[Php-java-bridge-users] problems with the ejb example

[Raphael V. <rv_...@os...>]

Hi,

I tried to call a EJB from the JavaBridge (2.0.8) as described here:
http://cvs.sourceforge.net/viewcvs.py/php-java-bridge/php-java-bridge/examples/j2ee/README?rev=1.4&view=markup

It results in the following error:

Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke failed: [c:javax.rmi.PortableRemoteObject]->narrow((java.lang.Object)o(CDRInputStream_1_0$1):"com.sun.corba.se.internal.iiop.CDRInputStream_1_0$1:IOR: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!

Line 34 in globals.php is:
$home = $PortableRemoteObject->narrow($objref, $DocumentHome);

After that I tried a similar example with an Session EJB in an OC4J-Container. This does not work as well. The error eccurs in the same method PortableRemoteObject->narrow:

Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke failed: [c:javax.rmi.PortableRemoteObject]->narrow((java.lang.Object)o(__Proxy2):"SessionEJB EJBHome", (java.lang.Class)i:mypackage2.SessionEJBHome). Cause: java.lang.ClassCastException"] thrown in C:\Htdocs\JavaBridge\testClient.php on line 52

Seems so as if the Bridge has problems to cast the EJB to the home interface.

Has anybody tried the example successfully?

Hi,

I have just tried this with the sun j2ee sample
server, narrow correctly returns the stub there:
[o(_DocumentHome_Stub):"IOR:00000000..."]

So this problem seems to be oc4j specific.  I have
tried to deploy the sample.jar into oracle but I have
given up for the moment because this AS doesn't accept
plain .jar files; I think I'll have to create a .ear
first.

This ClassCastException rings a bell, however.  Do you
use the j2ee.jar from oracle or from sun?

I think this is a oracle specific problem and doesn't
have anything to do with the bridge. -- If I remember
correctly, this error appears if one mixes the  j2ee
jar files from different vendors. We have wasted
several hours, but I cannot remember how we solved
this problem.


I will check this, asap.  Please see PR1308217 for
details:

Hi,

thanks for your reply.

My first test was with the Sun AS (Version 8.1_02 (build b06-fcs)).
I followed the tutorial step by step. Which mode do you use for the 
JavaBridge? Does it run in an AS or standalone? This is the only 
difference I could imagine.

For this example I have used the j2ee.jar from sun which was delivered 
with the Application Server.

For the Test with the OC4j Container I used the oc4j.jar which has a own 
implementation of the necessary classes and interfaces.

It runs as standalone with the generated ejb client
jar and the sun j2ee jar in the java_require() path.
Whether or not it runs inside the AS shouldn't make a
difference as long as the correct client and j2ee jars
are used.

Okay, and where does the client jar come from, does it
contain the stub classes? I have just tested this with
the client jar generated from the deploytool, this
works on oracle, too, without generating a class cast
exception.

Can you please attach the client jar at the end of the
ticket?


BTW, if I remember correctly, oracle doesn't need the
narrow, because it uses wrapper instead of a proxy. So
you could simply ommit the narrow and the example
should work.  But that's an oracle specific "hack"
which will not work with other servers.

I used the documentBeanClient.jar which was shipped with the example. 
After generating a new with the deploytool it works!

Thanks for the hint.
