如何使用批处理文件运行两个Java应用程序？

Question

I want to run two java applications located in two different projects in eclipse at the same time automatically , I guess using a batch file is the best way to do this. Is that correct? or there are better ways?

If it's the best way, what would be the syntax for the batch file? Do I need to have jar files for the projects? Does batch files work only on windows?

Answer 1

start java path\of\first\class
start java path\of\second\class

This will launch both at the same time, assuming that's what you're looking for. The applications don't have to be packed in a jar, you can also pass the path of the class containing the Main you'd like to run. You might have to pass a few more arguments (such as classpath), depending on your setup.

And yes, this will only work on Windows (and possibly on Dos).
