I have the struts2 checkbox which behavior strangely when there are previous and next paging situation.
I have the three pages jsp named step1.jsp, step2.jsp and step3.jsp
I have the checkbox control on step1.jsp.
<s:checkbox value="%{loanForm.directmarketingCheckboxboolean}" name="loanForm.directmarketingCheckboxboolean"
style="vertical-align:middle;" id="directmarketingCheckbox" />
private boolean directmarketingCheckboxboolean;
public boolean isDirectmarketingCheckboxboolean() {
return directmarketingCheckboxboolean;
}
public void setDirectmarketingCheckboxboolean(boolean directmarketingCheckboxboolean) {
this.directmarketingCheckboxboolean = directmarketingCheckboxboolean;
}
Load step1.jsp and checked the checkbox in step1 and clicked next button. It goes to step2.jsp.
In step2.jsp, click previous button. It goes to step1.jsp.
The checkbox in step 1 is checked. Then I unchecked it and click
next button. It goes to step2.jsp.
In step2.jsp, click previous button. It goes to step1.jsp.
The checkbox in step1 is still checked. (It should show unchecked.
Right?).
first step
second time after next and previous
third time

I have created a simple program that gets the firstname and lastname of a user using a textfield. But the problem is that when I click the submit button I cannot redirect it to another jsp file which shows the firstname and lastname of the user.
Here's my HelloAction class:
package com.novamsc.training.struts.action;
import com.opensymphony.xwork2.ActionSupport;
public class HelloAction extends ActionSupport {
private String firstName;
private String lastName;
public String user(){
return "hello";
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String display(){
return "hi";
}
}
Here's my userInput.jsp file:
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%# taglib uri="/struts-tags" prefix="s"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
<s:form name="inputData">
<s:textfield key="firstName"/>
<s:textfield key="lastName"/>
<s:submit/>
</s:form>

Here's my resultInput.jsp file:

Here's my struts-traning.xml file:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC

You should use form tag with additional attributes that map the form to another action.
<s:form name="inputData" namespace="/exercise" action="submitData">
<s:textfield key="firstName"/>
<s:textfield key="lastName"/>
<s:submit/>
</s:form>
then for additional action you need to write action config
<action name="submitData" class="com.novamsc.training.struts.action.HelloAction"
method="save">
<result type="redirectAction">inputData</result>
</action>
add additional method to map the new action
public String save(){
return ActionSupport.SUCCESS;
}
This additional action is required to follow PRG (Post-Redirect-Get) pattern.
I am learning Upload interceptor now.
The document says, all upload files size exceeds the value of constant "struts.multipart.maxSize" will throw a exception in the background, and the view will go to INPUT view.
But, in my case,it can not throw any exception, and the view did not go to INPUT view(Upload progress has been 0% always,see the picture).

My development environment：
eclipse4.5.1+tomcat8+jdk1.8+struts2.3.24
Why can not throw exception,why not go to Input view?
This is a known problem, analyzed in this answer, and (as you can read in the update), it's been "patched" in Struts2 2.3.18.
Just upgrade to 2.3.24.1 and use jakarta-stream as Multipart parser.
I have created Struts 2 database application. In this one using Query I made Ajax call to the Struts 2 action. The problem is whenever I hit the submit button, it will trigger the Ajax call, but Ajax call is not properly hit the server action class URL. Every time I got 404 exception in browser. How to resolve this problem?
this is my js file :
$(document).ready(function(e){
$("#loginPage_emailid").blur(function () {
console.log("OnBlur() EmailId");
var emailId=$("#loginPage_emailid").val();
console.log("emailId ------- "+emailId);
if(emailId != null && emailId.length != 0 && typeof emailId != 'undefined' && emailId != "InvalidEmailId"){
FormValidator.prototype.validateEmailId(emailId);
}
else{
$("#loginPage_emailid").val("InvalidEmailId");
return false;
}
});
$("#loginPage_emailid").click(function () {

There is no execute method in your LoginAction class, so AJAX call does not return any result. Try to add simple execute method:
public String execute() {
return SUCCESS;
}
404 is not an exception. It's an error code the Struts set to the response when no action found in the runtime configuration corresponding to the URL requested.
Because you didn't post a web.xml consider looking at Error 404 issues using Struts application.
Also check your library folder WEB-INF/lib for plugins you didn't use and remove them. Look at the issue at Struts2 - HTTP Status 404 - No result defined for action. You should post the stacktrace with exact error message however.
When calling an action from javascript code use s:url tag to build the action URL from the action mapping. See Jquery Error - While calling struts action.
The code you should change
$.ajax({
type: "POST",
url: '<s:url namespace="/" action="login"/>',
data: jsonData,
success: function(data){
console.log(""+data);
}
});
By the way if you are using struts2-jquery plugin there's a possibility to make ajax submit with <sj:submit> tag.
I have the following usecase that on Login a CustomerForm should be shown and a ListofCustomers which is retrieved from Database should be shown.

You can't pass a method as parameter name. This name is reserved for special parameter used by DMI and have a special syntax. First, if you want to use this parameter and DMI you should enable it.
<constant name="struts.enable.DynamicMethodInvocation" value="true" />
then
<result type="redirect">/customer?method:getCustomersList</result>
Note, use a colon to specify a method name in parameter.
or use equivalent syntax
<result type="redirect">/customer!getCustomersList</result>
You might also wonder: Is a colon safe for friendly-URL use?
Also, don't use .action extension in the struts tags
<s:form namespace="/" action="customer" method="post" validate="true">
<s:textfield name="name" key="name" size="20" />
<s:textfield name="age" key="age" size="20" />
<s:textfield name="email" key="email" size="20" />
<s:textfield name="telephone" key="telephone" size="20" />
<s:submit method="addCustomer" key="label.add.customer" align="center" />
</s:form>
Note, the method attribute used by the struts tag to add a special parameter to the form url: method:addCustomer. This parameter only works with DMI. If you used namespace to the action configuration you should use it in the form tag as well.
