2003.11.21 - Microsoft SQLServer 2000 & AutoCommit

I had problems with MSSQL and automatic transactions, the solution I have found:
Use manual transaction!
Set auto-commit=false and control yourself the commit and rollback, closing all resources that you've used, including the Connection, preventing dead-lock in database and saving pooled connections. If you'll execute a single query, do the same, manual transaction.

2003.11.19 - AppFuse 0.9 with Microsoft SQLServer 2000

I (D33nar) am having trouble running Appfuse 0.9 as well as struts resume. After successfully compiling and building Appfuse, I can start the application on tomcat and get it running, logon with tomcat/tomcat. The problem arises whenever I try modifying data, the JDBC connection performing the update never finishes and all subsequent JDBC connections are blocked by the update connection. I tried using Microsoft and weblogic drivers for JDBC, but face the same problem.. I have spent significant time and am continuing to debug the problem, but would like to hear from anyone out there who has got Appfuse or struts-resume running on SQLServer.

UPDATE: I have traced the problem to JDBC auto-commit. I put a trace on the SQL sent to the server. A transaction is begun, but never committed, sometimes the driver/pool rolls it back with something like

IF @@TRANCOUNT>0 ROLLBACK TRAN BEGIN TRAN

I am not sure if it is

• the driver implementation (unlikely as I tried 3 different ones bea, ms and inet)
• something do the connection pool used
• transaction semantics in the hibernate
• or the appfuse code

I also found that everthing works fine with auto-commit=true, which is not a solution
