"java.sql.SQLException : Not in a transaction" when using CM

[nico1as]

Hi All,

every 10 min, my application get datas from a database and copy them in my main database.
For this, I use 2 CMPs with 2 xa-datasources.

But sometime, when I use the finder to get datas from the first database, I get this exception :
java.sql.SQLException : Not in a transaction

It's not a blocking error but I'm curious to know what does it mean ?
Maybe, there's a problem in my application configuration ?

I use JBOSS 3.2.4RC1 with oracle 8.1.7.4.

Thank you for your help.

Nicolas.

Have you tried using the Oracle specific
valid-connection-checker-class-name
rather than the
check-valid-connection-sql

[nico1as]

No, I didn't try it.

But after following your advise, it seems to be ok now.

Thanks you for your help.
