iText ClassNotFound Exception - jboss

Question

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.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.AcroFields;
import com.itextpdf.text.pdf.FdfReader;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.PdfStamper;
import java.io.*;
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..

Answer 1

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...]
