Hi,

Yes I had this problem some time ago and found the following solution,
but there may be a better one.  If you look in ParameterDatabase there
is a constructor taking and inputStream as an argument which is what is
required when reading from jar.

You can then use something like: 

        java.io.InputStream stream = getClass().getResourceAsStream(
"/ec/display/myApp.params");

        parameters = new ParameterDatabase(stream)

I think within the ParameterDatabase constructor you need to add
something like: 

         parents.addElement(new ParameterDatabase(
                    this.getClass().getResourceAsStream(s)));

to allow for loading parents from the jar.

And in each parameter file you need something like

parent.0 = /ec/gp/koza/koza.params

rather than

parent.0 = ../../gp/koza/koza.params


Hope that helps,

Laurie

Subject: ECJ as executable jar and param files

I want to put ECJ with my extensions in a .jar, so that others can
easily
run it and test my evolutionary experiments. But I have problems
managing
the parameter-files which include each other.
When I define a parameter file for my problem, is there a way to include
other within the jar (e.g. simple.params) or do I have to copy&paste it
into
the problem file?
