

3, edit struts-config.xml file

In the WEB-INF folder can be found, right-click menu options open with-> Amateras XML Editer can directly edit the xml text, select open with-> struts-config.xml editor in the graphics mode of documents edit.

On the right side click on the outline of the struts objects can be added into a new object. Here, we note here is a more convenient struts-config.xml file editor, we will be behind the development of a simple small procedures.

4, a new page index.jsp

File-> new-> others, open new Wizard dialog box, find Amateras-> JSP File, click the next button, FileName to index.jsp, click Finish. Then open index.jsp document for editing, as follows:

<% @ Page pageEncoding = "GBK"
ContentType = "text / html;
Gb2312 charset = "%>

<head>
Content = "text / html;
Gb2312 charset = "/>

</ Head>
<body>
<Form name = "form1" method = "post"

action=”/testweb/logincheck.do”>
<Table width = "300" border = "0"

cellspacing=”0″ cellpadding=”0″>
<tr Align="center">
<td Colspan="2"> user login information </ td>
</ Tr>
<tr>
<td> User name </ td>
<td>
<Input name = "username"

type=”text” id=”username”
Size = "12">
User
</ Td>
</ Tr>
<tr>
<td> User passwords </ td>
<td>
<Input name = "password"

type=”text” id=”password”
Size = "12">
123456
</ Td>
</ Tr>
<tr Align="center">
<td Colspan="2"> <input

type=”submit” name=”Submit”
Value = "submit"> </ td>
</ Tr>
</ Table>
</ Form>
</ Body>

5, create data objects form

Open File-> new-> package dialog box, enter com.is.form name, and click Finish button. Package Explorer in the right of the tree to find just the creation package, right-click com.is.form package, the new menu-> others, find Amateras-> struts-> Struts Action Form, click next, in the name in the dialog box LoginForm input column, click Finish button.

Edit the contents of LoginForm categories:

Package com.is.form;
Import org.apache.struts.action.ActionForm;
Public class LoginForm extends ActionForm
(
Private static final long
SerialVersionUID = 1L;
Private String username = "";
Private String password = "";
/ **
* @ Return Returns the password.
* /
Public String getPassword ()
(
Return password;
)

/ **

* @ Param password The password to set.
* /
Public void setPassword (String password)
(
This.password = password;
)
/ **
* @ Return Returns the username.
* /
Public String getUsername ()
(
Return username;
)
/ **
* @ Param username The username to set.
* /
Public void setUsername (String username)
(
This.username = username;
)
)

Note that the two properties were jsp our counterparts in the form of the name of the two input controls, why do so, can look at the struts with the help of documents, I do not detail, also finished form another category attributes, get and set methods can eclipse the source of commands to automatically generate, in the pop-up menu, no detail, to check information on the Internet bar, the use of the eclipse there are many documents.

7, plug-in installed Eclipse HTML Editor

Decompress tk.eclipse.plugin.htmleditor_1.6.7.zip packets, and then copy plugins directory to D: \ eclipse directory covering the original document folder. Eclipse HTML Editor plug-in this installation is complete.

8, plug-ins installed StrutsIDE

Decompress tk.eclipse.plugin.struts_1.1.7.zip packets, and then copy plugins directory to D: \ eclipse directory covering the original document folder.

Well, here StrutsIDE plug-in installed.

6, objects to create action

The same process to create the same form, we are only a com.is.action new package, the same process, opened new wizard, but choose Struts Action, create LoginAction.java type, default value of the election. We edit LoginAction as follows:

Package com.is.action;
Import javax.servlet.http.HttpServletRequest;
Import javax.servlet.http.HttpServletResponse;
Import org.apache.struts.action.Action;
Import org.apache.struts.action.ActionForm;
Import org.apache.struts.action.ActionForward;
Import org.apache.struts.action.ActionMapping;

Import com.is.form.LoginForm;

Public class LoginAction extends Action
(
Private static final long serialVersionUID = 1L;

Public ActionForward execute
(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
Throws Exception (

/ / This line is here for when the
Input page is upload-utf8.jsp,

/ / It sets the correct character
Encoding for the response

String encoding = request.getCharacterEncoding ();

If ((encoding! = Null) & &
(Encoding.equalsIgnoreCase ( "GB2312")))
(

Response.setContentType
( "Text / html; charset = GB2312");

Else ()

Response.setContentType
( "Text / html; charset = GBK");

)

Try (

If (form instanceof LoginForm)
(

LoginForm theForm = (LoginForm) form;

If (theForm.getUsername (). Equals ( "user") & &

TheForm.getPassword (). Equals ( "123456"))
(

Return new ActionForward ( "/ welcome.do? Type = true");

)

Else (

Return new ActionForward ( "/ welcome.do? Type = false");

)

)
) Catch (Exception e)
(

)

/ / This shouldn't happen in this example

Return null;

)
)

Attention here is the direct use of ActionForward to, and you can also provide the blank struts routines struts-blank.war practices in turn, can be compared to the harvest.

7, pages created successful login

Index.jsp with the creation of the same pages, we create welcome.jsp page, use the default settings. And edit its content as follows:

<% @ Page pageEncoding = "GBK"
ContentType = "text / html;
GBK charset = "%>

<head>
Content = "text / html;
GBK charset = "/>

</ Head>
<body>
<%
String type = request.getParameter ( "type");
If (type! = Null & type.equals ( "true")) (
Out.print ( "welcome to you!");

)
Else (
Out.print ( "Sorry, you enter the user name or password wrong!");
)
%>
</ Body>

8, the increase in Struts-config.xml configuration

Add formbean configuration, and labelling between Accession:

<Form-bean

name=”loginForm”
Type = "com.is.form.LoginForm" />

Add jsp document mapping, and labelling between Accession:

Path = "/ index"
Forward = "/ index.jsp" />
Path = "/ welcome"
Forward = "/ welcome.jsp" />

Add action document mapping, and labelling between Accession:

Path = "/ logincheck"
Type = "com.is.action.LoginAction"
Name = "loginForm"
Scope = "request"
Validate = "true" />

After the revised struts-config.xml form along the following lines:

<? Xml version = "1.0">
Struts-config PUBLIC "–
/ / Apache Software Foundation
/ / DTD Struts Configuration 1.2 / / EN "
"Http://struts.apache.org/dtds
/ Struts-config_1_2.dtd ">

<form-beans>
<Form-bean

name=”loginForm”
Type = "com.is.form.LoginForm" />
</ Form-beans>

Path = "/ index"
Forward = "/ index.jsp" />
Path = "/ welcome"
Forward = "/ welcome.jsp" />
Path = "/ logincheck"
Type = "com.is.action.LoginAction"
Name = "loginForm"
Scope = "request"
Validate = "true" />

"Org.apache.struts.tiles.TilesRequestProcessor" />

"Org.apache.struts.tiles.TilesPlugin">
Value = "/ WEB-INF/tiles-defs.xml" />

"Org.apache.struts.validator.ValidatorPlugIn">
Value = "/ WEB-INF/validator-rules.xml,
/ WEB-INF/validation.xml "/>

We can run this test procedure.

9, testing procedures

Right-click testweb project root directory, click on the menu Tomcate project-> update context definition, the project will be deployed into the tomcat, after the success will be prompted to operate successfully.

Click on the menu bar icon Tomcat start tomcat, and then enter the address bar in IE http://localhost:8080/testweb/index.do, we will see index.jsp content pages.
