how to integrate birt report

[Al Y, geändert vor 16 Jahren.]

I would like to view a BIRT report within a liferay portlet. Has anyone had success in deploying a birt portlet? How come there are no articles mentioning BIRT? <frustrated BIRT report developer></frustrated BIRT report developer>

[Roman Hoyenko, geändert vor 16 Jahren.]

I haven't seen a discussion about this portlet here in the community. Is there a JSR-168 compliant portlet available to view BIRT reports? If there is it should work within Liferay.

[Al Y, geändert vor 16 Jahren.]

There is and isn't. Actuate has developed birt portlets (not sure if they are JSR168) for their own iPortal software, which I believe is also based on Liferay. However, it is highly customized to that environment. So in reality, there isn't, hence the need to perform integration. So can anyone shed light on this?

[Roman Hoyenko, geändert vor 16 Jahren.]

Well, if it is based on Liferay, I am pretty sure it could be installed. Did you try to deploy it on Liferay?

[David Hay, geändert vor 16 Jahren.]

Any success with this? We're looking to do the same thing...

[Al Y, geändert vor 16 Jahren.]

Nope, not yet. Still working on it.

I'm much surprised due to the popularity of BIRT that there isn't more support the subject.

Did you see this?

Hi Guys,
I was successfully able to integrate birt report with Liferay portlet.
I just followed above link (http://wiki.eclipse.org/Portlet_Example_%28BIRT%29_2.1) . But i got problem of getting reference to PortletContextImpl. Even after adding the jar in classpath, I got class cast exception. Moreover, it made the portlet non JSR compliant implying that it could not be ported directly to other portal servers.

Then instead of passing ServletContext in WebReoprt.java, I used PortletContext.
PortletContext pc = req.getPortletSession().getPortletContext();
this.birtReportEngine = BirtEngine.getBirtEngine(pc);

In BirtEngine.java, I used following approach:

config.setEngineHome(pc.getRealPath("/WEB-INF/platform"));
//IPlatformContext context = new PlatformServletContext( sc );
//config.setPlatformContext( context );

Then everything works fine!

That's great news, Ashutosh! I was talking to someone interested in Liferay today and he was also interested in using BIRT.

If you send us the portlet, we can make it available in the portlet repository. What do you think?

Hi,

plz help me....

I built BIRT report into liferay and it works generating HTML
reports. But I need PDF format, so I changed to
resp.setContentType("application/pdf"); and
OUTPUT_FORMAT_PDF
but I don't get any output, just a blank screen.
In Eclipse preview, the PDF works.

[Ganesh Ram, geändert vor 15 Jahren.]

I tried building the portlet using the instructions here.

The IReportEngineFactory object is always null.

EngineConfig config = new EngineConfig();
config.setEngineHome("");
//config.setBIRTHome(sc.getRealPath("/WEB-INF/platform"));
IPlatformContext context = new PlatformServletContext(sc);
config.setPlatformContext( context );

try{
	Platform.startup( config );
}
catch ( BirtException e )
{
	e.printStackTrace( );
}
IReportEngineFactory factory = null;
try{
	factory = (IReportEngineFactory) Platform.createFactoryObject("org.eclipse.birt.report.engine.api.impl.ReportEngineFactory");
}
catch(Exception e){
				e.printStackTrace();
}
						
System.out.println("factory: "+factory);

How did you guys get the birt portlet running ?
Any mistake that iam doing ?

[xavi c o, geändert vor 15 Jahren.]

I guess that's the code for BirtEngine.java. If so:

config.setEngineHome("");
//IPlatformContext context = new PlatformServletContext( sc );
//config.setPlatformContext( context );
config.setEngineHome(sc.getRealPath("/WEB-INF/platform"));

Also, you need to change the receiver parameter "ServletContext sc" for "PortletContext sc", and import the package "javax.portlet.PortletContext;", of course.

Good luck !!

I got it working !
I had not put the platform\configuration\config.ini file.

Hi Ganesh

That's great that you have made the BIRT portlet working in Liferay.

Do you plan to share your work in Liferay community? Love to play with the BIRT portlet.

Thanks

What might be the problem


Thanks in advance

I can't get my birt portlet/app deployed, did anybody get theirs working by following the directions in the links above?

[donino donino, geändert vor 12 Jahren.]

Have a look on this jsr 286 Birt Portlet project, the whole site including the reports live demo work on a standard bundle Liferay 6.1. Enjoy!

[Philippe CHEIPE, geändert vor 12 Jahren.]

Perhaps try this way:

It's an old post, but should still work.
