EJB sample for Websphere z/OS

[nox828]

Hi mainframer,

I'm looking for a practical tutorial (deploy and use), how EJBs work on IBM WebSphere running on z/OS. The limitation is, that everything of the deployment should be done within the wc3270 emulator, because the zeus mainframe is of the IBM System z University Program for Europe. The software components are all installed, e.g. websphere app server 6.1.

I read a lot on the IBM website, but couldn't find a clear and short howto.

Hello Nox,

I do not have experience in EJB with Websphere, because I work more on the batch-part.
For practical instructions I would take a look at some of the IBM Redbooks (this helped me very well on Java Batch).
One example would be http://www.redbooks.ibm.com/abstracts/sg245754.html

Why would you want to use a 3270 terminal for deployment?
I would try to find information about deployment from within the IDE Eclipse (for example ant-scripting, etc.).

For the IBM z University program (I took part myself 2011 in Germany) it would be much more motivating for students to see something "common" in context of the new big mainframe

Regards,

Oliver

Hi Oliver,

I tried to use the wc3270 terminal, because it's the test environment on our university's mainframe. There is no remote access for http or eclipse, therefore the terminal...

I browsed the reedbook several times and decided to set up my own dedicated WAS environment for doing a practical excercise. I was not able to find a example for terminal and also the output isn't that.

A few weeks ago I was at the IBM plant in Böblingen and they presented a lot nice common products. I think so too, the z University, needs an update, immediately :

Anyhow, Thanks a lot for your reply to this atypical question,

Brgds, Daniel

Hi Daniel,

you could try to access the university's mainframe through ftp via an Ant-Script. I tried this, but I'm not sure on what machine (University Tübingen I think) and this worked with Eclipse. For configuration I used the Redbooks about Java Standalone Applications (as I said, I'm more working on Java Batch).

Via ftp you can upload jcl, start jobs and get the job-output, so this would be everything you need. And the "cool" thing is: The students don't have to use the 3270-Terminal at all when programming Java.

I have a colleague that works with EJB software on mainframes (I think he is using Eclipse too).
I will try to get some information for you, but he is on a workshop until the end of this week. Hope to hear from him tomorrow or monday/tuesday.

Regards,

Oliver

Hi Daniel,

I am sorry to write that late, I simply forgot this post.
My colleagues did not use something out of a Redbook. They made their own Ant-Scripts, so I cannot help with something like a PDF or ebook.
