check this out: JBossIDE Tutorial 1.4, page 34, section 9.3, start from 3rd paragraph. Verify if you followed this tutorial and notice the 6th paragraph where it says: "The classes must be located under the WEB-INF/classes of the War package. Set the prefix to WEB-INF/classes." You can try to remove the entry on Prefix, it should be blank, and try to run Packaging again and re-deploy your FiboApp.ear and try Fibo again. Hopes this help. Mine is now working after 3 days of almost on the brink of insanity. S My current config: OS: WXP SP4 JBossIDE: JBossIDE-1.5M1-jre15-win32.zip Java: 1.5.0_3 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3877107#3877107 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3877107 |

I removed the WEB-INF/classes from packaging info as above, and it worked, thanks a million. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3885806#3885806 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3885806 |

Hi,
In ComputeServlet.java I changed the following line from:
Object ref = context.lookup("java:/com/env/ejb/Fibo");
to:
Object ref = context.lookup("ejb/Fibo");
and Run Packaging and everything was fine.
I also had to use jboss-4.0.1 instead of jboss-4.0.2
Regards.

Hi, the correct URL should be "java:com/env/ejb/Fibo". If you get an exception like "ClassCastException" when narrowing the reference to the homeInterface, have a look at the AdminGuide Chapter 2 (Server Config.) and change some Config-Flags, making the server J2EE-1.4 compliant. I did this with Version 4.0.2 and 4.0.3RC1 and the tutorial example (jBossIDE) worked fine!

Would anyone explain why removing WEB-INF/classes can solve the problem? Thanks! View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3891383#3891383 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3891383 |

Please, could anyone explain me Helmut's solution? What do I have to do, to get rid of this classCastException? What configuration files do I have to change? Thank you very much!

This is basically a classloading problem. The new JBoss does not have a flat classloader like the old JBoss. So if you load a class in your EJB and you load a class in your servlet even though the bytecode is the same they are treated as diffrent classes. So for the tutorial to work you should remove the FiboEJB-client.jar from your FiboWEB.war file. Your servlet will reference the class FiboHome from the FiboEJB.jar file. After 2 days of digging into the code. IRC channels web searches. I finally managed to get the applcation working. There is also a problem with the Discriptor Wizard but if you type in all that is written in the tutorial it should work. @jboss.xxxx tags also did not work for me. I just typed it in. From all this the lession I learnt was "There is no substitute to hard work" if you have any problems you can mail me. I know your plight. I've been there. Ciao Some of the sites I visited to know more of the problem. http://www.jbossgroup.com/index.html?module=bb&op=viewtopic&p=3887843 http://jira.jboss.com/jira/browse/JBAS-1775 http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration http://jira.jboss.com/jira/browse/JBAS-1691 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3901970#3901970 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3901970 |

Just confirming that I had the classloader problem and ThomasRamapuram's solution of removing the client jar from the war worked perfectly. Wish I found this thread sooner!! thanks!

Removing the WEB-INF/classes did the trick for me, thanks for the tip!!! After looking at the project tree on disk I found that there was no such directory, the classes are in the Tutorial/bin/ejb, Tutorial/bin/interfaces and Tutorial/bin/web directories. This explains why you have to leave it blank, everything is found relative to the class directory Tutorial/bin. Cheers, Roel.

After reconcidering a while, I think this is not the real reason, because the prefix indicates where the classfiles are in the .war file... So somewhere else down the line there is a discrepancy, perhaps in the web.xml file?
<ejb-ref >
<![CDATA[Reference to the Fibo EJB]]>
<ejb-ref-name>ejb/Fibo</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
tutorial.interfaces.FiboHome
tutorial.interfaces.Fibo
</ejb-ref>
Well, I'm not sure, just starting my way into this wonderful world of EJB's :-)
