I have a problem with JNDI when moving from Weblogic 6 to JBoss 4.2.0.GA. I have a class which is bound to a JNDI name (Global), but when I do a lookup I always seem to get a copy rather than a reference. This code had previously worked ok on Weblogic. public class RuleCacheHolder implements Serializable // implements T3StartupDef, IRuleCacheHolder { /** * */ private static final long serialVersionUID = 2938516269249036614L; private String _className = this.getClass().getName(); protected boolean noConnection = false; private String _cacheName; private String _cacheType; private String _types[]; private Hashtable cache = new Hashtable(); private static final String jndiName = "CACHE_HOLDER_"; public RuleCacheHolder(String cacheName, String cacheType, String types[]) { setCacheName(cacheName); setCacheType(cacheType); setTypes(types); try { new InitialContext().bind(jndiName + cacheName, this); // initialiseCache(); // WebLogger.trace(_className+" CACHE_HOLDER_"+getCacheName()+" // CREATED..."); } catch (NamingException ne) { ne.printStackTrace(); } } After creation I populate the cache hashtable from a different class, however when a subsequent lookup is done the cache hashtable is empty. I am using a jndi prop file and have tried changing the CallByValue setting in jboss-service.xml. There are no errors or exceptions in the lookup. I have scoured the various sites to no avail so any help would be greatly appreciated. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4101016#...
