Help needed to figure out URL and username for the LDAP server

Question

Given that LDAP directory parameters as follows, how can i identify the exact parameters to be used in my LDAP service access Java code. Im using JNDI to access a LDAP server given by an Ip address (say, 10.1.1.20) and the port number (say, 389)
Given: -D "cn=mycn,ou=mystaff,o=myorg,dc=test,dc=my,dc=org" -w secret
Heres my sample Java code
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "<URL>");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "<PRINCIPAL>");
env.put(Context.SECURITY_CREDENTIALS, "secret");
ctx = new InitialDirContext(env);
SearchControls controls = new SearchControls();
controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
results = ctx.search("ou=mystaff,o=myorg", null);Could any one please help me to recognize what will be the values to be comes to URL, and PRINCIPAL , so that i can search all the objects inside "ou"
Note: Actually i tried several times, bt i was getting "Invalid Credentials" exception.. i doubt that is because the URL or the user name i gave was not syntactically correct. Thats y i need to verify with you all.
Thanks in advance
