• To Java Or Not To Java? A few months ago, Microsoft announced to fully drop Java (we wrote about that in JavaNews). Now Microsoft announces a "Java-like" .NET programming language called J#.NET (pronounced "Jay-Sharp Dot Net"). Just to make it easier for companies to move existing Java code onto .NET. Do Java developers care? Is it a necessary tool for the current state of technology? Read about that in

• Java enabled devices for GSM networks. Finally things are starting to fall into place. This month I got a Siemens SL 45i as well as a Motorola Accompli 008 device on my desk! Both can run J2ME MIDlets. The Siemens device is very small and compact, but only supports GSM-Data. If you have an SL42 or SL45, then you can turn it into a full-fledged 45i through a pure software upgrade. Contact me if you are interested in that. The Motorola is more of a communicator-type of device, with PDA capabilities. The Accompli has more memory than the SL45i, and runs on GPRS. For some interesting mobile Java resources, check out

• Superior application management with JMX. JMX (Java Management Extensions) is an extensible application management framework. With JMX you can build Java server applications that can be managed through protocols such as SNMP or CMIP, and through network management tools such as Tivoli™ or Patrol™.
  Many J2EE vendors, such as JBoss, Enhydra and WebLogic, are using it. The following is an introductory article to JMX.

• The battle over Web services. Web services are getting a lot of attention (and hype!) these days. Web services are touted as "the solution" for building open and vendor-neutral services, which can be called over the Internet using HTTP as transport protocol. Though Web services promise platform independence, vendors, including Sun with J2EE, strive to lock customers into proprietary Web services platform solutions.

• Garnter says Web services are coming soon. Microsoft and Sun are betting heavily on Web services and on SOAP (Simple Object Access Protocol). The way businesses and consumers use software "will change dramatically" as component-based Web services start to become available in the coming months and years.
