Need advice how to run Axis2/Rampart client from Webshere

Hello,

I need to be able to make web service calls using WS-Security from the application that runs on Websphere. Are there any instructions how to do that?
My prototype standalone client sets up the ConfigurationContext as follows

ConfigurationContext ctx = ConfigurationContextFactory.createConfigurationContextFromFileSystem("c:/stage/axis2-1.6.2/repository", null);

How can it be done in the web application environment where the application is packaged in .ear file?

TIA,

-a
