No, the NPE is all I've got in the console output. Can you detail what process definition that you are referring to? I saw all the rules definition files are all copied over to the classpath after conducting the compile.
Namely, those files are borker.drl, notify.drl, position.drl, position.rf and stocktickstream.dat. All of them now exist under project-root/target/classes Best Regards, Kevin Zhao 2010/10/21 Michael Anstis <[email protected]> > Are there any errors in addition to the NPE? > > The context of the stack-trace suggests the process definition being loaded > is not on your classpath. > > 2010/10/21 赵侃侃 <[email protected]> > > Thanks Bruno, >> >> I have now fixed the NoClassDefFoundError, any ideas about the NullPointer >> one? >> >> Best Regards, >> Kevin Zhao >> >> 2010/10/20 Bruno Freudensprung <[email protected]> >> >>> >>> 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.
