Embedding JSPWiki 2.6

[Ethan Larson]

Hi all,

I'm trying to use JSPWiki within a Grails application to add wiki markup 
to content within my site.  I tried following the "Embedding JSP Wiki" 
instructions (http://jspwiki.org/wiki/EmbeddingJSPWiki) and looking at 
the javadocs (http://www.ecyrd.com/~jalkanen/JSPWiki/javadoc/) but 
neither is up to date with JSPWiki 2.6.

Basically, I just want to turn some wiki markup into html and possibly 
run my own plugins at a later date.  Here's what I've got so far:

           Properties props = new Properties();
       WikiEngine engine = new WikiEngine(props);

       WikiContext context = new WikiContext(engine, new 
WikiPage(engine, ""));
       JSPWikiMarkupParser parser = new JSPWikiMarkupParser(context, 
new StringReader("This is a test string"));

       System.out.println(parser.parse().toString());

But when I run it, I get this message when creating the WikiEngine:

Exception in thread "main" com.ecyrd.jspwiki.WikiException: Failed to 
instantiate class com.ecyrd.jspwiki.PageManager
   at com.ecyrd.jspwiki.util.ClassUtil.getMappedObject(ClassUtil.java:312)
   at com.ecyrd.jspwiki.util.ClassUtil.getMappedObject(ClassUtil.java:228)
   at com.ecyrd.jspwiki.WikiEngine.initialize(WikiEngine.java:509)
   at com.ecyrd.jspwiki.WikiEngine.<init>(WikiEngine.java:359)

I'd appreciate any help.  If I can get this working, I may turn it in to 
a Grails plugin and release it to the wider community.

Thanks and happy new year,
Ethan
