Subject [jira] [Commented] (CAMEL-4668) JpaConsumer - Should rollback if processing of an exchange failed
Date Sat, 12 Nov 2011 09:50:51 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-4668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13149027#comment-13149027
] 

Claus Ibsen commented on CAMEL-4668:
------------------------------------

Sending to JPA does *not* fail. So the 3 template code lines works fine.

Its the Camel route that fails. The JPA consumer is scheduled, so it will poll again later
(after 2sec). And it will keep failing due that hardcoded exception being thrown. But foo
and bar records will be fine, but as they are part of the same TX, they will also rollback.
So the foo and bar counter will keep incrementing.

> If a JPA consumer pickup X messages and then one of those messages fails to be processed
and throws an exception, then the JPA consumer should detect this and mark the TX as rollback.
> Currently there is a flaw which causes the JPA consumer to commit the batch.
