Nathan Maves commented on IBATIS-299:
-------------------------------------

Ken,

This is a perfect example of how to extend the framework for your specific requirements.  I am not saying that this is a no go but do you believe that this is a common data type that people would be writing this type of CTH for?  We can not include a type handler for every different type of java object.  Just my 2 cents.

> It would be nice if iBATIS came with a TypeHandlerCallback implementation for mapping URL object properties to their String representation stored in a database field.  Here is some code that could be used to implement this:
> package com.ibatis.sqlmap.client.extensions;
> import java.net.MalformedURLException;
> import java.net.URL;
> import java.sql.SQLException;
> import java.sql.Types;
> /**
>  * An iBATIS type handler callback for java.net.URLs that are mapped to
>  * Strings in the database.  If a URL cannot be constructed based on the
>  * String, then the URL will be set to <code>null</code>.
>  * <p>

> public class UrlTypeHandlerCallback implements TypeHandlerCallback {
>     public Object getResult(ResultGetter getter) throws SQLException {
>         String value = getter.getString();
>         if (getter.wasNull()) {
>             return null;
>         }
>         return this.valueOf(value);
>     }
>     public void setParameter(ParameterSetter setter, Object parameter) throws SQLException {
>         if (parameter == null) {
>             setter.setNull(Types.VARCHAR);

>             setter.setString(url.toExternalForm());
>         }
