Hi, My J2EE application uses DROOLS 3.0.6 libraries for rules and runs on SUN JES 2005 Q4 server. I am getting the exception : Caused by: java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader) Currently I have granted RunTimePermission for "createClassLoader" in the global area (i.e for all jars) of server.policy and the application works fine. But I want to specify the permissions for "only" drools and the dependent jars. Please let me know the list of jars which requires createClassLoader - RunTimePermission . The complete stack trace is given below: Regards Smitha -------------------------------------------------------------------------------------------------------------- (java.lang.RuntimePermission createClassLoader) at com.abc.rules.jboss.DroolsContainer.buildRuleBase(DroolsContainer.java:217) at com.abc.rules.jboss.DroolsContainer.init(DroolsContainer.java:91) at com.abc.rules.EnvironmentManager.initContainer(EnvironmentManager.java:252) at com.abc.rules.EnvironmentManager.init(EnvironmentManager.java:158) at com.abc.rules.PDMImpl.ejbCreate(PDMImpl.java:224) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at com.sun.ejb.containers.StatelessSessionContainer.createStatelessEJB(StatelessSessionContainer.java:4 10) at com.sun.ejb.containers.StatelessSessionContainer.access$100(StatelessSessionContainer.java:75) at com.sun.ejb.containers.StatelessSessionContainer$SessionContextFactory.create(StatelessSessionContai ner.java:597) at com.sun.ejb.containers.util.pool.NonBlockingPool.getObject(NonBlockingPool.java:168) at com.sun.ejb.containers.StatelessSessionContainer._getContext(StatelessSessionContainer.java:359) at com.sun.ejb.containers.BaseContainer.getContext(BaseContainer.java:1072) at com.sun.ejb.containers.BaseContainer.preInvoke(BaseContainer.java:772) at com.sun.ejb.containers.EJBLocalObjectInvocationHandler.invoke(EJBLocalObjectInvocationHandler.java:1 26) at com.abc.sms.SendSmsImpl.sendSms(SendSmsImpl.java:654) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at com.sun.enterprise.security.SecurityUtil$2.run(SecurityUtil.java:153) at java.security.AccessController.doPrivileged(Native Method) at com.sun.enterprise.security.application.EJBSecurityManager.doAsPrivileged(EJBSecurityManager.java:95 0) at com.sun.enterprise.security.SecurityUtil.invoke(SecurityUtil.java:158) at com.sun.ejb.containers.WebServiceInvocationHandler.invoke(WebServiceInvocationHandler.java:116) at $Proxy34.sendSms(Unknown Source) at com.sun.enterprise.webservice.EjbWebServiceDispatcher.handlePost(EjbWebServiceDispatcher.java:140) at com.sun.enterprise.webservice.EjbWebServiceDispatcher.invoke(EjbWebServiceDispatcher.java:79) at com.sun.enterprise.webservice.EjbWebServiceValve.dispatchToEjbEndpoint(EjbWebServiceValve.java:187) at com.sun.enterprise.webservice.EjbWebServiceValve.invoke(EjbWebServiceValve.java:131) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:542) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:933) at com.sun.enterprise.web.connector.httpservice.HttpServiceProcessor.process(HttpServiceProcessor.java: 226) at com.sun.enterprise.web.HttpServiceWebContainer.service(HttpServiceWebContainer.java:2071) Caused by: java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264) at java.security.AccessController.checkPermission(AccessController.java:427) at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) at java.lang.SecurityManager.checkCreateClassLoader(SecurityManager.java:594) at java.lang.ClassLoader.<init>(ClassLoader.java:201) at org.drools.rule.PackageCompilationData$PackageClassLoader.<init>(Unknown Source) at org.drools.rule.PackageCompilationData.init(Unknown Source) at org.drools.rule.PackageCompilationData.<init>(Unknown Source) at org.drools.rule.Package.<init>(Unknown Source) at org.drools.compiler.PackageBuilder.newPackage(Unknown Source) at org.drools.compiler.PackageBuilder.addPackage(Unknown Source) at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source) at com.abc.rules.jboss.DroolsContainer.buildRuleBase(DroolsContainer.java:204) ... 41 more --------------------------------- Building a website is a piece of cake.
