Dear All, Firstly, before deploying the Drools guvnor in weblogic11g , I set the repository configuration in components.xml.below is the path i mentioned for repositoryConfiguration <component name="repositoryConfiguration"> <property name="homeDirectory">E:/GuvnorRepo/</property> Deployed the Drools guvnor in weblogic11g , and in E drive GuvnorRepo folder has created with 3 sub folders workspaces,repository,version and repository.xml. Now i updated the repository.xml for changing the database from derby to oracle. Below are the changes <PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.OraclePersistenceManage r"> <param name="driver" value="oracle.jdbc.driver.OracleDriver"/> <param name="url" value="jdbc:oracle:thin:@rsa10gserver:1525:ifpub34"/> <param name="user" value="drools_repository"/> <param name="password" value="drools_repository"/> <param name="schema" value="oracle"/> <param name="schemaObjectPrefix" value="version_"/> <param name="tableSpace" value=""/> <param name="errorHandling" value=""/> </PersistenceManager> Now i restarted the weblogic11g and it successfully deployed and entered into the login page and but i could not see any rules in the left navigation page. Is there any other procedure rather than what I have done? Whether I should import/export new repository.xml ? Please help me regarding this.
