I have developed and signed (thawte certificate) a java programm with the wtk V2.3 from sun.
By installing it on a "nokia 6110" with "nokia application installer" there is a installation process with several messages on the phone.
It works fine.
The same thing on "nokia 2710 navigation edition" brings no messages on the phone. The files are only copied to the chosen destination.
When I try to start the programm there is a message "invalid programm, delete?".
When I look at the details of the file on the phone there is a information "certificate: no".
Can anybody help me?
