• Nonblocking io webserver/framework for java

  - by SeekingNonblockingIo

  Does anyone know of any node.js style webserver framework for java?

• Easy command line Java compile

  - by Nash0

  So I have to send a java project to someone outside our company who has no experience with java and they need to compile it. Is there an easy way to do it on the windows command line that does not require writing out lists of the files?
