Jboss 4.2 Class Loading

Question

I have a jar in server/default/lib which contains Foo.class , Bar.class

and the same class is there in my application/WEB-INF/classes which is deployed in server/default/deploy .

and Example.class is using the Foo.class instance and Bar.class instance

Now the situation is that Example.class shoud use the Foo.class in my application and Bar.class in default/lib jar file.

ie my application should use the classes in the application clases folder if not found in classes folder then it should use the class in default/lib jar files.

To do i have defined jboss-web.xml file

<jboss-web>
   <class-loading java2ClassLoadingCompliance="true">
   <loader-repository>
         com.example:eagle=web-360.jar
         <loader-repository-config>java2ParentDelegation=true</loader-repository-config>
      </loader-repository> 
   </class-loading>
</jboss-web>

web-360.jar is the jar which will be default/lib . com.eagle:eagle has no significance..

Answer 1

Have a look at JBossClassLoadingUseCases . Your situation seems to be Use Case 4 (ie the class will be loaded from default/lib in preference to WEB-INF/classes .

What you seem to want is Use Case 3 (ie WEB-INF/classes preferred to default/lib ), in which case you should omit the java2ParentDelegation=true config option from jboss-web.xml (or set it to false , which is the default).
