Hello Support,
I'm trying to read an external config file for my strategy.
This config file must not be included in the external jar, since I do not want to recompile on every property change in this file.
In the attachment I have created a simple strategy which uses an external jar(you need to adapt the path to the jar of course).
In the jar example you can see that the xml file is correct loaded when it is in the jar file.
But I cannot get it loaded if the xml file is external to the jar(I tried the simplest case and putted the xml file into the same folder as the jar file).
You can also see that the MANIFEST.MF has one entry for the Class-Path: .
This means the current directory and I don't know why the Dukascopy classloader(com.dukascopy.dds2.greed.agent.a.c) does not look up this folder.
Please help, since I think that config files are very useful.
Thanks,
Juergen

Why are you trying to load a resource by classloader which is not within its classpath? Why not simply use the FileInputStream?

For FileInputStream you need the absoulte path to work.
I want to be able to put the xml file relative to the jar.
And since this may differ on any machine I want to be independent of absolute paths.
I have no problems with normal applications to put config files relative to jars, but only when using JForex.
This is because the path starting with "jfx://..." does not give me a local file path which may be because it is a JavaFX application?!
Can you provide a solution with a relative path working?
