help with ClassCastException
Hi,
I'm getting a class cast exception when attempting to create an instance of my LocalHome object that I have not been able to figure out. It's probably something pretty simple, but I just haven't been able to see it. I'm using JBoss 4.0.3.
Here's the code that is being executed in my servlet:
Object obj = null;
try
{
obj = ctx.lookup("java:comp/env/FSCApplicantLocal");
FSCApplicantLocalHome fsc_applicant_home = (FSCApplicantLocalHome)PortableRemoteObject.narrow(obj, FSCApplicantLocalHome.class);
applicant = fsc_applicant_home.findByPrimaryKey(new Long(quoteNo));
}
catch(Exception _e)
{
_e.printStackTrace();
throw _e;
}
Here's the jboss.xml:
<ejb-name>FSCApplicantBean</ejb-name>
<local-jndi-name>ejb/local/FSCApplicantLocal</local-jndi-name>
<ejb-local-ref>
<ejb-ref-name>FSCApplicantLocal</ejb-ref-name>
<local-jndi-name>ejb/FSCApplicantLocal</local-jndi-name>
</ejb-local-ref>
Here's the ejb-jar.xml:
<![CDATA[FSC Applicant Entity Bean (CMP)]]>

Here's the web.xml:

<local-home>com.InsureSuite.FSCExport.FSCApplicantLocalHome</local-home>

<ejb-link>FSCApplicantBean</ejb-link>
</ejb-local-ref>
Here's the jboss-web.xml:
<ejb-local-ref >
<ejb-ref-name>FSCApplicantLocal</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<local-home>com.InsureSuite.FSCExport.FSCApplicantLocalHome</local-home>
com.InsureSuite.FSCExport.FSCApplicantLocal
<ejb-link>FSCApplicantBean</ejb-link>
</ejb-local-ref>
And finally, here's the stack trace:

Any help would be appreciated.
Thanks,
