RE: [JBoss-user] Informix XA and JBOSS 3.0.4
I've been able to get the XA drivers up and working under version 2.21JC3 of the IBM/Informix JDBC drivers and with Larry's help. I had to write a custom authentication module in order to be able to use the ODBC authentication setup (to simplify installation) as opposed to the users.properties file, and I had to modify Larry's wrapper to fix some other Informix problems (I couldn't get the SQLH_TYPE and SQLH_FILE parameters to work). But it is logging in and accessing the database. I didn't know about Larry's DB-locks problem, though.

RE: [JBoss-user] Informix XA and JBOSS 3.0.4
I gave up on the XA drivers and moved to the non-xa drivers. It appears that JBOSS tries to set the autocommit flag on a manage connection which generates an exception within JBOSS. Under JBOSS 3.0.4 I haven't found anyway to set the autocommit to false for the database at startup via the informix-service.xml (NON-XA). Any ideas Larry?

Re: [JBoss-user] Informix XA and JBOSS 3.0.4
I jumped through a lot of hoops to get Informix XA working on JBoss, including modifying the JBoss TransactionManager, and wrapping Informix's XA drivers. In the end, everything worked except for one recurring (and very annoying) problem: the database periodically extablished a lock on some data that it would not let go without a DB restart. None of the informix tools would release the lock. I whipped together some Java XA code that was able to fix some of the problems, but every now and then a DB restart was necessary. In the end, we ended up rolling back to the non-XA drivers. I have sent the wrapped drivers to several folks on this alias that asked about them. I think David Jenks and Jules Gosnell also asked about them at one point, but I never got them out. I have attached them here for the world to see/use/fix.
