Hi all!

I'm using Mule 2.1.2 that receives a message from a VM, and send the answer
to a ejb container in Weblogic.

Everithing works fine, but when it tries to send the message to the ejb
endpoint, always returns me a NullPointerException on Hashtable:396, and
when i see the trace, it seems to be an error with the setParameter method.

I return an String from the component... and i define the method arguments
on the outbound.

The configuration is:

<description>
Componente simple para la entrada al servicio de gestion de usuarios y su
acceso al webservice
</description>

<spring:bean name="jndiContext" factory-bean="jndiFactory"
factory-method="create"/> -->

<ejb:connector name="weblogicEjbConnector"
jndiInitialFactory="weblogic.jndi.WLInitialContextFactory"
jndiProviderUrl="t3://10.16.105.183:7001" >
</ejb:connector>

<cxf:connector name="cxf"/>

<spring:bean id="fEntrada" class="filtros.FiltroEntrada" />

<model name="echoSample">
<service name="EchoUMO">

<inbound>
<vm:inbound-endpoint path="1">
<filter ref="fEntrada"/>
</vm:inbound-endpoint>
</inbound>

</model>
</mule>

The stacktrace is:

44500 [weblogicEjbConnector.dispatcher.1] ERROR

I'm not much of an EJB user but the message:

Failed to connect/reconnect

makes me think that perhaps Mule is not connected to 10.16.105.183

Hi Antoine,

It must be a problem with the outbound. I tried to put another component
acting like a EJB client and it's works fine.

The ejb-connector works fine, because when i down the server, it fails
trying to connect to the t3 server. It must be a problem with the
ejb:outbound then...

Thanks anyway. I will try another ways to do that.

Bye!

You didn't set a securityPolicy on your ejb connector.

See [http://www.mulesource.org/display/MULE2CB/Integration+with+BEA+WebLogic] for an example.

Success,
Mario
