How to execute an I*E task from Java code.

[pmoothedath]

Hi all,

Has anybody got a small example of executing an I*E task (in folder <windhcill_home>/tasks/...) from a Java code. ? I use the following code which throws error.

String taskPath = "D:/ptc/Windchill_9.1/Windchill/tasks/searchOrg.xml";

WTProperties wtproperties = WTProperties.getLocalProperties();

String instance = wtproperties.getProperty("wt.federation.ie.VMName");

System.out.println("instance = " +instance);

Task task = new Task(taskPath);

task.addParam("instance", instance);

task.invoke();

The error I get is

java.lang.ClassNotFoundException: com.ptc.windchill.keystore.WTKeyStore

Try this.

WTProperties props = WTProperties.getLocalProperties();

Task myTask = new Task("ext/myTask.xml", props.getProperty("wt.federation.ie.VMName"));

myTask.setUsername(user.getName());

myTask.addParam("param1", "param1value");

emailTask.invoke();

It looks like your task is being called though from the stack trace above, so I'm guessing its a problem with the content of your task file itself.

Why did you do this?

String taskPath = "D:/ptc/Windchill_9.1/Windchill/tasks/searchOrg.xml";

I always use the IE servlet via the method server.

Are you running the separate Info*Engine server?

Thanks David.

Do you have any code samples of calling thru IE servlet ?

And my I*E server runs within the method servers. Do you know of any configurations to have it run externally.

Thanks

Rama,

Are you getting the same error as above?

I think this article goes along with what Dave mentioned in letting the I*E server/Adapter from the method server handle the task processing:
