How to deploy a java server method as a BOF module ?

Hi All,

we are trying to find a way to deploy a java server method as a BOF module. The reason : We could not replace the workflow method jar file simply by stopping the Java method server. It seems in Documentum 6.5 the Jar file is locked by some processes (from content server) other than the Java method server. In previous versions this problem was not there.

So to be able to deploy the java method server without having to bring down the content server we are looking to deploy the java method as a BOF module.

Looked up on google and bluefishgroup.com. But have not been able to find any working trick to do this. The suggested method is as below:

<<<

Steps to deploy BOF

1.         In Composer, create a new Module Artifact and select "Standard Module".

2.         In the module code, the class should implement the IDfModule and IDfMethod interface instead of the IDmMethod interface as follows:

import com.documentum.fc.client.IDfModule;

import com.documentum.fc.clientIDfMethod;

public class MyModule extends DfSingeDocbaseModule implements IDfMethod

{

    // module code

}

3.         In the dm_method object in the repository, enter the module name in the method verb parameter.  Note: This should not be the fully qualified class name but rather the name of the module.  Module-names can be successfully loaded by the method server as long as they implement IDfMethod.

>>>

When I did follow these steps and tried to use the module in Process Builder for a test activity, it gave me error " Error while retrieving the the module Mymodule"

I looked up the dmc_module object in the repository and the "Implementation method" field was blank for my module and it was set to "Java" for other modules which I could select.

Hi,

Its been a while since your post, but for what its worth - I managed to get the process you describe (and referring to http://donr7n.wordpress.com/2008/10/20/methods-as-bof-modules/) working in D6.5 SP1.  I've not come across any official documentation on this (extremely useful, especially in a distributed environment) feature yet, but presumably it is supported.

I'm not aware of an attribute called "Implementation Method" on the dmc_module type, but there is one on dm_method called 'method_type'. This should be set to java.

There doesnt appear to be much more to it.  As you say, dm_method.method_verb should equal dmc_module.object_name and dmc_module.primary_class points to the fully qualified java method.

In the code the class should implement com.documentum.fc.methodserver.IDfMethod and com.documentum.fc.client.IDfModule (which is also reflected in the dmc_module.a_interfaces attribute)

I used Documentum composer to create & install the method - I'm sure someone from EMC will comment if there's anything else going on here.

Cheers,

Keith
