Hi all,

I've been developing my strategy in netbeans up until now. I created some of my own classes which I'd like to use in the jForex applet for back testing. I've copied the jar file into the strategies/files folder as mentioned in: viewtopic.php?f=5&t=477&p=1427&hilit=Library#p1427

I've tried the following things:
1) copying jar file generated at build in the "dist" folder from my netbeans project folder
2) creating a separate project using the netbeans new project wizard and selecting "java class library"
3) following these instructions and building my jar manually: https://java.sun.com/docs/books/tutorial ... build.html

The error I get by 1) and 2) in jForex is "Package annotations must be in file package-info.java". I'm not sure if it's the javadoc options in netbeans which need to be tweaked where the problem lies....
For 3) I don't even get the jForex to recognize the jar file...which was very weird.

Thanks,
jForexUser

Hi,
please consider this sample https://www.dukascopy.com/swiss/english/forex/jforex/forum/viewtopic.php?f=7&t=225&p=3666&hilit=send+mail#p3666
This is sample with java-mail.jar file. Please, verify that this is working for you.
Here can you download javamail.jar file https://java.sun.com/products/javamail/downloads/index.html

I've tried out the example and have only changed @Library("C:\\temp\\mail-1.4.jar") to @Library("mail.jar"). I unpacked the javamail jar to my "files" folder.
This compiles fine for me and I'm still thinking it has to do something with a compiler option which jForex uses or some setting in netbeans.

Could you try compiling a custom class in netbeans and then including the jar file in an empty jForex strategy?

thanks again for the help!

Hi,
we prepared custom jar file. It consist only of one class TestingOutput, which simply prints on the java console: "Printed from jar". Here is source code for the TestingOutput class:

package com.dukascopy.test;

public class TestingOutput {
   public static void println(){
      System.out.println(" Printed from jar ");      
   }
}

And here is a source code for the strategy.

    .  .  .
import com.dukascopy.test.*;
    .  .  .
@Library("C://Temp//test.jar")
public class Strategy implements IStrategy {

   public void onStart(IContext context) throws JFException {
        TestingOutput.println();
   }
    .  .  .

ok thanks for this simple example! I have been able to get this compiling...mine is still coming up with the error...I have some new ideas, will try them out and will report back with some (hopefully good) results

thanks again!

ok, so I've solved the problem. I had apparently named the package and strategy the same name.
I had

package Strategy;

and then

....
public class Strategy implements IStrategy {
...

The compiler doesn't like this and that's why I was getting the error "Package annotations must be in file package-info.java".

Thanks for the help
