I defined a module, put all the jars in it and had to define some dependencies, one on the xml DocumentBuilderFactory. I defined a module javax/xml/parsers with xml-apis.2.0.jar. But now I get: Failed to install plugin from jar:file:C:%5Cjava%5Cjboss%5Cjboss-as-7.0.1.Final%5Cmodules%5Corg%5Ceclipse%5Cbirt%5Cmain%5Corg.eclipse.birt.runtime_3.7.1.v20110913-1734.jar!/: java.lang.ClassCastException: __redirected.__DocumentBuilderFactory cannot be cast to javax.xml.parsers.DocumentBuilderFactory at javax.xml.parsers.DocumentBuilderFactory.newInstance(Unknown Source) [:1.6.0_24] at org.eclipse.birt.core.framework.jar.BundleLoader.loadExtensions(BundleLoader.java:147) [org.eclipse.birt.runtime_3.7.1.v20110913-1734.jar:] at org.eclipse.birt.core.framework.jar.BundleLoader.load(BundleLoader.java:63) [org.eclipse.birt.runtime_3.7.1.v20110913-1734.jar:] at org.eclipse.birt.core.framework.jar.ServicePlatform.installBundle(ServicePlatform.java:57) [org.eclipse.birt.runtime_3.7.1.v20110913-1734.jar:] at org.eclipse.birt.core.framework.jar.ServiceLauncher.startup(ServiceLauncher.java:71) [org.eclipse.birt.runtime_3.7.1.v20110913-1734.jar:] at org.eclipse.birt.core.framework.Platform.startup(Platform.java:75) [org.eclipse.birt.runtime_3.7.1.v20110913-1734.jar:] at org.jboss.tools.birt.servlet.BirtEngine.getBirtEngine(BirtEngine.java:56) [jboss-birt-servlet.jar:] Any idea of how to solve this?
