Integrating confluence wiki portlet

[Robin S., modificado hace 14 años.]

Hi guys,

I'm trying to integrate the confluence wiki portlet into liferay.

The manual is very old though(2007) and links to the files attached there, don't work any more.

Now I go some problems deploying this portlet.
First error message was that the liferay-portlet.xml is missing so I created one and filled it with similar data, I got from other portlets.
Problem is I don't know too much about that portlet.xml-stuff. I attached my portlet.xml and liferay-portlet.xml from this portlet.

Tomcat prints this errormessage on deploy:
