    <p>I have a propertiesbean which gives me SqlSessions. This bean is annotated with all this jazz @ the class level</p> <pre><code>@Singleton @LocalBean @Startup @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED) </code></pre> <p>i also have this</p> <pre><code>public SqlSessionFactory getSqlSessionFactory(ConnTypes connType) {...} </code></pre> <p>which returns the SqlSession you want.</p> <p>I have two databases. One is a mysql instance and the other one isn't (lets call it db2). </p> <p>When I run the project locally everything is fine. Both databases are accessed with no problem.</p> <p>When I run the project on our test server it starts to throw a Client Transaction aborted error. I've done a fair amount of research on this and it seems like people get these exceptions when there is a problem with a database query or some database access. The entire transaction is then marked as rollback and this exception is thrown (at least that's what i've read)</p> <p>It looks to me like it throws an XA-Resource error right before the first time it throws the client's transaction aborted error. I know that you can get those when your bean tries to access another session. I've seen this error before when running locally and trying to maintain connections to both databases in one method. </p> <p>Could it be that my singleton properties bean, which accesses both databases, gets into a weird transactional state trying to return a mysql session in one thread and a db2 session in the other?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
