How to use/call .class file in jdeveloper

Question

I have a .class file that is run as part of cron job on the UNIX server. It has three parameters - so the call goes something like this java exampleClass1 param1 param2 param3.
I need to import it into my Jdeveloper project so it can be called from a web application. Please help.
I tried importing the directory as a library(was I supposed to jar it first?) and updated classpath to use the directory with this class file too. But in my code...how do I call exampleClass1?

Answer 1

If the exampleClass1 does have a public method which is called from the main method, when you run it from the command line
should work like this
// sample class
public class ExampleClass1
    // C'tor
    public ExampleClass1 ()
    public void testmethodWith3Params(String aS1, String aS2, String aS3)
        // do the work here
    public static void main(String[] args)
        String p1;
        String p3;
        String p3;
        ExampleClass1 xyz = new ExampleClass1();
        // read the params into p1,p2 and p3
        // omited the code
       // call the worker method
       xyz.testmethodWith3Params(p1,p2,p3);
// now instead to call the main method you call the workter methos from your web app like
ExampleClass1 aaa = new ExampleClass1 ();
aaa.testmethodWith3Params(param1, param2,param3);
...If you don't have a method (or don't know it) you can call it via the main method like
String [] param= {p1,p2,p3};
ExampleClass1.main(param);Timo
