Thread: why mobile hardwares (except nokia) do not rely on non-java tech knowhow?

I'm not clear why do all mobile manufacturers make use of one single indispensable tool in java, when the web2 can be also be implemented by python (django, turbogears2, webkit (webwareforpython), spyce, zope, etc), ruby (rails, ramaze), perl (catalyst, mason/maypole), others, etc like how Nokia had done for its Symbian OS (using pylons -- a web2 framework of python, via mod_wsgi adapter of apache2).
Can one use a combination of lazarus-freepascal's fpc, codeblocks-mingw's gdc and django+rails to fulfil tasks which are currently accomplished with the frameworks of java (ejb) or dotnet (silverlight)?

Hi,

This is purely my view of why the mobile hardware(software stack to be precise ) rely on java tech.
It's pretty evident that the tech that you mentioned like python, ruby, perl ... are released under a license(GPL,PSF.. ) which makes it almost mandatory for the commercial company to release src code which most don't like to do. About Nokia using the non-java tech because they opened up symbian(more or less)BBC News - Symbian phone operating system goes open source. Now since Sun is acquired by oracle greater restriction(s) are bound to come, even your thread (What will be the fate of MySQL and OpenOffice in future) mentions the same.
