How do you get the image file from the database with JSP?
You can retrieve an image file from a database in JSP by writing a servlet that fetches the image from the database and streams it to the JSP page. The servlet will set the content type to "image/jpeg" or the appropriate image format and write the image data to the response output stream. In the JSP page, you can then display the image by setting the source attribute of the img tag to the servlet URL.
What is the difference between table of context and index?
A table of contents provides a list of main headings and subheadings in a document or book in the order they appear, helping readers navigate the content.

What is a session What are the different ways of session tracking in servlet programming?
Why do we need a Session?When one page needs to share information with another, the scope of the data broadens beyond processing a single request. This is because, when a response gets committed, all the data that was held in the request that generated that response is destroyed. So, if you want that data in another page, you will be looking at a blank request object with no data in it. When such a need arises, you must send the data from one page to the server and from the server to the next requested page, whether it be the same page or another page altogether. There are several ways to share state information between requests. However, the primary or the easiest way is to use sessions.How Do Sessions Work?The container generates a session ID. When you create a session, the server saves the session ID on the client's machine as a cookie. If cookies are turned off then it appends the ID in the URL. On the server, whatever you add to the session object gets placed in server memory-very resource intensive. The server associates that object in memory with the session ID. When the user sends a new request, the session ID is sent too. The server can then match the objects in its memory with that session ID. This is how we maintain client state.
What information goes in the header along with the page number?
