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)

Future Proof Your Web Application Using Clustered Cache Services

Today's web developers have a lot of choices when it comes to web application platforms. Among them, Java EE has always stood out as a "scalable" solution -- it may not be the easiest platform to prototype a web site, but it protects your software investment over longer terms. For instance, Java EE is a cross platform solution supported by many vendors. That means you can choose from man... (more)

"Mobility is More than J2ME," Says Michael Yuan

I was reading Glen Cordrey's last J2ME column in this month's issue of JDJ. Glen mentions that, as the J2ME market has not matured with enough jobs, he is going back to J2EE and try to work on mobility integration issues in enterprise projects. I complete agree with him and in fact, this is the point I have always advocated in my writings. My keyword for mobility has always been "end-to-... (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)

Is Mobile Java a Reality?

"Java on mobile phones" has been the hottest topic at the JavaOne conference for the past several years. This year was no exception and a large part of the show floor was designated as the "Wireless Village." With tens of billions dollars' worth of Java phones and related services sold every year, Sun and many others are clearly making money. However, most JavaOne attendees I met were en... (more)
