apache-commons-fileupload

问题 I'm trying to upload files to Google Drive with ProgressListener and ChunkSize enabled (thus with DirectUploadEnabled disabled). This way i have a more reliable upload and the possibility for a progress indication to the user. I transfer the files from the GWT website to the GAE with a FormPanel and a FileUploadField which POSTS the file to GAE on submit(). On the GAE i receive the file with an UploadServlet which uses org.apache.commons.fileupload to receive the documents as a stream. I don

问题 I am writing some code to send a log file via http to a server if a JAWS app fails. To test this I have setup a servlet that receives and processes the request. My Client code is as from the Apache HttpClient 4.2 examples { HttpClient httpclient = new DefaultHttpClient(); try { HttpPost httppost = new HttpPost("http://localhost:8080/testServer/testserv/a"); FileBody bin = new FileBody(new File("XXXs")); StringBody comment = new StringBody("A binary file of some kind"); MultipartEntity

Here is my JSP form: <form name="add_product_form" id="add_product_form" enctype="multipart/form-data" method="post" action="Product.Add"> <div id="form-body"> <div id="lebel"> <font color="red">*</font>Product Name: </div> <div id="field"> <input type="text" name="product_name" id="product_name" value=""> </div> <div id="lebel"> <font color="red">*</font>SKU

问题 I am having a webapplication built using Servlet and JSP. I have built a file upload functionality using apache commons library. I would like to restrict the user from uploading a huge file - hence have set the limit as 20 MB. I am getting the size using Fileitem.getSize() method which I guess is reading the entire file to determine the size. If a user tries to upload a file of few GBs in size , then wouldn't it add a lot of overhead on the application server? Is there any better alternative

问题 I am trying to persist a uploaded file to database using JPA. The most "natural" way (to me) is to define domain object as: @Entity class UploadFile { ... public CommonsMultipartFile getFileData() { return fileData; } } But this won't work since there is not such a database mapping type. Searching online, I found that people seems to adapt one of the two methods: Define the field as java.sql.blob; Define the field as byte[] In the @Controller class, the incoming HttpServletRequest gets cast

问题 When a file say 100 MB size is uploaded from browser will Spring hold whole data in memory or stores in the disk temporarily. After going through Spring doc I know how to set a temp dir but I want to know what will happen if I don't mention that. Am having following declaration : <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/> Bean : public class FileHolder { private MultipartFile file; public void setFile(MultipartFile file) { this

问题 I am using org.apache.commons.fileUpload.FileItem and other related classes for uploading files from local machine to server (Although for the current testing both the machines are same). I am having .jsp file as UI and servlet to handle the upload. Now when the request reaches statement List items = upload.parseRequest(request); it returns empty list.
