First, make sure that your environment is set up as described in Chapter 2, Setup in the HydraExpress User Guide.

Run rwsfgen. The HydraExpress code generator requires a project name and at least one file argument that specifies either a WSDL file or an XML Schema. Multiple file names may also be specified.

The general command line format for the generator is:

for both a specified WDSL and an XML Schema. In addition, various generation options are available.

By default, rwsfgen generates code into a project directory based on the provided project name, in which it creates subdirectories to contain the generated files. Generated files include server-side and client-side code if a WSDL file was passed as the file type , data type classes for an XML Schema, sample C++ applications that use the generated code, makefiles, MSVC project files (for Windows platforms), and documentation.

The generator also outputs a HydraExpress project file named projectname.xml (as identified with the argument -projectname) that contains all project elements for this particular project. This file may be used as a future sole argument to the code generator if you wish to regenerate code with the same options, like so:
