Some good solutions there Denis. Although for modern web services EJBs
are a little bit bloated. It would be much better to have a lightweight
framework like Spring. It seems to me that the mainframe (z/OS) is
seriously lagging behind on that front. The whole SOA SOAP/WSDL approach
is considered obsolete by the majority these days.

Hi,
Another idea is to implement a VPN Gateway.
So the mobile device connect to the VPN Gateway via certificates. The VPN
connection would be encrypted. There are solutions by companies which could be
a manditory app install on the mobile devices for monitoring what is installed
there and only allowed apps on the device are allowed to use the VPN
connection. It would also allow to remotely wipe out the mobile device, e.g. if
a malware tries to do a Denial of Service attack. The mobile device is simply
reset to factory settings as an example.
Then create a mobile website which is designed for mobile devices and runs on J2EE app server which uses IMS TM Resource Adapter to access IMS Transactions. So one could have EJBs, servlets, etc. that access IMS Transactions. Even service flows could be accessed. Or IMS SOAP Gateway for using SOAP Requests from the mobile device.
Since with the VPN Connection and a dedicated port on IMS Connect it would
also be possible to write an IPhone or Android app which uses the Java
components of IMS TM Resource Adapter or IMS Connect API to connect to IMS
Connect using a direct connection.
However that is a more difficult design and architecture discussion, but I like
to make clear that this is not limited to 3270 emulators running on mobile
devices.
Hope that helps,
Denis.

Can you do SSL connection on those toys? [1]
[1] - I have a free TN3270 client [2] on my iPhone 5 and connected it via a SSL
port using RACF certificate. At least my POC was successfull, so in case we need
to move on, the technology is already established.
[2] - with limited PF key functionality. You need to buy [ I'm too cheap to do
it ;-D ] the whole thing to make that 3270 client 100% useful. ;-)
