JBOSS 4.0.2 and EJB 2.1 - simple application - not working

[lingareddy]

I am doing first ejb program on jboss 4.0.2. i deployed ejb module successfully. but client program (web application ) giving error. i am trying to call local ejb.


Error

javax.naming.NamingException: ejb-local-ref: 'ejb/ejb2', with web.xml ejb-link: 'HelloBean' failed to resolve to an ejb with a LocalHome)

ejb-jar.xml

<enterprise-beans>
 <session>

 <ejb-name>alr</ejb-name>
 <home>com.HelloHome</home>
 <remote>com.Hello</remote>
 <local-home>com.HelloLocalHome</local-home>
 <local>com.HelloLocal</local>
 <ejb-class>com.HelloBean</ejb-class>
 <session-type>Stateless</session-type>
 <transaction-type>Container</transaction-type>
 </session>
 </enterprise-beans>
</ejb-jar>

<ejb-local-ref>
 <ejb-ref-name>ejb/alr</ejb-ref-name>
 <ejb-ref-type>Session</ejb-ref-type>
 <local-home>com.HelloLocalHome </local-home>
 <local>com.HelloLocal</local>
 <ejb-link>HelloBean</ejb-link>
 </ejb-local-ref>

jboss-web.xml

<ejb-ref>
 <ejb-ref-name>ejb/alr</ejb-ref-name>
 <local-jndi-name>jndi</local-jndi-name>

 </ejb-ref>

client jsp page

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,
 "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
props.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099");


 Context ctx = new InitialContext(props);

 System.out.println("It;s ok");


 HelloLocalHome home=(HelloLocalHome) ctx.lookup("java/env/ejb/alr");
 HelloLocal bean = home.create();
 String hello= bean.hello();
 bean.remove();
 ctx.close();

What is the wrong in above code. Please tell me. I have been trying for this.

some issues:

1. If i don't write optional jboss.xml what is the optional jndi name for jboss4.0.2

2. while calling local ejb on same machine, jndi properties are not required. can you confirm?


Advanced thanks. Please give answer

From the web.xml, remove this:

<ejb-link>HelloBean</ejb-link>

[lingareddy]

 nested throwable: (javax.naming.NamingException: ejb-local-ref: 'ejb/alr', no ejb-link in web.xml and no local-jndi-name in jboss-web.xml)

If i remove ejb-link i am getting above error. could you tell jndi configuration for local bean and remote bean. Advaced Thanks!

Just looked at your post again. Your jboss-web.xml contents is incorrect:

<ejb-ref>
 <ejb-ref-name>ejb/alr</ejb-ref-name>
 <local-jndi-name>jndi</local-jndi-name>

 </ejb-ref>

This should be a ejb-local-ref and not ejb-ref. Change it to:

<ejb-local-ref>
 <ejb-ref-name>ejb/alr</ejb-ref-name>
 <local-jndi-name>jndi</local-jndi-name>

 </ejb-local-ref>

Hi Friends,

Still i have beeen strugging to find solution.


I am running the local ejb from command prompt in same JVM. For this no need jndi.properties file and jboss.xml. Pleae cinfirm it. Direct i am looking home interface in look up.

setting following jar files at command prompt.

set path=path%; c:...

set classpath=%classpath;
C:\jboss-4.0.2\jboss-4.0.2\server\default\lib\jboss-j2ee.jar;
C:\jboss-4.0.2\jboss-4.0.2\server\default\lib\jboss.jar;
C:\jboss-4.0.2\jboss-4.0.2\server\default\lib\jboss-transaction.jar;
C:\jboss-4.0.2\jboss-4.0.2\server\default\lib\jnpserver.jar;
C:\jboss-4.0.2\jboss-4.0.2\server\default\lib\jboss-common.jar;

Confirm these jars are enough or any jar is missed?



But it is not working.


Please kindly provide client jndi looku up code for local bean calling at command prompt and jar file required for jnoss 4.0.2 to rin ejb 2.1 at clinet?
