Websphere and iBatis Configuration

[Tom Henricksen]

We are setting up our application to use Websphere's JDBC connection.
When we setup this in Websphere in version 5.1 we needed to add the
commitRequired=true to get it to work.

<transactionManager type="JDBC" commitRequired="true">
 <dataSource type="JNDI">
   <property name="DataSource" value="${DBSOURCE}"/>
 </dataSource>
</transactionManager>

Although in our Websphere 6.1 server we didn't have to add this.
Would it be a good idea to use this?
Do most people using Websphere use this?

Thanks in Advance,
Tom
