notepad 里面如何配java插件

我用notepad++配置java环境时为什么会出现这样？？环境变量也配了，命令端可以运行到Notepad就不行了
CD: F:\
Current directory: F:\
java Hello
Process started >>>
Error: opening registry key 'Software\JavaSoft\Java Runtime Environment'
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.
<<< Process finished. (Exit code 2)
