I understand more now. My thinking is your "Java" code is your secret sauce which is being refined, and you need to reduce the manual effort (and possible introduction of errors) in relating that back to the "connection" to the Alert/Real-time data (this update needs to be as "no-touch" as possible to make the mechanism as seamless as possible). I am unaware of an off-the shelf solution. However, if you had a PC allowed to be running with Excel (for RTD connection to TOS), and use a mechanism suggested earlier by another poster, to have the SMS, email, or whatever Alert you desired be generated from Excel (or other app), it seems you can control all your variables. Note: You can use Excel as a conduit to the RTD if you like if you prefer to code only in Java. -- use a Win32 API to dynamically create the Excel sheets & RTD references desired and control externally from your preferred code. -- That is what I do (from Perl). -- But you would need a PC running, which you indicated is not what you desire.
If you do discover an acceptable solution, I hope you post your findings. Good luck.
