I've downloaded lots of JAVA (.jar) games for my phone (Sony Ericsson K750i).

I want to play them on my PC before I upload them to my phone.

What do I use to play them? It's default is 'Java(TM) 2 Platform Standard Edition binary', but I get 'Failed to load...'

Any help on playing them? I had a search around but it kinda confuses me :-\

Thanks.
