Sun, NTT DoCoMo plan new cellular Java platform

Star project to update DoCoMo's Java platform

So part of the Star project work is to consider the runtime environment in which the Java platform operates. Most phones today use the Connected Limited Device Configuration (CLDC), but some more advanced handsets such as those sold in Japan could benefit from the more capable Connected Device Configuration (CDC), Natsuno said.

CLDC's limitations are becoming apparent in some of today's powerful phones, but the technology is still fine for the vast majority of handsets, said Eric Chu, senior director of Java Micro Edition at Sun.

"If you chose the CDC solution, it's not right for 80 percent to 90 percent of the market. CLDC is the right platform, but on smart phones it is a little anemic," he said.

In working with DoCoMo, Sun isn't taking sides or promoting DoCoMo's platform over standards worked out jointly by carriers as part of the Java Community Process, said Chu. Rather, Sun sees it as an opportunity to work JCP-developed technology into DoCoMo's new Java platform, he said.

DoCoMo and Sun would not say how long it might take to develop the new platform, but Natsuno said the two years it took to develop DoJa could serve as a guide.

The platform may be available for use by other carriers when it is complete, which could be a big boon for application developers.

"We are not intending to [restrict] this only for DoCoMo," Natsuno said.
