Jsp expression language not evaluated in .js files

Question

I am making a Java EE 6 application and using Glassfish 3.1.2.2.

I wan't to use EL inside a jquery script, stored in a sepparate .js file but I can't get it to work. This is the script:

$(document).ready(function(){
    $("select#classLabel").change(function(){
        var unsetList = ${classyJson};
        var chosen = $("select#classLabel").val();
      $("select#classSubLabel").val(chosen);
    });    
});

And I get the following error message from netbeans:

"subLabelSet.js: Expected ; but found { Expected semicolon ; after 'classy'. The global variable 'classy' is not declared."

The same script works fine if I put it directly in the .jsp file like this:

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Titly</title>
        <script type="text/javascript" src="js/jquery-1.10.2.js" ></script>
        <script type="text/javascript" src="js/generateSavedSearchTable.js" ></script>
        <script type="text/javascript" src="js/subLabelSet.js" ></script>
        <script>
            $(document).ready(function(){
                $("select#classLabel").change(function(){
                    var unsetList = ${classyJson};
                    var chosen = $("select#classLabel").val();
                  $("select#classSubLabel").val(chosen);
                });    
            });
        </script>
    </head>

This reminded me of a problem I had before where I couldn't get the EL to evaluate inside files ending in '.jspf'. This I fixed by adding:

    <jsp-property-group>
        <description>Used to enable interpretation of EL in jspf files</description>
        <display-name>jspf</display-name>
        <url-pattern>/WEB-INF/jspf/*</url-pattern>
    </jsp-property-group>

in the web.xml file. But when I try to do the same for .js files:

    <jsp-property-group>
        <description>Used to enable interpretation of EL in javascript files</description>
        <display-name>javascript</display-name>
        <url-pattern>/js/*</url-pattern>
    </jsp-property-group>

I does not work and I get the following error:

Any ideas on what is going wrong and if/how I can fix it?
