Subject [jira] [Commented] (JCR-3475) Workaround force LocalTX to a GlobalTX with a UserTX throws Exception in Events
Date Wed, 05 Dec 2012 07:13:01 GMT

    [ https://issues.apache.org/jira/browse/JCR-3475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13510328#comment-13510328
] 

Richard van Nieuwenhoven commented on JCR-3475:
-----------------------------------------------

How can Jackrabbit work with xa under websphere, when it does not support local tx? We (IBM
support included) found no possibility to force Websphere to global Transactions.

The only solution i found (with websphere support and long web searches) was to turn off the
XA transactions in the ra.xml of jackrabbit. As far as i understand it that means that Jackrabbit
does not participate in XA transactions.

When there is an other solution, or if i am wrong in my assumptions please post it.

> 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:

> 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.
