Hi! I'm migrating to Eclipse Birt Runtime Engine 4.2.1 in my Java EE project with jre6 and Tomcat 6.0, this problem occurs when i deploy the project in Tomcat:

07-nov-2012 19:30:23 org.apache.catalina.core.StandardContext listenerStart 
GRAVE: Excepci├│n enviando evento inicializado de contexto a instancia de escuchador de clase org.eclipse.birt.report.listener.ViewerServletContextListener java.lang.SecurityException: class "org.eclipse.birt.report.engine.api.IExtractionOption"'s signer information does not match signer information of other classes in the same package
at java.lang.ClassLoader.checkCerts(ClassLoader.java:806) ...


I have deleted all the old libraries of Birt Runtime Engine 2.2 but the problem persists. The project compiles correctly with no errors.

I tried Classpath Checker and it tells this:

Jar conflicts between C:\Program Files\Java\jre6\lib\rt.jar and \xxxx_webapp\WEB-INF\lib\org.eclipse.birt.runtime_4.2.1.v20120918-1113.jar xxxx_webapp Unknown Classpath Checker Problem


It tells me that the class "org.w3c.dom.DOMConfiguration" is conflicting between rt.jar and org.eclipse.birt.runtime_4.2.1.v20120918-1113.jar

I tried to use jdk1.6 instead of jre6 and jr7 but with no success

Thanks a lot.

Hi again, i tried to erase IExceptionOption.class of the birt runtime jar, and the error is that Tomcat doesn't find the class IExceptionOption.

I tried to unsign the birt runtime jar, but then, the error is

org.eclipse.birt.core.exception.BirtException: Cant startup the OSGI framework


Any ideas please?

Thanks a lot.

Hi! Yes, the problem is that Birt uses OSGi runtime prior to 3.x version, and now, it uses POJO. Fortunately, Eclipse guys still distributes the new versions in OSGi runtime too. Then, download the "Report Engine OSGi deployment" from http://download.eclipse.org/birt/downloads/build.php?build=R-R1-4_2_1-201209181113. Everything worked right the first time with this Cool

Good luck!
