Subject: How to call a remote EJBean from a Servlet/JSP using j2ee server
Hi all,
I'm back. I think something is wrong somewhere. Let me explain what I'm
trying to achieve.
Reading thru Writing Enterprise Application with J2EE(Monica Pawlan, Sept
27th 2000 ) I build the very first example with CalcBean. After I run in
locally(localhost) using j2ee server from Sun I tried to deploy the bean to
a different machine.
I renamed the JNDI name for the one was locally deployed. I've redeployed
the application made from a web tier( on single Servlet and one single html
file) and the unused session stateless bean on my machine.
I've created a second application made only from the bean described above
and I deployed on the second machine. The JNDI name for second one is
"calcs".
When I'm trying to run it the lookup fails - the name "calcs" given to the
second bean is not visible.
(javax.naming.NameNotFoundException: calcs not found)
Here is the init method where it fails.
public void init(ServletConfig config) throws ServletException{
//Look up home interface
try
{
//InitialContext ctx = new InitialContext();
//new code
Properties p = new Properties();
p.put(Context.PROVIDER_URL, "iiop://ddd.ddd.ddd.ddd:1050");
InitialContext ctx = new InitialContext(p);
Object objref = ctx.lookup("calcs");
homecalc = (CalcHome)PortableRemoteObject.narrow(objref,
CalcHome.class);
}
catch (Exception NamingException)
{
NamingException.printStackTrace();
throw new ServletException( NamingException );
}
}
An additional test I've replace ddd.ddd.ddd.ddd with my IP address and
rename calcs with the name of the "local" EJB and it worked just fine.
I have now some doubts about some security issues(policies) that I have to
take care of.
If anyone had ever a similar problem, please give me a hint to move on.
Thanks.
Regards,
Mircea
