问题 I created an executable jar file with eclipse indigo, but when i double click on it nothing happens. But when i write java -jar c:/dir/filename.jar to cmd, it works. Other jars runs well. I'm using jdk 1.7.0_02 and eclipse indigo. How could i start it normally? 回答1: You can run a jar by double clicking it, you just have to make sure that Java is associated with .jar files.

问题 Is there some way to call a script within a jar without extracting it? 回答1: Python will interpret a file named "__main__.py" stored inside a zip file, if called with one as a parameter.

(Importing other Python modules from

问题 I want to add some class files to rt.jar . How am I able to do that? 回答1: Your question indicates you have some misunderstanding of the java platform. First of all you need to know what the rt.jar is and what it does: rt.jar is the jar that contains all the classes necessary for the java runtime. Hence it's name rt .jar Now that you know that, you need to know how your java program runs: Your java program, all your jars and classes are executed by the java virtual machine. So as you can see

问题 When I export the default libgdx project as a runnable JAR file from eclipse and then run the .jar file, it simply pops up a black screen and then closes. When I run the project code from inside Eclispe, it works fine. The correct red screen with the "bad logic" logo is displayed by the program (this is what is supposed to happen). If I build the project from the command line using gradle with the command gradlew desktop:dist as instructed here and then run the jar that is created, it will
