.PoolTcpEndpoint.process  Socket(PoolTcpEndpoint.java:527)at org.apache.tomcat.util.net.MasterSlaveWorkerThread  .run(MasterSlaveWorkerThread.java:112)at java.lang.Thread.run(Thread.java:619)   
My code for the generate and forward of the pdf follows here:
   quote:   public class MakePDF extends AbstractPdfView{
   @Override   protected void buildPdfDocument(Map model, Document document, PdfWriter writer, fromServletRequest request, fromServletResponse response) throws Exception {
   String linebreak = new String(quot;\nquot;);   Examination_data examination_data = null;   Patient_data patient_data = null;
   String filename;
   ByteArrayOutputStream baos = new ByteArrayOutputStream();
   patient_data = (Patient_data) model.get(quot;patient_dataquot;);   examination_data = (Examination_data) model.get(quot;examination_dataquot;);
   PdfWriter.getInstance(document, baos);
   response.setContentType(quot;application/pdfquot;);
   filename = (String) examination_data.getFilename();
   String split[] = filename.split(quot;\\.quot;);
   if (split.length == 1){   filename = filename + quot;.pdfquot;;   }   else if (split.length == 2){
   if (!split[1].equals(quot;pdfquot;)){   split[1] = quot;.pdfquot;;   filename = split[0] + split[1];   }
   }
   response.setHeader( quot;Content-dispositionquot;, quot;attachment; filename=quot; + filename + quot;quot;);
   document.open();;
   /**   * In das PDF Dokument einfuegen   */   // Name   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Name: quot;));   document.add(new Paragraph(patient_data.getName()));
   // Firstname   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Firstname: quot;));   document.add(new Paragraph(patient_data.getFirstname()));
   // Date of Birth   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Date of birth: quot;));   document.add(new Paragraph(quot;testquot;));
   // Gender   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Gender: quot;));   document.add(new Paragraph(patient_data.getGender()));
   // Bodysize   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Bodysize: quot;));   document.add(new Paragraph(patient_data.getBodysize()));
   // Weight   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Weight: quot;));   document.add(new Paragraph(patient_data.getWeight()));   document.add(new Paragraph(linebreak));
   // Indication   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Indication:quot;));   document.add(new Paragraph(linebreak));   document.add(new Paragraph(examination_data.getIndication()));
   document.add(new Paragraph(linebreak));   document.add(new Paragraph(linebreak));
   // Finding   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Finding:quot;));   document.add(new Paragraph(linebreak));   document.add(new Paragraph(examination_data.getFinding()));
   document.add(new Paragraph(linebreak));   document.add(new Paragraph(linebreak));
   // Comment   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Comment:quot;));   document.add(new Paragraph(linebreak));   document.add(new Paragraph(examination_data.getComment()));
   document.add(new Paragraph(linebreak));   document.add(new Paragraph(linebreak));
   //Diagnosis   document.add(new Paragraph(linebreak));   document.add(new Paragraph(quot;Diagnosis:quot;));   document.add(new Paragraph(linebreak));   document.add(new Paragraph(examination_data.getDiagnostics()));
   document.close();
   response.setContentLength(baos.size());
   ServletOutputStream out = response.getOutputStream();
   baos.writeTo(out);
   out.flush();
   }
   }
Does anybody have an advice or knows a workaround for this error?

Thanks

It's not obvious what the actual reason is. But since you already send the response to the client nothing else is allowed to do something like this anymore. The forward mentioned in the error message - however it is triggered - is quot;something like thisquot;. It might be an Acegi issue. Does it cause the forward for a security issue?

Is this application using JSF? If a Faces Request is being made which generates a Non-Faces Response, then you will need to skip the Faces Response by calling FacesContext.responseComplete().

Hi cmelger,

thanks for your post, it helps me a lot.

Thank you

Tim
