Hi there,
i have a jsp which runs just fine under tomcat 5.5.9 but throws an exception in
tomcat 5.5.12 and 5.5.15.
Here is a part of the code:
----code snippet----
ByteArrayOutputStream baos = new ByteArrayOutputStream();
//creates a pdf out of the baos
pdfPrinterEB.createPDF(baos);
response.setContentType("application/pdf");
//set Header Information
response.setHeader("Content-disposition", "inline;
filename="+pdfPrinterEB.getFileName());
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma:", "no-cache");
response.setContentLength(baos.size());
try {
ServletOutputStream servletOut;
servletOut=response.getOutputStream();
baos. writeTo(servletOut);
servletOut.flush();
} catch (IOException ex) {
}
----codesnippet----
The following exception occurs:
----exception----
08.03.2006 12:20:51 org.apache.catalina.core.StandardWrapperValve invoke

----exception----
Like I said before, the code works for Tomcat 5.5.9, neither getOutputstream()
nor getWriter() are called at any place in the application.
