- Atmel Corporation "Documents for AT32AP7000" - PDF document “AVR32 Java Technical Reference Manual Complete”. Obviously Java on AVR32 is “mature”, from point of view of Atmel
.
ST Hardware for IS2T Runtimes
- STMicroelectronics N.V. "Innovative Development Platform from STMicroelectronics Brings Smartphone Style to Simple Appliances", 2013-01-21 - “STM32Java is priced at $2600 per seat per year”.
- I was told by ST staff members: STM32 MCUs with a final “U” are intended for sampling and development, while the “J” types are for production.
- STM32F205VGT6J, STM32F205ZGT6J, STM32F207IGH6J, STM32F207VGT6J, STM32F207ZGT6J.
- STM32F405VGT6J, STM32F405ZGT6J, STM32F407IGH6J, STM32F407VGT6J, STM32F407ZGT6J.
- STM32F401CBU6, STM32F401CCU6, STM32F401CCU6U, STM32F401CCY6UTR, STM32F401CDU6, STM32F401CEU6, STM32F401RCT6U, STM32F401RET6U, STM32F401VCH6U, STM32F401VCT6U, STM32F401VET6U, STM32F405RGT6U, STM32F407IGH6U, STM32F407IGT6U STM32F407VGT6U, STM32F407ZGT6U, STM32F417IGH6U, STM32F427IIH6U, STM32F429IIH6U, STM32F429IIT6U, STM32F429VIT6U, STM32F429ZIT6U, STM32F437IIH6U, STM32F439IIH6U, STM32F439IIT6U, STM32F439NIH6U, STM32F439VIT6U, STM32F439ZIT6U.
- ST Evaluation Kits.
- STM32Java - STM32 Embedded Java Website - “3 months time limited evaluation version. No production rights”.
- STMicroelectronics N.V. "STM3220G-JAVA. STM32 F2 series Java evaluation kit" with STM32F207IGH6 MCU.
- Mauser "STMicroelectronics STM32 Series Java Evaluation Kits" - “The kit is composed of the STM3220G-EVAL evaluation board and a DVD ROM which contains an evaluation version of the STM32Java software development kit based on MicroEJ. MicroEJ is based on the Eclipse IDE and provides extended features for using Java in embedded systems to design and deploy embedded Java applications, simulate embedded Java applications on PCs and perform automated tests. The main limitations of the evaluation version are 3 months of use from the first launch and 1 hour of runtime”.
Freescale Hardware for IS2T Runtimes
-
- “With JAKARTA you will able to evaluate various hardware technologies relevant to HMI, including the exciting IS2T MicroEJ Embedded User Interface, the first Java virtual machine for the Freescale Kinetis L (ARM Cortex-M0+). Lightweight and low cost!”.
- “With around 28kB of non-volatile memory, IS2T MicroEJ for Freescale Kinetis L uses only 11% of the Freescale KL46 flash memory (and the MCU cost) for the huge advantage that Java can bring to your next project. JARKATA also provides various hardware technologies like OLED display, haptic feedback, sensors and many more”.

- There is a “Java ME 8 JVM” by Orcacle for the ST32F4 Discovery board. Unfortunately there is no official download of the JVM anymore. Please tell me, if you got the free software, still have it and are willing to share it with me:-)!
- In 2015-10, I was told by the Oracle product management, that the binary release must be withdrawn “due to the license limitations of a partner”. Oracle has no right to distribute the binary release anymore, to anybody, not even internally to staff members.
- Terrence Barr - Across the Universe "Java ME 8 Early Access release: Try it out!", 2013-09-21 - “Java ME 8 Early Access is available now for the following developer boards: Raspberry Pi Model B (ARM11/Linux), ST Microelectronics STM32F4DISCOVERY (ARM Cortex-M4)”.
Some other Boards
- BubbleBoard, based on Cinterion base by Gemalto, supported by Java ME 3, equipped with Arduino compatible IO's as well as a modem.

Native Interfaces for Java
Java Native Interface ( JNI )
The Interface
- Oracle / SUN.
- Oracle "Java Native Interface" of JDK 7.
- Oracle "Java Native Interface Tips" ( “JNI FAQ” ).
- Book Sheng Liang "Java Native Interface: Programmer's Guide and Specification" - free PDF & HTML download #.
A special Suggestion how to debug JNI Applications
How to debug JNI Applications
- If you want to develop JNI applications with Windows DLLs, on Linux:
- The Java classloader takes notice, that the DLLs are not available and so won´t load the application.
- If you mock the DLLs by ASM / BLC, by overwriting the Java Interfaces from “native public” to “public”, an empty body is kept, which the Java classloader may load
.
