PDF reports from webapplication [message #49174]

Hi,

I built BIRT into my web application and it work generating HTML
reports. But I need PDF format, so I changed to OUTPUT_FORMAT_PDF but I
don't get any output, just a blank screen.
In Eclipse preview, the PDF works.

What's going wrong?

Here's the log:

Do you at least see a PDF file?

Can you log a bugzilla entry with the report attached? If your report uses
special data sources, can you make sure to reproduce it with a
self-contained data source?

The strange thing is that from the delivered ViewerServlet it works, but
I can't find any real difference to my code.
So I think it's not a BIRT problem.

Juergen,
you think you can show me how you got the html to display on the
webapp. My jsp script runs and generates and output file but there is
nothing on the screen. If you can point me in the right direction I would
greatly appreciate it. Thanks

Hi Adam,

This is more or less code I copied from the ViewerServlet. It works with HTML but not with PDF:

<<<< cut here

/**
* Process incoming HTTP GET requests
*
* @param request Object that encapsulates the request to the servlet
* @param response Object that encapsulates the response from the servlet
*/
public void doGet(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, java.io.IOException {
PTIdentListData listData=null;

/*** Test BIRT **/
System.err.println("Start BIRT test...");
try {
EngineConfig config=new EngineConfig();
config.setEngineHome(getServletContext( ).getRealPath("")+"/birtreport");
ReportEngine engine=new ReportEngine(config);

IReportRunnable report = engine.openReportDesign(getServletContext( ).getRealPath("/birtreport/jsloc.rptdesign"));

// Render options:
IRenderOption option = new HTMLRenderOption( );
ServletOutputStream servletOutputStream = response.getOutputStream( );
option.setOutputStream( servletOutputStream );
option.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_PDF);

// Run task
IRunAndRenderTask runTask = engine.createRunAndRenderTask( report );
HashMap params=new HashMap();
params.put("paramPartId",new Integer(1730)); // part ID of part to display
runTask.setParameterValues(params);
runTask.setRenderOption( option );

/** PDF:
response.setContentType( "application/pdf" );
*/

/** HTML: **/
// Render context
response.setContentType( "text/html;charset=utf-8" );
response.setHeader( "cache-control", "no-cache" );
HTMLRenderContext renderContext = new HTMLRenderContext( );
renderContext.setImageDirectory(getServletContext( ).getRealPath( "/birtreport/images" ));
renderContext.setBaseImageURL( request.getContextPath( ) + "/birtreport/images");
runTask.setContext( renderContext );
/*** **/
runTask.run( );
servletOutputStream.flush();
servletOutputStream.close();
return;
}
catch(Throwable e) {
System.err.println("BIRT Exception: "+e.toString());
e.printStackTrace();
}

System.err.println("End BIRT test...");
<<<< cut here

Thanks for the code to help out. I am using java and I looked at all the
manuels and it looks like i am doing it right. The only thing is, is that
nothing displays on the webapp. I know that it runs since i have been
debuggin it and it is running all the way. Here is my code. If you can
see anything wrong please let me know. Remember i am running it from a
jsp script.

EngineConfig conf = new EngineConfig();
String home = "C:\\WWW\\Tomcat 5.5\\webapps\\birt\\WEB-INF";
conf.setEngineHome(home);

HTMLEmitterConfig hc = new HTMLEmitterConfig();
HTMLCompleteImageHandler imageHandler = new HTMLCompleteImageHandler();
hc.setImageHandler(imageHandler);
conf.setEmitterConfiguration(HTMLRenderOption.OUTPUT_FORMAT_ HTML, hc);

ReportEngine rengine = new ReportEngine(null);
String fileName = "C:\\WWW\\Tomcat
5.5\\webapps\\birt\\reports\\report1.rptdesign";
IReportRunnable report = null;
try{
report = rengine.openReportDesign(fileName);
} catch (EngineException e){
out.println(e);
rengine.destroy();
return;
}

IRunAndRenderTask task = rengine.createRunAndRenderTask(report);
HTMLRenderOption option = new HTMLRenderOption();
option.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_HTML);
option.setOutputFileName("c:/temp/sample.html");
task.setRenderOption(option);

try{
task.run();
out.println("Created Report ");
} catch(EngineException e){
out.println("Report" + fileName + "failed");
out.println(e);
}

It seems that you try to output the HTML in a file ("c:/temp/sample.html") instead of giwing it back from the jsp.
I have no experience with jsp but you should try to send it to the OutputStream, something like that (which is from a Servlet):

ServletOutputStream servletOutputStream = response.getOutputStream( );
option.setOutputStream( servletOutputStream );

But I don't know how to get the output stream from within a jsp script.

Thanks for helping me out so far. What you described seems to be my
option.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_HTML); part. my
option.setOutputFile works perfectly fine b/c i get an output file with
what the rptdesign documents looks like. I am still troubleshooting but
any suggestions would be of help. Thanks

Adam,

From the several emails you have posted, I assume you are trying to use
report engine in JSP page to display the output in a browser, but you
see nothing in the browser. However, you did see an HTML file generated
on disk, right?

If that is the case, you do need to pass your JSP output stream to the
engine for it to generate output to. That is what the function
setOutputStream is for (as compared to setOutputFileName).

There is a Viewer web-application shipped with BIRT. Please check out
that applicaiton for further details. That app is directly deployable.

Stanley,
Thanks for the response. I have been looking at the
setOutputStream method but I am not getting very far with it.
setOutputStream takes in parameters (OutputStream ostream). This is where
i am lost. Could you explain from my code earlier what else i have to put
in. Thanks. I will be continuing to look at it.
