[jira] Created: (CARGO-714) Tomcat transaction resource is defined globally, which doesn't work in tomcat 5.5 or 6

Tomcat transaction resource is defined globally, which doesn't work in tomcat 5.5 or 6
--------------------------------------------------------------------------------------

                 Key: CARGO-714
                 URL: http://jira.codehaus.org/browse/CARGO-714
             Project: Cargo
          Issue Type: Bug
          Components: Tomcat
    Affects Versions: 1.0
            Reporter: James Roper


In cargo 1.0, tomcats resources are all defined globally (in conf/context.xml).  This doesn't work for transaction resources in tomcat 5.5 (or it seems 6).  See this thread for some details:

http://www.nabble.com/UserTransaction,-JOTM-and-Tomcat-5.5.x-td2793244.html

Additionally, defining resources globally means that two deployments that require different datasources with the same name won't work.  The resources should be defined locally.  There's a comment in the source code saying "In Tomcat 5.5+, we use context.xml to avoid configuration problems.", but no explanation as to what these configuration problems are.  If there really are configuration problems, then maybe the contexts should be defined in conf/Catalina/localhost/path.xml.

James Roper commented on CARGO-714:
-----------------------------------

It's actually the <Transaction> tag that isn't supported globally, changing it to use <Resource> for transactions works.

James Roper updated CARGO-714:
------------------------------

    Attachment: transaction.patch

Attached a patch that fixes the problem.  This doesn't solve the fact that everything is global when it shouldn't be, but it does make transactions work.
