Description

Because Our Applicationserver optimizes the web accesses throug the webdav-api to local transaction, we are trying to use a servlet filter that wraps a Usertransaction around every http requests. This results in the use of Glocal transactions. So far so good, it works in all normal jackrabbit accesses. But not with observation events! In case of event listening on repository changes the folowing exception occures:

[11/19/12 12:41:24:421 CET] 000000a3 servlet E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: An exception was thrown by one of

I hope that somebody can help us solving/working around this one! We would be willing to do the testing an debugging if necessary. But we do not have the time to dig into the code and solve it ourself.
If somebody helps us getting Jackrabbit running XA under Webspere, i will go to the Management and try to get a donation to Apache-Jackrabbit.
