JMS Receiver content conversion error

Hi All,

I have configured jms receiver channel with content conversion parameters. I have used multimapping concept. I have configured 4 communication channels to send messages to different queues based on conditions. One channel is getting success and remaining 3 are getting error. The error is...

Message processing failed. Cause:com.sap.aii.af.sdk.xi.adapter.trans.TransformException: Transformer Conversion3.0.5226 Error initializing Class: java.lang.Exception: java.lang.NumberFormatException: For input string: "4 "; nested exception   caused by: java.lang.Exception:java.lang.NumberFormatException: For input string: "4 "

Please suggest your ideas to solve this issue..

Thanks in advance.

Regards,

Ashok.
