Can someone tell what are the different ways that I can connect to CICS from java.
I know of the following
1) JAVA- > MQ --> MQ-CICS Bridge-->CICS Adapter->CICS transaction
2) Java-> CICS Transaction Gateway-->CICS Transaction
what are the other ways of communication to CICS from a Java app running inside Websphere App Server ? |

You can use the CTG:

Also, you can go "directly" into CICS (ie, have your CICS programs do the MQGET/PUTS )

I think amita09 mentioned both of those options already...
I don't know of any other options, other than the bad one of writing your own version of the CTG.

I was thinking and woundering if on z/OS one could use a 'USS Crontab' to get to MQ/CICS by way of using the MQSeries JMS feature.
i.e... use JMS to connect to a queue-manager that in return is connected to a kicks region. Sounds like it might work.

... With WebSphere Message Broker and CICS/TS 3.1 you can open comm-area from inside the broker directly to CICS without the CTG or putting a msg on a queue. Of couse you need WebSphere ESB (a.k.a JMS feature). and you can do it all with J2EE. Fun stuff.

Why would you think that JMS would not involve putting a message on a queue?

I think he is alluding to the ESB and the CICS Transaction Gateway resource adapter....
Put directly CICS on the ESB....
See my other post for what all comprises the ESB

I think I was aware of that... 
I think it still invovles putting a message on a queue, though. Even if it is not an actual WebSphere MQ queue, but merely a logical destination in the ESB.

With WebSphere Message Broker (an advanced ESB) and the new version of CICS TS 3.1... From inside WebSphere via an adaptor you can start CICS transactions by opening a commarea.... A MQSeries queue is not needed in this senario. You no longer need to put a message on a queue to start a CICS transaction...
Hey, have fun doing whatever it is you do.
