working with PDF files please

1. download the two missing libraries  from:

2. Put them to directory src/plugin/parse-pdf/lib
3. follow the instructions in file src/plugin/parse-pdf/plugin.xml
4. Rebuild nutch.

This distribution includes cryptographic software.  The country in which you 
currently reside may have restrictions on the import, possession, use, and/or 
re-export to another country, of encryption software.  BEFORE using any encryption 
software, please check your country's laws, regulations and policies concerning the
import, possession, or use, and re-export of encryption software, to see if this is 
permitted.  See <> for more information. 

The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has 
classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which

distribution makes it eligible for export under the License Exception ENC Technology

Section 740.13) for both object code and source code.

Apache Nutch uses the PDFBox API in its parse-pdf plugin for extracting textual content
