Enterprise beans that use container-managed transaction demarcation must not use any transaction management methods that interfere with the container’s transaction demarcation boundaries. Examples of such methods are the <tt>commit</tt>, <tt>setAutoCommit</tt>, and <tt>rollback. </tt>If you require control over the transaction demarcation, you must use application-managed transaction demarcation.</em>"</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The idea is that I want to use manually commit, rollback... but I don't know how. Is the information above the right direction for what I need? Should I use application managed transactions instead of container managed transactions which is default? How can I do this? Any documentation on this would help too. Thank you.</p></div>
