1.5 Shipped Examples

HydraExpress ships with several Web service and XML binding examples located in your <installdir>\tutorials directory. These examples are used for illustration in various chapters throughout the documentation. Most examples include already-implemented applications which you can use immediately to see how HydraExpress works.

Each example directory contains

• one or more schemas or WSDL files to be used for code generation

• sample implementations to easily run and test the example

• a HydraExpress project file example-project.xml to be used as an argument to the code generator

A HydraExpress project file is provided with each shipped Web service and XML binding example to ensure that the example runs correctly.

Each tutorial includes the XML Schema(s) or WSDL(s) to be provided to the code generator, in addition to any options recommended or required by the particular example. For instance, most example-project.xml files set whitespace=true, which results in more easily-read output.

Using the example-project.xml file as an argument to the Code Generator invokes the generator in exactly the same way as including each option separately on the command line.

For example, invoking the code generator with:

prompt>rwsfgen example-project.xml

where the example-project.xml file is this:

<rwsf-codegen-project>  
  <options>
    <option name='project-name' value='MyProject'/>
    <option name='whitespace' value='true'/>
  </options>
  <files>
    <inputSchema file='po.xsd'/>
  </files>
</rwsf-codegen-project>

is exactly the same as invoking the following:

prompt>rwsfgen -projectname MyProject -whitespace po.xsd

For the shipped examples, we recommend the use of the provided project files. For your own projects, you may choose to create customized project files to include various options, or you may manually enter options and files at the command prompt.
