Written for developers to work, this book not only shows the elements of Java toolkit but also the strategies and techniques for creating good Internet directories. There is a good balance in this text between the background and theory of Internet directories and examples of many useful programs that show LDAP and Java in action. (This capability allows users to access their personal settings from anywhere on a network.) Materials other prominent include security and authentication, including some good detail on signing JAR files for both Netscape and Internet Explorer Web browser.
