The problem is that when we are going to update the database it shows an error. Please get in touch with me if you are able to help as well as how much you would charge to repair. Here is the error 500 Servlet Exception [show] java.lang.NullPointerException java.lang.NullPointerException at com.edit.EditComIntro.doGet(EditComIntro.java:183) at javax.servlet.http.HttpServlet.service(HttpServlet.java:114) at javax.servlet.http.HttpServlet.service(HttpServlet.java:91) at com.caucho.server.dispatch.ServletFilterChain.doFilter(ServletFilterChain.java:103) at com.caucho.server.webapp.WebAppFilterChain.doFilter(WebAppFilterChain.java:187) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:265) at com.caucho.server.hmux.HmuxRequest.handleRequest(HmuxRequest.java:436) at com.caucho.server.port.TcpConnection.run(TcpConnection.java:682) at com.caucho.util.ThreadPool$Item.runTasks(ThreadPool.java:730) at com.caucho.util.ThreadPool$Item.run(ThreadPool.java:649) at java.lang.Thread.run(Thread.java:619 Code (markup): )
it has nothing to do with javascript, the error is in Java code that runs on server, I dont see anything database related either. there problem is in EditComIntro servlet, open EditComIntro.java file and look whats going on at line #183
