Integrate BIRT 4.2.1 with JSF 2.0 [message #937754]

Tue, 09 October 2012 04:27

Eclipse User

I am trying to integrate BIRT 4.2.1 with JSF 2.0 (we're using Primcefaces 3.4) running on Glassfish 3.1.2.2.

We are busy investigating all possible open source solutions for our reporting engine needs. BIRT seemed perfect except that we are unable to integrate it with our JSF 2.0 GUI. I have googled and found jsf4birt but the library does not seem to support JSF 2. Also busy looking at jboss-birt-servlet.jar but have not had any success.

In essence, any suggestions/help on this matter will be highly appreciated? Is there anyway to integrate BIRT with JSF 2.0 and where can I find more information on how to accomplish this? Surely this can not be too difficult?

Have you tried using BIRT tag library with JSF?

Hi Jason,

Thank you for replying. I have started reading about the tag library and will try to implement it immediately. It sounds perfect. I will let you know if I run into any problems, hoping it is as simple as it sounds? Razz

Jason, would you say this is the best way to integrate BIRT 4.2.1 with JSF 2.0 at the moment and secondly is there a step-by-step directions somewhere for this?? If not, perhaps we can post something somewhere once I get it working? Wink

Hi Jason,

I am looking at the Viewer tag libraries solution and can't find any the mentioned libraries:

".. and copying coreapi.jar, modelapi,jar, viewerservlets.jar, engineapi.jar, and com.ibm.icu_version.jar from the Viewer libs "

Am I suppose to download them from somewhere or are these old jars? I'm using BIRT 4.2 right? I could find a viewservlets.jar for instance not a viewerservlets.jar. and the com.ibm.icu jar in the WebViewerExample/WEB-INF/lib/ folder of the BIRT Runtime package. Also what should the namespace def be for the taglib in my facelet? Do I need anything specific in my web.xml file?

4. Very simple BIRT report that doesn't take any paramters for now.

When I deploy the application on Glassfish, I don't see any errors, but unfortunately I don't see any viewer or report either. I only see my primefaces components.

What am I missing?

I know there have been some issues with JSF 2.0.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=367192
A couple of options. One is to deploy the viewer to a separate web app and then use url integration to the birt viewer app. Another option alluded to in the bug is to use the h:outputText tag
http://www.mkyong.com/jsf2/jsf-2-outputtext-example/
Download the runtime for birt 4.2 add all the jars in the report engine/lib directory to your webapp classpath and then call the Report Engine API to create and render the report in HTML.

RunAndRenderTask task = null;
IReportEngine engine = null;
EngineConfig config = null;

try {
config = new EngineConfig();

Platform.startup(config);

IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
engine = factory.createReportEngine(config);

IReportRunnable design = null;
// Open the report design

design = engine.openReportDesign("Reports/myreports.rptdesign");
task = (RunAndRenderTask) engine.createRunAndRenderTask(design);
task.setLocale(new Locale("en", "US"));
HTMLRenderOption options = new HTMLRenderOption();
options.setSupportedImageFormats("JPG;PNG;BMP;SVG;GIF");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
options.setOutputStream(bos);
options.setOutputFormat("html");
options.setEmbeddable(true);

task.setRenderOption(options);
task.run();
task.close();
engine.destroy();
} catch (Exception ex) {
ex.printStackTrace();
}
Platform.shutdown();
System.out.println("Finished");

If you use this approach make sure to only startup the platform once when your app starts up. Shut it down when your app is closing. Wrap access to the engine creation code in a singleton and create a new task with the engine for every report request. Also make sure to close the task when the report is complete.

Hi James,

thank you for the detailed information and help! I finally got it working! BIRT on a JSF 2.0 facelet Smile

But it's only a prototype at the moment, so obviously need to still look at your suggestions of starting and stopping the engine within the application.

On another note, the report came back with quite a significant amount of data without any pagination resulting in the browser becoming almost unresponsive. Is there an easy way of automatically restricting the amount of records displayed with a sort of next, previous type navigation around the report data? And as for the save as pdf and excel buttons etc, I take it I need to build those myself and simply change the output format to PDF for example?

You can always separate the tasks and have a run task that creates a rptdocument and then a render task to render specific pages or a page range.

engine = factory.createReportEngine( config );

IReportRunnable design = null;
design = engine.openReportDesign("Reports/Test.rptdesign");
IRunTask task = engine.createRunTask(design);
task.setLocale(new Locale("en", "US"));
task.run("output/resample/Test.rptdocument");
task.close();

document = engine.openReportDocument("output/resample/Test.rptdocument");

HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat("html");
options.setOutputFileName("output/resample/test.html");
options.setSupportedImageFormats("PNG;GIF;JPG;BMP;SWF;SVG");
options.setOption( IRenderOption.HTML_PAGINATION,Boolean.TRUE );

IRenderTask rtask = engine.createRenderTask(document);
rtask.setLocale(new Locale("en", "US"));
rtask.setRenderOption(options);
//rtask.setPageNumber(1);
//rtask.setPageRange("1,3-6");
rtask.render();
rtask.close();
document.close();

I am not certain this will help the performance though. It may be better to cut down the amount of data or look at implementing a progressive viewing scheme like what John Ward wrote up:
http://digiassn.blogspot.com/2007/10/birt-progressive-viewing-during-render.html
If you use John's approach make sure to not set birt home if you are using BIRT 3.7 or greater.

Thank you Jason,

This is so helpful. Will try and implement either and let you know how it went!

I used managed bean in JSF for rendering birt report on birt viewer. Here is code:

package com.jsf.report.birt;

import java.io.IOException;

import javax.faces.bean.ManagedBean;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletRequest;

@ManagedBean(name="birt")
public class BirtClass {

	public BirtClass() {
		System.out
				.println("-----------------------------------------------------------");
		System.out
				.println("-------------- BirtClass Default Constructor --------------");
		System.out
				.println("-----------------------------------------------------------");
	}

	private String URL = "/frameset?__report=reports/students.rptdesign";

	public void BirtViewer() throws IOException {
		HttpServletRequest request = (HttpServletRequest) (FacesContext
				.getCurrentInstance().getExternalContext().getRequest());
		URL = request.getContextPath() + URL;
		System.out.println("-----------------------------------------------------------");
		System.out.println("BirtViewer() :: Complete Report Path=\"" + URL + "\"");
		System.out.println("-----------------------------------------------------------");

		FacesContext.getCurrentInstance().getExternalContext().redirect(URL);

	}
}

Here is my JSF page with .xhtml extension:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<h:form>
Click on View Button :
<h:commandButton id="btn" action="#{birt.BirtViewer}" type="submit" value="Preview Report"/>

</html>

Add birt configuration in web.xml and jsf servlet configuration also.
