here's a (stripped) example I use to generate print files within java code:
<tc:button id="printButton"
label="Print"
immediate="true"
transition="false"
action=""/>
public void printAction() {
String pathname = System.getProperty("java.io.tmpdir");
String filename = "test.pdf";
File pdfFile = new File(pathname, filename);
try {
PrintStream out = new PrintStream(pdfFile);
// Write the PDF content
out.println(...);
out.close();
sendFile(pathname, filename, "application/pdf");
} catch (IOException x) {
LOG.error("Can't create PDF file", x);
}
}

Hi Helmut, As per ur code, u give the location of a PDF doc on the server. Which when referred then that would be downloaded. But what if a pdf doc is generated within a javacode, say with Jasper Reports. How can i pass that pdf doc generated in runtime to the jsp page and display that ?
