15. Java ME Realities...
Java ME Realities
Run Once…Test Everywhere
• Java ME is a collection of Java standards
which are liberally interpreted by device and
VM manufacturers
• There are many optional aspects of the Java
ME standards which don’t get supported
• Not all Java ME devices support MIDP
• Not all devices support Java ME
• Detailed specs for devices are difficult and
sometimes impossible to find

16. Java ME Realities...
Java ME Realities
Run Once…Test Everywhere
• Applications must be tested on every device
you expect to support
• Devices can be grouped into families to
minimize the number of devices you need
to test on
• There are few reliable resources to help you
group devices - Experience, Trial and Error
are your best tools
• On-device testing cannot be automated
cheaply so plan for a person to do this
