Sure, just use the dsjob command line program. I'm sure you know how to execute unix commands, so dsjob is no different.

There is a C-callable API (called DSAPI) documented in both the Server Job Developer's Guide and the Parallel Job Developer's Guide.

While there is no explicit Java API, or set of classes, I'm sure you could make use of the DSAPI from Java.

But it won't make your work easier. Instead of leveraging all the error handling and other idiot-proofing that "they" have invested into dsjob, you seek to re-invent the wheel (given that there's no Java API).

So I think your best solution is to make system calls to dsjob. I suggest the Runtime class exec() method. You can research this on the Web, for example here.

What is your intention?? Are you trying to use an applet to invoke dsjobs or are you trying to run multiple threads of your java application? Assuming you are able to invoke and run the datastage jobs from java, how are you planning to call the java program itself??

If it is from UNIX you can aswll write a shell script to call dsjob commands.

I think I posted code to do it using DsObjects. Do a search. That code is also posted in VB. This way you do not need dsjob loaded on all your clients. It maybe more difficult to code though.
