Calling java.exe using Runtime.getRuntime().exec()

Posted: Mar 15, 2004 7:57 AM

I am using Runtime.getRuntime().exec(cmd).

if cmd = "javac File.java"
{
it works but after compiling the FIle.java
}

I also need to execute it. How could I execute it using Runtime.getRuntime().exec()?

i TRIED Runtime.getRUntime().exec("java.exe File.class") but it doesnt work at all. And another problem I also need to execute the class file and get the output at the same time... how could I do that... ? Please help me O_o

Thanks

Remove the ".class" part of it and I think it should work.. Also, if you are giong to execute the program consider using sun.tools.java.Main method from the tools.jar of JDK.
