    Default Re: Not able to inser data in mysql database

    Are there any errors (this is a servlet, so does the errors stream of the container show any errors)?

    Sounds like you are referring to the servlet output - any exceptions thrown and the output goes to stderr which is the servlet container (eg server) stderr which you will not see in the Servlet output. Look at that stream, or write something to the Servlet PrintStream (out) to debug and verify no exceptions are being caught.
