How to get variable at workflow using URLexternal Task

Hi,

I have one small issue with the workflow.

I have one URLexternal Task which is calling java class.Predecessor to this task there is one CGI Task which is returning list of variables.

How can I fetch those variables into my java class?

Every Help is appreciable!!!

Is the CGITask setting task variables or job variables?
If job variables, then you should be able to do something like:

...
public void execute(CSClient client, CSExternalTask task, ...) {
    CSWorkflow job = task.getWorkflow();
    String varval = job.getVariable("varname");
    ...
}

If it is a task variable, then you have to create the job object and from there get a list of task objects, iterate through them to find the task with the name of your CGITask, and then from that task object, retrieve the variable(s) you want.

Thanks for the help, we are using something like:



public void execute(CSClient client, CSExternalTask currentTask, ......) throws CSException {


        String defaultTransition = Task.getTransitions()[0];

        CSWorkflow job = Task.getWorkflow();
        String TaskName = Task.getVariable(KEY_TARGET_TASK_NAME);
        //CSTask targetTask = getTaskByName(job, TaskName);
}

Is this the correct way to get the variable???

You have problems in the above code - or at least as far as what you've shown - because you have a parameter called currentTask and yet you seem to be using a variable called Task which does not appear to be defined.
That aside, if KEY_TARGET_TASK_NAME is a String that contains the same value as the name of a task-level variable that exists on the task referenced by Task - then yes, you should be able to retrieve the value of that variable like that.

If the variable is attached to a different task - then you have to get that task object first and then use it to get the value of the task variable you're looking for.

If the variable is attached to the job - you should be able to get it off of the job object you appear to have created above.

Hi Ghoti,

Thanks, I updated the currentTask to Task. Yes KEY_TARGET_TASK_NAME is a string in which we are passing the Task Name from where we are getting the variables. I dont understand the term "task-level variable"
Should we define the variable name instead of Task Name to get the variables?
The requirement is that we need to get all the variables from the CGI Task to the java class and use them for further processing.

If you don't understand the term "task-level variable" then you need to spend time reading the manuals and/or getting some training.

However - I'll try to provide you a quick primer here:

The code you originally posted along with your description of what you were trying to do was unclear with respect to whether the variables you are trying to access are at the job-level, the current task's level, or some other task's level - as such it is difficult to figure out where your code is wrong.Hopefully the above "primer" will help you figure it out for yourself from here.

You should note that job variables and workflow variables are the same. Those variable will be the same throughout the workflow unless your program sets them to something different. Task variables are specific to that task.

In order to get all the variables for a task, once you get the task, then use the task getVariables() method. You should also check for nulls on those objects too.
