Please help. Content type: Sending pdf content to the browser
Hi,
I have read several postings about sending a different content to the
browser. I am trying to generate a pdf using FDF in my action. I get the
content displayed as plain text. I tried many ways ( I had set the content
type both in Response and RunData objects in my action. Also tried to use
data.setContentType in the template. Nothing worked). The same code works
fine if I use that in a Servlet outside turbine.
I am using turbine 3.
Please help.
Thanks in advance.

It doesn't actually work in Turbine 3 .
All it output on the screen is the plain text of the FDF document(Adobe FDF
api).
Thanks for the reply.

This is how i send files to the browser.
All documents are stored in a table in MySql, in a blob field.
For pdf files the content_type is "application/pdf".
I use turbine 2.
_attach = (Attachments)(_trans.getAttachmentss().elementAt(0));
_contentType = _attach.getContenttype() + ";name=" + "\"" +
_attach.getFilename() + "\"";
data.getResponse().setContentType(_contentType);
data.getResponse().getOutputStream().write(_attach.getContent());
hope this can help you.
Greetings.

Enclosed is a class I wrote that extends Turbine's RawScreen to display pdf
files. If you can create your pdf stream as a ByteArrayOutputStream then
the following will work "as-is" for you. Simply extend this ADT and build
your pdf stream in a buildPDF method, returning a ByteArrayOutputStream.
Even if it doesn't work for you, maybe it will help.
Steve
public abstract class PdfScreen extends
org.apache.turbine.modules.screens.RawScreen
{
/**
* Set the content type to Pdf. (see RawScreen)
*
* @param data Turbine information.
* @return content type.
*/
public String getContentType(RunData data)
{
return "application/pdf";
};
/**
* Classes that implement this ADT must override this to build the pdf
file.
*
* @param data RunData
* @return ByteArrayOutputStream
* @exception Exception, any old exception.
*/
protected abstract ByteArrayOutputStream buildPdf (RunData data) throws
Exception;
/**
* Overrides & finalizes doOutput in RawScreen to serve the output stream
created in buildPDF.
*
* @param data RunData
* @exception Exception, any old generic exception.
*/
protected final void doOutput(RunData data) throws Exception
{
ByteArrayOutputStream baos = buildPdf(data);
if (baos != null)
{
HttpServletResponse response = data.getResponse();
//We have to set the size to workaround a bug in IE (see
com.lowagie iText FAQ)
data.getResponse().setContentLength(baos.size());
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
}
else
{
throw new Exception("output stream from buildPDF is null");
}
}
}
