I had the same issue on Windows 7 and I had to install both JDK and JRE and it's a success.

Answer 2

I just spent about 1 hour to figure out possible solution for the same error.

So what I did under MS WIndows 7 is following

1. Uninstall all Java packages of all versions.

2. Download last packages Java SE or JRE for your 32 or 64 Windows and install it.

3. First install JRE and second is Java SE.

4. Open text editor and paste this code.

   public class Hello {

     public static void main(String[] args) {
   
        System.out.println("test");
   
     }
   
   } 
   

5. Save it like Hello.java

6. Go to Console and compile it like

javac Hello.java

7. Execute the code like

java Hello

Should be no error.

Answer 4

Try placing the desired java directory in PATH before not needed java directories in your PATH.

Answer 5

please try to execute java from

C:\Program Files\Java\jdk1.7.0_10\bin

i.e from the location where java is installed.

If it is successful, it means that the error lies somewhere in the classpath.
