Hello,
I am trying to launch a JWS app on a computer that has JRE 1.4.1 and Web Start 1.2 on it. The problem is that the application is compiled with version 1.4.2 and won't launch when I simply specify J2SE version 1.4 because of a "wrong minor version number" error. So I am attempting to specify J2SE 1.4.2+ in the JNLP file and it works just fine on my computer with JRE 1.4.2_05 on it. However when I attempt to launch it on the computer with 1.4.1 on it I get the error "No JRE version found in launch file for this system". Below is all the information I could get out of the JWS console. It was my understanding that JWS was supposed to be able to download a new version of the JRE when needed. Am I specifying something wrong in the JNLP file? Any input is appreciated.
Thanks,
Dave
