Re: OpenJMS on Android

Hi,

As an alternative solution I can recommend you to try Softwired's
iBus//Mobile which has JMS based library client libraries specifically
designed for Android as well jme and .net cf. An evaluation copy of
Softwired's iBus Mobile is available for download from our DEV ZONE [See the
product .html  for product features and technical specifications] 
http://www.softwired.ch/insidesoftwired/.

Even if you get the OpenJMS or another JMS implementation running on
Android, the results will not be satisfactory since most of them are
designed for the wired networks and can not handle the disconnected
operation & other problems of the wireless networks  gracefully.

Cheers
