If you replace
@RemoteServiceRelativePath("SignUpservlet")
with
@RemoteServiceRelativePath("../foofysignup/SignUpservlet")
the rpc request should work. This is not a good solutions but it works at least.
As Terrell pointed out you app is loading from /com.mpigeon.foofy.signup.SignUp/ but due to your rename-to attribute your app should be loaded from /foofysignup/. This may be caused by old files in you WebContent folder.
Could you post your SignUp.html?
Have you done a GWT Compile since adding <module rename-to='foofysignup'> to your gwt.xml?
From this error it appears that your app expects the servlets to be mapped under the default fully qualified module name : RequestURI=/com.mpigeon.foofy.signup.SignUp/SignUpservlet
加载中,请稍侯......
