Hi All,

I use Oracle Database 10g Express Edition + jboss-4.0.4.GA-Patch1
and i try to use XA distributed transaction, but i have strange error for me:

21:36:44,753 WARN [TransactionImpl] XAException: tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=stoyan/14, BranchQual=, localId=14] errorCode=XAER_RMERR

I see support JBoss page:
http://wiki.jboss.org/wiki/Wiki.jsp?page=IHaveProblemsWithOracleXA

I don't understand wery well:
Configuring Oracle Database for XA Support You can configure Oracle database to support XA resources.
Because when i unstall my db i cann't found any about XA support.I think by default
oracle after 9.3 ver support XA transactions

Some ideas? please

my xxx-ds.xml is: (and i put class12.jar in jboss/server/default/lib from my oracle client)
<?xml version="1.0" encoding="UTF-8"?>

<xa-datasource>

Thanks in advance!
