4 Basic JNDI questions I have - please help :-)

Question

Hello JNDI lovers and haters as i feel at the moment :P
Question 1: I get a warning message from my eclipse 3.3:
NamingEnumeration is a raw type. References to generic type NamingEnumeration<T> should be parameterized     LDAP     MainWindow.java     line 133     1184255055215     3297this warning refers to this code line:
NamingEnumeration enm = ctx.search(baseDN,filter,controller);What does that warning mean and how can i make my code proper so i get no warning?
Question 2: I have nowhere in my JNDI book found any hint that i must close an NamingEnumeration instance. So for what is this close() methode and if i have to close an instance of the NamingEnumeration class, when do i have to use it exactly??
Question 3: When i make 2 Context searches like ctx.search(); etc... do i have to use everytime a new ctx instance for every search i do ? like ctx1.search(), for the first search and ctx2.search() for the 2nd search??
Or can i use ONLY 1 instance of a Context class for several searches ? Logically one Context should be enough as i have only one entry point for my ldap tree and its always the same root...
Question 4:
Why does my Duke stars not decrease do i have unlimited of them? well not so a serious question as Adler_Steven deserves them all :D
Would be very pleased guyz if you could help out a JNDI wannabe pro ;-)
EDIT:
i found this information on the sun forum:
javax.naming.NamingEnumeration enum = ctx.search("",satts);
if ( enum.hasMoreElements() ) {
SearchResult firstresult = (SearchResult)enum.nextElement();
attrs = firstresult.getAttributes();
} else {
throw new Exception("No Entries returned");
enum.close(); // without this, ctx.close() did not release the thread
ctx.close();as you can see above the enum is closed and the guy say s if its not closed you might get trouble as the thread gets not released ?? BUT i have seen so many code examples where the ppl dont close the enum instance ?? HOw This ?
