环境变量问题

  I got the same error while starting Netbeans

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I try to restart Netbeans many times. Same error was repeating. Later I found it was happening as some other application is already using JVM. So I looked for such an application which was Tomcat Server. I terminated Tomcat and tried starting Netbeans again and it was fine. So try looking for any application that uses JVM.

stop   tomcat   java即可用
