SavaJe XE

Description: Fully featured Native Java OS
Notes: PocketPC port was recently sold to  recently sold to MochaWorks who have not released anything yet. Early versions demonstrated a Java OS with neat UI, MP3 player, organizer etc with support for PC card 802.11, CF & PC card Ethernet and MODEM.

Sun PersonalJava

Description: Sun抯 own Java runtime environment for handhelds.
Notes: This product has been discontinued, though a CE 2.11 version is available from Sun’s EOL(End Of Life) site. Fairly fast and well implemented, AWT components look same as those on desktop machines, a useful console window is provided for debugging etc, is also very well documented and supported. Only problem is that it does not manage memory or threads very well, command line options can be used to help slightly (by assigning more memory), though many simultaneous threads and large data structures always cause a crash.

Blackdown J2RE

 

Description: Blackdown’s Java 2 JDK for Linux ported to ARM

Notes: Requires Linux on iPAQ

URL: http://www.blackdown.org/

 

Jeode

 

Description: Well featured PocketPC VM

Notes: Comes free with some Compaq iPAQs (this version is limited to iPAQ devices only). Also available for Dell PDA’s from Handango. The only other way I found to purchase Jeode is to join their educational institution program, which seems very expensive.

NSICOM CrEme

 

Description: Quick, good support, very polished – an excellent product
Notes – Handles memory far better than Sun’s Personal Java, also faster. Supports Truffle and Tiny AWT AWT components which all work perfectly, it is provided with a useful launcher application.  Provides various useful command line switches (such as to remove WinCE task bar), comm support fully implemented & works perfectly (also tested with iButtons). Overall a very solid VM implementation.

Notes: Commercial product, though Linux evaluation version are available for download

SuperWaba VM

 

Description: Another free JVM based on the Waba API, with support for both PalmOS and PocketPC with almost 100% source compatibility between the two platforms.

Notes: A lot of good GUI tools and libraries to extend the API to the platform.
