Hi,
I would like to know how PDA can be used along with Java,ASP.NET etc.,
I have designed(1.5 year back) some J2ME (mobile phone)applications - "Mobile based shopping" and i have some idea on using mobile along with Servlets.
Simillarly, Where I can find more info on using PDA along with Servlets or ASP.NET.
Some questions:
To run Java in a mobile, it needs j2me installed, do we have similar constraints with PDA's.
I found many PDA's comes with Microsoft Pocket PC OS, what is use of that OS, can it interact with ASP.NET programs?
Your help could be much appreciated.
Regards
Balaji

Yes, you do need to install a j2me runtime on top of PalmOS, PocketPC, Linux or whatever other OS you have on the PDA. Just like that you need to install J2SE on your win2000 to use desktop Java.
However, one PDA -- Sharp Zarus, does come with Java pre-installed over Linux.

I found many PDA's comes with Microsoft Pocket PC OS, what is use of that OS, can it interact with ASP.NET programs?

PocketPC is just an OS. To interact with ASP.NET apps, you can use win32 APIs that is built into the OS or you can install a .NET Compact Framework runtime for .NET APIs.

Hi Michael,
Thats really interesting reply for me.
Man! You had wrote lot of articles!. :roll:
I have two questions:
1.If a PDA comes with Pocket PC, then it will have Internet Explorer, now i can directly access web sites ending with .jsp /servlet or .aspx, then why i need j2me runtime on it ? Am i missing something. ?
2.In mobile we ourself cannot install j2me runtime unless its been done by product manufacturer. Example siemens sl45i, nokia 7650. Is that same case in PDA ??
Thanks for replying.
Regards
Balaji

IE provides a "thin client". To process data on device, you need a thick client solution. Both J2ME and .NET CF are thick client platforms.
All Internet cell phones come with WAP browsers that can access web contents, who do you need J2ME there? It is the same reason.

2.In mobile we ourself cannot install j2me runtime unless its been done by product manufacturer. Example siemens sl45i, nokia 7650. Is that same case in PDA ??

You can install Java runtime on pocketPC yourself. It is just another pcoektpc application packed in a CAB or exe file. You can download it using your pocket IE or sync it from a desktop.
