That is what J2EE (Enterprise Edition) is for. It provides for
servlets, JSP, Sessions, SOAP, Messaging, and a host of other bits.

JSP is in Sun's J2EE (and in Tomcat separately). It caters for 'code in
page' where an HTML page contains tags that have server side Java code
in them (as distinct from client side JavaScript or Java applets).
Nominally this is processed by the server as the page is sent to the
client, but in fact the page is processed into being a servlet (once)
and this is exectuted to send the page.
Servlets are small modules that run on the server, they need an
application server such as Apache's Tomcat or JBoss or WebSphere, but
basically this does most of the grunt work of web server applications.
