Why do I often get exceptions when uploading files using "multipart/form-data"? [duplicate]

Problem: Only server side file id validation is not working. Even if I selects a file its also showing validation message File is required. Remaining validations are working perfectly. Here I'm placing some stuff. Before its worked. After restarting my server this validation not working.

You have used wrong validator. "requiredstring" validator is used to validate textfields. You can use "required" validator that validates the field to be not null.
<field name="id">
<field-validator type="required">

Interceptor product :

How can I intercept all filed value of my class product when I click save button in my jsp page by using interceptor class with debugging mode browser?

HIbernate saveorUpdate() inserting new records while updating

I am using struts2 and hibernate Integration by following this link http://www.tutorials4u.net/struts2-tutorial/struts2_crud_example.html and trying to update the records but instead of updating it is inserting new records , I have seen all the hibernate update questions before posting this post but none of them worked for me so Please I am requesting to read my question before marking it as duplicate, as I had tried a lot from the already posted questions and answers...

Please help Me... As I tried all ways whether it is of using session.flush() or deleting #GeneratedValue annotation
Id not coming in addStudent()
public String editStudent() {
HttpServletRequest request = (HttpServletRequest) ActionContext
.getContext().get(ServletActionContext.HTTP_REQUEST);
dao.listStudentById(Integer.parseInt((request.getParameter("id")))); return SUCCESS;
} //AddStudetnAction class method
public void addStudent(Student student) {
try {
System.out.println(student.getId() + "In DAO addStudent");// returning null
session.saveOrUpdate(student);
} catch (Exception e) {
e.printStackTrace();
}
//StudentDAO class method
The addStudent() of StudentDAOis getting null value for id, how can I set the id for addStudent() so that it calls update method instead of save

After spending nearly 2-3 days, I got the solution, I mentioned the <s:hidden> tag in my JSP from where I am passing the id as
<s:hidden name="id" /> , in order to update the Hibernate should get the id and if it fails to do so it will call save method.

if you want to update record you need to have it's id, SaveOrUpdate looks for the id if it is in your table then it updates , if it is not then its add a new record.
I am not sure how you create your Student but if you want to update you need to get the object from the database to have the id ( or if you know the id just set it) then update what you want while the object is in the persistance context and flush.

Here is my edit method.
StudentAction.java
public String edit()
{
HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);
student = studentDAO.listStudentsById(Long.parseLong(request.getParameter("id")));
return SUCCESS;
}
StudentList.jsp
<s:url id="editURL" action="edit">
<s:param name="id" value="%{id}"></s:param>
</s:url>
<s:a href="%{editURL}">Edit</s:a>

The s:form tag doesn't let you to use any parameter in the URL, but you can use hidden input field. s:form tag defaults to POST method.
<s:form action="addStudent">
<s:actionerror />
<s:textfield name="firstName" label="First Name" />
<s:textfield name="lastName" label="Last Name" />
<s:textfield name="marks" label="Marks" />
<s:hidden name="id"/>
<s:submit value="Save" />
...
</s:form>

That using the stringlenth validator you can validate the length of the string. Check the stringlength validator.
And using the date validator you can validate the date format. Check the date validator.
If you want to validate datetime picker using validate() you should use the logic that is to parse the value returned by the picker using SimpleDateFormat if you are not using other date time libraries like JODA and don't care about timezone then you should create ThreadLocal parser for datetimes.

In Struts2 I am not getting form value on success.jsp page

In my application I am trying to register a user by adding his details to the database and after success fully insert these values. I need to display form input page but on result page I am not getting any output.
My ACTION CLASS IS
package action;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import dao.Empdao;
import model.Empmodel;
public class Empaction extends ActionSupport implements ModelDriven<Object>{
private static final long serialVersionUID = 1L;
Empmodel modelobj;
public Empmodel getModelobj() {
return modelobj;
}
public void setModelobj(Empmodel modelobj) {
this.modelobj = modelobj;
}
public String execute() throws Exception{
Empdao empdao = new Empdao();
int queryResult = empdao.registration(modelobj);
if (queryResult==0)
{
addActionError("it is a dublicate entry please enter anothe id");
return ERROR;
}
else{
return SUCCESS;
}
}
#Override
public Object getModel() {
modelobj = new Empmodel();
return null;
}
}
Success.jsp is
<body>
first name : <s:property value="modelobj.firstname"/> <br>
last name :<s:property value="modelobj.lastname" />
<s:property value="modelobj.id" />

You are redirecting the page on success that is wrong because you loose values needed to display results. Use
<result name ="success">/Registration/success.jsp</result>
or simply
<result>/Registration/success.jsp</result>
BTW, you only have getters & setters for firstname and lastname, so the only these properties will display. If you want to display other properties then you should add correcponding methods to fields.
You may read the servlet API javadoc to make clue what may cause result type="redirect".
For further compare the difference between forward and redirect results consider this thread.

If type=redirectAction then you have to mention the Action name without any extensions
if its only redirect then you have to mention including the action name and extension, For your Question it was because of redirect the problem happened.
Even after redirecting to some page and when you come back to the result page , and if you want to retain data then its better you better put in session .

Do not redirect you page remove it and use
<result name ="success">/Registration/success.jsp</result> in you struts.xml file
