Hi all,
I'm trying to deploy a Session bean on JBoss.
My java classes as follows:
pkg1.MyBean //Bean
pkg1.My //Remote Interface
pkg1.MyHome //Home Interface
pkg1.MyLocalHome //Local Home Interface
pkg1.MyLocal //Local Interface
ejb-jar.xml related codes:
<!-- Session Beans -->
<![CDATA[A session bean named My]]>
<display-name>My</display-name>
<ejb-name>My</ejb-name>
pkg1.MyHome
pkg1.My
<local-home>pkg1.MyLocalHome</local-home>
pkg1.MyLocal
<ejb-class>pkg1.MySession</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
jboss.xml related codes:
<enterprise-beans>
<ejb-name>My</ejb-name>
<jndi-name>My</jndi-name>
<local-jndi-name>MyLocal</local-jndi-name>
<method-attributes>
</method-attributes>
</enterprise-beans>
then I'm trying to call the Bean using JSP page
JSP page code:
<%!
private My my = null;
public void jspInit() {
try {
InitialContext ic = new InitialContext();
Object objRef = ic.lookup("My");
MyHome home = (MyHome)PortableRemoteObject.narrow(objRef,
MyHome.class);
my = home.create();
} catch (RemoteException ex) {
System.out.println("Couldn't create My bean."+ ex.getMessage());
} catch (CreateException ex) {
System.out.println("Couldn't create My bean."+ ex.getMessage());
} catch (NamingException ex) {
System.out.println("Unable to lookup home: "+ "My "+
ex.getMessage());
}
}
public void jspDestroy() {
my = null;
}
%>
when I'm try to execute jsp page.
I got following Exception:
