As I have whined many times before, J2ME has been treated like a second class citizen on Symbian smartphones. Most importantly, the Java runtime does not integrate well with the underlying platform. For example, on my Nokia 6600, I cannot access the local PIM database or the photo gallery or the MMC card from Java applications. That severely limits Java's usefulness on those devices since "integration" is key to any successful mobile UI application. Symbian C++ was the only "real" way to develop compelling applications on Series 60 phones. On Nokia 9500, the J2ME File I/O and PIM optional package (JSR 75) was implemented but is only accessible from the CDC/Personal Profile runtime. That is obviously is not good enough. Well, now things finally change! The Nokia 6630 pho... (more)

SOA and Web Services Go Mobile, Nokia-Style

Personally, I think the biggest announcement from JavaOne was that Nokia is building a Service-Oriented Architecture framework on smart mobile phones that could quickly change how an average technology user sees Web services. No, I am not talking about the standard SOAP interfaces between desktop/server applications and telecomm hosted servers (e.g., the MMS messaging server, location serv... (more)

Java Track - Design Patterns And Project Organizational Techniques for "Write Once, Debug Everywhere"

Thursday, February 17, 2005 9:00 A.M. - 9:50 A.M. Unlike the wildly successful server-side Java technology, the true "write once run anywhere" vision has never been achieved for client-side Java. For Java developers offering end-to-end smart client-based SOA solutions, the development process is still "write once, debug everywhere." As the client-side platforms evolve from a handful of P...

Michael Yuan's Java Blog: "Is Ruby Replacing Java? – Not So Fast"

Is Ruby Replacing Java? – Not So Fast Okay, I have heard it all: Ruby On Rails (RoR) is so much cooler and simpler than Java EE. It allows you to write web applications 10X faster. And Ruby has nifty language features we can only dream of in Java. So, Ruby must be replacing Java to become the "next" programming language just as Java "replaced" C++/COBOL and C++ "replaced" Fortran. We... (more)

Annotations, Friend or Foe?

Annotation is a new Java language feature introduced in JDK 5.0. It has quickly become one of the most popular, and yet most controversial, language feature in core Java. New Java frameworks, such as EJB 3.0 and Hibernate 3.0, make extensive use of annotations to eliminate the excessive XML configuration files (a.k.a. the "XML hell" in Java EE). Those annotations significantly reduce the... (more)
