Sun Java Wireless Toolkit 2.5.2_01 for CLDC Download

WTK 2.5.2 has been integrated into Java ME SDK 3.0. While you are welcome to use WTK 2.5.2, we highly recommend the newer feature-rich Java ME SDK 3.0.

 

The Sun Java Wireless Toolkit (formerly known as J2ME Wireless Toolkit) is a set of tools for creating Java applications that run on devices compliant with the Java Technology for the Wireless Industry (JTWI, JSR 185) specification and the Mobile Service Architecture (MSA, JSR 248) specification. It consists of build tools, utilities, and a device emulator.

What's in WTK 2.5.2

The Sun Java Wireless Toolkit implements impressive capabilities which are exposed through standard APIs. The APIs are defined through the Java Community Process (JCP):

  • Mobile Service Architecture (JSR 248)
  • Java Technology for the Wireless Industry (JTWI) (JSR 185)
  • Connected Limited Device Configuration (CLDC) 1.1 (JSR 139)
  • Mobile Information Device Profile (MIDP) 2.0 (JSR 118)
  • PDA Optional Packages for the J2ME Platform (JSR 75)
  • Java APIs for Bluetooth (JSR 82)
  • Mobile Media API (MMAPI) (JSR 135)
  • J2ME Web Services Specification (JSR 172)
  • Security and Trust Services API for J2ME (JSR 177)
  • Location API for J2ME (JSR 179)
  • SIP API for J2ME (JSR 180)
  • Mobile 3D Graphics API for J2ME (JSR 184)
  • Wireless Messaging API (WMA) 2.0 (JSR 205)
  • Content Handler API (JSR 211)
  • Scalable 2D Vector Graphics API for J2ME (JSR 226)
  • Payment API (JSR 229)
  • Advanced Multimedia Supplements (JSR 234)
  • Mobile Internationalization API (JSR 238)
  • Java Binding for the OpenGL(R) ES API (JSR 239)

The Sun Java Wireless Toolkit 2.5.2 includes all of the advanced development features found in version 2.2, 2.5, 2.5.1 such as MIDlet signing, certificate management, integrated over-the-air (OTA) emulation, push registry emulation, and more.

This release of the Sun Java Wireless Toolkit includes Nokia's Scalable Network Application Package (SNAP) Mobile API and the SNAP Mobile Sample Application as part of the toolkit's External API feature. SNAP Mobile is a combination of client software and server infrastructure that supports the creation of networked, community-enabled multiplayer games. For more information, consult the SNAP Mobile web site at http://www.forum.nokia.com/snapmobile. The Emulation Environment, development resources and support for SNAP Mobile are available from http://www.forum.nokia.com/games/snapmobile. Please see SNAP Mobile Emulation Environment Installation for further information.

Note: Sun Java Wireless Toolkit Version 2.5.2_01 for CLDC is a Security Update that corrects vulnerabilities that might allow an untrusted application to execute arbitrary code. The vulnerability can only be exploited if you obtain a malicious program and run it in an earlier version of the toolkit. The only change in version 2.5.2_01 is the security update, so references to version 2.5.2 on this page and in the documentation correctly identify the most recent feature release. The version 2.5.2 documentation (included in the download) remains valid.
