Java

[David Webster]

All,

Is there a Java or ImageJ class/method that will return the current working
directory that a class file  resides? I have compiled a separate copy of
ImageJ.java, but can't seem to find out where the IDE I am using puts the
class file.

Ben,

I don't know if this would help as I don't recall seeing .config files in
the same dir as my class file (e.g. the plugins folder).

In any case, I was compiling imagej.java and didn't realize that when you
compile a package, a folder is created.

Thanx - David Webster

You can call getResource() with the .class file itself as parameter.

I know I'm being terribly clueless, but what class does getResources()
belong to?

Example: let's assume you have a class called MyClass and its .class file
is outside a .jar file. Then

        String path = MyClass.class.getResource("MyClass.class").getPath();
        File directory = new File(path).getParentFile();

will give you the directory in which MyClass resides, as a java.io.File
object. If the class resides inside a .jar file and you want the directory
in which the .jar file lives, it gets slightly more complicated:

        String path = MyClass.class.getResource("MyClass.class").getPath();
        if (path.startsWith("jar:")) path = path.subtring(4);
        if (path.startsWith("file:")) path = path.subtring(5);
        int bang = path.indexOf("!/");
        if (bang > 0) path = path.substring(0, bang);
        directory = new File(path).getParentFile();

Ciao,
Johannes
