Java community to nail mobile phone spec

It's called JSR 185, for all you Java cellphone aficionados


ComputerWire: IT Industry Intelligence

Java community members are taking another stab at Java for small devices, with plans for a specification designed specifically for ISVs targeting cell phones.

Java Community Process (JCP) members are pushing Java Specification Request (JSR) 185, which rounds up a number of existing Java APIs and technologies in an architecture designed only for cell phones. A test kit is also planned to ensure compatibility of vendors' implementations.

Developers targeting handsets can currently choose from a number of JCP-ratified technologies to build applications based on the Java 2 Micro Edition (J2ME) specification

J2ME, though, has been modified over recent years to include optional enhancements such as Mobile Device Information Profile (MIDP), Connected Limited Device Configuration (CLDC) and Connected Device Configuration (CDC) among other extensions.

Any combination of these technologies can be used on a number of small footprint devices and equipment with limited memory or power sources from cell phones to personal digital assistants (PDAs) and set-top-boxes.

However, JCP members believe ISVs who specifically target cell phones would be better served by a specification that acts as a reference for their needs and that excludes PDAs and set-top-boxes, for example. JSR 185 is designed to outline a core set of J2ME APIs for an application that is capable of running across any handset manufacturers' device.

JSR 185 is expected to include CLDC, CLDC 1.0, CDC, MIDP, MIDP 2.0, Wireless Messaging API and Mobile Media API.

Those backing JSR 185 include JCP members Motorola Corp, Nokia Corp, Sony Ericsson Mobile Communications AB and NTT DoCoMo Inc with Sun Microsystems Inc.

  • Stolen university credentials up for sale by Russian crooks, FBI warns
    Forget dark-web souks, thousands of these are already being traded on public bazaars

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.

  • Big Tech loves talking up privacy – while trying to kill privacy legislation
    Study claims Amazon, Apple, Google, Meta, Microsoft work to derail data rules

    Amazon, Apple, Google, Meta, and Microsoft often support privacy in public statements, but behind the scenes they've been working through some common organizations to weaken or kill privacy legislation in US states.

    That's according to a report this week from news non-profit The Markup, which said the corporations hire lobbyists from the same few groups and law firms to defang or drown state privacy bills.

    The report examined 31 states when state legislatures were considering privacy legislation and identified 445 lobbyists and lobbying firms working on behalf of Amazon, Apple, Google, Meta, and Microsoft, along with industry groups like TechNet and the State Privacy and Security Coalition.

  • SEC probes Musk for not properly disclosing Twitter stake
    Meanwhile, social network's board rejects resignation of one its directors

    America's financial watchdog is investigating whether Elon Musk adequately disclosed his purchase of Twitter shares last month, just as his bid to take over the social media company hangs in the balance. 

    A letter [PDF] from the SEC addressed to the tech billionaire said he "[did] not appear" to have filed the proper form detailing his 9.2 percent stake in Twitter "required 10 days from the date of acquisition," and asked him to provide more information. Musk's shares made him one of Twitter's largest shareholders. The letter is dated April 4, and was shared this week by the regulator.

    Musk quickly moved to try and buy the whole company outright in a deal initially worth over $44 billion. Musk sold a chunk of his shares in Tesla worth $8.4 billion and bagged another $7.14 billion from investors to help finance the $21 billion he promised to put forward for the deal. The remaining $25.5 billion bill was secured via debt financing by Morgan Stanley, Bank of America, Barclays, and others. But the takeover is not going smoothly.
