I'm using JarFile and JarURLConnection to load files out of a jar file. I'm then taking the classes, and loading them via BCEL (ByteCode Engineering Library, apache library). I cant just directly use a class loader because im modifying some classes slightly with the BCEL. I need to load the classes by their bytes into my bcel loader. However, one of the classes I'm loading references a resource. This resource is inside of the jar, so I can get the file (When iterating over the entries in the JarFile, I ignore the regular files, and take the class files for loading later). But just having the file won't do me any good, as the class loads it as a resource. Is there any way I can take that resource from the jar (well I can take it and load it into a byte[], the next part is the issue) and dynamically add it as a resource for my program, so that the classes that I load wont be missing their resources?
Got a lot of stuff here, if anythings confusing, ask in comments, I might've said something wrong, or missed something altogether :) Thanks
I'll show a little of my class loader here (extends ClassLoader):
@Override
public URL getResource(String name) {
System.out.println("LOADING RESOURCE: " + name);
try {
return new URL(null, name, new Handler(files));
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
Now, it is printing out "LOADING RESOURCE: filename", but its then giving me a MalformedURLException (I have no protocol atm, just a file path, that's not a true valid path, but it's just an attempt to give it to my Handler class below).
class Handler extends URLStreamHandler {
@Override
protected URLConnection openConnection(URL u) throws IOException {
return new URLConnection(u) {
@Override
public void connect() throws IOException {
}
@Override
public InputStream getInputStream() throws IOException {
System.out.println("IS: " + url);
return /*method to get input steam*/;
}
};
}
}
The /*method to get input steam*/ is set in my real code, but that's not relevant here. So any further ideas with this?
