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

What’s in your manifest in your jar file? From the extracted stuff, as proposed my Eclipse's jar builder:

OK, typo, I'm using the same (correct) paths to /extra/drools-5.1.0.M2/

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? The stack dump is not very informative: java.lang.NoClassDefFoundError: org/drools/KnowledgeBaseFactory at rss.aws.engine.impl.DroolsEngine.setup(DroolsEngine.java:30) at rss.aws.init.Core.init(Core.java:51) at rss.aws.init.Core.getInstance(Core.java:16) at rss.aws.init.Main.<init>(Main.java:35) at rss.aws.init.Main.main(Main.java:191) Caused by: java.lang.ClassNotFoundException: org.drools.KnowledgeBaseFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:319) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:264) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:332) ... 5 more Any ideas? -W ------------------------------ ************************************************************************************** This message is confidential and intended only for the addressee.
