JVM choices on Windows Mobile

Question

What are the JVM implementations available on Windows Mobile?

Esmertec JBed is the one on my WinMo phone.

Wondering how many other JVM vendors are in this zone. Are there any comparison or benchmarking data available?

Answer 1

JVM Choices for Windows CE in general (including Pocket PC and Windows Mobile):

• CrE-ME
• Mysaifu
• Skelmir CEEJ

If you're looking to have a common code base between WinMo and Symbina, you might also look at Red Five Labs. They have a Symbian runtime that allows you to run COmpact Framework apps, so you could have a CF codebase that works on both. I evaluated the early betas of Red Five's offering, but haven't used it since, so I can't attest to the quality or coverage.

Answer 2

The reason was to have same codebase in WinMo and Symbian.

My personal preference would be to have native solution on both. But that would mean, developing & maintaining two set of code bases. And the management does not prefer that for some reason ;)

Answer 3

There are 2 JVMs for WinMo, Mysaifu for J2SE and IBM WebSphere Everyplace Micro Environment for J2ME.

Answer 4

Prakash, since your goal is to have a common code base between J2ME and WinMo handsets, check out alcheMo. alcheMo is not a JVM, but a fully automated J2ME to native Win32 WinMo porting solution.

Answer 5

Even when running a little late on this question and just for completenes sake: JBlend(micro) is the Java environment for Windows Mobile 6.1 and 6.5 which is used e.g. on HTC devices. It enables for CLDC and MIDP 1.0 and 2.0.

Answer 6

This is not really an answer, but wouldn't it make more sense to target your software at the .NET framework compact edition if you're developing for WinMo?

Answer 7

HP also had a JVM called HP Chai on their old models of Pocket PC

Answer 8

phoneME (java.net page) seems to be a another choice. It is recommended by the LWUIT FAQ.
