NoClassDefFoundError PDFParser OSGi

Hi,

I'm new at TIKA and also on this mailing list.

I use the TIKA 0.6 bundle under eclipse to extract metadata from files and it works with all kind of files except PDFs. 
I get the error message below. 
The code was tested with several PDF's. Also, I tested the PDF's with an older program, which is working under TIKA 0.5. And there the PDFs can be read. 

Can anybody help me?

All regards
Stefan

PDFBox 0.8.0 uses commons-logging. It's declared as an optional
dependency in the Tika 0.6 bundle, but you'll need to have it in your
classpath (or OSGi environment) for the PDF parser to work.
