Hi there,
I?m trying to run na EJB application developed with JBOSS IDE 2.0 and JBOSS
4.0.4 GA. I have an remote stateless session bean named TestStatelessBean that
inherit from TestStateless. Here is the code for them:
package com.test.ejbs;
import javax.ejb.Remote;
@Remote
public interface TestStateless {
public String testBean();
}
----------------------------------------------------------------------------
package com.test.ejbs;
import javax.ejb.*;
import com.test.ejbs.TestStateless;
public @Stateless class TestStatelessBean implements TestStateless {
public String testBean() {
return "the server returned this string";
}
}
------------------------------------------------------------------------------
I have a servlet that calls the EJB:
package com.test.web;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.naming.*;
import java.io.*;
import com.test.ejbs.*;
public class TestStatelessEJBServlet extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
private TestStatelessBean statelessBean;
public void init() {
try {
Context context = new InitialContext();
System.out.println("Before lookup");
// statelessBean = (TestStatelessBean)
context.lookup("TestStatelessBean/remote");
statelessBean = (TestStatelessBean)
context.lookup(TestStatelessBean.class.getName());
System.out.println("After lookup");
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void doGet(HttpServletRequest req, HttpServletResponse
resp)throws ServletException, IOException {
PrintWriter writer = resp.getWriter();
writer.write("The stateless bean returned this string: " +
statelessBean.testBean());
}
public void doPost(HttpServletRequest req, HttpServletResponse
resp)throws ServletException, IOException {
this.doGet(req, resp);
}
}
--------------------------------------------------------------------
If I try to get the bean with the code ?statelessBean = (TestStatelessBean)
context.lookup("TestStatelessBean/remote");? I get a class cast exception.
If try to get the bean with the code ?statelessBean = (TestStatelessBean)
context.lookup(TestStatelessBean.class.getName());? I get a Bean not bound
exception.
I deployed my bean with the JBOSS IDE in the files TestInstallation.ejb3 and
TetsInstallation.war. My project name is ejb3teste. These two files are in
$JBOSS_HOME\server\default\deploy. The content of jndi.properties is:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost:1099
The web.xml file contains:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
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/web-app_2_4.xsd";>
<servlet-name>TestStatelessEJBServlet</servlet-name>
<servlet-class>com.test.web.TestStatelessEJBServlet</servlet-class>
<servlet-mapping>
<servlet-name>TestStatelessEJBServlet</servlet-name>
<url-pattern>/testStatelessEJB</url-pattern>
</servlet-mapping>
</web-app>
The content of the file packaging-buid.xml is:
?xml version="1.0" encoding="UTF-8"?
project name="Packaging Generator" "default="_packaging_generation_"
target name="_packaging_generation_" depends="N65540,N65565"
target name="N65540" description="TestInstallation.ejb3"
jar destfile="TestInstallation.ejb3"
zipfileset dir="src"
include name="jndi.properties"
zipfileset
zipfileset dir="bin" includes="**/ejbs/*"
jar
target
target name="N65565" description="TestInstallation.war
jar destfile="TestInstallation.war"
zipfileset dir="src" prefix="WEB-INF"
include name="web.xml"
zipfileset
zipfileset dir="bin" prefix="WEB-INF/classes" includes="**/web/*"
jar
target
project
In the jmx-console I have:
jboss.j2ee
* jar=TestInstallation.ejb3,name=TestStatelessBean,service=EJB3
* module=TestInstallation.ejb3,service=EJB3
* service=ClientDeployer
* service=EARDeployer
jboss.web
*
J2EEApplication=none,J2EEServer=none,WebModule=//localhost/TestInstallation,j2eeType=Servlet,name=TestStatelessEJBServlet
----------------------------------------------------------
The JNDI Namespace
Global JNDI Namespace
+- XAConnectionFactory (class: org.jboss.mq.SpyXAConnectionFactory)
+- TestStatelessBean (class: org.jnp.interfaces.NamingContext)
| +- remote (proxy: $Proxy58 implements interface
com.test.ejbs.TestStateless,interface org.jboss.ejb3.JBossProxy,interface
javax.ejb.EJBObject)
----------------------------------------------------------------------
I?m calling the servlet with the command line
?http://mymachine:8080/TestInstallation/testStatelessEJB?. I have to use this
URL because the URL ?http://localhost:8080/TestInstallation/testStatelessEJB?
doesn?t work. Do you think this can be the cause of the error?
Thank you very much.
