iText ClassNotFound Exception

I'm using iText library to work with Acrobat Forms. The servlet compiled without any errors. I imported the external jar files of iText. After compiling, i packaged and prepared an executable .war file (Main.war) and pasted it in the deploy folder of jboss. However, on executing, i get a ClassNotFoundException Error.

Here's the stack trace

    java.lang.ClassNotFoundException: com.itextpdf.text.DocumentException from BaseClassLoader@955d1c{VFSClassLoaderPolicy@13ed0e{name=vfszip:/E:/jboss-5.0.1.GA/server/default/deploy/Main.war/ domain=Clas

And here's my servlet code -

import com.itextpd开发者_StackOverflow中文版f.text.DocumentException;

import com.itextpdf.text.pdf.FdfReader;
import com.itextpdf.text.pdf.PdfReader;

import java.net.*;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Main extends HttpServlet {
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
    {
      response.setContentType("application/pdf");
      try{
      FdfReader FDF = new FdfReader(request.getInputStream());
      System.out.println("*************Recieved inputStream***********");
      InputStream is = request.getInputStream();
      PdfReader reader = new PdfReader(is, null);
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
      PdfStamper stamper = new PdfStamper(reader, baos);
      AcroFields fields = stamper.getAcroFields();
      fields.setFields(FDF);
      stamper.setFormFlattening(true);
      stamper.close();
      OutputStream os = response.getOutputStream();
      baos.writeTo(os);
      os.flush();
      }
      catch (DocumentException DE)
      {
          throw new IOException(DE.getMessage());

      }
    }

   public void doPost(HttpServletRequest request,HttpServletResponse response)
  throws ServletException, IOException {
 doGet(request, response);
}

}

Can anyone tell me what's the problem????? Its urgent please..

Looks like a DocumentException would be thrown, but the corresponding class can not be found by JBoss.

• Are you sure that the iText .jar gets packaged with your webapp? Maybe have a look at the .WAR file you're deploying and check if the iText library is in there...
• If not (or you don't want to) make sure to put it in the JBoss' lib folder. in /jboss-as/lib/ or /jboss-as/server/default/lib/.

Edit: Your JAR should end up having a structure that looks about like this

.
|-- index.html
|-- META-INF
|   `-- MANIFEST.MF
|   
`-- WEB-INF
    |-- classes
    |   `-- <your code is here>
    |
    `-- lib
        `-- <here are your packaged .jar files>

[Mind, this is simplified and does not show all the files...]
