Deploy code servers in Jini systems Jini is a simple architecture for distributed systems, but developers often find that deploying a Jini system, and running multiple HTTP servers in particular, can be challenging. This article describes several solutions to this problem, and covers the advantages and disadvantages of each solution, such as scripts, embedded HTTP servers, all-in-one Jini systems, and enterprise-class HTTP servers.   |

Get smart with proxies and RMI RMI enables developers to either get a remote reference to a distributed object, in which all method calls are forwarded to the server object, or get a copy of the remote object and invoke on it locally. You can combine these approaches in a way that is transparent to the client code... |

Mix protocols transparently in Web applications To maintain the security of sensitive data as it travels over the Internet to or from the browser, Web applications often rely on Secure Sockets Layer. The secure Webpages and processes that transmit sensitive data utilize HTTP over SSL (HTTPS) rather than the usual HTTP. Integrating SSL into a Web application should prove seamless and simple to implement as well as maintain. This article explores typical SSL implementations and develops an SSL solution using the J2EE servlet redirect mechanism to protect sensitive data transmission. It also develops an overall solution combining JavaServer Pages custom tags and an application-specific servlet base class. |

Take control of the servlet environment, Part 1 The ever-popular servlet cleanly and simply develops and deploys Web-based applications. However, although Java is platform independent, the Web as a whole is not. The language and the servlet API do not provide such niceties as optional session-persistence schemas (i.e., store in memory, in a database, or in a cookie), and they don't easily accommodate ad hoc solutions to shortcomings in cookie handling. To handle such issues, Thomas Davis and Craig Walker have developed an unobtrusive framework, an invisible layer between your servlets and the servlet engine, that gives you greater control over the environment. |
