I am getting the following error whilst uploading a file.
The parameters dictionary contains a
null entry for parameter 'category_id'
of non-nullable type 'System.Int32'
for method
'System.Web.Mvc.ActionResult
AddProduct(Int32, System.String,
Single, System.String, System.String,
System.String, System.String,
System.String, System.String)' in
'Ecommerce.Controllers.AdminController'.
To make a parameter optional its type
should be either a reference type or a
Nullable type. Parameter name:
parameters
I am using a dialog box.
The View
<script type="text/javascript">
$(function() {
$("#dialog").dialog({
bgiframe: true,
height: 140,
modal: true,
autoOpen: false,
resizable: false
})
});
</script>
<div id="dialog" title="Upload files">
<% using (Html.BeginForm("Upload", "File", FormMethod.Post, new { enctype = "multipart/form-data" }))
{%>
<p><input type="file" id="fileUpload" name="fileUpload" size="23"/> </p>
<p><input type="submit" value="Upload file" /></p>
<% } %>
</div>
<p>
<label for="image_name">image_name:</label>
Upload File
<%= Html.ValidationMessage("image_name", "*") %>
</p>
The Controller Action
public ActionResult AddProduct(int category_id, string product_name, float product_price, string product_desc, string weight, string image_name, string img_content, string available_qty, string isFeature)
{
foreach (string inputTagName in Request.Files)
{
HttpPostedFileBase file = Request.Files[inputTagName];
if (file.ContentLength > 0)
{
string filePath = Path.Combine(HttpContext.Server.MapPath("../Uploads"), Path.GetFileName(file.FileName));
string filecontent = Path.Combine(HttpContext.Server.MapPath("../Uploads"), Path.GetFileName(file.ContentType));
image_name = Path.GetFileName(file.FileName);
img_content = Path.GetFileName(file.ContentType);
file.SaveAs(filePath);
}
}
AdminImplementation _adminImplementation = new AdminImplementation();
Boolean isfeature = Convert .ToBoolean(isFeature);
if (isfeature)
{
isFeature = "Featured";
}
else
{
isFeature = "NotFeatured";
}
int i = _adminImplementation.addproduct(category_id, product_name, product_price, product_desc, weight,image_name ,img_content ,available_qty ,isFeature );
ViewData["succm"] = "Product added successfully";
return View();
}
Please suggest some useful answers.
Thanks

Looks to me like you're not providing all the parameters required for a specific ActionResult. category_id isn't being provided to AddProduct. You'd need to show us your code for us to be able to find out what's really going wrong.
How are you calling that ActionResult?

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 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

The output says that invalid field value for imageFile.
Use Struts Form tag with enctype attribute.

I have a working action which is using the ExecAndWait Interceptor. My wait page is
<%# page language="java" pageEncoding="UTF-8" session="false"%>
<%# taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="2"/>"/>
</head>
<body>
<h3>Waiting</h3>
<div id="wait-result">
</div>
</body>
</html>
this is working correctly and adding a breakpoint to my action I can see that the action only gets invoked once regardless of the number of refreshes. As it should.
Now, if I remove the meta-refresh tag and replace it with a JQuery script to
reload the page, what I see is my action gets invoked for each request and the final result page never arrives.
<%# taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js" ></script>
<script>
var repeat = false;
function executeQuery() {
$.ajax({
type: 'GET',
url: 'search',
async: false,
success: function(data) {
if ($(data).find('#wait-result')) {
repeat = true;
} else {
repeat = false;
$('#wait-result').html(data);
}
}
});
if (repeat) {
setTimeout(executeQuery, 1000);
}
}
$(document).ready(function() {
setTimeout(executeQuery, 1000);
});
</script>
</head>
<body>
<h3>Waiting</h3>
<div id="wait-result">
</div>
</body>
</html>
Is it possible to use the ExecAndWait Interceptor with a JQuery Ajax call? If so, what am I doing wrong?
Regards

Ok, found it.
The problem was trying to parse the response to the GET request into an HTML object and then trying to run a selector.
Changing the line
if ($(data).find('#wait-result')) {
to
if (data.indexOf('#wait-result') >=0) {
fixes the problem and now everything runs as expected
I have created a form component. In that form component I also have a range component.
I was wondering how can I retrieve my value from my range component and more generally how can I interact with a component from outside it. (even if the goal is to encapsulate things)
I don't know if there are components like that somewhere but for now I just want to learn how it works. thanks !

I guess changing NgOneWay to NgTwoWay should do the trick so the value gets updated inside the component. To get the value outside of the component bind
<range name="years" value="{{myProp}}"></range>
and create a field in your my-form component.
#NgTwoWay('myProp')
var myProp;
Alternatively you can implement ScopeAware to get the scope and then use scope.emit, scope.broadcast, scope.on... to send the data as event on submit to send it across the DOM not just to the immediate parent/child
almost :) but it's only works one way
I initialize the property in my_form.dart then the my_form.html has the value binded and finally the range component can use the value at init time.
but when I change the code inside the component the value is not binded anymore with the my_form.dart
here is the code
range.html didn't change
my_form.dart
library my_form;
import "package:angular/angular.dart";
#Component(selector: "my-form", templateUrl: "my_form.html", exportExpressions: const ["submit"])
class DateFormComponent {
#NgOneWay("random")
bool random;
#NgTwoWay("v1")

submit() {
print(random);
print(v1);

bind(DateFormComponent);

addRange() {
ranges.add("$range_begin-$range_end");
range_begin = "";
range_end = "";
value = ranges.reduce((begin, item){

The critical part of your code is
<button jsf:id="login" disabled="#{complex.status}">Login</button>
and then this exception
java.lang.ClassCastException: java.lang.Boolean cannot be cast to java.lang.String
Now It mean for <button> tag, the value of disabled attribute is not boolean but a String.So the value of this attribute is disabled="disabled".Please see this question as well for handling the disabled attribute for HTML5
You need to set the String value from your managed bean and declare status property as a String rather than boolean.
i need file upload in strurts 2 and store it to server location,i used by googles no use, can anybody give better idea. advance thanks
To google, it might help to check what you type: it's "struts2", no "strurts"
Anyway, you dont need to google, the official docs are enough
http://struts.apache.org/2.2.1/docs/file-upload-interceptor.html
http://struts.apache.org/2.2.1/docs/handling-file-uploads.html
http://cwiki.apache.org/WW/file-upload.html
Here is whole code of struts2 file upload.
Action file (fileupload.java)
package com.tutorialspoint.struts2;
import java.io.File;
import org.apache.commons.io.FileUtils;
import java.io.IOException;
import com.opensymphony.xwork2.ActionSupport;
public class uploadFile extends ActionSupport{
private File myFile;
private String myFileContentType;
private String myFileFileName;
private String destPath;
public String execute()
{
/* Copy file to a safe location */
destPath = "C:/apache-tomcat-6.0.33/work/";
try{
System.out.println("Src File name: " + myFile);
System.out.println("Dst File name: " + myFileFileName);
File destFile = new File(destPath, myFileFileName);
FileUtils.copyFile(myFile, destFile);
}catch(IOException e){
e.printStackTrace();
return ERROR;
}
return SUCCESS;
}
public File getMyFile() {
return myFile;
}
public void setMyFile(File myFile) {
this.myFile = myFile;
}
public String getMyFileContentType() {
return myFileContentType;
}
public void setMyFileContentType(String myFileContentType) {
this.myFileContentType = myFileContentType;
}
public String getMyFileFileName() {
return myFileFileName;
}
public void setMyFileFileName(String myFileFileName) {
this.myFileFileName = myFileFileName;
}
