How can I add new properties in JMS MDB Listener Service?
My application requires to add some additional properties in JMS MDB Listener service headers. Can that be done? I did one POC by adding the required properties in the header dropdown by privately editing the Data Transform pzInitServiceJMSParameterName. I tried to update deployment descriptor as I have added this new property in JMS header. I got the following message :
Failed to update ejb-jar.xml, generated MDB descriptor already exists in ejb-jar-xml.
Use generated fragments to manually update ejb-jar.xml.

I restarted the listener and tried to process some inbound message. I got the following error message :

What version of PEAG used? We don't have JMS MDB Listener service instead we have JMS MDB Listener and Service JMS can you please clearly mention where you are trying to add these properties.
Thanks,

Hi,
The following are the valid headers for JMS/MDB service rule
destination
deliverymode
messageid
correlationid
priority
timestamp
expiration
replyto
redelivered
type
This is handling in java code, as of my understanding except these values if you pass any other value you will get the same error as "Invalid header name: <<header name>>".

Hi,
These are values only allowed in header, there is validation in code to check header values.
