Can't deploy : No source code is available for type javax.servlet.http.HttpServlet

[Baptiste Lafontaine]

Hello,

I have a little projet that is composed of a single Servlet.

It's working fine on localhost, but when I want to deploy I get the following errors : 

   Validating newly compiled units

      Ignored 1 unit with compilation errors in first pass.

Compile with -strict or with -logLevel set to TRACE or DEBUG to see all errors.

   Finding entry point classes

      [ERROR] Errors in 'file:/C:/Users/magnetik/git/semola-rdf/org.magnetik/src/org/magnetik/semola/client/RDFServlet.java'

         [ERROR] Hint: Previous compiler errors may have made this type unavailable

         [ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly
