Hi!
I have a following problem. I have a stamping application to place a stamp in the PDF document. While everything in Windows works great, when I upload it to a machine running Tomcat (to stamp the documents generated on-the-fly), I get an error... Here it is:
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Servlet execution threw

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
com.sfs.filter.CacheControlFilter.doFilter(CacheControlFilter.java:47)
The bolded line points to this function:
public
boolean newFile(OutputStream outputStream, float height, float width, String
author, String title, String subject) {
coord=new PDFCoordinates(width, height);
document = new Document();
try {
writer
= PdfWriter.getInstance(document, outputStream);
document.addAuthor(author);
document.addSubject(subject);
document.addTitle(title);
pageWidth
= width;
pageHeight
= height;
document.open();
pdfContentByte
= writer.getDirectContent();
pdfTemplate
= pdfContentByte.createTemplate(pageWidth, pageHeight);
g2D
= pdfTemplate.createGraphics(pageWidth, pageHeight);
} catch (DocumentException e) {
System.out.println(e.getMessage());
return
false;
}
return true;
}
Is it possible that while running on tomcat the iText has a problem creatingGraphics and returning an object Graphics2D... or is the problem two lines before, getting the DirectContent? Either way is there a workaround, how would i go about fixing this....
Thanks!
