Hi Guys,

Can someone please tell me why m-business client doesn't support a j2me
version? There are J2ME web browsers in the market that support Java
Script, but don't support CSS and DOM.

This might be a stupid question, but why does m-business client 5.7 need
DOM and CSS. Does it have anything to do with connecting to the
on-device xml database? I thought it used a java script pod to connect
to this database?

Any information on this would be highly appreciated as we are exploring
the option of using a 3rd party J2ME browser to support our customer's
Java based devices. I would like to know what problems I should expect
to run into during this process.

Thanks,
Abbey

Probably for the same reason you don't use a java based browser on the
desktop, only more so since handhelds and smartphones have much less memory
and processing power than the desktop. J2ME browsers don't support CSS and
DOM because to write a browser that complex in Java would be too big and
slow for a constrained device.

You connect to the database for data, but without the ability to manipulate
the DOM you would have a hard time displaying it. If you want to dynamically
create pages from on device data offline without DOM access you would
basically have to write a web server that lives on the device that vends
dynamically created pages to the J2ME browser.

They will be slow and have no offline support.
