Hello, I am part of the Switchyard community. We had a set of plugins working for Forge1.0.0.Alpha4 and we now need to move forward to Forge1.0.0.Beta3. In Alpha4 we were installing the plugins just copying the jars in the libs dir. Now, to test the plugins, we need to instruct forge to install them itself. When I execute the command "forge source-plugin <puglin_src_dir>" everything works OK: the plugin gets compiled and installed in my .forge dir inside my home dir. However, after the installation, when I run forge, it does not start and throws the following error: log4j:ERROR A "org.apache.log4j.xml.DOMConfigurator" object is not assignable to a "org.apache.log4j.spi.Configurator" variable. log4j:ERROR The class "org.apache.log4j.spi.Configurator" was loaded by log4j:ERROR [ModuleClassLoader for Module "org.jboss.forge:main" from local module loader @335856a5 (roots: D:\tools\forge-1.0.0.Beta3\modules,C:\User s\mario\.forge\plugins)] whereas object of type log4j:ERROR "org.apache.log4j.xml.DOMConfigurator" was loaded by [ModuleClassLoader for Module "org.switchyard.switchyard-forge-plugin.dependencies:0. 3.0-SNAPSHOT-bee75bd4-471b-49c3-9cd2-d1ca8b531098" from local module loader @335856a5 (roots: D:\tools\forge-1.0.0.Beta3\modules,C:\Users\mario\.forge \plugins)]. log4j:ERROR Could not instantiate configurator [org.apache.log4j.xml.DOMConfigurator]. log4j:WARN No appenders could be found for logger (org.jboss.weld.Version). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

But why is that? I can see forge-shell-api.jar (the jar containing the required class) is in the <forge-1.0.0.Beta3>\modules\org\jboss\forge\shell-api\main dir I would appreciate any good tip! Thanks in advance Mario
