I am using JBoss Seam 2.2.0.GA with BIRT and trying to embeed birt reports into my Seam application.
- With BIRT 2.5.1 I found a date paremeter problem. Whenever I pass a date parameter to JBossBirtServlet it converts the parameter to 'java.util.Date', but BIRT requires a 'java.sql.date'. Running the report an error message states this problem.
- With BIRT 2.5.2 the problem is even worse. It is not even possible to render the report:
java.lang.NoSuchMethodError: org.eclipse.birt.report.engine.api.IReportEngine.createGetParameterDefinitionTask(Lorg/eclipse/birt/report/engine/api/IReportRunnable;)Lorg/eclipse/birt/report/engine/api/IGetParameterDefinitionTask;
Searching jboss-birt-servlet.jar source code was dificult: it doesn't exits in JBoss Tools Repositorie. It only is included compiled at:
http://anonsvn.jboss.org/repos/jbosstools/tags/jbosstools-3.1.0.GA/birt/plugins/org.jboss.tools.birt.core/resources
Finally I found its source code as a attachment to https://jira.jboss.org/jira/browse/JBIDE-2220
I have modified JBossBirtServlet code to correct this problems.

The corresponding jars are atached to this post.
'jboss-birt-servlet.jar' and 'jboos-seam-birt.jar' should be revised with each new BIRT version. If you use JBoss Proyect Wizard to create a new proyect and select BIRT facet, this files are included at /WEB_INF/lib directory with all the other libraries of the installed BIRT version, so it should run with it !!
Indeed, in order to install JBoosTools 3.1.0 Plugin you have to update your Birt version to 2.5.2, so there is no chance to use previous versions of birt.
I hope this can help to other Seam-Birt users with the same problem.
