I’m using a vendor API to obtain a JDBC connection to the application’s database.

I’m using a vendor API to obtain a JDBC connection to the application’s database. The API works when running in the application server or when running in a stand-alone mode. I want to run a series of SQL statements in a single transaction. I’m fine with them occurring in the context of the JTA transaction if it exists. However, if it doesn’t then I need to use the JDBC transaction demarcation methods. (Calling these methods on a JDBC connection that is participating in a JTA transaction causes a SQLException.)

So I need to be able to determine whether the Connection came from the JTA enabled DataSource or if it’s just a straight JDBC connection.

Is there a straight forward way to make this determination?

Thanks!

  1. Even if it’s straight JDBC, you can have a JTA transaction enabled. Checking the autoCommit flag will NOT help in this regard. You can be in a transaction, distributed or otherwise, with autoCommit set to false. autoCommit set to true would tell you you’re not in a distributed transaction but a value of false just means you won’t auto-commit… it could be in any kind of transaction.

    I think you’re going to have to call UserTransaction.getStatus() and verify that it is not equal to Status.NoTransaction(). This would tell you if you’re in a JTA transaction.
