Threads aren't very difficult at all ... I use them all the time.

so i would like to know more about this tcp/ip
solution how does it work, does it have the same issue
as data queue, or it can handle multiple request
can you provide some pointers or place where i can get
some information with code sample
i m pretty comfortable with both the languages.

Well, the issue with handling multiple requests has nothing to do with the way the request is sent from the RPG to the Java ... if you want to handle multiple requests at one time you'll need to use threads ... or multiple processes.

TCP/IP is less straight forward than using a data queue ... but, possibly, more efficient. I haven't really researched the difference much.

One of the advantages of the TCP/IP technique is that abandoned transactions are easy to manage. With a data queue (assuming you use a keyed data queue), you really need to keep track of what transactions are active and which are not. With TCP/IP if the transaction is abandoned, the connection is lost and you handle it programatically.
