JMS: modulus operator in message selector

Question

I want to load balance JMS messages using message selectors.

A message has a property "EntitiyIX".

The selectors shall be like:

"EntitiyIX Modulus 2 == 0" ==> route to queue A
"EntitiyIX Modulus 2 != 0" ==> route to queue B

What's the operator to calculated the modulus in a JMS message selector?

Thanks, Alex

Answer 1

Assuming that the property is an integer, then I believe you could do

• (EntityIX / 2) = ((EntityIX+1) / 2) -> route to A
• (EntityIX / 2) != ((EntityIX+1) / 2) -> route to B
