I have a GWT application and wanna to test load and functionality using a tool like jmeter.
I am not sure jmeter is right tool for GWT. Can anybody direct me to proper tool or can tell me how to do it with jmeter?

I want to test login functionality: I have two text box 'User name' and 'Password' on login screen and want to test how many users can log in simultaneously, how much time a round trip to server it takes. Don't know how jmeter can get 'user name' and 'password' and can submit it to validate against DB for GWT application?

Thanks in advance.
