Hi All, I'm using Tomcat 5.0 version. I downloaded the Blog with Roller installation and deployed it in Tomcat. I was able to browse and use the Roller Blog Application successfully. The Roller installation has specific configuration steps for Tomcat. But now I want to integrate Roller Blog with Jboss Portal 2.4 version. I got the below exception: --------------------------------------------------------------------------------------org.jboss.deployment.DeploymentInfo@1ec75adc { url=file:/C:/jboss-portal-2.4.0/server/default/deploy/blog.war } deployer: MBeanProxyExt[jboss.web:service=WebServer] status: Deployment FAILED reason: Error during deploy; - nested throwable: (javax.naming.NamingException: resource-ref: jdbc/rollerdb has no valid JNDI binding.
