Lifecycle in D2

Hi,

I am trying to ID2LifecycleServices to implement a lifecycle functionality for an existing dfc policy solution. The solution also has workflow and autoactivities frequently promote and change state of documents inside workflow. I am going through the d2 and d2fs apis. and also cam across D2WorkflowLicecycle apis. I am confused. What could be the best way/api to use here and also the Id2LifecycleServices has methods with parameters

changeState(Context context, java.lang.String docId, java.lang.String targetState, java.lang.String event, java.lang.String operation, java.util.List<Attribute> parameters)

What are these different parameters. A sample code using these could be easy to understand.

Did you check out this post already?

It's the same code only for a D2 workflow; a D2 lifecycle can be called almost the same way with that changeState method you mention..

Yes Antal, i did check this post...

Thanks a lot it helped me get the lifecycle working, Just that i includeda class implementing ID2LifeCycleServices interface and then used the changerequest method of it in my workflow method code. My question here was about another class which i might be missing correct name of here D2WorkflowLifecycle. Came across it sometimes, does this class hold capabilities of working with workflows and lifeccyle altogether?

I am talking about D2WFLifeCycleMethod(), this class

What I think you should do is calling that ID2LifeCycleServices.

You call the changeState method and do a promote to a target state.

In that target state you configure in D2 Config to start a workflow (this is one of the lifecycle-actions)

As this can be configured there is no need call a ID2WorkflowServices (what is not availabe) or a call to D2WorkflowLifecycle (what is not an interface to connect to!)

Hope this helps you on your way.

Yes, i was able to use the ID2LifecycleService interface method changeState and got it to a target state. But there is a parameter Attribute in this. and i tried to use createAttribute and modify the custom document object attributes on which lifecycle is running but the sample throws me a soap error...the attribute param here is param for lifecycle obj or attributes of custom document on which LC is running?? Any help here pls...

I dived i bit deeper; That ID2LifecycleService is used when you want to create a D2Plugin; this way you can override the standard D2Lifecycle change state method. What you want is a direct call to D2FS and trigger a lifecycle promote

Try this Java method; we do this from our custom dm_module that is called by a dm_method

That ChangeStateRequest call can be found in http://<HOST>:<PORT/D2/ws/d2fs.wsdl

This should help you on your way...

objectId -> r_object_id of the applied object

targetState -> The name you configured in D2-Config for your state

operation -> promote | demote

private void callD2FSLifecycle(String objectId, IDfSession session, String targetState, String operation, String dctmUsername, String dctmTicket, String dctmRepositoryId, String dctmRepositoryName) throws DfException {

Context context = new Context();

context.setLogin(dctmUsername);

context.setPassword(dctmTicket);

Repository repos = new Repository();

repos.setId(dctmRepositoryId);

repos.setRepositoryName(dctmRepositoryName);

context.setRepository(repos);

ChangeStateRequest stateRequest = new ChangeStateRequest();

stateRequest.setId(objectId);

stateRequest.setContext(context);

stateRequest.setTargetState(targetState);

stateRequest.setOperation(operation);

final ChangeStateResponse stateresponse = (ChangeStateResponse) new D2FSWebServiceSupport()

.getWebServiceTemplate().marshalSendAndReceive(stateRequest);

}

Thanks Antal,

I was able to commit changes using both the apis also now it is clear for me the usage of both the methods. But even if i use ID2LifecycleServices interface to do promote states in workflow methods and serves the purpose, will it be better idea to use D2FS operation?? Thanks your thougts made it easier.

Both apis are via D2FS as far as I know.

ID2LifecycleService -> Override the standard D2 lifecycle service via D2Plugin that is called by an action done via D2FS (For example a call from ChangeStateRequest)

ChangeStateRequest -> Call a direct D2 lifecycle promote/demote from any DFC-code. This should also trigger the ID2LifecycleService (If you made it custom with a plugin; this will also be triggered)

Hopefully this makes it all clear.

Best regards,

Hi,

As a requirement, a document moves through different state with different activities in workflow it is attached to. There is D2WFLifecycle Method attached to each autoactivity and the lifecycle state change configuration takes care of updation of few attributes. In one such autoactivity, i'm trying to call a custom method and updating few attributes based on some logic(reason why i cannot do this through D2 Config.) After updation of these properties, method tries to change state of the document to next state, something like this:

lifecycleObj.changeState(contextObj, obj.getObjectId().getId(), "NextState", "Checkin", "promote", attributesToBeChanged);

But this doesn't work, the dump doesn't show change in a_status. Do I need to use:

public LifeCycleResult apply(Context arg0, String arg1, String arg2,

String arg3) ...the apply method, if so, is anyone aware about the parameters to be passed.
