RE : [exoplatform] SOAP NullPointerException [SOLVED]

Hello List,

In case someone is interested, we found the cause of this behaviour. The stack trace sayed that getServiceDescription was not available. That was because, as soon as the WSRP Producer tries to discover the different services, he retrives the <description> tag from the deployment descriptors (web.xml and portlet.xml). We forgot to give this information, so the service could not be described.

Regards,

Alexandre

Objet : [exoplatform] SOAP NullPointerException

Hello List,

I have a problem when I try to acces one of my portlets (let’s say P1) in WSRP mode. Once P1 is deployed I’m not able to create a producer any more.

I use portlet container 1.5 bundled with tomcat.

Here is my stack:

AxisFault

faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException

faultSubcode:

faultString: java.lang.NullPointerException

faultActor:

faultNode:

faultDetail:

{http://xml.apache.org/axis/}hostname:joshua77

java.lang.NullPointerException
