Can't lookup cache service through JNDI
pei Mar 10, 2005 11:23 PMI 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.
treecache-service.xml:

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?
