Transaction Manager

[seanx]

The default transaction manager is in-VM transaction manager.
I am just wondering if there is any transaction managers available. In particular, the kind of transaction managers which can 1) propagate transaction context across virtual machines, 2) do transactional logging.

Thanks

We provide a Tyrex integration for this purpose, until we have a few minutes;-) to enhance our own tx manager. There don't seem to be many people using this, and it may require a little tweaking to get it working with any particular jboss version.

Thank you, David, for the reply.

I realized that and was trying to confirm. Does anyone have a working configuration using Tyrex and would like to share the config?

thank you very much in advance.

I've finally been able to get the server to start with full Tyrex support, but unfortunately, distributed transactions still don't work. What I did was:

Get jboss nightly source and build.

In my out-of-the-box jboss-3.0.0 installation:
Edit jboss-service.xml to enable Tyrex, and disable the default transaction manager.
Downloaded tyrex-1.0.jar from tyrex.exolab.org, dropped it into server/<server name>/lib.
From my jboss source build, copy varia/output/classes/tyrex_patch.jar into server/<server name>/lib.

I think I also plopped xerces.jar in there as well.

Then things finally started without a hitch. Unfortunately, when I tried my distributed EJB call, instead of getting org.jboss.tm.TransactionImpl not serializable, I got tyrex.tm.impl.TransactionImpl not serializable. Doh!
