Deploying BIRT Report Engine API with Jakarta Struts

Deploying BIRT Report Engine API with Jakarta Struts

After reading the great article Deploying BIRT from Jason Weathersby I decide to create a little example on how to use BIRT RE API with Jakarta Struts framework.

To do so I’ve followed Jason steps:

Create a WebReport/WEB-INF/lib directory underneath the Tomcat webapps directory.
Copy all the jars in the birt-runtime-2_1_0/ReportEngine/lib directory from the Report Engine download into your WebReport/WEB-INF/lib directory.
Next, create a directory named platform in your WEB-INF folder.
Copy the birt-runtime-2_1_0/Report Engine/plugins and birt-runtime-2_1_0/ReportEngine/configuration directories to the platform directory you just created. In this example the context is WebReport, so the folder structure is /webapps/WebReport/platform/plugins and webapps/WebReport/platform/configuration.
Additionally, create directories below WebReport for image location and report location.

and used the same directory structure:

WebReport directory structure

The example allows you to generate reports in HTML, PDF, and XLS formats. For the last one I’ve used Tribix XLS Emitter.

To get more information about how to use XLS emitter with BIRT Report Engine API please read the README file that comes with in the binary distribution.

The following files are mean to replace the WebReportServlet class from Jason example.
Go to the Resources section to get the instructions on how to get this example source code.
The source code has been updated so you can easily embed the report’s HTML in your JSP pages and correctly render your images and charts in your HTML.

All you need to get this sample running is to copy the WAR file to your server deploy dir and configure the BIRT Report Engine logging in BirtConfig.properties file.

^?View Code TEXT

1 2	logDirectory=e:/Work/logs/birt logLevel=CONFIG

If you are building the application from the source code you must also configure the application server deployment directory, rename the file build.properties-example to build.properties and edit the following line.

^?View Code TEXT

1	deploy.dir=E:/Work/jboss/server/default/deploy

Designing the report is out of the scoope of this article, you can found a lot of tutorials on the Web and BIRT Website.

Great example. It would be great if you could add this to the Eclipse Wiki.
Take a look at this site:
http://wiki.eclipse.org/index.php/Servlet_Example

If you have a Bugzilla account you can post it in the comments section of this example.

Thanks

Hi,

thank you for this valuable example, thank you Jason too.

Actually, I’m developing a web application that allow users to generate reports based on some parameters. So, I do need to access a database on the fly (run time). But in this example, and in Jason’s one I’m not able to find something like that, because your rpdesign file is already generated (maybe using the report designer in eclipse.

Also, I’m using Struts as an MVC framework, and don’t want to violate my design by using the BIRT viewer servlet, So what about the AJAX facilities in this case? I do want to take advantage of it

This article is just about the deployment of the BIRT Report Engine and have it running.

But you can found more info about how to use the Report Engine API to satisfy your needs (passing parameters in runtime and integrating with your web application without using BIRT Viewer) in this page:

http://www.eclipse.org/birt/phoenix/deploy/

Hope this help,
Samuel

Thanks A lot Sam for your reply. Actually,I eventually adopted a combination of Displaytag and the jfreechart based cewolf taglib (because of deadlines ;). Nonetheless Birt Report engine API seems to be more powerful so I’ll keep investigating this solution and glance through the page you gave me.

Thanks,
Yassine.

Nice article. However i observed an issue - the generated output i.e., the html will have “file://c:……” reference to the images instead of URL (even though we specify the baseImageUrl).

I have tested this with one of my report which contain charts. I found that charts , in the form of images, are aptly created in the specified images directory, but fail to display on the browser since the fully qualified path contains file: protocol instead of http:

Am i missing anything?

Thanks
Satya

Oh, i have added the following lines and now its working:

————————
htmlemitterconfig.setActionHandler(new HTMLActionHandler());
htmlemitterconfig.setImageHandler(new HTMLServerImageHandler());
config.getEmitterConfigs().put(”html”, htmlemitterconfig);
—————————-

Thanks a lot Satya for reporting this.

I’ll update the code as soon as I can.

good example!! it really helps a lot for me.

The source code has been updated to fix the bug reported by Satya.

April 3, 2007 at 01:36

The BIRT Runtime has been updated to Release Build 2.1.2

Can anyone tell me, i have created a report which uses a library.
Now i try running this report on some other machine which has web viewer installed. Where do i copy the library contents so that the report picks them up properly.
I am using jboss as my server.
Please help!

you said ‘The source code has been updated so you can easily embed the report’s HTML in your JSP pages and correctly render your images and charts in your HTML.’
Can you give further explanations on how to do that ?

June 12, 2007 at 01:04

Looking at the WebReportAction you can easily put the report in the request request.setAttribute("reportHTML", out); and print it in the jsp like ${reportHTML} in viewReport.jsp file.

Hi Samuel,
I came across these error while I’m deploying birt to struts 1.3.8 with tiles and sslext. Pls advice whether Birt came deployed to which struts version and what went wrong with it ? Thanks in advance.

This example was deployed with Struts 1.2.9, I’ve never used Struts 1.3.x or Struts 2.x. Stripes Framework rules

Hi, Thanks a lot for your example!
I met a problem that when I deployed your example to my system,
I found the var factory in the BirtEngine.java is null.
How can I fix it?
May you do me a favor?
Thanks very much!

Sorry, but I can’t reproduce the error.
I deployed the war into jboss and all seems to work normally.

Hello,
Greate example. I am trying to integrate it in my J2ee web application, and i would like to know if all the libraries and files in
WEB-INF\platform\plugins necesary in run time?

Thanks in advanced!

December 20, 2007 at 08:51

Thats really important to know if all the files are required under platform. Actually if we can cut down the number of jars the application becomes light. It is also now know if we need all the jars (18 jars) under WEB-INF\lib. Compile time dependency need only 3 jars in the lib.

Thanks for the help

Hi,
I didn’t try to remove the files.
I’ve just followed the documentation which tells to copy all the files.
I assume that since they come bundled with the Report Engine it’s probably because they are necessary.
