Java Technology for the Wireless Industry (JTWI), JSR 185

The Java Technology for the Wireless Industry (JTWI) specification defines the industry-standard platform for the next generation of Java technology-enabled mobile phones. JTWI is defined through the Java Community Process (JCP) as JSR 185 by an expert group of leading mobile device manufacturers, wireless carriers, and software vendors. It specifies the technologies that must be included in all JTWI-compliant devices, to minimize API fragmentation and broaden the substantial base of applications already developed for mobile phones.   »  Read More

JTWI Technology

Each Java technology has an API specification, a reference implementation (RI), and a technology compatibility kit (TCK) associated to it. Read the open letter from the JSR 185 expert group members to the community to learn more about the availability of JTWI and related technologies.


Reference Implementation:
A binary copy of the JTWI RI is available on demand by sending an e-mail to Application developers who want to test their application against the RI should instead download the J2ME Wireless Toolkit 2.1, which includes additional tools and utilities targeted at the development of JTWI-compliant applications.

Technology Compatibility Kit:
The JTWI TCK can be licensed from Sun to certify a JTWI implementation on a particular platform. For more information about licensing terms, please contact Sun's Java Partner Engineering group.
