Running Commands in Java

iw_store

Hi Experts,

With perl I know how to run TeamSite commands like iwpublish.exe.

Is there any method or way to run TeamSite commands in Java apart from Runtime.getRuntime().exec() ?

Thanks.

Any specific method of class in any CSSDK API document ? If on your top of mind.

publishEdition().

Interface is CSBranch.

Thank you much!

As Mav pointed out, forking a process is almost always going to be the wrong answer, because almost anything that you might have done before with a CLT, you can do through CSSDK. However, if you do run into some scenario where you need to invoke an external process, the documentation you need is here:

My Requirement is to write a java class for workflow InProcessor or PreProcessor, in that class I need to get the files attached to workflow, which I am able to do.

Now my JOB is to check whether those files are already attached to another workflow or task apart from present workflow.

If yes, I need to show a error message on instantiation screen or I need to set a job/workflow variable.

There is a CLT which I found for this iwgetfilejobs.exe, with which I can easily achieve my functionality with Runtime.getRuntime().exec(command).

How can I do same with Workflow java classes?

I found one method with CSFile (getRelatedTaskIds()), now my question would be how to convert/cast WFM file to CS file ?

I tried couple of ways for casting, no success .. My comfort level with Java is also creating problems

Coming from primarily a Perl comfort zone, I can understand this - and although I believe this has been posted several times - the basic code is something like this:
public void execute(CSClient client, CSExternalTask task, Hashtable hash) throws CSException {
...
CSAreaRelativePath[] flist = task.getFiles();
for (CSAreaRelativePath relPath : flist) {
String path = task.getArea().getVPath().toString() + "/" + relPath.toString();
CSSimpleFile csfile = (CSSimpleFile)client.getFile(new CSVPath(path));
...
}
There are various places where exceptions could be thrown / caught in the above code segment - it's up to you if you want to catch them or just let them percolate up "naturally".

The issue is that when you create a class for the Pre or Post Processor in a workflow model, you are given a WFMWorkflow instance, with no hooks into the CS framework. There is a lot less you can do with the WFM classes than the CS classes. It's a royal pain in the a$$.

Ah - point taken, I wasn't thinking about pre-/post-processors -- fortunately I haven't had to deal with any of them yet; I do all my processing within the workflow proper as opposed to the instantiation process.

I just happened to have had to deal with it recently, and if you can do everything you need to do within the WFM classes, it's great. But if not, you pretty much need to add tasks to the workflow to handle your business.

Don't get me started on Global Variables and the fact they are not editable within the WFM classes in Pre/Post Processor code. Grrrrrr
