Using BIRT with jsf4birt.jar on tomcat server/websphere [message #849729]

Hello All,

For few days I am working on BIRT and jsf4birt. I have followed the below mentioned steps to display charts generated by BIRT on jsp page using "birt:birtWrapper" tag.

1. Copied all the JARs from Report Engine to my project/WEB-INF/lib directory.

2. Copied the birt-runtime/Report Engine/plugins and birt-runtime/ReportEngine/configuration directories to the platform directory.

Added the required context params to the web.xml.

Used as :

<birt:birtWrapper id="t" reportDesign="/reports/new_report.rptdesign" rendered="true">
<f:param name="country" value="USA"></f:param>
</birt:birtWrapper>

Report name : new_report.rptdesign

When I start the server I get the below exception :

SEVERE: JSF1054: (Phase ID: RENDER_RESPONSE 6, View ID: /workpages/pageb.jsp) Exception thrown during phase execution: javax.faces.event.PhaseEvent[source=com.sun.faces.lifecycle.LifecycleImpl@1f528ab]

Platform details :

JSF Version : 1.2
Java Compiler : 1.5
Tomcat Version : 6
IDE : Eclipse Indigo/RSA

Please help as I have checked all the links but I get the above mentioned error.

Thanks Jason for your reply. Your replies are very helpful.

Birt runtime version : 3_7_2

I have also copied jars from the lib folder of exadel-jsf4birt-demo module.
The jsf tags are working fine but the page with birt:birtWrapper is causing the exception.

And added the following context-params in web.xml

<context-param>
<param-name>actuate.serverUrl</param-name>
<param-value>http localhost:8900 iportal</param-value> (cant add links, that is why typed the url in this way)
</context-param>

<context-param>
<param-name>actuate.serverLogin</param-name>
<param-value>administrator</param-value>
</context-param>

<context-param>
<param-name>actuate.serverPassword</param-name>
<param-value></param-value>
</context-param>

I am also adding the screen shots of the jars added since module size exceeds the permitted file size.

Finally the code worked for me. Steps to be followed are as follows :

1. Make a dynamic web project (jsf project if you want to use jsf tags).
2. Once your project is ready prepare your report. Prepare your data sets for report/chart generation, a sample query is mentioned below.

select count(customernumber) cuscount,State
from customers
where country=? -- this is the parameter you can give as input
group by state

3. Once you are done with this part add following parameters to web.xml

<context-param>
<param-name>actuate.serverUrl</param-name>
<param-value>http: localhost:8900 iportal</param-value>(please add //,/ respectively in the blank spaces.)
</context-param>
<context-param>
<param-name>actuate.serverLogin</param-name>
<param-value>administrator</param-value>
</context-param>
<context-param>
<param-name>actuate.serverPassword</param-name>
<param-value></param-value>
</context-param>
<context-param>
<param-name>org.eclipse.birt.configPath</param-name>
<param-value>/configuration/config.ini</param-value>
</context-param>

Place the configuration folder inside WEB-CONTENT.

If this is not done properly you can get null pointer exception.

4. Copy the "platform" folder inside WEB-INF.

5. The list of required jars are mentioned in the screen attached with this post.
(Downloading the dummy module of jsf4birt from exadel website will be helpful).

6. A tricky part that I found after struggling for few days. If you get version mismatch error or unsupported exception, open your reportfile.rptdesign in text editor u will get something like
<report xmlns="http //www.eclipse.org/birt/2005/design" version="3.2.20" id="1">

Change this version to the one that is supported by your server/IDE. I changed it from 3.2.23 to 3.2.20.

7. Finally the birt:birtWrapper worked for me. Where country is my parameter.

<birt:birtWrapper id="t" reportDesign="customerdetails.rptdesign" rendered="true">
<f:param name="country" value="#{form.country}"></f:param></birt:birtWrapper>

And then finally it worked for me.

I am trying to explore more features of BIRT like adding comments to a point on chart and generating reports in pdf format. Please do let me know if you are aware of these stuffs.

Special thanks to Jason for his valuable posts !!
