Re: [rules-users] execution using "java -jar x.jar ..." fails

See <http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/java.html> http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/java.html Key line' referring to the -jar option: "When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored." You can specify the path to external jars in the manifest of the standalone jar.

In Eclipse, I created a jar file x.jar from the .class and a few .drl files, and copied x.jar to /tmp/x/ Now, in /tmp/x CP="droos/*:drools/lib/*" java -cp "$CP" -jar dpvt.jar par... This fails on the first attempt to access any class from a drools jar file. In /tmp/x, I unpack x.jar and call CP="droos/*:drools/lib/*:." java -cp "$CP" rss.aws.init.Main par... AND THIS WORKS! So, what is different when starting a Java program with java -jar as opposed to java x.y.Main?
