Hi all... I've posted this to the Velocity mailing list, and will create a support request with the Red Hat Developer Studio (a branded version of Eclipse) people, but thought I'd cover my bases and ask here as well/ I'm attempting to use Eclipse/JBoss to generate web service artefacts from an implementation class. Everything appears to proceed smoothly, but then we get the below stacktrace. Researching this, it appears to be related to Velocity 1.7 and its use of classloaders and default class implementations. Does anyone know a smart way around this? Given that this is part of the JBoss plugins for Eclipse, I don't have a lot of control over how it works, so the couple of clever ways around this I've found online aren't available to me (it's not a problem with code I'm writing, but with the Eclipse plugin's use of Apache CXF, and IT'S use of Velocity. Any suggestions would be grand. :-) We're using "Red Hat JBoss Developer Developer Studio" (a branded version of Eclipse) with this version info: Version: 10.4.0.GA Build id: GA-v20170511-1748-B62 Build date: 20170511-1748 This corresponds to Eclipse Neon. JBoss version from server startup message: JBoss EAP 7.0.7.GA (WildFly Core 2.1.17.Final-redhat-1) Java version 1.8 The stacktrace appears to indicate that Apache CXF (version 3.1.10 or 3.1.14) is used at least for part of the generation, but that the end-product will use JBossWS annotations, etc. I tried to mimic the call in the stacktrace using Ant, but it generates files that, on startup, JBoss recognizes as Apache CXF only and won't allow them (it displays a warning message). So whatever the plugin is doing appears not to be JUST what the stacktrace indicates (I get the sense that that is just the first step, and it might munge the generated files to conform to JBossWS standards). ------------------------------------- Failed to Generate Web Service code, please check the log for more details org.eclipse.core.runtime.CoreException: Could not find log4j.properties or
