You can put a serialized Java object into the bitstream that is the data portion of an MQ message. A simple way of doing this is to use JMS and an JMSObjectMessage.
Java Objects are very very very very very unportable.
Please don't do this.
Please write your data as data, not as objects to your MQ messages.

Convert the objects into data as suggested, and put the data with the API?

I just said that JMS made it simpler, I didn't say it was required.
Do you understand what a serialized Java Object is?
Do you understand how to write that to a bitstream?
Do you understand how to write anything to an MQ Message?
Again.
It is a very very very very bad idea to do this.
The only thing that will be able to read and unserialize this object is another object in the same JVM or another Java program, running on a compatible JVM level, that has the full necessary set of Java classes on the classpath, to fully unserialize this object.
Even if all you are doing is sending messages to yourself, it is much better to pass information as data than as objects when using MQ.
