Running EJBs, JSC applications together in JBoss 4.0.1SP1

Question

This is not a question. It is just an example, in case somebody has some problem to run EJBs and JSC applications together in Jboss. Maybe this is a wrong place, but I did not know a better place. Sorry.
Due to classloader issue, the following discussion will focus on JBoss 4.0.1SP1. And JSC version is 2 update 1.
Setup JBoss 4.0.1SP1 to run JSC applications
* Install JBoss 4.0.1SP1.
* Copy jstl.jar and standard.jar from the $CREATOR_INSTALL_DIR/enterprise1/config/TagLibraries/JSTL11 directory to $JBOSS_HOME/server/default/deploy/jbossweb-tomcat50.sar directory. Same to $JBOSS_HOME/server/all/......
* Some on-line discussions mentioned that we should delete $JBOSS_HOME/server/default/deploy/jbossweb-tomcat50.sar/jstl-libs directory. However, I did not see this directory. Because it does not hurt, I deleted tmp and work subdirectories under $JBOSS_HOME/server/default (and all).
Deploy EJBs in Java Studio Creator
* Remove all other files from META-INF in the .jar file. Only keep ejb-jar.xml. If you have an Entity bean you also need to keep jbosscmp-jar.xml.
* Start Sun Java Studio Creator and start the application server.
* Go to $Creator/SunAppServer8/bin and invoke "deploytool".
* Expand node servers and click "localhost:25848" (Creator 2 is 24848).
* In the login window login using admin/adminadmin.
* Choose File -> Open, and open the EJB jar file.
* Choose Tools -> Deploy, and also check the Return Client Jar box .
* In Creator's Server panel, right-click on the Enterprise Beans and select Add Set of Session EJBs
* Please note the RMI port number is 24700 for JSC 2 update 1.
* Click Add button to add the Client.jar you saved when deployed the EJB to Sun Application Server
* Click Next and then Finish. The new EJB should be available.
Call EJBs in Creator
Assumption:
1. The session bean name is HelloBean and the jar file is Hello.jar;
2. The war file is Hello.war.
The simplest deployment description is as follows
ejb-jar.xml:
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">

<enterprise-beans>
<session>
<display-name>HelloSB</display-name>
<ejb-name>HelloBean</ejb-name>
<home>com.whatever.HelloRemoteHome</home>
<remote>com.whatever.HelloRemote</remote>
<ejb-class>com.whatever.HelloBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
</enterprise-beans>
<assembly-descriptor>
<container-transaction>
<method>
<ejb-name>HelloBean</ejb-name>
<method-name>*</method-name>
</method>
<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>
</ejb-jar>
web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.co

<ejb-ref-type>Session</ejb-ref-type>
<home>com.whatever.HelloRemoteHome</home>
<remote>com.whatever.HelloRemote</remote>
<ejb-link>Hello.jar#HelloBean</ejb-link> <!-- This should be added manually -->
</ejb-ref>
</web-app>
* When creating a session bean, either Eclipse or NetBeans is good enough.
* When exporting a WAR file from JSC, select J2EE 1.4.
* With the above deployment descriptors it is not necessary to deploy an EAR file. In other words, both .jar and .war files can be deployed separately.
* When deployed to Sun Application Server, the EJB's sun-ejb-jar.xml should contain <jndi-name>ejb/HelloBean</jndi-name>. This results in JNDI lookup(�java:comp/env/ejb�); otherwise, it would be �java:comp/env�.
* The SessionBeans deployed to JBoss and Sun Application Server can be different, but the signatures should be the same. When I did my first prototype, the SessionBean was hardcoded and did not access the database. However, in JBoss I had both Session Beans and Entity Beans.
* When you have more than one .war file, you can move library .jar files from WEB-INF/lib to $JBOSS_HOME/server/your_server/lib. That way you can avoid many WARNING messages in JBoss' server.log.

Answer 1

hi,i deploy ejbs & web app on jboss-4.0.2 as your method ,but throw exception
java.lang.ClassCastException
     at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229)
when call ejb's method.
That's ok when running on sun appserver 8.
why?
