As demonstrated in this article, XML and tools such as the kXML parser will allow mobile computing technologies such as J2ME to coexist and interoperate with existing Web services and enterprise applications. If you're familiar with the Open Source Enhydra Java/XML application server, expect to see kXML become a complementary technology used with Enhydra for J2ME applications. (Enhydra already provides support for other wireless technologies, including WAP.) The logical next step for kXML is a SOAP client for J2ME; at the time of this writing, the kSOAP project had just been kicked off by Stefan Haustein. Expect to hear much more about XML and mobile computing technologies such as J2ME as Java devices and Web services become widespread.
