Hi everyone, I have an app that generates reports in PDF format and streams
them to the client browser from a servlet. The report viewer page has an <embed
tag which calls the servlet, which then streams the PDF to the client.
This works beautifully in my JDEV/OC4J environment. When I deploy to JBOSS
3.2.4 (JVM 1.4.2_03) is stops working and gives me one of these errors:
File does not start with ?%PDF-? (most frequently)
The file is damaged and could not be repaired
File connection timed out
Any ideas would be greatly appreciated!!!
I have tried all of the following suggestions gleaned from your and other
forums:
Web.xml:
<servlet>
| <servlet-name>eStarReport.pdf</servlet-name>
| <servlet-class>com.estar.servlet.eStarImageServlet</servlet-class>
| </servlet>
| <servlet-mapping>
| <servlet-name>eStarReport.pdf</servlet-name>
| <url-pattern>/com.estar.servlet.eStarImageServlet</url-pattern>
| </servlet-mapping>
|
| <mime-mapping>
| <extension>pdf</extension>
| <mime-type>application/pdf</mime-type>
| </mime-mapping>
Code that streams the pdf :
arResponse.setContentType("application/pdf");
| arResponse.setHeader( "Content-disposition", "inline;
filename=eStarReport.pdf");
| arResponse.setHeader("Cache-Control", "no-cache");
| also tried: arResponse.setHeader( "Cache-Control", "max-age=30");
| also tried :arResponse.setHeader( "Cache-Control", "must-revalidate");
| ByteArrayOutputStream ltestStream = new ByteArrayOutputStream();
| this.outputReportPDF(ltestStream);
| arResponse.setContentLength(ltestStream.toByteArray().length);
| OutputStream lResponseStream = arResponse.getOutputStream();
| ltestStream.writeTo(lResponseStream);
| if (! arResponse.isCommitted()) arResponse.flushBuffer();
Tag on Report Viewer page:
<EMBED ID="Report_Object"
SRC="eStarReport.pdf;JSESSIONID=2B14CDC409E1B5FC5096B9E0A209009E?REPORT_ID=26526028"
