I don't understand what you mean by the "same dynamisum", but if you mean
the same GUI based interface as your Swing application you'll need to use an
applet.  You will have browser compatibility issues, IE users will need to
download and install Sun's JRE in order to view it.

Your question regarding how to present your information in JSP is very
broad.  It depends on various factors.  Is your current business logic in
Beans?  If so they would be the obvious choice.  Very basically, Beans use
Setter and Getter methods to calculate and return objects.  For example you
could have a bean class called TableBean with a setTable method that queries
a database and generates an HTML table and stores it as a String, and a
getTable object that simply returns that String.  You put a tag in your JSP
which tells it where the bean is:

<jsp:useBean id="TableBean" scope="page" class="beans.TableBean" />

Scope determines how long the bean persists, you can have page, response,
session or application scope.

The setProperty tag will pass parameters to the method in the bean, for
example to add to your SQL query of the database.  You can use information
entered in forms here:

<jsp:setProperty name="TableBean" property="variable1" value="foo" />

Then you put a getProperty tag in your JSP where you want the table HTML
displayed:

<jsp:getProperty name="TableBean" property="table" />

Tag libraries or basic servlets are other possibilities, and you might want
to look into Struts as well.  This is just the very basics, you can do a lot
more than this.  You should get your hands on a good JSP book or tutorial on
the web.
