How to resolve a blank page when redirecting to a JSP page from a servlet?

If a servlet redirects to a JSP page and displays a blank page, there could be several reasons and solutions for this issue:

1. Review the JSP page code to ensure there are no syntax or other errors, such as missing closing tags. You can try accessing the JSP page directly in a browser to see if it displays correctly.
2. Check the servlet’s redirection code: confirm that the redirection code in the servlet is correct, for example, using the response.sendRedirect() method for redirection and ensure that the redirection path is set correctly. You can try printing some debugging information in the servlet to confirm if the redirection code is executed successfully.
3. Check the web.xml configuration: if mapping servlets and JSP pages using web.xml, make sure the configuration is correct. Verify that the URL mapping paths for the servlets and JSP pages match.
4. Check the server configuration: Occasionally, there may be some configuration issues with the server that cause the servlet to redirect to a JSP page with a blank screen. Try restarting the server or checking the server’s log files to see if there are any relevant error messages.

If none of the above methods work, you can try outputting some debugging information in JSP pages and servlets to further identify the cause of the error. Additionally, you can also try looking at detailed network request and response information in the browser’s development tools to see if you can pinpoint the issue.
