在jndi.properties中声明变量

Question

I want to know if it is possible to declare à custom int or integer in jndi.properties.

I'm doing a JMS program. And I want to "give" easly an int to the program.

I tried to find by myself, but I can't find anything interesting.

So can I or is jndi really formated to be use only by strict rules.

What I want to do in jndi.propreties:

#number of threads accepted
int.maxThreads = 3 

#queue.[jndiName] = [physicalName]
queue.MyQueue = MyQueue2

Then in java :

int maxThreadsTemp = (int) ctx.lookup("maxThreads");

I tryed but failed. I get the normal : "javax.naming.NameNotFoundException: maxThreads"

So did I declared it wrong or is it just impossible to do so ? Thanks in advance.

*Edit : I use ActiveMQ and for JNDI I used this url to do it : http://activemq.apache.org/jndi-support.html

Answer 1

I found the answer : What I did was to forget the methode lookup(...)

ctx = new InitialContext(...);
int maxThreadsTemp = (int) ctx.lookup("maxThreads");

Instead I used a hashtable (much simpler):

ctx = new InitialContext(...);
Hashtable<?, ?> environment =  ctx.getEnvironment();
            String nbrThread = (String)  environment.get("maxThreads");

And in jndi.properties : maxThreads = 5 (thx to @Claus Ibsen)
