[opencms-dev] Developed an XML Indexer for Lucene but getting error

[M Butcher]

Alex,

I can't tell, from the stack trace, what is going on. Judging from where 
the exception is located, it looks like a problem with content defs... 
but that doesn't make sense....

When you finish it, please do send it to Stephan and I. It sounds like a 
very useful addition to the existing indexing tools.
