Subject [jira] Commented: (SMXCOMP-638) NotSerializableException with JMSFlow when camel returns an exception.
Date Tue, 03 Nov 2009 11:33:52 GMT

    [ https://issues.apache.org/activemq/browse/SMXCOMP-638?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=55137#action_55137

Willem Jiang commented on SMXCOMP-638:
--------------------------------------

Hi Glovani,

I tried to apply your patch on the latest servicemix-camel component , and I found there some
issue of your latest solution after running some test.

1. If the exception has no message,  you will get the NPE when you trying to put exception
message into exchange.

2. If the camel processor throw the exception out , we will hit the NotSerializableException
if the exception have some trouble to serialize.

So my suggestion is wrapping the exception with a  JBI exception to avoid the  NotSerializableException,
and use the exception.toString() as the JBI exception message.

Any thought?

Willem

> In servicemix when a camel route handles an exception that is then returned to the NMR
it will attempt to return the exception object with the exchange. Using JMSFlow if the exception
object is not serializable, it will fail to be sent back with a NotSerializableException.
This is similar to SMXCOMP-18, but instead the problem here happens with the  CamelProviderEndpoint.
