NoClassDefFoundError Appache

[xkacicka]

Hi, im trying convert docx to pdf, but, when im calling WordprocessingMLPackage.load(File); it will crush and write:

java.lang.NoClassDefFoundError: org/apache/log4j/Logger
at org.docx4j.openpackaging.Base<clinit>(Base.java:38)

so, i know, that apache logger isnt in my docx4j jar file, but, is it real problem? or have i not correct version of docx4j? answer pls. Thakns

You need log4j on your path; it is referenced in almost every class.
