How do I find an implementation for a JSR?

Question

Hi, I am trying to find out about the JSRs implementation specifically for the Mobile and wireless world. I have two questions.

1) Who has implemented these JSRs?

2) How do I find out which mobile devices has which JSRs in them.

Thank you. If my questions are stupid, please forgive me!!!

Answer 1

The JSR specification is made by the JCP Executive Committee, whereas their hardware dependent implementations are coded by the handset manufacturers (Nokia, Motorola, Samsung etc.) usually in native C++.

User manuals on the internet often list the supported JSRs of the device, sometimes in form of a two-dimensional grid/table.
