If you are using Eclipse Version: 3.4.0 ,you can set the path of "org.eclipse.jdt.core_3.4.0.v_814.jar" as external jar in your drools project(reflect in classpath). The location of jar is Eclipse(Folder) -----> Plugin(Folder) -----> org.eclipse.jdt.core_3.4.0.v_814.jar. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Shigeaki Wakizaka Sent: Thursday, February 26, 2009 8:12 PM To: rules-users(a)lists.jboss.org Subject: [rules-users] How to set JANINO compiler with Drools5 M5 Hi. I'm kind of new to Drools5.0. Could I ask you guys how to set JANINO compiler with recent API? I just run the sample drl with EclipseIDE, which is download from drools site, and then the error occured- The Eclipse JDT Core jar is not in the classpath. So, I just want to know why this happens and how to set another compiler to retry. Thanks in advance. waki _______________________________________________ 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
