I am new to struts2. What I am trying is to get data from the client and insert into the db.But while doing this setImageFile(File fie) isnt called and thus imageFile object is null. While other set methods are called and is thus respective members contains values.
action.class
import com.opensymphony.xwork2.ActionSupport;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.sql.*;
import java.util.Map;
import javax.servlet.http.Part;
import org.apache.struts2.interceptor.SessionAware;
import org.apache.struts2.dispatcher.SessionMap;
public class register extends ActionSupport implements SessionAware{
SessionMap<String, String> sessionMap;
private String name;
private String email;
private String dob;
private String address;
private File imageFile;
private String imageFileFileName;
private String imageFileContentType;
#Override
public void setSession(Map map)
{
sessionMap = (SessionMap)map;
sessionMap.put("", name);
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getDob() {
return dob;
}
public void setDob(String dob) {
this.dob = dob;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public File getImageFile() {
return imageFile;
}
public void setFile(File imageFile) {
this.imageFile = imageFile;
}
public void setSessionMap(SessionMap<String, String> sessionMap) {
this.sessionMap = sessionMap;
}
public String execute()
{
try
{
Class.forName("org.postgresql.Driver");
Connection conn=DriverManager.getConnection("jdbc:postgresql://localhost:5432/DemoDB", "postgres", "postgres");
InputStream imageInputStream = new FileInputStream(imageFile);
String query = "insert into userProfile('Name','Address','email','dob','img') values(?,?,?,?,?)";
Date date = Date.valueOf(dob);
PreparedStatement preparedStatement = conn.prepareStatement(query);
preparedStatement.setString(0, name);
preparedStatement.setString(1, address);
preparedStatement.setString(2, email);
preparedStatement.setDate(3, date);
preparedStatement.setBinaryStream(4, imageInputStream, imageFile.length());
preparedStatement.execute();
}
catch(Exception e)
{
System.out.println(e.getMessage());
}
return "success";
}
}
In the above code imageFile is null. And othe members contains value
struts.xml

<put-attribute name="title" value="Passport seva registration"/>
<put-attribute name="body" value="/registration.jsp"/>
</definition>
</tiles-definitions>
The output says that invalid field value for imageFile.
Use Struts Form tag with enctype attribute.
<s:form action="register" method="POST" enctype="multipart/form-data">

Once you specify any interceptors you must specify all interceptors.

It works fine with the project where i have jsf 1.2 but when i add this to a new project with jsf 2.2 it shows the error
I also configured all the setting for Struts2 basic validation, but nothing is working for me.
My login.jsp file

My loginAction class is,
package com.test;

public class LoginAction extends ActionSupport {
private static final long serialVersionUID = 1L;
private String userName;
private String password;

my struts2.xml file is,

<action name="Login" class="com.test.LoginAction" method="execute">
<result name="SUCCESS">login.jsp</result>
<result name="input">login.jsp</result>
</action>
</package>
</struts>
And I place my LoginAction-validation.xml file in the same package where the Action class is placed.
Please lookout my code and help me to resolve the validation issue.
You are returning same login.jsp page in your execute method in action class.
So this results in displaying login page with empty field every time you hit enter.
Try creating an additional jsp to which you are redirected to based on String returned from action class.
other than that i dont see any problem.
i am not able to get the value of the text entered in the textbox in jsp into my action class. below are my files. can anyone please help as this is very urgent.
my jsp is
<%# taglib uri="/struts-tags" prefix="s" %>

<s:submit type="button" id="submit" label="Submit"/>

my action class is

}
public void setUsername(String username) {
this.userName = username;
}
public String execute(){
System.out.println("the userName is "+this.getUserName());
return SUCCESS;
}
}
and my struts.xml is
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

<result name="success">/webpages/home/Home.jsp</result>
</action>
</package>
</struts>
Case-sensitivity is important.
public void setUsername(String username) {
this.userName = username;
}
Should be:
public void setUserName(String username) {
this.userName = username;
}
In your struts.xml, you have written
class="core.login.LoginAction"
but you are not declaring any package in your Action class.
Also setter and getter method are of different names. Remember they are case-sensitive as said by Steven.
Try removing minor mistakes like an extra ">"
In your textfield add value attribute like this:
<s:textfield name="userName" label="User Name" value="${userName}" />
That directly maps it to member variable in action class.
In Eclipse,
to solve case sensitivity problem right click on code writing area and go to source -> Generate getter and setter method
It will add getter and setter method for selected member variables.
