Hi all,

I'm installing GSA off-board connector on a Window 2003 SP2 server.  jdk1.6.0_22, Connector-manager 3.0.2

After deploying the Connector.jar file into "connector-manager\WEB-INF\lib" and start Tomcat. the console output the following:

INFO: Loading XML bean definitions from URL [jar:file:/D:/GSAConnector/apache-tomcat-6.0.36/webapps/connector-manager/WEB-INF/lib/HelloWorld.jar!/config/connectorType.xml]

Many thanks,

This means you have developed the code in a higher java version than this one on the tomcat server.
Recompile it with the same java version which you use on your tomcat

Thanks, that solved it.
