Hello,I need to change at runtime the properties of
the connection, because my database has several users,
I am working with CMP EJB . How could I do it?
Thanks in advanceYou may write your own data source wich you will pass required data (user name) to through some thread oriented storage...
class Store {
static Map cache = new HashMap();
static void setUserName(String userName) {
    cache.put(new Integer(Thread.currentThread.hashCode()), userName);
static String gerUserName() {
    return (String)cache.get(new Integer(Thread.currentThread.hashCode()));
EJB:
setEntityContext(EC ec) {
   Store.setUserName(ec.getCallerPrincipal().getName());
YourDS:
getConnection() {
   return ds.getConnection(Store.getUserName(), ...);
...
