Using CSClient with taskid

CSClient is a session object , created when user logs into TeamSite.

This interface has getCurrentUser(), getGroup(), getTask() etc

I can obtain CSClient object from CSFactory.

CSClient client = factory.getClient();

If I do client.getCurrentUser(), it should provide me the user name,
for client.getGroup(), it should get me the group to which user belongs,
for client.getTask(), it should get the task.

But in here I have to provide branch path to get CSBranch object OR task id to get CSTask. How do I obtain taskid that is not specified. Does it mean that when java class is invoked, taskid should be passed to it ?

Can I not obtain taskid, the way I could do in Perl module with $taskId = $cgi->{form}{task_id};

Is there a way to taskid in CSClient or any other class ?

OR do I need to get task id using this perl module only and then pass it to java class. Is that only way ?

Thanks

"in here" means where? Mechanisms to obtain various Objects of CSClient Type that you may need dedepend on your
operational context.

It seems that you are talking about external Task. If so, create (and set in the Model) a Class that implements CSURLExternalTask
Interface and upon transition, WF Engine will pass "ready to go" CSClient, CSExternalTask and Hashtable Parameters Type Objects
to your "execute" Method. Having Client and Task, you can find all you need that relates to this Client, Job and Task

Like Boris said/implied, it all depends on the execution context. Based on [thread=39903]your other thread[/thread], the perl script you're using as an external task wrapper should be receiving the task ID as its second parameter, which you can then pass as a cmd line arg to your java fork and then read it in as part of the String[] args to the main() method. The code you posted in the linked thread looks about right, so if you're having trouble with passing that parameter through, you'll have to be more specific about where it fails in the process.

I am trying the code just now. If any issues, I will post back.

Some clarification is as below.

By "in here" , I meant PDF manual. Signature of methods are as follows in manual.

CSBranch getBranch(CSVPath path, boolean validate)
CSGroup getGroup(java.lang.String name, boolean validate)
CSTask getTask(int id)

In a java class, how do I obtain taskid ?

If so, create (and set in the Model) a Class that implements CSURLExternalTask Interface

Can I use CSURLExternalTask for stand alone java classes invoked by wft external task OR is it available for use with WFM only ? If I can not use CSURLExternalTask with wft, then how do I get tasked and other parameters, which are available from CSClient ?

Can I use CSURLExternalTask [...]invoked by wft?
[...]How do I get tasked and other parameters?

No, you cannot use CSURLExternalTask interface in WFT. Yes, you can easily get all sort of Task/Job information from
within WFT's Perl Task, including Task owner information, Task details, attachments and the like. The way I see it,
you have exactly 3 Options:

1. Resources/Time allowing, re-build in WFM.
2. If you have to keep WFT, do it in Perl. Code fragment below illustrates how to start with this Option.
3. Continue this masochism of trying to re-create CSSDK Objects using System's WFT API and vise versa. You may even succeed, who knows...

*** Notes for Option 2.
Run perldoc on TeamSite::WFtask, pay attention to getThis-and-That() Methods. Note that from the Task you can get
Workflow Id (among other things) and if needed, instantiate an object of TeamSite::WFworkflow type to get Job information.

To instantiate an Object of TeamSite::WFtask Type you will need Task Id. WF Engine passes it. External Tasks and CGI Tasks
have different parameter passing mechanisms. It is passed as a parameter to External Task. For CGITask, it is posted. So...[php]use TeamSite::CGI_lite;
use TeamSite::WFtask;

#--- Within Extermal Task
my ($jobid, $taskid) = @[0..1];
my $task = Teamsite::WFtask->new($taskid);
if ($task->IsValid()) {
my $this = $task.getThis();
. . .
}

#--- Within CGI Task
my $cgi = new TeamSite::CGI_lite;
$cgi->parse_data();
my $taskid = $cgi->{form}{task_id};
my $task = TeamSite::WFtask->new($taskid);
if ($task->IsValid()) {
my $that = $task.getThat();
. . .
}[/php]

(It's so nice to have DevNet back ;-))

No, you cannot use CSURLExternalTask interface in WFT.

I'm not sure of the validity of the above statement. A CSURLExternalTask is just an ExternalTask with a URL for the command (and some specific task variables like "ClassName") so you should be able to invoke a Java class that uses the CSURLExternalTask interface and which would automatically be provided the CSClient object, CSTask object, and the hash of other parameters (if any; I've never tried to go through that hash)

Unless I'm misreading the response and the question was to be able to directly use the CSUrlExternalTask interface within the WFT code itself rather than as part of a external task - in which case - the response already given (by Boris) makes sense.
