try running the server with --verbose to see if any messages are logged. If not, try with --debug.
Also try running the sample shipped with weinre. The main weinre page, at the URL displayed in the console when weinre is started, has the URLs to the demo page, listed under the section "Target Demos". You should see links to the demo displayed as:
* the non-minified demo
* the minified demo
* the non-minified strict demo
Try running one or more of these to see if they work.
