I'm connecting Eclipse and MySQL by using tomcat. But I got some error while running the project on Eclipse.
Running http://localhost:8080/webserver/ is OK. But it's not OK on http://localhost:8080/webserver/ListServlet. I've already try method to set utf-8, but it's not working.

I've installed ProjectForge successfully but after some time tomcat starts pausing I found out the following under logs. I'm using XAMPP.
I assumed it was due to port conflict I have changed the port but I need to know the root cause.

I seem to have found the cause of the issues. There are bugs with services provided by ProjectForge. When ever those services are called it ends up throwing error.
The Java/Servlets/JasperReports based application was working fine before, but now not showing the PDF report and throws java.lang.ClassNotFoundException
I use the libraries:
commons-collections-3.2.1.jar
commons-digester-1.7.jar
commons-logging-1.1.3.jar
iText-2.1.7.js2.jar
jasperreports-5.2.0.jar

With commons-collections.jar should be enough, check that you have the jar on WEB-INF/lib of your web application
Here I have written some code for retrieve the values from database passing some values.
Below is the Action class code:
AttendenceServiceImpl serveceimpl;
public ActionForward getStudentInfo(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response) {
System.out.println("-----------------getStudentInfo Start----------------------");
String category = request.getParameter("categoryVal");
String classId = request.getParameter("classidVal");
String sectionId = request.getParameter("sectionidVal");
System.out.println("----"+category+"---"+classId+"---"+sectionId);
serveceimpl.getStudentinfo(category,classId,sectionId);
Here Category, classid and section values are coming.
And I'm calling method of service class from Action class.
Below is the Service class code:
public List getStudentinfo(String category, String classId, String sectionId) {
System.out.println("------------getStudentinfo SERVICE START---------------------");
List data=mainpage.getStudentinfo(category, classId, sectionId);
System.out.println("------------getStudentinfo SERVICE END---------------------");
return data;
}
But in Action class I'm getting NullPointerException before control enter into the Service class.
Below is the StackTrace:
-----------------getStudentInfo Start----------------------

Please give me the solution it is helpful for me.
serveceimpl should be null here. Please check whether it has a valid value in it. See below
You haven't initialized it
AttendenceServiceImpl serveceimpl;
I have seen a lot of questions about this issue, but no solution suits for me. Also I get this error only if I try to persist object. I am getting following error
java.lang.IllegalArgumentException: Object: com.test.entity.ReminderConfiguration#5d035a33 is not a known entity type.
