Hi All, I need urgent help in resolving this run time error. This is the first time we are deploying drools to websphere 6.1 and getting following error. Our organization does not allow us to do 'createClassLoader' in was.policy. Can some one please help. java.security.AccessControlException: Access denied (java.lang.RuntimePermission createClassLoader) at java.security.AccessController.checkPermission(AccessController.java:108) at java.lang.SecurityManager.checkPermission(SecurityManager.java:558) at com.ibm.ws.security.core.SecurityManager.checkPermission(SecurityManager.java:212) at java.lang.SecurityManager.checkCreateClassLoader(SecurityManager.java:620) at java.lang.ClassLoader.<init>(ClassLoader.java:136) at org.drools.rule.CompositeClassLoader.<init>(CompositeClassLoader.java:16) at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:249) at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:142) at org.drools.builder.impl.KnowledgeBuilderProviderImpl.newKnowledgeBuilder(KnowledgeBuilderProviderImpl.java:29) at org.drools.builder.KnowledgeBuilderFactory.newKnowledgeBuilder(KnowledgeBuilderFactory.java:29) Thanks, Gaurav -- View this message in context: http://n3.nabble.com/Urgent-Runtime-error-java-lang-RuntimePermission-cre...
