How to use Electroserver's built in Derby Database?

Question

hello. I am trying to create an online multiplayer game with electroserver like here:
http://gamesfromjames.weebly.com/pickit.html
I was looking at the source code from electrotank. Unfortunately, I cannot compile it in flash CS6 because the document class is in mxml.(if someone can help me figure out how to test these examples  in pure as3 that would be great)  I did find these two functions in hte mxml class:
             * Increases your rank by the amount specified by sending a properly formatted message to the plugin.
            private function addToRankClicked():void {
                var ipr:PluginRequest = new PluginRequest();
                ipr.pluginName = "DatabasePlugin";
                var esob:EsObject = new EsObject();
                esob.setString(PluginConstants.ACTION, PluginConstants.TAG_ADD_TO_RANK);
                esob.setInteger(PluginConstants.TAG_ADD_TO_RANK, rankDeltaStepper.value);
                ipr.parameters = esob;
                _es.engine.send(ipr)
             * Loads your rank from the database by asking the plugin for it.
            private function getRank():void {
                var ipr:PluginRequest = new PluginRequest();
                ipr.pluginName = "DatabasePlugin";
                ipr.zoneId = -1;
                ipr.roomId = -1;
                var esob:EsObject = new EsObject();
                esob.setString(PluginConstants.ACTION, PluginConstants.TAG_GET_RANK);
                ipr.parameters = esob;
                _es.engine.send(ipr)
Is this all that is needed to put things into the database and take things out or am I missing something?
If I was going to try to save the chat history and show it every time a user enters the chat room, how would I go about doing it with electroserver's derby database?
Thanks!

Use Flex/Flashbuilder to compile mxml source code.
There are many Flash Games on their Example site: http://www.electrotank.com/docs/es5/manual/
