Doing more testing at work today, and decided to pickup the latest compiled output from the build server.
Exception occured in J2EEC Phasejava.lang.IllegalArgumentException: Unknown ContainerTransaction type [Requires]
com.sun.enterprise.deployment.backend.IASDeploymentException: Error loading deployment descriptors for module [EJB FILE] — Unknown ContainerTransaction type [Requires]
Pinged one of the developers about that, and apparently it means that the transaction-type in ejb-jar.xml is wrong. Yay. For a reason I cannot fathom, Google had no results for this error either.
