Preprocessor class not executing when invoking WF from java with iwmodelc

G'day

Running on TS 7.3.2 on Win2k8...

Trying to instantiate a simple submit WF from a Java class using iwmodelc. That part works, i get a jobID back, but the WF is basically an empty shell at this point.

What I want to do is basically auto-submit a file (non-dcr xml) when saved in CCPro. File is saved/edited using custom jsp/servlet...

I thought using a preprocessor would be the proper way to attach the file i want to submit etc... but it seems the preprocessor is not firing when job is instantiated via iwmodelc... not seeing my log output from the preprocessor...if i manually submit, i do see log output confirming preprocessor is executing.

also seeing a ton of com.interwoven.cssdk.access.CSInvalidRoleException: Unknown Hopi error(no such role) errors in my log...but i think this might be related to something else... :-)

Any tips or advice is greatly appreciated.

I'm fairly sure preprocessors don't execute with iwmodelc, as you described.

The way I've built server-launched workflows is to create an external task right at the start, which executes something like /bin/true (or something like "dir" on windows). Basically, it just dies there and doesn't transition.

Then, in your code which calls iwmodelc (to which you give the flag to start the workflow), you'll have a workflow that stops on the first task. You can attach files to this task, and then transition it from your parent script to kick off the actual functionality.

Note: do NOT use an actual DummyTask for this. You can't transition a dummy task in code, nor can you attach files to it.

Thanks... I'll try that approach.

Ok.. this "works"... in that i can tap into my external task from my java class, attach files etc.. and invoke the submit transition to send it to my submit task.

But im seeing the following in the iwtrace.log

[Mon Jan 26 14:46:07 2015] Error: CreateProcess failure user=SYSTEM; argcount=4; errCode=2; cmd=dir c:\
[Mon Jan 26 14:46:07 2015] Execution of command dir failed (Error: 2000004) for user: SYSTEM

Does this have anything to do with the parameters WF engine is passing down? (hence the argcount=4) ?

Unrelated. This means that you have a task owned by SYSTEM and JBoss wasn't able to impersonate that user. If said task is PERL and you're on Win2k8, that's fairly common ootb. I'd suggest converting the task to Java, but you can also disable task impersonation in the iw.cfg (all non-Java external tasks would run as SYSTEM) or you can attempt to fix it -- probably by setting the owner to "NT AUTHORITY\SYSTEM" or "HOSTNAME\SYSTEM", whichever makes your server happy. (Or you can go messing around in the windows security policies)
