Show us the code and show us the exact value that you pass in to the URL constructor. — Joachim Sauer

@Esailija, this is an applet, i don't have access to the source code. — daniel__

@loops how are you giving this to the applet, show the html or javascript source code. The url passed to the URL constructor is an empty string. — Esailija

Are you getting this error..... java.net.MalformedURLException: no protocol: {$VARS['HOST']}/upload/up.php?aa=0&bb=$idConsulta&cc=$COMPANYID&from=$from ........... — Jayamohan

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));
    }
}
