I am getting a NullPointerException on the following line:
originalStrutsPortletAction.processAction(
originalStrutsPortletAction, portletConfig, actionRequest,
actionResponse);
I am printing all the values:
System.out.println(originalStrutsPortletAction);
System.out.println(portletConfig);
System.out.println(actionRequest);
System.out.println(actionResponse);
Output:
com.liferay.portal.struts.StrutsPortletActionAdapter#2f20c4be
com.liferay.portlet.PortletConfigImpl#5f4268dd
com.liferay.portlet.ActionRequestImpl#1054ae1e
com.liferay.portlet.ActionResponseImpl#27733bf2
So why am I getting NullPointerException? Please help.Thanks in advance.

Simple answer: You don't get a NullpointerException at that location- at least not according to the stacktrace you post. Liferay's LoginAction does not have an originalStrutsAction. In case you're using 6.2 GA5, this is the code that throws the NullpointerException. Why? That's not what you asked.
Or, to phrase it differently: You're getting a NullpointerException because you dereference a Nullpointer. You'll just need to identify where you actually get it. The stacktrace helps. Who knows what your ExampleLoginAction does before it calls the line that you're posting...

I have facing "NullPointerException" in code. We have already check not null, but it's not working for us in the below screenshot. I already check folderInfoData.getSelectedInfoRole() != null but its enter to the if statement. It's private SelectOption<String> selectedInfoRole; type.
How to fixed this issue?

Here is Screenshot:
My guess is that you have a NullPointerException because either folderInfoData.getFolderprocessInforecord() or folderInfoData.getSelectedInfoRole().getValue() returns null and then you call getInfoValue on it.
To help debugging similar issues, try to keep lines simpler:
infoRole = folderInfoData.getSelectedoInfoRole().getValue();
infoRecord = folderInfoData.getFolderprocessInforecord().getValue();
if (!infoRole.equals(infoRecord) {
...
}
This would report a NullPointerException on the second line and would save you some time debugging.
I am using Struts 1. I need to send Vector of Objects from one Action to another throuh jsp.
In Action1:
Defined Vector Vector<UserObject> allEligibleUserList = new Vector<UserObject>();
and after adding objects request.setAttribute("elligible", allEligibleUserList);
In jsp:
<html:hidden property="userVector" value="${elligible}" />
In Form:
private Vector<UserObject> userVector;
public Vector<UserObject> getUserVector() {
return userVector;
}
public void setUserVector(Vector<UserObject> userVector) {
this.userVector = userVector;
}
In Action2:
Vector<UserObject> elligibleUserVector = catalogForm.getUserVector();
But I am getting the following error:

What am I doing wrong and how do I fix this?
Request attributes accept only String or String arrays.
So to transfer data from one action to another through a jsp, you should set it as a session attribute like this:
request.getSession().setAttribute("elligible", allEligibleUserList);
and in the next action class get the attribute and delete it like this:
Vector<UserObject> elligibleUserVector = (Vector<UserObject>) request.getSession().getAttribute("elligible");
request.getSession().removeAttribute("elligible");
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
