Xml message is a text message (but parsed). You can try to read the message as text, and parse it as XML in your process.

The question is that you won't be able to validate that message against a schema when received , you will to do it it in your process after read it.

This will require some sort of middleware as Appian is down and cannot react in any way.

Thanks for replying.

Kafka Tools plugin in Appian only supports text based messages. Messages that we are receiving are in XML.
Implementing a JMS queue, I believe will lead to the same problem as they still sit on Appian nodes and will be down during maintenance ?

Implement a process that reads messages from a JMS Queue or Kafka Topioc

Kafka Tools

When the server is under maintenance, no message will be read, (and the most important is that no message will be lost)...

Once the server is up and running , the messages will be read as expected.
