No problem, you got me curious about scripting...
I Tested with this
    protected void processRequest(HttpServletRequest request, 
HttpServletResponse response)
            throws ServletException, IOException {
        PrintWriter out = response.getWriter();

        out.println("<title>Servlet NewServlet</title>");
        out.println("<p>Stand Back... Script running</p>");

      ScriptEngineManager scriptMgr = new ScriptEngineManager();
      ScriptEngine jsEngine = scriptMgr.getEngineByName("JavaScript");
      try {
        jsEngine.eval("var meJavaScript = 'Me-Java Script!';");
        out.println("<p>" + jsEngine.get("meJavaScript") + "</p>");
      catch (ScriptException ex) {
        out.println("<p>Oh Damn! Script Crashed " + ex.getMessage() + 



Hey it works....
But in the process I discovered a few things....

+ Even if TC is installed on 1.5..... if NB is using 1.6 and its run from 
the DEV enviroment... it will make TC use 1.6
So... thats probably whats happening to you.
Its easy to check because in NB system out it tells you which JRE is used.
And  when you start TC from the BAT it will tell you... as well... in your 
case probably 1.5

+ The Source level makes no difference in a servlet.... ie if the JRE is 
1.6, you cant bring it down, this is different to normal Java Programs that 
will do things like tell you it now doesnt understand a template... but in 
servlets it seems to ignore that.

Anyway it works....
Quite neat.... the scripting thing....
May even be the beginning of a new chapter in TC.... there are always guys 
saying... "can TC run PHP", I see one can even run stuff like JavaFX
Thank u
