There are three ways to provide InitialContext settings:
1) Through System properties
2) By adding a file called jndi.properties to classpath which contains
these settings
3) By using the InitialContext(Properties) constructor
In case 3) you can either
a) hardcode (which is done by most examples. Terrible)
b) softcode by placing properties in a properties file
For 3b (flexible yet dynamic) I suggest the following. Place JNDI
properties for server X that you want to connect to in x.properties.
Then load them in your program by doing:
Properties env = new Properties();
env.load(getClass().getResourceAsStream("/x.properties"));
Context xContext = new InitialContext(env);
This will allow you to keep settings in text files, and still be able to
direct your client to many servers (simply have one properties file per
server you want to connect to).
If you only have one server that your client should connect to, use 1 or
2. And 1) can also be done with the above code:
System.getProperties().load(getClass().getResourceAsStream("/system.properties"));
So, by placing your additional system properties in "system.properties"
you avoid having to use the -D JVM flag or hardcoding them.
