HOWTO Windows 10

[bertalanimre]

I'm having a hard time compile it on Windows10. I've installed both JDK and JRE with the same version, however, I'm unable to compile.
At first, the error message was:

[ERROR] error: Source option 5 is no longer supported. Use 7 or later.
After writing 7 into pom.xml (source7 and target7)

[ERROR] C:\Java-Websockify-master\src\main\java\com\netiq\websockify\WebsockifyProxyHandler.java:[33,23] error: package javax.activation does not exist
[ERROR] C:\Java-Websockify-master\src\main\java\com\netiq\websockify\WebsockifyProxyHandler.java:[468,8] error: cannot find symbol
[ERROR]   symbol:   class MimetypesFileTypeMap
  location: class WebsockifyProxyHandler
C:\Java-Websockify-master\src\main\java\com\netiq\websockify\WebsockifyProxyHandler.java:[468,48] error: cannot find symbol

Any ideas?
