when I try to display employee.jsp page I am not able to select employee.
It looks like SelectOneMenu doesn't work. Am I missing something in that tag (line 20)?
I checked and the database has table employee with some employee data.
I have connection to database. I use mysql database. You can see connection to this database in persistance.xml file.

you should add the value to the selectOneMenu, the valueChangeListener attribute accepts a method-binding expression representing a value change listener method to be notified when a new value has been set for this input component. A value change listener method must be a public method that takes a ValueChangeEvent parameter, with a return type of void. It's not the same as the value property.
Your page.
<h:selectOneMenu id="selEmpNo"
valueChangeListener="#{employee.employeeReport}"
onchange="submit()" value="#{employee.myvalue}">
<f:selectItem itemLabel="select" />
<f:selectItems value="#{employee.empNoList}" id="emp"/>
</h:selectOneMenu>

It looks like basical, but I am new with Struts2.
I want to send a new product created with name, price and category.
I work with struts2 version 2.5.26, Maven, tomcat 9.0, java jdk 1.8.0_241
It seams that the code I use to send the product is wrong, and Action defined in struts.xml can't get it.
My JSP file to send the product :
<%# page pageEncoding="UTF-8" %>
<%# taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

<select id="cat" name="produit.categorie" class="formH len150">

I tried some other solutions but the best I get is a product with nom=null, prix=null, categorie=null.
I guess my problem is in these files.
I may send you the other files or methods

First of all I agree with #Aleksandr M, this is a very bizarre structure. But nevertheless, there are a few things wrong with this code.
1) You are returning 'success' result from action methods, so your result should be <result name="success">/companydetails.jsp</result>
2) You are storing Company object in local variable(Company viewCompany). This will not be available in your JSP.
What you should do is make a object variable. Add setter-getters for that variable and use it in your JSP as follows.
<s:property value="viewCompany.zipcode"/>
Hope this helps.
I have this action:
package com.test;
import com.opensymphony.xwork2.Action;
public class TestAction implements Action{
private String simpleParam;
public String getSimpleParam() {
return simpleParam;
}
public void setSimpleParam(String simpleParam) {
this.simpleParam = simpleParam;
}
#Override
public String execute() throws Exception {
return SUCCESS;
}
}
When it's executed I want to invoke another action inside struts(e.g. not redirect) and pass to it simpleParam. SecondAction is:
package com.test;
import com.opensymphony.xwork2.Action;
public class HelloAction implements Action {
private String id;
private String result;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getResult() {
return result;
}
#Override
public String execute() throws Exception {
result = "result" + getId();
return SUCCESS;
}
}
I saw working example when in struts.xml in result simply typed another action name and params and it worked. So I'm trying to do this:
<struts>
<package name="main" extends="struts-default">
<action name="test" class="com.test.TestAction">
<result name="success">hello.action?id=${simpleParam}</result>
</action>
<action name="hello" class="com.test.HelloAction">
<result>/hello.jsp</result>
</action>
</package>
</struts>
Idea totally sees this action but in browser I get 404 status. When I simply invoke hello.action from browser it works. Redirect also works. I also tried chain, but my param wasn't passed and it's not very convinient.
Am I doing it right? And if so what could be the cause of 404 status?
this could be helpful: http://struts.apache.org/docs/action-chaining.html
<struts>
<package name="main" extends="struts-default">
<action name="test" class="com.test.TestAction">
<result name="success" type="chain">hello</result>
</action>
<action name="hello" class="com.test.HelloAction">
<result>/hello.jsp</result>
</action>
</package>
</struts>
to pass a parameter from one action to another you could use the HttpServletRequest
(http://www.mkyong.com/struts2/how-to-get-the-httpservletrequest-in-struts-2):
TestAction.java:
package com.test;
import com.opensymphony.xwork2.Action;
public class TestAction implements Action{
private String simpleParam;
public String getSimpleParam() {
return simpleParam;
}
public void setSimpleParam(String simpleParam) {
this.simpleParam = simpleParam;
}
#Override
public String execute() throws Exception {
HttpServletRequest request = ServletActionContext.getRequest();
request.setAttribute("id", simpleParam);
return SUCCESS;
}
}
HelloAction.java:
package com.test;
import com.opensymphony.xwork2.Action;
public class HelloAction implements Action {
private String id;
private String result;
public String getId() {
return id;
}
public String getResult() {
return result;
}
#Override
public String execute() throws Exception {
HttpServletRequest request = ServletActionContext.getRequest();
id = (String)request.getAttribute("id");
result = "result" + getId();
return SUCCESS;
}
}

for delete action
<s:param name='ID'><%=user.getID()%></s:param></s:url>">Delete
Inside view method you haven't initialized the dao object(i.e reference is null), add the following code :
In TestIUE.java add one more member variable :
List<UseBean> users = new ArrayList<UseBean>();
Also add Accessor method :
public List<UseBean> getUsers()
{
return users;
}
Now modify your view method as follows :
public String view()
{
dao = new UseDao();
users = dao.getAllUsers();
return ActionSupport.SUCCESS;
}

How to retrieve the data from the database when the user clicks on the retrieve button, and display all the records in another HTML form?
Please give suggestions on how to do it.
In my application, when the user clicks the retrieve button it is performing the insert operation.
But I want is, when the user clicks it should go to the another page and display the data in table from database.
Can anybody tell the mistake what I have done, and give suggestions for finding solution for it and how to display the dynamic table in other page when the user clicks the retrieve button?
Finally I have done it, Now I am able to perform both insertion and retriving of data from database using jersey(JAX - RS) webservices and able to display it in a html page.
