This is the portlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<portlet-app version="1.0" xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd">


<portlet-name>Jsr286EventPublisherPortlet</portlet-name>

<event-definition>
<qname xmlns:x="http://portal.be/events">x:contactInfo
<value-type>be.portal.ContactInfo</value-type>
</event-definition>
</portlet-app>

This is the code used to send the event:

// Send the event using the appropriate QName
response.setEvent(new QName("http://portal.be/events", "contactInfo"), contactInfo);

The ContactInfo class has been annotated with @XmlRootElement

Don't see what I'm doing wrong here...

Thanks

If the portlet is simple enough can you send it to me by email ?

[depauwl]

I found the problem, there was also a wsrp portlet on the same page when I remove this portlet the event is generated succesfull.
Now I get a class cast exception on the event payload class... in the event listener portlet... class and package name are the same and the class is provided in a jar in both war archives...

[theute]

Can you post the stacktrace ?

[theute]

I got your email with sources.

The issue here is that you have 2 wars and you include the (same) jar containing the payload class in the 2 wars.

They are in 2 different classloaders and then it fails to cast it. (See http://wiki.jboss.org/wiki/ClassLoadingOverview

I will look at the issue with WSRP and events thanks for the feedback !

[theute]

I fixed the issue with WSRP, thanks a lot again for the feedback and please don't stop ;)
