I did it !
My steps:
1 - First create a new Seam Web Application with Birt face and make sure its working properly.
2 - Create a new Seam Web Application and download Birt runtime 3.7.0 copy birt-runtime-3_7_0/ReportEngine/lib to WebContent/WEB-INF/lib
3 - copy the following jars from /WebContent/WEB-INF/lib
jboss-birt-servlet.jar
jboss-seam-birt.jar
viewservlets.jar
axis.jar
commons-discovery-0.2.jar
4 - Copy this files to the new WA:
/WebContent/WEB-INF/tlds
/WEB-INF/viewer.properties
/WEB-INF/server-config.wsdd
5 - Create this pastes:
documents
scriptlib
report
report/images
logs
6 - Add this to the web.xml
I can render my test report created with a separeted report Desing using:
<b:birt designType="embed" designName="AnexoI.rptdesign"
embeddable="true">
<b:param name="reportTitle" value="Customers Contacts" />
<b:param name="Cust" value="543" />
</b:birt>
