Example/Steps for IDfLifecycleUserPostProcessing Module

Documentum 6.7 SP1 P09

I've been all over the EMC documentation, this forum, and PowerLink and I've yet to find a single up-to-date, complete and working example or instrutions for how to implement a post processing lifecycle module. I've got a ton of experience with TBO and SBOs but I don't have much (if any) experience with a standard module for a lifecycle post procedure and apparently it isn't as straightforward as you might think.

A few questions:

1. Does it require a specific naming scheme?

2. I have implemented IDfModule, and IDfLifecycleUserPostProcessing in my class, is there anything else?

3. Does it have to be installed to the global registry?

I can't seem to get it to deploy to the application server and when I promote to the state where it should be invoked it is as if there is no post processing module set, it is completely ignored. No debugging output in the logs, no anything.

No naming conventions.

Create class, implement IDfModule, and IDfLifecycleUserPostProcessing
Write your logic in the void userPostProcessing method
Package your class in the jar file
Open a Documentum Composer (preferably version 6.7 as the 6.5 is buggy)
Create a jar definition artifact with your jar in it
Cerate a Module artifact and set it's type to Lifecycle
Select your jar in the Implementation Jar section then select your class
Create (or import) a Lifecycle artifact and select your module in the PostChange tab for your Lifecycle stage(s)

The log entries can be found in the ServerApps.log in the Java Method Server as the Lifecycle java code is executed within the DmMethods app. Just make sure your log4j.properties is properly configured

Hope this helps

I think it may answer a few questions, if the information is still valid. Bluefish group is mostly all outdated information. Still helpful though. Thanks.

Thank you, this is great and exactly what I'm looking for but I have a couple of follow up questions:

1. There is no Lifecycle module type but only SBO, TBO, Standard Module

2. Should it be deployed to global repository or can it be deployed to the docbase in which the lifecycle will be used.

Except for question #1 above, this is exactly the process I have already followed. I selected Standard Module for that step.

I assumed it should be installed to the same docbase in which the lifecycle will be used and on a hunch I just typed "Lifecycle" into the type box in composer and reinstalled it. Everything works now. Thanks. This really should be documented by EMC somewhere.

Try putting "Lifecycle" into the Type field by hand.

Vadim, I do this steps:

Create class, implement IDfModule, and IDfLifecycleUserPostProcessing
Write your logic in the void userPostProcessing method
Package your class in the jar file
Open a Documentum Composer (preferably version 6.7 as the 6.5 is buggy)
Create a jar definition artifact with your jar in it
Cerate a Module artifact and set it's type to Lifecycle
Select your jar in the Implementation Jar section then select your class
Create (or import) a Lifecycle artifact and select your module in the PostChange tab for your Lifecycle stage(s)

and get in ServerApps.log next record:
