What steps will reproduce the problem? 1. Click File->Open MIDlet URL 2. Enter http://mini.opera.com/download-5/opera-mini-latest-advanced-en-us.jad?no_redir&i smobile=false What is the expected output? What do you see instead? Expected the jad to be opened. Get "Empty jar http://mini.opera.com/download-5/opera-mini-latest-advanced-en-us.jad?no_redir&i smobile=false" error dialog box with an OK button. What version of the product are you using? On what operating system? Any. Win7.

Here is some more information:

The reason is because in 
/trunk/microemulator/microemu-javase/src/main/java/org/microemu/app/Common.java

function: openMIDletUrl(String, MIDletClassLoader)
The following is tested:
 if (urlString.toLowerCase().endsWith(".jad")) {
                jad = loadJadProperties(urlString);
                loadJar(urlString, jad.getJarURL(), midletClassLoader);
            } else {
                jad.setCorrectedJarURL(urlString);
                loadJar(null, urlString, midletClassLoader);
            }

So we can see here that the jad is loaded as a jar.
But I think the Content-Type returned from the URL (perhaps with a http HEAD 
call if available) should be checked for the jad mimetype first 
("text/vnd.sun.j2me.app-descriptor"), and then fall back to the jar loading if 
that fails.

Lastly, when this error does occur the status bar at the bottom stays on 
"Loading...", and opening another jad or jar from filesystem does nothing.
