[jboss-user] [EJB] - caching the jndi call
hi,
i got my ejb's up and running
in my web project i call them like that
| TraxManager TraxManager =
(TraxManager)context.lookup("TraxService/remote");
|
in my web project i implement this call in each of managed beans, which no an optimal
solution
so i try to do a generic method ==>
| import java.util.Collections;
| import java.util.HashMap;
| import java.util.Map;
| import java.util.Properties;
|
| import javax.ejb.EJBHome;
| import javax.naming.Context;
| import javax.naming.InitialContext;
| import javax.naming.NamingException;
|
| public class EJBHomeFactory {
|
| private static Map<String, Object> cache=Collections.synchronizedMap(new
HashMap());; //used to hold references to EJBHomes/JMS Resources for re-use
|
|
| private EJBHomeFactory() throws ServiceLocatorException {
| try {
| //THIS DOESN'T GET EXECUTED :(
| cache = Collections.synchronizedMap(new HashMap());
| } catch (Exception e) {
| throw new ServiceLocatorException(e);
| }
| }
|
|
| public static Object lookupObject(String jndiName) throws ServiceLocatorException {
| EJBHome home = null;
| Context context = null;
|
| try {
| if (cache.containsKey((Object)jndiName)) {
| return cache.get(jndiName);
| } else {
| Properties props = new Properties();
|
props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
| props.setProperty("java.naming.provider.url",
"jnp://192.168.1.201:1099");
| props.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming");
| props.setProperty("jnp.socket.Factory",
"org.jnp.interfaces.TimedSocketFactory");
| context = new InitialContext(props);
| //Object obj = context.lookup(jndiName);
| cache.put(jndiName, context.lookup(jndiName));
| }
| } catch (NamingException ne) {
| throw new ServiceLocatorException(ne);
| } catch (Exception e) {
| throw new ServiceLocatorException(e);
| }
| return cache.get(jndiName);
|
| }
|
|
|
| public Map<String, Object> getCache() {
| return cache;
| }
|
|
|
| public void setCache(Map<String, Object> cache) {
| EJBHomeFactory.cache = cache;
| }
|
|
| }
|
|
|
i test with 2 class, so that the first one , fill the map and the second should find a a
map with the key of the jndi name , but it never found it,
| if (cache.containsKey((Object)jndiName)) {
| return cache.get(jndiName);
| }
is never executed
and thanks
