Hi,
public class SimpleJava {
public void main(String[] args) {
System.out.println("Here we are");
then, i created .class file and ready to be loaded into oracle database using loadjava utility. i already loaded it successfully into a database. but, when i use pl/sql to call it in SQl*Plus, i got this error.... can anyone help me to solve this problem?Did you run the SimpleJava in your ED or on command prompt??
I created the same class file but when I said
java SimpleJava
It threw the following error
java.lang.NoSuchMethodException: No applicable method found
So modify your code
as
public class SimpleJava {
   public static void main(String[] args) {
        System.out.println("Here we are");
