Using WD APIs in Java Programming

Question

Hi,
     First let me explain my scenario:
          I have to get the <b>attachments in a PDF document</b>, using a <b>java program</b>. I am using Java perspective of NWDS. I am using the APIs
->IWDPDFDocumentHandler
->IWDPDFDocumentAccessibleContext
->IWDPDFDocument
->IWDPDFDocumentAttachment
in my program.
When I run my java program, I am getting the <b>java.lang.NoClassDefFoundError</b>.  Can you please, give me a solution for this problem?
Note :  I have added the necessary JAR files to the project.
Thanks,
Prabhakar.

Hi Sumit,
   Here is the result which I got in the console,
java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/services/exceptions/WDRuntimeException
     at PDFAttachment.readAttachmentFromPDF(PDFAttachment.java:241)
     at PDFAttachmentMain.main(PDFAttachmentMain.java:21)
Exception in thread "main"
Note :
PDFAttachment
- Class
readAttachmentFromPDF
- method
The code is,
String PDFDocName = "podetailswithAttachment.pdf";
                    //wdComponentAPI.getMessageManager().reportSuccess("Outside try FileName :"+PDFDocName );
                    try
                         //wdComponentAPI.getMessageManager().reportSuccess("Inside try FileName :"+PDFDocName );
                         FileInputStream fileInpStrm = new FileInputStream("C:\"+PDFDocName);
                         FileOutputStream fileOutStrm;// = new FileOutputStream()
                         ByteArrayOutputStream bo = new ByteArrayOutputStream();
                         int c;
                         while ((c = fileInpStrm.read()) > -1)
                              bo.write(c);
                         byte[] pdfSource = bo.toByteArray();
// Line :240     
                         IWDPDFDocumentHandler pdfdocHandler =WDPDFDocumentFactory.getDocumentHandler();
                         IWDPDFDocumentAccessibleContext pdfdocaccContext = pdfdocHandler.getDocumentAccessibleContext();
                         pdfdocaccContext.setPDF(bo);
                         IWDPDFDocument pdfDocument = pdfdocaccContext.execute();
                         IWDPDFDocumentAttachment[] pdfatt =   pdfDocument.getAllAttachments();
                         //wdComponentAPI.getMessageManager().reportSuccess("Length of the attachments: "+pdfatt.length);
                         //pdfdocaccContext.setPDF();
                    catch(Exception e)
                         //wdComponentAPI.getMessageManager().reportSuccess(""+e);
                         System.out.println(""+e);
Thanks,
Prabhakar.
