I have two main classes in the app. When I package it to a runnable jar (using Eclipse export function) I have to select a default main class.
Is there a way to access the non-default main class from the jar at runtime?

You can access both via
java -cp myapp.jar com.example.Main1andjava -cp myapp.jar com.example.Main2. The default main class in the jar is for when you invoke your app viajava -jar myapp.jar.See JAR_(file_format) for more details. When you select the main class in Eclipse this is what gets set in:
Main-Class: myPrograms.MyClassinside of the jar manifestMETA-INF/MANIFEST.MFin side of the jar file.
