Prequsite for launching an applet

What is the Prerequsite for Launching a swing applet from Windows PDA mobile.???

Thanks in advance.

You'll need to install a JVM of some kind; some options are mentioned here.

So , for launching applet in MS enables PDA installing CrEme™ - The Java™ Enabler for Windows® CE
is a must?

As that article explains, there are several options; CrE-ME is just one of them.

I have some doubt, pleas clear me...

1. Why we cannot launch Applet in PDAs like we do in our windows desktop, why it requires some thrid party tools??
2. Do we need to signed the Jar files for accessing the system reource like we do for the desktops???

I'd guess that Microsoft has more control over the distribution of Windows Mobile than it does over the distribution of desktop Windows. But it's not clear that there is much demand for a JVM on Windows Mobile, so the handset manufacturers or mobile network operators probably don't have much to gain by adding a JVM even if they were allowed to do so.

2. Do we need to signed the Jar files for accessing the system reource like we do for the desktops???
