Install, configure JAVA8 under Windows

After installing and downloading JAVA8, configure the Java environment, I configure the environment variable to add or modify path according to the personal production environment; Java_home,classpath path is to facilitate the system to find Java.exe, Javac.exe and other programs, Java_home is a variable, convenient path and classpath configuration, Classpath convenient system Find JAVA supplied jar file Java_home = "C:\Program files\java\jdk1.8.0_11 path=path +";%java_home%\bin;%java_ Home%\jre\bin; "Classpath =".; %java_home%\lib\dt.jar;%java_home%\lib\tool.jar; "

So try to remove C:\Program files\java\jre8\lib\amd64\jvm.cfg to see if Java will repair itself. Unfortunately, there is no usual wish. But what makes me wonder is that the directory set in the environment variable is C:\Program files\java\jdk1.8.0_11, and the error prompts the jvm.cfg in Jre8. Regardless of these, the C:\Program files\java\jdk1.8.0_11\jre\lib\amd64\jvm.cfg copied to the C:\Program files\java\jre8\lib\amd64\ under the error, This is java/lang/classnotfoundexception:error in opening JAR file C:\Program Files\java\jre8\lib\rt.jar Well, and will Java_ The rt.jar underneath the home has replicated the past
