Birt 2.3.0 report viewer ClassCastException

NerdyJoe

Hello,

First and foremost thanks for taking the time to look at my post and I hope you can provide some insight.

I am trying to build the report viewer from source and I'm running into a classCastException. I think I have the setup and build correct, maybe I am missing a jar somewhere? I downloaded the 2.3.0 source from dev.eclipse.org(Through CVS in eclipse). I have the 2.3.0 birt-report-desinger-all-in-one. Basically I ran the WebViewerPackager.xml Export War and would see what blew it up and would jar those pieces and add them to my Export War script appropriately.

The pieces I had to jar and add are
org.eclipse.birt.core
org.eclipse.birt.data
org.eclipse.birt.report.data.adapter
org.eclipse.birt.report.engine
org.eclipse.birt.report.model
and the WebViewerPackager creates the veiwerservlets.jar.

I drop the birt.war into tomcat(versions 6.0 and 5.5) and I fire it up and the birt page displays at localhost:8080/birt but when I click the link "View Example" only "+ org.eclipse.birt.chart.reportitem.ChartScriptableClassInfo" displays

I think I am just missing a jar, but the ExportWar runs without a hitch.
The jars that are in my apache-tomcat-6.0.20webappsbirtWEB-INFlib folder are

axis.jar
axis-ant.jar
chartengineapi.jar
com.ibm.icu_3.8.1.v20080530.jar
commons-cli-1.0.jar
commons-discovery-0.2.jar
coreapi.jar
dataadapterapi.jar

jaxrpc.jar
js.jar
modelapi.jar
odadesignapi.jar
org.apache.commons.codec_1.3.0.v20080530-1600.jar
org.eclipse.birt.report.engine.dataextraction_2.3.0.v20080611.jar

org.w3c.css.sac_1.3.0.v200805290154.jar
saaj.jar
scriptapi.jar
viewservlets.jar

Here is the error and again, thank for taking the time to look at this.

Hi NerdyJoe,

You could download the BIRT Runtime, and then look in the WebViewerExample directory to see what JAR files are used in that working example.

I'll move this thread to the BIRT Engine forums to see if others there have a better answer.
