Is it possible to sign a jar file as you export it from Eclipse 3.5? Or a plugin to allow this to happen?
I can easily export a runnable jar, and sign it myself using jarsigner, but manually doing this every change is not efficient.
If there is no plugin, a possible alternative is to setup an ant script to do the operation for you on demand.
The JAR Signing mentions the Platform-releng-signedbuild script as an example, completed with a few tips.
