PostgreSQL connection in Java Servlet to Retrieve Information from the DB. Getting Error

Question

I am having difficulty with getting this work. I can connect to the database without problem, however I can not make it show me the html page. It does not run.

Answer 1

Seem you did't add Postgresql JDBC driver into classpath, as the following error suggest:

javax.servlet.ServletException: Class not found Error

Which is origin from:

throw new ServletException("Class not found Error");

You can download Postgresql JDBC driver and put in PROJECT/WEB-INF/lib folder.

Suggestion

One suggestion, your exception handling is wrong, you should change

throw new ServletException("Class not found Error");

to

throw new ServletException("Class not found Error", e);
