Simple Ftp Server For Uploading And Downloading File
Jan 25, 2014
I want to create a simple ftp server which can upload and download a single file. i found code from google search but its showing error : connection refused . here is my server code n client code.
I would like to know what is the best way to upload & download files using Servlets/Jsp's . In some websites I have seen example using third party API(by oreilly). Is it better to follow any third party or can we do it just by using I/O streams. What are the steps of uploading files. And where do we need to store files once the user uploads ,Database or server??
I am developing an inhouse project in my organization. I unable to implement the pdf uploading, downloading, report generation logic as i am totally new to this implementation.
@ManagedBean @SessionScoped public class HelloBean { public void downloadFile() { File file = new File("C:datacontacts.doc"); HttpServletResponse response = (HttpServletResponse)
I'm a independent IT contractor. On 2 systems this week I've experienced an issue when attempting to download JAVA the file is of an unknown type in IE. See attached. Alternative browsers on the same machine function properly.
I have a template file which I'm tring to upload into a database using setBlob or setBinaryStream but I'm getting the following error:
java.lang.AbstractMethodError: setBlob at weblogic.jdbc.wrapper.PreparedStatement.setBlob(PreparedStatement.java:1005) at com.capitalone.citrix.ssp.dao.KatetDaoImpl.uploadReport(KatetDaoImpl.java:1697) at com.capitalone.citrix.ssp.services.FileOpsImpl.generateDownload(FileOpsImpl.java:648) at com.capitalone.citrix.ssp.controller.JSONController.display(JSONController.java:61) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
[Code] .....
I'm using :
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production Weblogic Server Versions: 10.3.0.0 with Java 1.6.0_05
The driver class name for the weblogic datasource: weblogic.jdbcx.oracle.OracleDataSource
Initially, I tried:
sqlQuery = new StringBuffer(); ps = null; sqlQuery.append("insert into KATET_REPORTS (FILE_DATA)");
[Code] ....
This failed, so I changed ps.setBlob(1,is) to ps.setBinaryStream(1,is). This failed as well with teh same error, just for setBinaryStream instead of setBlob.
Is there a known inconsistency between that driver and this Weblogic version? Is there something else going on? If I haven't given enough data to debug the issue here, what other data should I gather?
I've been trying to create a server/client chat program, but I keep running into areas where I'm not really sure how to work it. I've run into a wall where my client just sits and spins instead of working. URL.... I can work out the dynamic parts later, I just want to understand the meat and potatoes of reading from sockets and writing to sockets (and how to do both at the same time).
I worked on this simple client server chat app and it worked now for my project i needed to work on client server audio streaming broadcast but i dont really know much bout audio api and methods on java...
I am downloading around 50 PDF files programmatically using Java program(like a servlet service) one after another in for loop. I am observing that , i'm getting timeout error after few files are downloaded itself. How to solve this problem and download more files programmatically using java? The files are in my server at different location.
i have a service to save some form fields from the client and i need to add uploading image to that service using json. the service consumes json and produces json.
My requirement is - I need to browse the folder and select multiples and upload all the selected files at once. note that here i need to use single browse button ONLY.
I am learning how to program in JAVA servlet+MySQL. Decided to make a simple program where it shows who is celebrating birthday today by retrieving data from database. At the moment I managed to get it working by loading a form.html and pressing the button in it which gets to the result.jsp and shows results there.
My plan was to get a list of people who are celebrating there birthdays initially when the website is loaded/being loaded, I mean when you enter URL into your web browser and you get it instantly in browser. Is there a way to do it the way I want (JAVA+servlet+MySQL) instead of pressing a button/link?
I am creating a server that stores application updates. When the client connects the server send the update. The server is sending the file but the file is not complete, i.e, if the file is 317kb,its send 117kb. Below is the code I am using :
import java.io.BufferedInputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.OutputStream; import java.net.ServerSocket; import java.net.Socket; public class TestFileServer {
I have a requirement to get the details of the files present in a directory on a server. I need to get the file names and timestamp. I have the below code to get the file names:
Connection conn = new OracleDriver().defaultConnection(); ArrayDescriptor arraydesc = ArrayDescriptor.createDescriptor ("DIRLIST_T", conn); File myDir = new File (dir); String[] filesList = myDir.list(); ARRAY dirArray = new ARRAY(arraydesc, conn, filesList); return dirArray;
But am not able to get the timestamp. How can I get the timestamp as well.
I am developing a web application in java(JSF 2.0 - Prime Faces). I need to do below operation. My appllication is running on WLS server. WLS is deployed on a server(say Machine-X). In my application i have a requirement , where i have to copy file from Machine-X to another Machine-Y. The Machine-Y is access restricted.
When i tried to copy the file from my app, getting no access exception. I have full control over Machine-Y. We cannot use SFTP as SFTP cannot be installed on target machine(Machine-Y). Robocopy is failing for some use cases. Is there any other way we can copy/write file from one server to other by providing userid/password in java

I am trying to create a new text file in FTP Server using FTPClient but im not able to do. By using storeFile method i can only upload file that is already exists in my local system. But my requirement is to create file directly into FTP Server.
I'm trying to do a program that send a single file from a client to a default directory of a Server. The program use the datagramSocket and datagramPacket for the transfer via UDP. The client sent the packet of the file correctly and the server start the receiving but every time the Server class crashes after it's receiving 4/5 packet (exactly 8192 byte)
Then i put the code of the 2 class and the 2 output.
OUTPUT CLIENT:
PROGRAM TRANSFER PACKAGES name of file is : Doc1.pdf his dimension: 11408 byte
PROGRAM TRANSFER PACKAGES START NEW CONNECTION Directory: C:prova Server waiting in port: 9876 Waiting Client... Name of file is : Doc1.pdf Dimension : 11408
[Code] ....
In this point the program go in loop and didn't anything. I don't understand how can i resolve it...
I am developing a web application using JSF-2.0 on weblogic 10.3.6. I am using Facelets as VDL. I have 5 different machine. They are different according to their OS and their geographical location. On my first xhtml page server (machine) is decided. Then on next page file upload and rest of processing takes place. My restriction is that SSO configuration can be done on only one machine.
So I am restricted to using xhtml files from only my primary server where SSO configuration is done. But I have to connect to servlets or managed-bean of different machine as requests are machine specific and file needs to be uploaded to those machines for processing. So I cannot use redirectUrl as I need to be only on one machine. Is it possible that xhtml on one server can talk to managed-bean on other server(different machine)?.
