How do I submit code?

[Michael McGrady]

I got tired of trying to get some answers and listened to a couple of 
things Martin Fowler said on the users list and decided to just write my 
own tags.  I find I can write my own tags as easy as finding out how some 
of the existing ones work.  Some of that code is a little "dark"!  LOL

I have some code that I think improves PropertyUtils in commons and its 
ability to handle nested maps and other nested situations.  This also has a 
new class to go in with the bean options, which is really an improvement on 
the WriteTag in conjunction with changes to PropertyUtils in commons and 
RequestUtils in org.apache.struts.util.  I call the tag WriteMapTag and use 
it myself, as follows:

<map:write name="host" property="page(logon).key(bannerLeftColor)" 
scope="request" />

The central code for this is like the following:

public static Object getNestedProperty(Object bean,
                                         String property)
        throws IllegalAccessException,
               InvocationTargetException,
               NoSuchMethodException,
               ChainedException {
    Map map = null;
    if (bean == null) {
      throw new IllegalArgumentException("No bean specified");
    }
    if (property == null) {
      throw new IllegalArgumentException("No property specified");
    }
    int indexOfNESTED_DELIM = -1;
    int indexOfMAPPED_DELIM_L = -1;
    int indexOfMAPPED_DELIM_R = -1;
    String next = null;
    int loop = -1;
    if(!(bean instanceof Map)) {
      ChainedException ce = new ChainedException(new 
IllegalArgumentException("This is not a BeanMap object"), "This is not a 
BeanMap object.  The object is a " + bean);
      throw ce;
    }
    map = (Map)bean;
    String payload = null;
    while(true) {
      payload = property.substring(property.indexOf(MAPPED_DELIM_L) + 
1,property.indexOf(MAPPED_DELIM_R));
      loop = property.indexOf(NESTED_DELIM);
      if(loop > 0) {
        try {
          map = (Map)(map.get(payload));
        } catch (ClassCastException cce) {
          property = "Either you are using a class other than a map or you 
are burrowing too deep into the map.  The class cast exception trace is: " 
+ StackTrace.trace(cce);
          break;
        }
        property = property.substring(loop + 1);
      } else {
        break;
      }
    }
    // This need not return a string but it has to
    // return something whose payload is a string.
    return map.get(payload);
  } ///;-) Michael McGrady

With maps, the "page" and "key" are just toss ins.  If you specify a type 
atttribute, then these become method names with the parameters becoming 
arguments.  You get the idea.  How do I go about showing these to someone 
and seeing if they might be of some assistance?
