The main purpose of JSP is to separate the business logic & presentation logic. DB connections deal with pure java code. If write this kind of code in JSP, servlet container converts the JSP to servlet using JSP compiler which is the time consuming process so this is better to write code which deals with DB connections, Authentication and Authorization etc. in the java bean and use the <jsp:bean> tag to perform the action
Why DB connections are not written directly in JSP’s?
