URLs

A Uniform Resource Locators (URLs) is a string that specifies the location of a resource on the World Wide Web. The specification of a URL's syntax and semantics are described in RFC 1738. In summary, a URL's syntax is:
scheme : scheme-specific-parts
where scheme identifies the URL's type. For example, the following is a URL for the ldap scheme:
ldap://localhost:389/cn=Ted Geisel, ou=People, o=JNDITutorial
URL strings are used in several places in the JNDI. Their usage can be categorized into two groups: as names, and as address data. They are used as names in the following ways:

As names to the initial context
As names returned by naming enumerations
They are used as address data in the following ways:

As references for federation
As data for configuration
This lesson describes these uses of URL strings in the JNDI. See the Referral lesson for descriptions and examples of how URL strings are used as LDAP referrals.
