Dear reader,
I've been trying to let Tomcat remotely call an EJB (Enterprise Java Bean) from a JSP
page. But so far without any result (but many different exceptions). I am new to
Tomcat, so I guess I am missing something somewhere.
Tomcat runs in a separate JVM and so does the default J2EE server (so basically 2
different locations). The EJB deployed at the J2EE servers JNDI name is ejb/AuthorRef.
I've created a simple web.xml file that goes with the JSP, which content is:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>
<!-- EJB Reference -->
<ejb-ref>
<description>Author Bean</description>
<ejb-ref-name>ejb/AuthorRef</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<home>ejbbeans.AuthorHome</home>
<remote>ejbbeans.Author</remote>
</ejb-ref>
</web-app>
The code in the JSP I used to locate the EJB is:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.enterprise.naming.SerialInitContextFactory");
env.put(Context.PROVIDER_URL, "iiop://127.0.0.1:1050");
env.put("java.naming.factory.url.pkgs","com.sun.enterprise.naming");
InitialContext context = new InitialContext(env);
Object ref = context.lookup("java:comp/env/ejb/AuthorRef");
The last line (of the code) causes an exception. Such as "object not bound to this
Context" and alike. I don't know what I am doing wrong, or what I should do different
as I haven't found any good documentation about this subject. I hope someone knows
what I should do. I am really stuck now.. at Suns Java forum no-one seems to know
either... Thanx a lot in advance!
Regards Martijn
