In jboss-web.xml, I have added, <jboss-web> <class-loading java2ClassLoadingCompliance="false"> <loader-repository> com.example:loader=arvhice-name <loader-repository-config>java2ParentDelegation=false</loader-repository-config> </loader-repository> </class-loading> </jboss-web> and I have set UseJBossWebLoader to false. I have ojdbc14.jar in my WEB-INF/lib but still it says apparently wrong driver. If I copy the jar to server/lib it works but I want it to be in my war.
