Recieving error with a VMO Plugin that has a JMS stack built-in

[pwyzorski-wyzgu]

Hey,

I have an Orchestrator 4.0 plug-in with a JMS client stack that I am attempting to initialize from within a Orchestrator workflow. The class that supports the JMS stack is getting properly created, but I am recieving an error upon initialization. Error log is below. Can anyone on the Orchestrator team take a look at it?

regards,

~Patrick

Hi,

How do you have defined your scripting objects in VSO.xml? Do you use the "Singleton" pattern?

[pwyzorski-wyzgu]

I have no "singleton" scripting objects defined in my "vso.xml" file. Should I have? What the purpose of the "singleton" attribute anyways? The Developers Guide isn't exactly clear.

regards,

~Patrick

The purpose is to define some sort of Singleton object: you can compare the usage to a Java class with only Static members.

But your object is instanciated by vCO when you need it.

When exactly do you have the message error? Do you have some scripting execution? Or does it happen before any workflow start?

[pwyzorski-wyzgu]

Workflow has started, in fact I manually launch a vCO workflow that calls the plug-in Java class which initializes the JMS Client. Here is the reference the debug log:

"public void ppsb.stagebank.MessageClient.initializeMessageClient()"

It seems to get called as the JMS client code appears to be getting invoked. Here is the reference that has me believe that:

"org/apache/activemq/ActiveMQConnectionFactory (Workflow:Initialize SPT JMS / Initialize JMS Client (item0)#1)"

But later it errors and this message has me concerned:

"Received change on an object not registered in the factory !"

What does the above error message mean?

[pwyzorski-wyzgu]

I didn't copy my dependent jar files to the proper location "app-server/lib" directory in the Orchestrator environment. I had actually copied them to the "app-server/server/vmo/lib" directory. Copied all dependent jars to both directories and rebooted Orchestrator fixed things. My JMS Client is now happily processing messages.

regards,

~Patrick

Moving thread to the forum that is more appropriate. Please post plugin API & web service API related topics in the Orchetrator API forum.

Thanks,
