I am trying to learn Struts2, I have used a view page that hits action , the action class is using a bean where getter setter methods are written and the action is also using a dao where the connection is written.I want to mention that I am using jboss v5.0 and eclipse, I have added all the jar files.
Now , when I am trying to run this application the welcome jsp page is hitting properly then on clicking submit button the below error is showing:
There is no Action mapped for namespace /controller and action name
I am placing my code and directory structure. I have tried the using namespace="/"
<result name="SUCCESS">/success.jsp</result>, still its is not working

This error
There is no Action mapped for namespace /controller and action name
generally means Struts can't find the action specified in a namespace specified (/controller in this case). BTW in your case you've not specified /controller anywhere and the action name is missing in the error message, so this error could be probably generated by the bunch of other errors you have in your action / JSP / configuration.
you also have two typos, preventing anything to work:
sturts-default instead of struts-default:
<package name="default" extends="struts-default">
"SUCCESS" instead of "success", that is the result mapped to the constant SUCCESS that you are returning from the Action method.
<result name="success">/success.jsp</result>
If using Struts version newer than or equals to 2.1.3, you need the new filter, StrutsPrepareAndExecuteFilter instead of the deprecated FilterDispatcher;
The action method must be a public String something() with no parameters. This:
public String execute(HttpServletRequest request , HttpServletResponse response) throws Exception
is simply wrong, and should be:
public String execute(){}
Here
String Name = request.getParameter("Name");
String Age = request.getParameter("Age");
String Location = request.getParameter("Location");
TestBean bean = new TestBean();
bean.setName(Name);
bean.setAge(Age);
bean.setLocation(Location);
you are reinventing the wheel really badly. Attributes must be private, at class level, with getters and setters, and they'll be populated automatically, with no need to access the request. In your case:
private TestBean bean;
/* GETTER AND SETTER */
public String execute(){
System.out.println(bean.getName());
// ...
}
Unrelated, but Java naming conventions use lower-case names for local variables and instance properties.
In JSP page, you need to access the getter with a starting lowercase character:
<s:textfield name="Name" label="Name"/>
must be
<s:textfield name="name" label="Name"/>
and so the other fields. Also if you point to an object like TestBean, you need to do like this:
<s:textfield name="bean.name" label="Name"/>
This are the main problems... BTW consider start coding after having read a book, or some good tutorial. Starting in the dark like this is not the right way, IMHO.
Following are points which you should notice,
If you are using TestBean class as data carrier, you have to implement ModelDriven Interface.
TestAction.java should present in "Controller" package.
If you want HttpServletRequest and HttpServletResponse in your execute() method, then the simplest way you can get that is to implement ServletRequestAware and ServletResponseAware interfaces and implement respective methods.
And most important if your success.jsp is in Web Content folder, then you dont need to specify
<result name="SUCCESS">/success.jsp</result>
Just make it like
<result name="SUCCESS">success.jsp</result>
And if you have any folder suppose, "Folder1" in Web Content, Then specify like
<result name="SUCCESS">Folder1/success.jsp</result>

When I am using Model driven interface, my file upload operation is not working.
It is not popping any error, nor it is generating any log.
My code is attached hereby,
I want to know for file, do we have to generate its getters/setters in Model or Action with Model-Driven interface.
Atleast it should get uploaded to temp folder, as with struts by default uploads to temp.

Of,course,your file upload operation can working When you using Model
driven interface but you made a few mistake:
public class FileUploadModel {
private String employeeName;
private File image;
private String imageFileName;
// YourCode was wrong : private String imageFileCotentType;
private String imageFileContentType;
(get set)...
And then,you need to add a piece of code to your code for upload like
this:
#Namespace("/")
#ParentPackage("struts-default")
public class FileUploadAction extends ActionSupport implements ModelDriven<FileUploadModel> {
private static final long serialVersionUID = 1L;
FileUploadModel fileModel = new FileUploadModel();
#Override
public FileUploadModel getModel() {
return fileModel;
}
#Action(value = "submitForm", results = {
#Result(name = "success", location = "/result.jsp") })
public String submitForm() {
HttpServletRequest request = ServletActionContext.getRequest();
String tomcatPath = ServletActionContext.getServletContext().getRealPath("/");
String projectName = request.getContextPath();
projectName = projectName.substring(1);
String filePath = tomcatPath.substring(0, tomcatPath.indexOf(projectName)) + "uploadFile";
File dest = new File(filePath, fileModel.getImageFileName());
try {
FileUtils.copyFile(fileModel.getImage(), dest);
} catch (IOException e) {
e.printStackTrace();
}
return "success";
}
}
if you implements the function based on my answer,please reply to
me,smile.
I have index.jsp where I have one link,on clicking on that link that page specific action gets called.Now as on the click of this link,I need to display a page with already populated multiselect list along with few input text fields,in the constructor of the action I populated the TransactionBean which will be bound with fields on next page i.e transactionData.jsp.
The transactionData.jsp page is getting displayed correctly with populated multiselected list.Now user can select values from multiselect list and can enter dates in text field and will click on click button,so that a bar chart is displayed.
On click on Click button ,I am calling another action ,which also has TransactionBean as its property.In the execute method of this action, I am trying to access transactionbean with its getter but it gives me NullPointerException. I got to know that, if we are submitting a page which has fields of bean binded ,then on calling action,bean will be instantiated automatically through interceptors but seems like something is not correct here.

Always use the latest version. At the moment it's Struts 2.3.16.3 GA. You can also see Version Notes and Migration Guide.

When i submit the registration form , the input values pass to Action class is null. How can i access the registration values in action class under register() method.
The above issue is resolved .
Now i'm facing another strange issue .. When i submit the form action = getLogin.action , its always returning INPUT from the interceptor . I dont wish to exclude the method login from the validator.
How could i resolve it ?
When i change the struts xml like below , its redirecting to success jsp . But i dont want to exclude the login method from validation
<action name="getLogin" class="login.action.LoginAction"
method="login">
<interceptor-ref name="defaultStack">
<param name="validation.excludeMethods">login</param>
</interceptor-ref>
<result name="success">/Success.jsp</result>
<result name="input">/LoginError.jsp</result>
</action>
You are using only one Interceptor, you need to use the whole Stack:
Change this:
<interceptor-ref name="validation">
<param name="excludeMethods">register</param>
</interceptor-ref>
to this
<interceptor-ref name="defaultStack">
<param name="validation.excludeMethods">register</param>
</interceptor-ref>
I'm using Netbeans 7.2.1 and GlassFish 3.1.
I created web application using JSF, ejb classes and JDBC data source.
xhtml pages reference backing managed beans, which call local interface functions on ejb classes which run queries through the data source, directly getting connection and executing queries.
The project builds successfully, but when I run the project, browser shows error "No data received", and browser tab title says failed to load. I think maybe I have some missing configurations, cause when I run same project with no reference to managed beans (and hence not to ejb's and database) , there's no such message.
Frankly I got lost in what configuration files are needed for such a project, and what is needed to configure there. I saw numerous explanations, each saying something else, and I'm not clear which one is relevant here. If you could point me to some clear relevant explanation, I'd be grateful.
Do I need to configure for this project somewhere data source? ejb classes? anything else?

Thanks for the help!
The problem was SQLSyntaxErrorException. Just needed to look at server log (output tab , glassfish server tab) to see what was the problem. Fixing SQL syntax rendered the page correctly.
You are missing a space between Users and WHERE in your query. This is causing the query to be parsed as:
SELECT STATUS FROM UsersWHERE NAMEU ...............
