I can compile and run a java program. The debugger appears to work, though there are
two things missing.
1. There is no "=>" pointing into the source file window when I step through the
program.
2. The jdb menu does not appear, even after following the instructions to insert a
breakpoint and to return to the source file.
Here is the program I am experimenting with:
/**
* The HelloWorldApp class implements an application that
* simply displays "Hello World!" to the standard output.
*/
class HelloWorldApp {
public static void main(String[] args) {
System.out.println("Hello World!"); //Display the string.
}
}
Listed below is the JDE/Emacs environment. Thanks for your help.
