installing lawson handheld software on Motorola Symbol 8880

Hi We have Motorola Symbol 8880 handheld devices and cradle that connects to our Lawson server. The Symbol Handhelds run Microsoft Pocket PC. I also have files for ecoonect and MPC.jar. 

eConnect.cpl
ecoonect.lnk
eConnect.exe
eConnect.reg
eConnect.cpy

and MPC.jar.


I need to know how do I install the MPC.jar file.
Where do I copy the Jar file.

The eConnect files are located in these directories.

\Application
\Windows\Startup
\WIndows

Does anyone have instruction about installing and configuring the Motorola Symbol Handhelds to work with Lawson software.

thanks,
Baziz
