• Using Axis’s wsdl2java in a Maven Build

    When using Apache Axis, you often want to generate the service stub code from a WSDL file provided by the remote API developer. We recently ran in to this situation at Highwinds.

    What we wanted to do was keep the WSDL in source control, and use Maven to build the source from the WSDL at build time during the generate-sources lifecycle hook. This seemingly simple task ended up taking me some time to figure out – not because it was hard, but because there are so many bad implementations of Axis plugins for Maven out there, and Google has all of them in its sights.

    Finally, I found a really nice implementation by the Codehaus guys. Here’s the POM for those of you who might be interested. Enjoy!
