Re: [OpenMap Users] global layer properties

Thanks Don,

In my application I have extended the map properties file to allow me to
control other aspects of my program. So, I'm loading the map properties
and then setting all the appropriate objects. Doing this allowed me to
add 'globals layer settings' for the layers. What I'm defining are
properties with a prefix of "global.layers" like this:

I then search the "openmap.layers" property and add the attribute to the
layer property if they don't exist.

        // Look for global layer settings and add them to the layer
specific settings
        String layers = props.getProperty("openmap.layers");
        ArrayList<String> globals = new ArrayList<String>();
        Enumeration e = props.keys();
        while (e.hasMoreElements()) {
            String key = (String)e.nextElement();
            if ( key.indexOf("global.layers")==0) {
        if (layers!=null && globals.size()>0) {
            StringTokenizer st = new StringTokenizer(layers," ");
            while (st.hasMoreTokens()) {
                String layerPrefix = st.nextToken();
                for (String key:globals) {
                    String attr = key.substring(14);
                    String layer = layerPrefix+"."+attr;
                    if ( props.getProperty(layer)==null) {
