Answer 1

The value of the postURL parameter is a URL that can be parsed without exceptions, therefore the problem is somewhere else. What you can do:

• Experiment with various applet parameters
• Ask for support from the developers of the applet
• If you don't have the source code of the applet, you can probably still decompile it, and find out how it works: Where can I find a Java decompiler?

The following program shows only that the postURL value is OK for Java:

public class A {
    public static void main(String[] args) throws MalformedURLException {
        String s = "http://xxx.ccc.local/upload/up.php?aa=0&bb=Alvar%E1%2Ffg&cc=1028&from=documentos";

        URL url = new URL(s);
        String protocol = url.getProtocol();
        System.out.println(String.format("A::main: protocol = '%s'", protocol));
    }
}
