A Client Company implements an archive-downloading package. It downloads presentation archives from its providers, Server Companies 1 and 2. Server Company 1 archive includes Enterprise JavaBean client code; Server Company 2 includes Java Message Service (JMS) client code. The archives are either JAR files or Web Archive (WAR) files. Since Client Company downloads its archives through the Internet: It wants to be sure downloaded archives can be sent only by its identified providers. It wants to be aware of the security requirements of its providers. For instance, does a downloaded archive need to write or remove files? The first article in this series (JDJ, Vol. 6, issue 1) described how to download servlets and JSP archives like applets. Part 2 (JDJ, Vol. 6, issue 2) showed how to administrate these presentation archives remotely, in particular to force a refresh ... (more)

A Practical Solution for the Deployment of JavaServer Pages Part 2 of 3

Last month in JDJ (Vol. 6, issue 1) we looked at the advantages of downloading servlets and JavaServer Pages (JSP) from a repository, for example, the same way a browser downloads applets. We described a simple implementation of this concept based on a service servlet and a custom class loader. This tool, named JSPservlet, handled servlets and JSP packaged in JAR archives to minimize the number of connections and transfers required. This month I'll show you how to publish an archive, update it or force its download through a JSPupdate servlet, and extend the solution to handle r... (more)

A Practical Solution for the Deployment of JavaServer Pages

Sometimes it's worthwhile to go back and visit your former projects. It certainly was for me - using presentation as a commodity to be deployed according to network configuration is the concept that resulted from my visit. The original assignment was to reduce the operating costs of a large banking agency network. How could this be achieved with a network of 23,000 personal computers scattered over 2,000 sites connected by a frame relay with a guaranteed bandwidth of 32Kb? We selected an intranet solution that radically reduced PC client/server applications to a single local pro... (more)
