Tomcat 6 및 OpenEJB의 EJB 2.0 Jar 3.1.4

Question

I have a simple EJBJar ,Say myHelloEjb.jar 
Having 1.HelloBean.java 
2.HelloObject.java 
3.HelloHome.java 



I put the the jar in Tomcat's lib folder and in Tomcat's examples directory I have a jsp openejb.jsp.Code Snippet : 

InitialContext initCtx = new InitialContext(); 

    Object object = initCtx.lookup("java:comp/env/ejb/Hello"); 
    HelloHome helloHome = (HelloHome) 
      javax.rmi.PortableRemoteObject.narrow(object, HelloHome.class); 
    HelloObject bean = helloHome.create(); 

And added web.xml in examples web-inf folder as : 

     <ejb-local-ref> 
    <ejb-ref-name>ejb/Hello</ejb-ref-name> 
    <ejb-ref-type>Session</ejb-ref-type> 
    <local-home>org.acme.HelloHome</local-home> 
    <local>org.acme.HelloHome</local> 
    </ejb-local-ref> 


When i am calling http://localhost:8080/examples/openejb.jsp 
getting : 

Aug 1, 2011 6:05:08 PM org.apache.catalina.core.StandardWrapperValve invoke 
SEVERE: Servlet.service() for servlet jsp threw exception

and in openejb.log,getting : 

Deployed Application(path=D:\apache-tomcat-6.0.32\webapps\docs) 
2011-08-01 18:06:38,445 - INFO - Configuring enterprise application: D:\apache-tomcat-6.0.32\webapps\examples

Could anybody put some light where did i make mistake ? :(

Answer 1

예제 webapp의 WEB-INF/lib/디렉토리에 myHelloEjb.jar를 넣으십시오.

Answer 2

당신이 쓴 :

<ejb-local-ref> 
<ejb-ref-name>ejb/Hello</ejb-ref-name> 
<ejb-ref-type>Session</ejb-ref-type> 
<local-home>org.acme.HelloHome</local-home> 
<local>org.acme.HelloHome</local> 
</ejb-local-ref> 

---

이 문제는 (되었을 수 있습니다) 될 수처럼 보이는이 : 대신의

<local>org.acme.HelloHome</local> 

:

<local>org.acme.Hello</local> 

아니오?
