BIRT with JBOSS portal

saravanam

I am using jboss portal 2.7.2 and Birt 2.5.1. I have deployed the jbossbirtportlet example given. If i render the report to an html file throught runandrender task it works fine. But when I want to see the report in portlet it is not working. There is no error in the log as well. I am using options.setOutputStream(rResponse.getPortletOutputStream()); to send the output to portlet. It is just showing null in the portlet.

Below is the RE Log entry:

After this there is html emitter startup and writes the table, cell and ends. But the output is not coming to the portlet.

please try to use jboss portal 2.6.8. It seems that jboss portal 2.7.2 have some compaitibility problem.

saravanam

Thanks Alex. I have already tried with jboss portal 2.6.2 and 2.6.8 and found that BIRT 2.5 works with both of them. I have only issue with 2.7.2.

Not sure whats wrong here but for some reason JBoss is not using the outputstream. I know its getting populated because I used an intermediate ByteArrayOutputStream and wrote it out to a file and it worked properly.

As a work around try something like (Modified do View):

protected void doView(RenderRequest rRequest, RenderResponse rResponse) throws PortletException, IOException, UnavailableException {

this.birtReportEngine = BirtEngine.getBirtEngine(rRequest.getPortletSession().getPortletContext());

logger.log( Level.FINE, "my image directory " + rRequest.getPortletSession().getPortletContext().getRealPath("/images"));

IReportRunnable design;
try
{
rResponse.setContentType("text/html");

//Open report design
design = this.birtReportEngine.openReportDesign( rRequest.getPortletSession().getPortletContext().getRealPath("/Reports/TopNPercent.rptdesign"));
//create task to run and render report
IRunAndRenderTask task = birtReportEngine.createRunAndRenderTask( design );

//set output options
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_HTML);
options.setImageHandler( new HTMLServerImageHandler() );

ByteArrayOutputStream fso= new ByteArrayOutputStream();
//options.setOutputStream(rResponse.getPortletOutputStream());
options.setOutputStream(fso);
options.setBaseImageURL(rRequest.getContextPath()+"/images");
options.setImageDirectory(rRequest.getPortletSession().getPortletContext().getRealPath("/images"));

task.setRenderOption(options);
//run report
task.run();

task.close();

PrintWriter writer = rResponse.getWriter();
writer.write(fso.toString());
writer.close();

}catch (Exception e){

e.printStackTrace();
throw new javax.portlet.PortletException( e );
}
}

not certain if the write ByteArrayOutputStream.toString will cause an issue, but it worked with my testing.

Thanks a lot Jason. It is working for me as well.
