unable to figure out

Hi all,
In our project we are making use of EJB 2.1.
I know that a Stateless Session Bean has three files:
*) Component interface - Used to declare our business methods.
*) Home interface - Used to declare life cycle methods.
*) Implementation class - Consists of implementation of life cycle methods as well as the Business methods.

So when we invoke a business method using the Component interface reference object, the business method of the Implementation class will be called. MY DOUBT IS THAT - HOW IS THIS HAPPENING?? AS THE IMPLEMENTATION CLASS IS NOT IMPLEMENTING THE COMPONENT INTERFACE. !!!
I was told that the Container will look after all these things internally. But i want to know- how the container is performing this task??? Can anybody help me in this regard

Thanks in advance

debugging web application on weblogic from eclipse

hello vicky,
whenever you make some changes in your web application, just save the changes and just redeploy your web application in the web logic server. i think that restarting of the server is not reqiured, just redeploying the web application is enough...!!! just try it.... i m not completely sure...

what does deployment of a web application mean?

The process will depend upon the specific container being used. Which is it?

i am deploying my web application in web logic 8.1 server.
i know that different servers require different procedures of deployment. but the thing that i want to know is how is this deployment different from running the web application??? what does this deployment mean??

problem in compiling Action class?

i agree with what all you have told....

i tried compiling it from the classes folder as you told, but even then i m getting the same errors. The problem is that the compiler is not able to locate "NameForm.java". if i remove all the statements related to NameForm class in NameAction.java, then it is compiling successfully. one of my friend told that there might be problem with path and classpath!!! what you have to say about this.

Please provide some solution.
Thank you.
