Environmental variables, asked the experts to help look at?
Abstract: The problem of the environment variable, and asked the experts to help look at?
I javac HelloBean.java error in the operation, suggesting that
HelloBean.java: 3: cannot resolve symbol
Symbol: class CreatException
Location: package ejb
Import javax.ejb.CreatException;
Environment variables are as follows:
CLASSPATH: C: / Sun/AppServer/lib/j2ee.jar; C: / bea/wlserver6.1/lib/weblogic.jar
JAVA_HOME: C: / j2sdk1.4.2_10
J2EE_HOME: C: / Sun / AppServer
PATH:
% SystemRoot% / system32;% SystemRoot%% SystemRoot% / System32/Wbem; C: / Program Files / Microsoft SQL Server/80/Tools/BINN; C: / PROGRA ~ 1/Borland/Delphi6/Bin; C: / PROGRA ~ 1/Borland/Delphi6/Projects/Bpl; C: / j2sdk1.4.2_10/bin; C: / Sun / AppServer / bin
/ / Need to introduce this type of class or interface
Import javax.ejb.CreatException;
Import javax.ejb.SessionBean;
Import javax.ejb.SessionContext;
Public class HelloBean implements SessionBean
(
Private SessionContext ctx;
Private String words;
Public void setSessionContext (SessionContext ctx)
(
This.ctx = ctx;
)
/ / And the corresponding definition of the interface method, we must realize
Public void ejbCreate () throws CreateException
(
Words = "Hello Word !!!";
)
/ / Client call for the business logic, here simply print string, the string and return to the client
Public String SayHello ()
(
System.out.println ( "I am in an EJB of Server." + Words);
Return words;
)
)
CLASSPATH
Also.; Dt.jar path; tools.jar path
Gefengxztg:
I would like to ask about, and I dt.jar Add classpath tools.jar path, and still can not find ejb suggested that this package.
New configuration path is as follows:
CLASSPATH: C: / Sun/AppServer/lib/j2ee.jar; C: / bea/wlserver6./lib/weblogic.jar;
C: / bea/jdk131/lib/tools.jar; C: / bea/jdk131/lib/dt.jar
JAVA_HOME: C: / bea/jdk131
J2EE_HOME: C: / Sun / AppServer
PATH:
% SystemRoot% / system32;% SystemRoot%% SystemRoot% / System32/Wbem; C: / Program Files / Microsoft SQL Server/80/Tools/BINN; C: / PROGRA ~ 1/Borland/Delphi6/Bin; C: / PROGRA ~ 1/Borland/Delphi6/Projects/Bpl; C: / j2sdk1.4.2_10/bin; C: / Sun / AppServer / bin;
C: / bea/jdk131/bin
The main problem is not ejb this package.
CLASSPATH: C: / Sun/AppServer/lib/j2ee.jar; C: / bea/wlserver6.1/lib/weblogic.jar wrong should be a plus.
Still inside path to C: / Sun/AppServer/lib/j2ee.jar; C: / join bea/wlserver6.1/lib/weblogic.jar
Wmzsl;
I now re-configuration of a path, but the compiler procedures, or find tips ejb this package, the source is at the top.
New configuration path is as follows:
CLASSPATH:
C: / Sun/AppServer/lib/j2ee.jar; C: / bea/wlserver6.1/lib/weblogic.jar; C: / bea/jdk131/lib/tools.jar; C: / bea/jdk131/lib / dt.jar.
JAVA_HOME: C: / bea/jdk131
J2EE_HOME: C: / Sun / AppServer
PATH:
% SystemRoot% / system32;% SystemRoot%% SystemRoot% / System32/Wbem; C: / Program Files / Microsoft SQL Server/80/Tools/BINN; C: / PROGRA ~ 1/Borland/Delphi6/Bin; C: / PROGRA ~ 1/Borland/Delphi6/Projects/Bpl; C: / j2sdk1.4.2_10/bin; C: / Sun / AppServer / bin; C: / bea/jdk131/bin; C: / Sun/AppServer/lib/j2ee . jar; C: / bea/wlserver6.1/lib/weblogic.jar
Source should be CreateException, missed a e
OK, thank you, ask more than one way, I am now in the machine inside a c: / j2sdk1.4.2_10 and C: / bea/jdk131, What is the difference between them? If I JAVA_HOME variables will be c: / j2sdk1.4.2_10, what would be the difference?
Distinction is a version of a high-end version, if used at the end of version 1.3 can not use, such as 1.4 nio will only emerge when the function, probably it is so
Oh, I would like to thank the.
