One lets you write ESQL.
The other lets you write Java.

one can find Java developer easily and also they cost less .....but ESQL !! most of the developer dont know what is that and client have to pay more.

JCN is an enhancement of MB 6.0 . This introduces you to code in Java language which you can't do with ESQL easily.
Read about JCN in infocenter. You can find lot things.

| Java Compute node also comes in handy when u need to use predefined classes....With ESQL you need to rewrite the whole thing |

But coding in esql gives better perfomance than java in broker. So, I think it is better to use classic compute node when ever possible.

I can not agree with you.
There are functions and procedures in ESQL also.

Tree manipulation is a lot neater in ESQL, because that is what the language was designed for. Java is better at general purpose logic.
Throughput performance isn't wildly different in one versus the other - it depends what you are doing.
Both are important. Message Broker is trying to be unbiased about one technology over another; it's about providing choices. |
