NullPointerException when JNDI lookup for remote bean
I deploy a stateless bean on apache-tomee-1.0.0-beta-2-plus.
But when I try to get the remote interface a NullPointerException is
throwed.
I do not have this problem with previous version of OpenEJB (version 3.14 on
tomcat 6.0.29)
Test client:
...
Properties p = new Properties();
p.put("java.naming.factory.initial",
"org.apache.openejb.client.RemoteInitialContextFactory");
p.put("java.naming.provider.url", "http://localhost:8080/openejb/ejb");
InitialContext ctx = new InitialContext(p);
MyBean myBean = (MyBean) ctx.lookup("MyBeanRemote");
...
Exception at ctx.lookup(..):
java.lang.NullPointerException

Any idea ?

I've found the problem! An old version of the openejb-client was defined as
dependency in the client application. With 4.0.0 it works like a charm.

Hi,
can you tell me how to enable the ejbd:// support?
I made you a simplified example: http://uploaded.net/file/9nh2j6a6
The archive contains a readme.txt describing the files.
I'm exited what do you will see :D

Well in tomee ejb isnot active by default but your issue is relative to the
jndi name you use IMO
Which one is it?
Can you reproduce the issue in a sharable project?

Have someone had the same problem? I'm using tomee 1.5.1 and I can't look up
a remote bean either:
java.lang.NullPointerException
at
org.apache.openejb.client.JNDIContext.createBusinessObject(JNDIContext.java:188)
at org.apache.openejb.client.JNDIContext.lookup(JNDIContext.java:232)
at javax.naming.InitialContext.lookup(InitialContext.java:411)
at [...]
That's the configuration of my ContextFactory:
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
props.put(Context.PROVIDER_URL, "http://"+server+"/tomee/ejb");
I've tried before to use ejbd protocol ("ejbd://127.0.0.1:8080") but this
have not worked ...
Can someone help me?
Best regards
Superhans

Hi,
are you sure your bean is deployed with this name?
