[FIXED] .NoClassDefFoundError when trying to use pdfBox

Issue

when I try to use one of the PDFBox examples for extracting images, in the run time,it gives me the following exception:

   Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
    at org.apache.pdfbox.pdfparser.BaseParser.<clinit>(BaseParser.java:68)

    ... 6 more

here is the part of the code that exception occurs, at the last two lines:

         String pdfFile = "pdf file path";
         File pdf=new  File(pdfFile);
         PDDocument document = null;
         document = PDDocument.loadNonSeq(pdf, null, password);
         document = PDDocument.load( pdfFile );

Solution

Add commons-logging-1.1.1.jar or jcl-over-slf4j-1.7.6.jar in your lib directory.
