Pleaase help me!!
Hello,
firstly, please excuse my english because i'm French and my english is not very fluent...
I'm working on a electronic signature software developped with java and i need do convert document into PDF.
My IDE is Netbeans 7.1.2 with JDK6.
Here is my problem, when i run the code I get this error :
run:
log4j:WARN No appenders could be found for logger (com.*.*.gui.MainForm).
log4j:WARN Please initialize the log4j system properly.

Exception in thread "Thread-8" java.lang.NoClassDefFoundError: Could not initialize class com.jacob.com.ComThread
at idainfront.pdfcreator4j.PdfCreatorApi.(PdfCreatorApi.java:50)

at com.*.*.util.Timeout$TimeoutThread.run(Timeout.java:15)
at java.lang.Thread.run(Thread.java:662)
The moment where I use PDF Creator API 's function:
public PdfCreatorApi() { ComThread.InitMTA(true); mPdfCreator = new ActiveXComponent("PDFCreator.clsPDFCreator"); mEventHandler = new EventHandler(this); mDispatcher = new DispatchEvents(mPdfCreator, mEventHandler); } ```
I Think there is a problem with initMTA() function from the ComThread class because the error says : "Could not initialize...."
the comThread class look like this...
package com.jacob.com;/**
* Represents a COM level thread This is an abstract class because all the
* methods are static and no instances are ever created.
