Try java:/comp instead. If that doesn't help, then we'll need more info: - OS: - where you got tomcat from (tomcat.apache.org or third party repackage) - Details of your setup like what's in tomcat's common/lib folder? - Config (relevant parts of server.xml, the webapp's context.xml and WEB-INF/web.xml) - The code used to access JNDI if available:
Links to any docs you used to get you to this point would also be great just in case they are providing bad advice. --David Mikolaj Rydzewski wrote: > Hello everybody, > > I have faced interesting issue recently.
