When you do a POST on your HTML form, the browser sends the form fields to the server. If you have a servlet there, you can take the values and make XML by building strings or building a DOM and exporting it to string or whatever makes your day.
I briefly worked on one system where the buttons on forms did not do POST, but ran JavaScript in the browser that generated XML, put the XML into a hidden field on another form, and finally posted that form. Whew. That way their server saw only XML, never the form fields.
Did that make sense?

Here's an idea off the top of my head:
Create your javabean, but along with the usual getter & setter methods, have a setter method for each property that accepts a string, and knows how to convert the string to whatever type it is.
in your HTML form, name each field exactly as the javabean property is named, also put a hidden field in the form with the classname of the javabean.
Make a filter (which runs before servlets) that goes through all the request data, and
1) gets an new instance of the javabean based on the classname field.
2) for each parameter,
2a) looks for a method named set[ParameterName] that accepts a String
2b) invokes that method on the bean, passing it the ParameterValue
3) puts the object in the request attributes/context
and then when it gets to the servlet, have the servlet extract the bean.
