Re: [rules-users] Drools examples don't run

Hello, I think you have to add the xstream jar to your classpath. Here is the Maven dependency : <dependency> <groupId>com.thoughtworks.xstream</groupId> <artifactId>xstream</artifactId> <version>1.3.1</version> </dependency> Best regards, Bruno. 赵侃侃 a écrit : Hello, I checked out the latest source from svn repository. It compiled OK and imported the example projects to my eclipse workspace but the examples run with error. The two example projects are namely drools-examples-drl & drools-examples-fusion. org.drools.examples.pacman.Main gives the errors: Exception in thread "main" java.lang.NoClassDefFoundError: com/thoughtworks/xstream/XStream at org.drools.audit.KnowledgeRuntimeLoggerProviderImpl.newThreadedFileLogger(KnowledgeRuntimeLoggerProviderImpl.java:34) at org.drools.logger.KnowledgeRuntimeLoggerFactory.newThreadedFileLogger(KnowledgeRuntimeLoggerFactory.java:69) at org.drools.examples.pacman.Main.initKsession(Main.java:88) at org.drools.examples.pacman.Main.main(Main.java:39) Caused by: java.lang.ClassNotFoundException: com.thoughtworks.xstream.XStream at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 4 more org.drools.examples.broker.Main gives the errors: java.lang.NullPointerException at org.drools.compiler.PackageBuilder.addProcessFromXml(PackageBuilder.java:432) at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:468) at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28) at org.drools.examples.broker.Broker.loadRuleBase(Broker.java:95) at org.drools.examples.broker.Broker.createSession(Broker.java:80) at org.drools.examples.broker.Broker.<init>(Broker.java:57) at org.drools.examples.broker.Main.main(Main.java:53) Does anyone experience the similar issues and know how to fix that?
