how to set the lifecycle state of wtpart using API

[aashishramchand]

I am trying load a wtpart into windchill through API's and i would like to know how to set the lifecycle state of the part to a specific state.

The LifeCycleHelper class is used for this. eg

String myState = "PROTOTYPE";

WTPart myPart = <already defined>;

LifeCycleHelper.service.setLifeCycleState((LifeCycleManaged) myPart, State.toState(myState));

[aashishramchand]

I tried that and getting this error.

Exception in thread "main" (wt.fc.fcResource/0) wt.util.WTException: The operation: "setLifeCycleState" failed.
Nested exception is: wt.util.WTRemoteException: Unable to invoke remote method; nested exception is:

This is an issue with your setup. You apparently are not running this on Windchill itself eg: jsp page, workflow, etc.

See this article for running code from a java client:

I executed the code from the windchill shell and im getting the same error as before "Illegal arguments Exception".

Hi @aashishramchand,

Can you try following and let me know if that helps!

package ext;

public class TestLifeCycleState implements wt.method.RemoteAccess {

	public static void main(String[] args) throws java.rmi.RemoteException, java.lang.reflect.InvocationTargetException {
		wt.method.RemoteMethodServer rms = wt.method.RemoteMethodServer.getDefault();
		rms.invoke("setState", "ext.TestLifeCycleState", null, null, null);

	}
	
	public static void setState ()
	{
		//Your code
		//String myState = "PROTOTYPE";
		//WTPart myPart = <already defined>;
		//LifeCycleHelper.service.setLifeCycleState((LifeCycleManaged) myPart, State.toState(myState));
	}

}

Regards,

Bhushan

Still getting the error.

[BhushanNehe]

@aashishramchand Can you share MS logs and also the code in Text format. Also, can you elaborate on your requirement are you trying to create a new object with non-initial state or just trying to set state for an existing already persisted object?

Regards,

Bhushan

[aashishramchand]

@BhushanNehe yes, I am trying to create a new object with non-initial lifecycle state

public class Tester implements RemoteAccess {

	public static void main(String[] args) {

		RemoteMethodServer rms = RemoteMethodServer.getDefault();
		rms.setUserName("username");
		rms.setPassword("password");

		try {
			rms.invoke("setState", Tester.class.getName(), null, null, null);
		} catch (RemoteException | InvocationTargetException e) {
			e.printStackTrace();
		}
	}

	public static void setState() throws WTException, WTPropertyVetoException {
		String name = "TestPart1"; // Name
		String number = "00000055"; // Number
		String lifeCycleName = "Basic"; // Lifecycle name
		String container_path = "container path";
		String folder_path = "/Default/Design"; // Folder path
		String PPAPRevision = "20";

		WTPart newPart = WTPart.newWTPart();

		newPart.setName(name);
		newPart.setNumber(number);

		WTContainerRef containerRef = WTContainerHelper.service.getByPath(container_path);
		newPart.setContainerReference(containerRef);

		Folder folder = FolderHelper.service.getFolder(folder_path, containerRef);
		FolderHelper.assignLocation(newPart, folder);

		LifeCycleTemplate lct = LifeCycleHelper.service.getLifeCycleTemplate(lifeCycleName,
				newPart.getContainerReference());

		newPart = (WTPart) LifeCycleHelper.setLifeCycle(newPart, lct);

		String myState = "RELEASED";
		LifeCycleHelper.service.setLifeCycleState((wt.lifecycle.LifeCycleManaged) newPart, State.toState(myState));

		newPart = (WTPart) wt.fc.PersistenceHelper.manager.store(newPart);

	}

}

here are the MS logs:

Hey @RandyJones ,your solution is right , but we have to first store the new part which we created and the change its life cycle state.
