Hello,
I'm getting ClassCastException while while class (AccountManagerBean) loading from my
ear to a war. I'm pretty sure that I don't have two versions of my class floating
around (which I know can cause such an exception). Any help at all would be appreciated.
Here is the code from the servlet in the war.
Object object = EJB3Finder.lookup(AccountManager.class,
AccountManagerBean.JNDI_LOCAL_BINDING);
|
| AccountManagerBean accountManager = (AccountManagerBean) object;
I'm not doing any scoped class loading. This is a default jboss4.2.1 install with no
changes to the class loading mechanism. The requesting code is in a servlet class in a
war. The war is in the ear. WindowsXP.
I've confirmed by the ucl log that my class (AccountManagerBean) is being found and
loaded by the ear loader, and followed immediately by the ClassCaste as shown below.

Here are my class loading configs in tomcat
<attribute name="Java2ClassLoadingCompliance">false</attribute>
| <attribute name="UseJBossWebLoader">false</attribute>
| <attribute
name="FilteredPackages">javax.servlet</attribute>
Here is the report for a class search via UnifiedRepository mbean in the jmx console,
which proves there is only one instance correct?
