JDBC stands for Java Database Connectivity which is a set of interfaces and classes provided by Sun to access relational database in a vendor independent manner from Java platform. Database vendors who would like to support JDBC API implement these interfaces and classes and package them which is called JDBC driver.

JSP is a server side component for building dynamic web applications based on Java platform. It provides dynamic scripting capabilities within static HTML or XML content. It is extended from Servlet, another server side component to build dynamic web applications. A typical JSP file consists of static content like HTML tags along with Java code snippets which are embedded using special tags. JSP compiler compiles the JSP file into servlet during run time which is executed in Java application server like Tomcat.

XML is the de facto standard for exchanging information between disparate systems. Suppose you are a furniture manufacturing company and your dealer/distributor wants to place order requests to you. You create a mail-in database and ask your client to email order requests in XML format. In mail-in database you parse the XML and create Notes order request documents. Once order request went through approval cycle in Lotus Notes, sales order is generated in your backend legacy or ERP system. Sounds cool?
