LinkageError Seam 2.2.1.x and BIRT 2.6.1
Environment: JBoss 5.1.0.GA, Seam 2.2.1.CR3, BIRT runtime 2.6.1, jboss-birt-servlet.jar and jboss-seam-birt.jar extracted from JBoss Tools 3.0.3.GA.
Following instructions from here:
http://wiki.eclipse.org/Seam%28BIRT%29Recipe, and http://www.seamframework.org/Community/BirtIntegrationIntoExistingSeamProject, I get the following exception when the report begins to render. I'm a bit at a loss to understand how to resolve this, and was wondering if anyone had any suggestions. Exception follows:
