RBD - generating JAVA for CICS JVM server - OSGi bundles

  • 1.  RBD - generating JAVA for CICS JVM server - OSGi bundles

    Posted Thu November 13, 2014 08:09 AM

    Hello,

    is there a support in the RBD for generating java and creating java OSGi bundles for CICS JVM server ?  

    Any experience in this area, suggestions, tools that may help .... ?

    Regards,

    Nenad,

    I know you are also pursuing this through a PMR, but what type of EGL java application are you trying to deploy?   And are you trying to use the CICS Liberty support?

    Here is a link that gives you some info on using EGL under CICS Liberty and specifies the use of the CICS Explorer to help you build CICS Bundles.

    http://www-01.ibm.com/support/knowledgecenter/SSMQ79_9.1.0/com.ibm.egl.gg.doc/topics/gegl_core_cics_liberty.html?lang=en-us

    Note that one upcoming feature in the already announced 9.1.1 is support for JCICS from EGL Java to COBOL when running under CICS Liberty.

    Hello Mark,

     

    we are trying to create and deploy CICS JVM server appl. - i.e. CICS Bundles (OSGi). Basically those programs do the same things as existing cobol transactions - processing request, accessing data (DB2) , returning response …

    No JEE/WEB technologies like JSP, servlets etc. involved here … so I guess there's no point deploying such apps into Liberty profile ….

     

    Regards/Pozdrav,

    Nenad,

     

    Our only experience for the CICS JVM is in packaging web based applications.   Don't know if you can get standard CICS type transactions to run in one of them.  I know we do not do anything in Java Generation to target Java under CICS for these types of applications.

    Mark,

    guess that means that there are no plans from IBM side to support CICS JVM Server (OSGi framework) as a target runtime environment in RBD ?

    Nenad,

    At this time, we don't have any explicit plans to target the CICS JVM Server (OSGi framework) for all types of applications. 

    What is your requirement in terms of the type of application you want to run there?  3270 type, batch, ??

    We have done the work to support the CICS Liberty profile for EGL web applications (Web transactions, JSF, RUI based), which if I understand correctly get deployed as OSGI bundles.  See following EGL Blog article on this topic:

    Support for CICS Liberty and JCICS

    For batch type applications, if the CICS JVMServer/OSGI support supports any native type Java app, I would think there is a good chance that generated Java would work there as well since it really is not platform dependent even if though a "system" is specified.  These would NOT use JCICS type commands and we have not tested it.
