Re: [JBoss-user] Could not enlist in transaction on entering meta-aware object

[David W. <dav...@do...>]

Igor, thanks for your help.  My code has many places where a SLSB puts=20
data into a DB, all with Transaction set as Required.

My app is basically like this (sorry for the ASCII art):

   HttpServletRequest
          |
          V
     HttpServlet
     - Look up and start UserTransaction
     - Translate and hand-off call to SLSB
          |
          V
Stateless SessionBean (TX=3DRequired)
- Delegates work to Application processors
          |
          V
Application processors
- Some might do JDBC via DataSource; - Some might use CMP
     |                                          |
     |                                          |
     V                                          V
Custom JDBC                  CMP EntityBeans (TX=3DRequired)

          V
     HttpServlet (Flow returns)
     - If no errors, commit UserTransaction
     - If errors, rollback UserTransaction


The JDBC work delegated to the application processors uses the same=20
JNDI-looked-up DataSource as the CMP Entity Beans are configured to use.=20
  We also have a custom login module that uses the same JNDI looked up=20
DataSource.

I will create a small test case as you mentioned.  I just thought that=20
describing how my app is set up might spark some thoughts from you or=20
others though while I'm doing that.

I've used earlier version of JBoss (2.4.x) that do all of the above=20
fine.  Of course, that was with Oracle 8i + classes12.zip instead of 9i=20
+ ojdbc14.jar, and using jdk 1.3.1 instead of jdk 1.4.1.

Thanks again,
David
