Hi, First time post on drools ... I installed Guvnor 5.3.0 on tomcat 6.0.35. When I used the default (Jackrabbit) datastore all worked fine. I next went about trying to change guvnor to use an external RDBMS (Oracle 10g) . I generated a new repository.xml . As per reference manual I used the Repository Configuration Manager to generate a new repository.xml file. However on startup with new repository.xml file, I get the following errors ( console, localhost & catalina). Can anyone shed some light ? thanks in advance, Kevin ###### console - start ###################### 17-Feb-2012 17:14:20 org.apache.catalina.core.AprLifecycleListener init INFO: The APR based Apache Tomcat Native library which allows optimal performanc e in production environments was not found on the java.library.path: C:\Progra~2 \Java\JDK15~1.0_0\bin;.;C:\windows\system32;C:\windows;C:\oracle\product\10.2.0\ client_1\bin;C:\windows\system32;C:\windows;C:\windows\System32\Wbem;C:\windows\ System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ATI Technologies\ATI.ACE \Core-Static;C:\Progra~2\Java\JDK15~1.0_0\bin;C:\apache-ant-1.7.0\bin 17-Feb-2012 17:14:20 org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on http-8080 17-Feb-2012 17:14:20 org.apache.catalina.startup.Catalina load INFO: Initialization processed in 267 ms 17-Feb-2012 17:14:20 org.apache.catalina.core.StandardService start INFO: Starting service Catalina 17-Feb-2012 17:14:20 org.apache.catalina.core.StandardEngine start INFO: Starting Servlet Engine: Apache Tomcat/6.0.35 17-Feb-2012 17:14:20 org.apache.catalina.startup.HostConfig deployDescriptor INFO: Deploying configuration descriptor host-manager.xml 17-Feb-2012 17:14:20 org.apache.catalina.startup.HostConfig deployDescriptor INFO: Deploying configuration descriptor manager.xml 17-Feb-2012 17:14:20 org.apache.catalina.startup.HostConfig deployWAR INFO: Deploying web application archive guvnor.war INFO 17-02 17:14:23,713 (RulesRepositoryConfigurator.java:getInstance:46) Creating an instance of the RulesRepositoryConfigurator. 17-Feb-2012 17:14:24 org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart 17-Feb-2012 17:14:24 org.apache.catalina.core.StandardContext start SEVERE: Context [/guvnor] startup failed due to previous errors INFO 17-02 17:14:24,681 (LoggingHelper.java:info:49) Removing listeners....
