JMS sender adapter : message type null is unknown, payload cannot be read

[Former Member]

Hello,

We are building a scenario Weblogic -> PI through a JMS adapter, but we are getting the following error in the adapter :

2009-09-29 12:09:58 Information New JMS message with JMS message ID ID:P<450046.1254218997063.0> received. The XI message ID for this message is e705a65f-3cf6-472a-3675-b04e9862ce45.

2009-09-29 12:09:58 Warning JMS message ID:P<450046.1254218997063.0>: message type null is unknown, payload cannot be read and will be empty!

2009-09-29 12:09:58 Warning JMS message ID:P<450046.1254218997063.0>: Payload empty or cannot be read.

2009-09-29 12:09:58 Information JMS Message was converted to XI message succesfully.

Despite the fact that the message is not readable, PI creates a message anyway but the payload is empty. It is the same issue as described in this thread :

But there have been no answer there.

We have read many notes but none are relevant, any ideas ????

Many thanks,

GL

Hallo,

Have you seen this note:

[Note 837501 - J2EE JMSAdapter: Empty payloads, unknown JMS message types|https://service.sap.com/sap/support/notes/837501]?

Seems it can be either message

a) does not contain any payload and/or

or

b) is not of type TextMessage or BytesMessage

Hello Jakub,

Thanks for your quick reply, indeed I have seen this note, but no idea on how to check what we have received. The guys from weblogic are sending an XML for sure, so the message is not empty, but no idea on how to check what is wrong in this file, it seems well formated...

Any idea ?

Many thanks,

GL
