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/

Thomas *From:* rules-users-bounces(a)lists.jboss.org [mailto: rules-users-bounces(a)lists.jboss.org] *On Behalf Of *Wolfgang Laun *Sent:* 23 June 2010 15:45 *To:* rules-users(a)lists.jboss.org *Subject:* [rules-users] execution using "java -jar x.jar ..." fails The application works fine in Eclipse. 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.

When you launch with -jar, the classpath is ignored and the jar content is used only. See -jar documentation: "When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored." regards 2010/6/23 Wolfgang Laun <wolfgang.laun(a)gmail.com&gt; > The application works fine in Eclipse. > > 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 > > _______________________________________________ > rules-users mailing list > rules-users(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > > _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
