Hello Community.
I am trying to upload a file (image/txt/word/pdf) in the ofbiz application
using ftl and java method. After parsing the file , item listed in the list is
coming as null. Please help.
My FTL code is a simple form like below with name testUpload.ft
<form action="uploadFile" method="post" enctype="multipart/form-data">
<input type="file" name="file" />
<input type="submit" value="Upload" />
</form>
My controller is configured as follows:
<request-map uri="fileUplodingFtl">
<security https="true" auth="true"/>
<response name="success" type="view" value="fileUplodingFtl"/>
</request-map>
<view-map name="fileUplodingFtl" type="screen"
page="component://xerus/widget/XerusScreens.xml#fileUplodingFtl"/>
<request-map uri="uploadFile">
<security https="true" auth="true"/>
<event type="java" path="com.apache.xerus.services.FileUpload"
invoke="uploadFile"/>
<response name="success" type="view" value="fileUplodingFtl"/>
</request-map>
In the java class FileUpload.java:
package com.apache.xerus.services;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;

public class FileUpload {
public static final String module = FileUpload.class.getName();
public static String uploadFile(HttpServletRequest request,
HttpServletResponse response) {
// Check if the request is a multipart request
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
if (isMultipart) {
// Create a file upload handler
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
try {
// Parse the request
List<FileItem> items = upload.parseRequest(request);
System.out.println(" Items present : "+items);
// Process each uploaded file
for (FileItem item : items) {
if (!item.isFormField()) {
// Get the uploaded file name
String fileName = item.getName();
System.out.println("fileName : "+fileName);
// Get the uploaded file content
byte[] fileContent = item.get();
System.out.println("fileContent : "+fileContent);
// Process the file as needed (e.g., save to disk,
store in database, etc.)
// ...
}
}
} catch (FileUploadException e) {
Debug.logError(e, module);
Debug.logError("[FileUpload.FileUpload] " + e.getMessage(),
module);
}
} else {
System.out.println("It is not multipart");
}
I have added the screen in XerusSceen.xml and logging in the app by typing
localhost:8443/xerus/control/fileUplodingFtl and the page is opening but when I
am selecting the file and pressing the Upload button, I can see in the logs of
ofbiz as ' Items present: {} '. I am wondering , what is wrong with this
code? Why is there no file present
Please guide me how to achieve uploading of files in OFbiz
Thank You
Regards,
Swati
