    Can't lookup cache service through JNDI

    Chris Perfect Newbie

      I have deployed JBossCache 1.2.1 via a treecache-service.xml in my deploy directoty (JBoss 3.2.6) but I always get NameNotFoundException when I try and look it up in my web app. The JMX Console and the log are telling me the cache is deployed properly.

      the lookup code (hard coded jndi name for testing):
      Context ctx = new InitialContext();
      TreeCache cache = (org.jboss.cache.TreeCache) ctx.lookup("java:MyTreeCache");

      Similar code works for looking up datasources I have deployed using a *-ds.xml in the same webapp. Has anybody any idea why this doesn't work?
