jboss 7 jndi error

[vamshi.a]

Below is the packaging which works in jboss6 but fails in JBOSS7

1)mymoduleapi.jar  this module contains interface which is implemented in ejbs

2)mymoduleejb.jar this module implements session bean with interface defined in mymoduleapi.jar

3)mymoduleear.ear this module contains the mymoduleapi.jar and mymoduleejb.jar as shown below

mymoduleear.ear

       |

       |__lib/mymoduleapi.jar

       |

       |__mymoduleejb.jar

4)mymoduleweb.war this module contains servlet which calls the business logic. The packaging for this module is shown below

mymoduleweb.war

         |

         |__WEB-INF/lib/mymoduleap.jar

5)I have adjusted my servlet to use the jboss7 JNDI convention

6)When I deploy the ear ,war and try to invoke servlet which intern invokes the business logic I get the following error

java.lang.ClassCastException: com.abc.api.service.DepFinderService$$$view1 cannot cast to com.abc.api.service.DepFinderService

Any suggestion on how to solve this problem.

look my answer here http://community.jboss.org/message/629776#629776

it worked for me, said in 2 words: put the interfaces in jboss modules instead in the 2 packages (ear and war), add the Dependencies entry

it is not what's expected but a workaround

bye

If you deploy war outside of ear it gets its own classloader in JBoss 7. You get the same interface loaded twice by different classloaders, one in ear and one in war. You can not cast one to another. You can refactor interface to a separate module as suggested above, or just include your war into ear and remove api.jar from WEB-INF. This is a good link about it: https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7
