Ok.. if finished that workaround. I don't know if it will break anything
else, but at least it fixes our test case. To use it, add the following
line to the top of the tstMO main() method.
FileURLSpaceFixer.install();
below is the FileURLSpaceFixer.java file.
-------------------------
import java.net.URL;
import java.net.URLStreamHandlerFactory;
import java.net.URLStreamHandler;
import java.net.URLConnection;
/**
* Used to fix the problem with the RMI classloader for
* when a space appears in the path to where a class
* should be loaded from.
*
* @author: Hiram Chirino
*/
class FileURLSpaceFixer {
private static FileHandler fileHander= new FileHandler();
private static CustomURLStreamHandlerFactory
customURLStreamHandlerFactory= new CustomURLStreamHandlerFactory();
//
// This class is used to hook into the URL protocol parsing sysytem
//
private static class CustomURLStreamHandlerFactory implements
URLStreamHandlerFactory {
public URLStreamHandler createURLStreamHandler(String protocol) {
if (protocol.equals("file"))
return fileHander;
return null;
}
}
//
// This class will override how the file handler is implemented.
//
private static class FileHandler extends
sun.net.www.protocol.file.Handler {
// When we externalize the URL we want to make all the spaces in the
file name
// a '+' character
protected String toExternalForm(URL u) {
String s= super.toExternalForm(u);
return s.replace(' ', '+');
}
// When we load a URL in we want to convert all the '+' characters in
the file name
// into spaces.
protected void parseURL(URL u, String spec, int start, int limit) {
super.parseURL(u, spec, start, limit);
setURL(u, u.getProtocol(), u.getHost(), u.getPort(),
u.getFile().replace('+', ' '), u.getRef());
}
}
// use this method to install this fix.
public static void install() {
URL.setURLStreamHandlerFactory(customURLStreamHandlerFactory);
}
}
