Re: defined startup class in websphere
anike...@gmail.com
I have a class WSServerStartup which implements CustomService. It has initialize(java.util.Properties configProperties) and shutdown() methods. where should I mentioned this class to execute at startup.
This class set parameters and loads data in XML files for processing.
Thanx

I have just migrated from weblogic to websohere 6. I have a class which get executed at startup. In webslogic I just need to modify the "startweblogic.cmd" file to execute the class. Now in websphere where should I specify the startup class. It is presentin the console option or do i need to specify in any of the cmd file.
Please help me in this.
Thanx
Ken Hygh
You define it as a custom service on the server.

Take a look at the custom service restrictions:
anike...@gmail.com
i have gone through the help page. i have configuredcustomservice but when i checked the logs I found following exception while starting the server. I have mentioned exact classpath (conatining all JARs, ZIP and class files). I also included the jar file which contains the customservice class. still its giving the exception...

loaded on server startup.
I was using the startup class in weblogic before, but I changed it like
I mentioned before to avoid the server dependency. It worked for me.
Ken Hygh
The fact that there's no package info in front of the missing class name
makes me wonder how you've configured this.

I put the startup class in Websphere\AppServer\classes folder and it started working. Now there is not classnotfoundexception appearing on startup but now there is new exception mentioned below. I searched on net and found that it is related to JDK version compatibility issue. Is It?? or there is any other reason for this???

Websphere configuration is not as simple as other servers.......Please help in this.
Ken Hygh
You may now have this class in two different classloaders. Make sure it
only exists once.
BTW, putting things into WebSphere\AppServer\classes is not recommended.

I have put my jar file into websphere\appserver\class folder. but when i remove the jar file from there it gives me ClassNotFoundException though I mentioned the jar file path into classpath field of custom service configuration. Whenere should I specify the jar file path??
Thanx for the reply....

Where is com/cedera/server/workflow/OrderStateMachine.class? What
compiler did you use to create it?
I'm thinking that you may have a
WSServerStartup.initialize(OrderStateMachine x) method?? if so, this is
the wrong signature for a CustomService
Ken
anike...@gmail.com
I had compiled my application with sun JDK 1.4, and its giving error to OrderStateMachine calss only other classes are running with no exception (mentioned in the startup class before calling OrderStateMachine). OrderStateMachine calss is present in the jar file only.
And I am using WSServerStartup.initialize(java.util.Properties configProperties) signature only......I have configured the custom service class according to the specification.........I have tried with different classpaths but its just stuck their......
Please help in this
Ken Hygh
Try compiling your classes with the JDK inside WAS. If that doesn't take
care of the problem, then I'm out of ideas I'd suggest you open a PMR
with IBM.
