Don't use s:action tag in JSP, until you know how and why to do that. To display values in JSP you are not needed it at all. You should use struts tags to access action bean properties. For example you can print values to the JSP out using s:property tag. For example
<s:iterator value="beans">
id: <s:property value="id"/><br>
Book: <s:property value="book"/><br>
Author: <s:property value="author"/><br>
Availbleqty: <s:property value="availbleqty"/><br>
Category: <s:property value="category"/><br>
<s:/iterator>
The FilterDispatcher is deprecated and you should replace it with StrutsPrepareAndExecuteFilter. See web.xml docs. Also see this answer for
Need suggestions regarding project implementation in Struts and Hibernate.
Change your web.xml and stuts.xml as below.
Struts.xml
<struts>
<constant name="struts.devMode" value="true" />
<package name="a" namespace="/" extends="struts-default">
<action name="" class="Action.ActionTest" method="viewbookaction">
<result name="success">/BookView.jsp</result>

That's all. Simply run.

Interceptor product :
public class ProductCustomInterceptor implements Interceptor
{
private static final long serialVersionUID = 1L;
#Override
public String intercept(ActionInvocation invocation) throws Exception
{
System.out.println("ProductCustomInterceptor intercept() is called...");
System.out.println(invocation.getAction().getClass().getName());
return invocation.invoke();
}
}
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?
Although it is a common problem but I cannot figure it out.
I am running Strut2 with maven project. My project structure is given bellow
is
Product.java
package beans;
public class Product {
private int id;
private String name;
private float price;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public float getPrice() {
return price;
}
public void setPrice(float price) {
this.price = price;
}
}
ProductAction.java
package actions;
import beans.Product;
public class ProductAction{
public Product getProduct() {
return product;
}
public void setProduct(Product product) {
this.product = product;
}

public String execute(){
return "success";
}

I am using Glassfish server. It runs index.jsp well. But when I fill the form and submit it shows
HTTP Status 404 - There is no Action mapped for namespace [/] and
action name [product] associated with context path [/deploytest].
type Status report
messageThere is no Action mapped for namespace [/] and action name
[product] associated with context path [/deploytest].
descriptionThe requested resource is not available.
GlassFish Server Open Source Edition 4.1.1
My pom.xml has dependency
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.3.28</version>
</dependency>
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;
}
}

im new to struts2 so please help me to solve this.
I am working with Spring and I have a problem with a bean, here is my code:
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.grh.bo.ICollaborateurBo;
import com.grh.bo.IUserBo;
import com.grh.entities.Collaborateur;
#Component
#Scope("session")
public class CollaborateurBean implements Serializable {
private static final long serialVersionUID = 1L;
#Autowired
private ICollaborateurBo collaborateurBo;
private String nom;
private String prenom;
private String sflag = "";
private int currentProjectIndex;
private int page = 1;
public List<Collaborateur> listOfCollaborateur = new ArrayList<Collaborateur>();
private Collaborateur Collaborateurr = new Collaborateur();
List<Collaborateur> lis = new ArrayList<Collaborateur>(collaborateurBo.getAllCollaborateur());
#PostConstruct
public void init() {
setListOfCollaborateur(recupererCollaborateur());
Collaborateurr=new Collaborateur();
}
public List<Collaborateur> getLis() {
return collaborateurBo.getAllCollaborateur();
}
public void setLis(List<Collaborateur> lis) {
this.lis = lis;
}
public List<Collaborateur> getCollaborateurList() {
return collaborateurBo.getAllCollaborateur();
}
private List<Collaborateur> recupererCollaborateur() {
List<Collaborateur> ps = collaborateurBo.getAllCollaborateur();
return ps;
}
public CollaborateurBean() {
super();
}
public CollaborateurBean(ICollaborateurBo collaborateurBo, String nom,
String prenom, String sflag, int currentProjectIndex, int page,
List<Collaborateur> listOfCollaborateur,
Collaborateur collaborateurr, List<Collaborateur> lis) {
super();
this.collaborateurBo = collaborateurBo;
this.nom = nom;
this.prenom = prenom;
this.sflag = sflag;
this.currentProjectIndex = currentProjectIndex;
this.page = page;
this.listOfCollaborateur = listOfCollaborateur;
Collaborateurr = collaborateurr;
this.lis = lis;
}
public Collaborateur getCollaborateurr() {
return Collaborateurr;
}
public void setCollaborateurr(Collaborateur collaborateurr) {
Collaborateurr = collaborateurr;
}
public List<Collaborateur> getListOfCollaborateur() {
return listOfCollaborateur;
}
public void setListOfCollaborateur(List<Collaborateur> listOfCollaborateur) {
this.listOfCollaborateur = listOfCollaborateur;
}
public String getSflag() {
return sflag;
}
public void setSflag(String sflag) {
this.sflag = sflag;
}
public void setCollaborateurBo(ICollaborateurBo collaborateurBo) {
this.collaborateurBo = collaborateurBo;
}
public ICollaborateurBo getCollaborateurBo() {
return collaborateurBo;
}
public int getPage() {
return page;
}
public void setPage(int page) {
this.page = page;
}
public int getCurrentProjectIndex() {
return currentProjectIndex;
}
public void setCurrentProjectIndex(int currentProjectIndex) {
this.currentProjectIndex = currentProjectIndex;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
}
in this page collaborateur.xhtml i Can't display data from my DATABASE collaborateur.xhtml:
<h:dataTable value="#{CollaborateurBean.getLis()}" var="item">
<h:column>
<h:outputText value="#{item.nom}" />
</h:column>
<h:column>
<h:outputText value="#{item.prenom}" />
</h:column>
</h:dataTable>
When I test the collaborateurBo i display data from my DATABASE. This is the code that gives data from database:
<h:dataTable value="#{collaborateurBo.getAllCollaborateur()}" var="item">
<h:column>
<h:outputText value="#{item.nom}" />
</h:column>
<h:column>
<h:outputText value="#{item.prenom}" />
</h:column>
</h:dataTable>
This means that the problem is in the Collaborateur bean not in collaborateurBo or CollaborateurDao.
