Atom via XMLBeans

Got tired of futzing learning XSD etc so started on something potentially useful. First step, get Atom feeds working through xmlbeans. Success!

    public void testCreateFeedType()
        AuthorType author = AuthorType.Factory.newInstance();
        author.setName("Brian McCallister");

        FeedType feed = FeedType.Factory.newInstance();
        feed.setCopyright("copyright 2004 BMc");
        feed.setTitle("Test Feed");

        FeedDocument doc = FeedDocument.Factory.newInstance();


gives me

<feed version="0.3" xmlns="">
  <title>Test Feed</title>
    <name>Brian McCallister</name>
  <copyright>copyright 2004 BMc</copyright>

I'll take small victories =) Next step is persisting these things to xindice, and pulling em back out. Then Cocoon enters the picture and the real fun can begin. Oh fun day!

Along the way I learned that despite having someone who knows some shell scripting, BEA has pretty much standardized on Windows for development, I think:

[mccallister@kite ~/src/xml-xmlbeans/v1/bin]$  

and the scomp compiler shell script doesn't even actually work without some hacking =)

The most interesting bit is that I originally implemented an Atom object model by hand and added the xdoclet tags to generate the OJB and Torque metadata needed to persist atom elements back to a relational database. This was a lot of code. The atom XSD (unofficial one by Randy Morin) on the other hand compiled to all of the needed Java from about 109 lines of xsd.
