RequestFactory ValidationTool works on Linux but not on Windows

[Aldo Neto]

Hi,

I'm migrating my project to GWT 2.4 (I was using GWT v2.3) and when running the ValidationTool I'm getting an error, but that error is only displayed on Windows. When I run the same project on Linux, I get no error.

The output message is below.

I checked the ContratoUsuarioRequest class and I could not find anything different from other request classes.

Thanks,

Aldo

error: Could not load domain mapping for context ContratoUsuarioRequest.

Check that both the shared interfaces and server domain types are on the classpath.

Which version of Java (Oracle vs. OpenJDK, 6 vs. 7, etc.) are you using on both OSes?

Are they exactly the same?

Are you sure you're running exactly the same command? (same classpath, etc.)

[Aldo Neto]

I'm using Java 1.6 on both, but Oracle on Windows and OpenJDK on Linux.

The command is the same and the classpath should not be the problem, as I have other requests in the same directory as this one (the ContratoUsuarioRequest) and they present no errors.

Thanks

Hi,

I'm still facing this problem, so does anyone know how to fix this problem? Any suggestions?

Tks

[Aldo Neto]

The problem persists. I updated my java version from 6 to 7 (still Sun) and now I can get it to work on command line but not on eclipse. 

When running manually, I get the following warning:

warning: Supported source version 'RELEASE_6' from annotation processor 'com.google.web.bindery.requestfactory.apt.RfValidator' less than -source '1.7'

1 warning

But when I try to clean the eclipse project, I get the same error flag on my pom.xml.

The thing is that I don`t know where is the output file when running it on eclipse. Any ideas?

Thanks
