Generating a pdf, and sending it to user with using HttpServletResponse(headers)

Welcome all.
I'm trying to create a PDF to send to user, without saving the file on my server first.
I'm using Hibernate + struts2. My samples code: CreatePDF.java (Class for generate pdf) Method BuildPdf():

ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
    document = new Document();
    PdfWriter.getInstance(document,baos);
    document.open();
    buildPage(document, snippet, snippetContent);
    document.close();
    response.setContentType("application/pdf");
    response.setContentLength(baos.size());
    response.setHeader("Content-Disposition", "attachment;filename=document.pdf");
    ServletOutputStream out = response.getOutputStream();
    baos.writeTo(out);
    out.flush();
    response.flushBuffer();
} catch (Exception e) {
    Log4jUtil.debug(logger, "Can not buid pdf-file", e);
}

My sample action: method index():

pdf = new CreatePDF();
pdf.buildPdf(snippet, snippetContent);
return SUCCESS;

Can you check my code please for search error? Could there be errors.... Please help me. Need ideas, or example code to solve my task.

First, Hibernate is fully irrelevant here. Struts2 is relevant, but you are not using it, you are using plain (low level) servlet API. That should probably work, but if your webapp is built around Struts2, that's not the recommended way. You should instead use the Stream result
