[SOLVED] Uploaded file details on same page in Struts 2

Uploaded file details on same page in Struts 2

I can upload file using Struts 2. But I want to display details (Filename, filesize, filetype) about uploaded file in Struts 2.

I am trying to get details using <s:property value="myFile" /> tag, but it's always displays [Object HTMLDocument].

My code is following.

uploadfile.jsp:

    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
                pageEncoding="ISO-8859-1"%>
            <%@ taglib prefix="s" uri="/struts-tags"%>
            <!DOCTYPE html>
            
            <html>
            <head>
                <meta charset="utf-8">
                
            </head>
            <body>
                <div id="success-image">
                 <s:property value="myFile" />
            <s:head theme="ajax" />
                <s:form id="asset-upload"  name="asset-upload" action="uploadFile.action" method="POST"  theme="ajax" enctype="multipart/form-data">
                <s:file name="myFile" label="Upload Image"/>
       <s:submit targets="success-image" showLoadingText="false" indicator="uploading-image" id="asdf"/>
    </s:form>
        </div>
            </body>
            </html>

struts.xml:

    <?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">

                    <param name="myFile">myFile</param>
                 </result>
                <result name="error">login.jsp</result>
            </action>
            
            <action name="autoCompleterList" class="com.isam.struts.AutoCompleterList">
                <result type="json" />
            </action>
        </package>
    </struts>

UploadFile.java:

        package com.isam.struts;
        
        import java.io.File;
        import java.io.IOException;
        
        import org.apache.commons.io.FileUtils;
        
        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:/temp/";
        
                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;
            }
        
        }

So what should I need to add in JSP file to show details, and what should I need to add in struts.xml file?

Solution

To show file details on the same page after uploading it change your action result to:

<action name="uploadFile" class="com.isam.struts.uploadFile">
   <result name="success">uploadfile.jsp</result>
   <result name="error">login.jsp</result>
</action>

And in JSP use <s:property> tag to display values:

<s:property value="myFile.length()"/>
<s:property value="myFileContentType"/>
<s:property value="myFileFileName"/>
