Hi all,
I'm trying to create a new restlet and when I'm sending requests according to
it's URL pattern I receive a NullPointerException.
My restlets-contrib.xml looks something like this:
<?xml version="1.0"?>
<component name="comp_name">
<extension
target="org.nuxeo.ecm.platform.ui.web.restAPI.service.PluggableRestletService"
point="restlets">
<restletPlugin name="restletName"
class="RestletClass"
enabled="true" useSeam="true" useConversation="true">
<urlPatterns>
<urlPattern>
/{pattern}/restletName
</urlPattern>
</urlPatterns>
</restletPlugin>
</extension>
</component>
And the stack trace I get is:
java.lang.NullPointerException

Does anyone have any idea?
Also in Nuxeo book is states that conversationnal restlets must be called with
a convesationId as parameter. The client I'm using to feed the restlet is a
standard java application. Do you have any idea how can I get a valid
conversation id and attach it to my requests?
Thanks in advance
