EAR deployment in jsp the import Class cannot be resolved when library exists

[duanxz]

Hi，

my ear to deploy on jboss-5.1.0.GA is ok. When I'm trying to deploy on AS 6.0 Final i am receiving an "org.apache.jasper.JasperException: Unable to compile class for JSP:An error occurred at line: 6 in the generated java file
The import com.aqqfpo.server cannot be resolved"in the deployment of AEM.war ,although the library exists in the ear lib directory.
Any help with this will be greatly appreciated.

The ear format is as follows:
aqqfposerver.ear
|
|---AEM.war
|
|---aqqfpo.war
|
|---aqqfposervlets.war
|
|---aqqfposerver.jar
|
|---APP-INF
|      |
|      |--classes
|      |--lib(公用的第三方类struts,aqqfposerver.jar)
|
|---META-INF
|      |
|      |-- MAINIFEST.MF
|      |--application.xml

Here is my application.xml：
***********************************
  <module>
    <ejb>aqqfposerver.jar</ejb>
  </module>
  <module>   
    <web>     
      <web-uri>AEM.war</web-uri>

Hi,

does your .war file contain a file "META-INF\MANIFEST.MF" with this content:

Manifest-Version: 1.0

Class-Path: aqqfposerver.jar

Hope this helps

Wolfgang

Thanks, Wolfgang.your help is much appreciated.
1 made the AEM\META-INF\MANIFEST.MF as you suggested above, when i visit http://localhost:8080/AEM/    still  receiving the same error.
"org.apache.jasper.JasperException: Unable to compile class for JSP:An error occurred at line: 6 in the generated java file The import com.aqqfpo.server cannot be resolved".

when visit http://localhost:8080/servlet ,this part is ok.why?

Any help with this will be greatly appreciated.

I don't see any .ear/lib/*.jar in the first post of this topic. Where exactly is that jar containing the class located?

[duanxz]

Thanks, jaikiran.
first,I use the command jar-tf with aqqfposerver.ear, the results are as follows.

The APP-INF folder isn't a spec specified location. It isn't recognized by JBoss AS. So move all those jars from APP-INF/lib  to .ear/lib.

[duanxz]

Thank you jaikiran.
I am now at home after work tomorrow I will be the first time in the test as you suggest.

[duanxz]

Hi,jaikiran. thanks for your help again.
i  changed the directory structure as follow,and add "Class-Path: aqqfposerver.jar" in " AEM\META-INF\MANIFEST.MF".
the problem still exists.

Hi,

you have "aqqfposerver.jar" in two locations of your EAR: at root level (that's correct) and in the "lib" subdirectory. Remove it here.

A file "META-INF/weblogic-application.xml" will have no effect for JBoss, so remove it.

And the "<library-directory>" xml fragment in "MANIFEST.MF" is also wrong.

And now to more questions: could you also post the output of "jar -tf AEM.war"?

Best regards

Wolfgang

[duanxz]

Thanks,Wolfgang.

First of all that, this project will be run to the WAS, EAServer, JEUS, the prior i think does not affect deploy under  jbossAS6, so there is no delete weblogic-application.xml.
now i removed this(weblogic-application.xml), the configuration files and directory structure as follows:

My operation is: AEM.war above extract from the aqqfposerver.ear out, and then jar-tf AEM.war command.

Thanks a lot for your help and tips.

[duanxz]

hi,Wolfgang.
I do not know the above "jar-tf AEM.war" operation is correct,

but in the result is not found the class[<%=com.aqqfpo.server.config.AqqfpoConfig.getServerVersion()%>] to be used in JSP files.

[jaikiran]

By any chance, are you on a Windows operating system?

[duanxz]

Thanks jaikiran。
my system info:OS-System: Windows 7 6.1,x86，
this project under jboss-5.1.0.GA is ok，i will try in other windows operating system in tomorrow。
thank you again.

[jaikiran]

I think you are running into a case sensitive bug. Do you have com.aqqfpo.Server.class (yes .class) in any of the jars? See this for further information https://community.jboss.org/message/563416#563416

[wolfgangknauf]

Hi Duan,

where is the class "com.aqqfpo.server.config.AqqfpoConfig" found? Probably in "aqqfposerver.jar"?

By the way: be careful to extract an EAR file in the JBoss deploy folder - the server might consider it an exploded deployment now and deploy some stuff duplicate (with errors). Do this only if the server is stopped, and delete if afterwards.

One small question about this JAR: it is probably an EJB jar (containig EJBs), or is it a simple utility JAR?

If it is an EJB jar, then all my previous suggestions are OK. If it is an utility JAR, there are differences ;-).

Your "jar-tf AEM.war" command seems to be correct, but I would like to see some more details:

-is a "WEB-INF\lib" directory present? If yes: please post the content.

-post the content of META-INF\Manifest.mf (just to be sure that there is no typo)

Best regards

Wolfgang
