Re: Problems with in.valueOf() function in jbiHelper
Thanks Lars..
I have more question.
file i have scenrio like this
In my drools file i have to check some conditions and based upon this i
need to return the IN message contents to OUT message.
Generally we will be using jbi.answer(" ") to send response from drools
endpoint. But the problem is as it accepts only string content , i have to
convert the IN message into string explicitly and then send ti jbi.answer().
Is there any other way to this because converting a mesage into string is
taking more time.
I tries the following also. I just replicate the answer() method of
jbiHelper but i am getting the following error
java.lang.IllegalStateException: component is not owner when trying to set
error: java.lang.Exception: No rules have handled the exchange
But when i converet the In message into string and call answer() method its
works fine.
The only statement which is thre in the answer() method of jbiHelper but not
in my statement is update()
Is there any way to solve this.

Re: Problems with in.valueOf() function in jbiHelper
Posted by lhein <lh...@apache.org>.
Sachin,
I added new methods to the JbiHelper class now supporting Source objects as
content.
See:
http://svn.apache.org/viewvc/servicemix/smx3/trunk/deployables/serviceengines/servicemix-drools/src/main/java/org/apache/servicemix/drools/model/JbiHelper.java?view=markup
You can now call answer method with a Source parameter (for instance your
inMsg.getContent()).
But this change is only available in the trunk version. So if you want to
try it, you need to get the latest snapshot or build it on your own.
Regards
Lars
