Good morning list,
A question about struts2 + PDF. Struts2 + itext5.x.
In action class:
==========================================
HttpServletResponse res = ServletActionContext.getResponse();
res.setContentType("application/pdf");
Document document = new Document();
PdfWriter.getInstance(document,
res.getOutputStream());
document.open();
...
document.close();
Always got the following errors:
====================================
ERROR tags.BaseSimpleTag.doEndTag:? - ERROR: getOutputStream() has
already been called for this response
org.apache.catalina.core.ApplicationDispatcher invoke
SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.IllegalStateException: getOutputStream() has already been
called for this response
Is there a way to fix it and is there any good online doc about how
struts2 + itext pdf file generation?
Also, how do you setup the default PDF file name?
Thanks a lot!
Emi
