Launching from Eclipses causes errors in browser

I've got a strange situation; when I run a Flex app from Eclipse (i.e. click run as web app), my remote calls always hang.

In Firefox, they re开发者_开发百科turn as failed.

But when I open up a browser and browse to my .html file in the bin-debug folder, the remote calls work.

Why is that?

Thanks for any helpful tips!

p.s. I'm accessing a websphere server and authentication is required but a Java developer hardcoded his ID in.

One thing to check:

Do you have a breakpoint set in your code somewhere? Eclipse may be waiting for you to interact with it so the program execution can continue. On my Win7 machine, when the debugger takes over, eclipse often does not take over focus; so I have to manually minimize IE.

My problem was solved today and the issue was getting through to the IBM websphere server; the authentication was still in place and the java developers had to create a cloned environment where authentication was not required. Thank you everyone for their helpful answers.
