File upload to web server
I need a little help with the file upload process in flex..
I am trying to upload a file.. i had it where i would get a cgi-script url passing as the following
filename="filename"&filedata="data of the file"
then my cgi script "written in C" would read from standard in.. and write the info to a file...
now i get the following..
------------KM7Ef1gL6Ij5cH2ae0ei4Ij5GI3Ef1
Content-Disposition: form-data; name="Filename"
Botanical Garden 239.JPG
------------KM7Ef1gL6Ij5cH2ae0ei4Ij5GI3Ef1
Content-Disposition: form-data; name="Filedata"; filename="Botanical Garden 239.JPG"
Content-Type: application/octet-stream
in the file i am trying to write.... Can anyone help me fix this problem? I am clueless at this point on what to do..
sample code below is what i got from trying to work this...
Thanks in advanced for anyones help..
<code>
const FILE_UPLOAD_URL:String = "http://172.16.1.6:1111/cgi-bin/login.cgi";
private function init():void {fileRef =
new FileReference();fileRef.addEventListener(Event.SELECT, fileRef_select);
fileRef.addEventListener(ProgressEvent.PROGRESS, fileRef_progress);
fileRef.addEventListener(Event.COMPLETE, fileRef_complete);
private function browseAndUpload():void {fileRef.browse();
message.text =
private function fileRef_select(evt:Event):void {
try {message.text =
"size (bytes): " + numberFormatter.format(fileRef.size);fileRef.upload(
new URLRequest(FILE_UPLOAD_URL) );
trace("going to print file data in a sec... ready?");
trace(fileRef.data);
trace(fileRef.name );}
catch (err:Error) {message.text =
"ERROR: zero-byte file";}
private function fileRef_progress(evt:ProgressEvent):void {progressBar.visible =
true;}
private function fileRef_complete(evt:Event):void {message.text +=
" (complete)";progressBar.visible =
false;}
</code>
Here are some code....

MultipartRequest multi = new MultipartRequest(request, "C:/multipart/", 10*1024*1024); // 10MB
Enumeration params = multi.getParameterNames();
while (params.hasMoreElements()) {
String name = (String)params.nextElement();
String value = multi.getParameter(name);
out.println(name + " = " + value);
out.println();
Enumeration e = multi.getFileNames();
while(e.hasMoreElements()){
String fname = (String)e.nextElement();
out.println("<h1>"+fname+"</h1>");
File fl = multi.getFile(fname);
FileReader fr = new FileReader(fl);
BufferedReader buf = new BufferedReader(fr);
while(buf.ready()){
out.println(buf.readLine());
out.println();
buf.close();
fl.delete();

File upload through web server to weblogic
WAS: Weblogic 10.3
Web Server: Sun One Web Server 6.1
JDK: 1.4
I've deployed a web application(*.war) to weblogic server, and try to upload a file through sun one web server(webserver) to the weblogic. The 'webserver' does nothing but bypass the request to weblogic. When I do upload a file to weblogic server directly without though webserver it's ok. I mean the uploaded file would be written to a specfied saving directory on server as soon as the upload process gets start. But with going through webserver, it does not happen immediately. After a long time passed the uploaded file begins to be written to the saving directory. The 'webserver' seems to buffer the amount as much as the file size, and then send them to weblogic. To sovle this problem I tried to change the webserver configuration(magnus.conf) as like,
ChunkedRequestBufferSize 0, UseOutputStreamSize
But doesn't work.
Is there somthing of I'm missing? Get me out of this struggling.Thanks for your comments.
What I'm doing is that first I made a simple upload jsp file using 'com.oreilly.servlet.MultipartRequest', and then try to upload with a html page over IE browser.
That is,
IE browser ( Local PC ) ---> Sun One Web Server ( Remote machine ) ---> Weblogic ( Local PC ).
And I also peeked into the transferred data between webserver and weblogic. What I've found is that all data in the upload file would be buffered into webserver and then flushed out to weblogic at one time. I want to upload the file to weblogic server without buffering in webserver. Rather than a bug of webserver, I thinik I missed some configuration stuff of webserver, or weblogic.
Local PC: Windows XP
IE: 6.0
Web Server: Sun One Web Server 6.1 SP9
Weblogic: 10.3.0.0
upload filesize: 4MB -
Uploading a file to the web server
How can i upload a file to the web server using JSP.
hello sir,
Could U even tell me performance which one is better.
U have mentioned that Multipartrequest is Complex for Beginers,
but as far as performance is concerned which is better.
If Taglib is used is it error Free , as I do not know much abt taglib.
have just read a little abt it , have never created my own Custome Tag.
Could U just Guide me which is the best site where I could get know a little abt Taglib.An easy tutorial where I could read and start working on My application.
I have been given a Deadline. So Please help me man.
If U have the source Code for Uploading of a File Please Cut Paste it.
I have to finish the project on time .
Please
With Regards

Problem uploading Muse-exported files on my Web server
I'm using the FTP client Transmit for years and I'm very pleased with it.
I use also Muse from the first preview and I always use the "Export to HTML" feature, and place the files on my remotely-hosted Web servers (NetSol).
When I upload all kind of files (HTML, CSS, .ZIP, videos,…), everything works fine.
Since yesterday, when I upload files generated by Muse, Transmit stalls and is unable to save the file on the Web server. I receive all kind of transfer errors.
Something must have happened recently.
I use the latest Muse CC2014 version and the latest Transmit version.
I called NetSol support and they said they change nothing on their Web servers recently. They point out that all my non-Muse files upload correctly.
The big problem is that I can't update my websites anymore.
How to share here the exported Muse folder?
Thank you.Switched to FileZilla
Here's the current log and it is failing all the time.
NetSol told me they have restarted the server and checked for authorisations, and they say it should work as it works for other files.

I want to cache all files in my web server for JRE auto installation
Hi,
I have written an application for my customer. When they access my web server, they will auto-install jre 6.12 and then load my application using jnlp. All that is done, but i want to improve in the following ways:
1. I want to have more quiet installation of java. It should only show progress bar or just run in background. In the jre installation file (cab file), there is a file jinstall-6u12.inf, the last line is "run=%EXTRACT_DIR%\jinstall.exe /installurl=http://localhost/1.6.0_12-b04.xml /installmethod=plugin". What should I add to this line to make the installation more quiet?
2. When my client install jre, i want them to fetch all necessary files from my web server, so when java web site is down, i can still provide files they need to install java. I am aiming jre 6.12 only.
Thank you in advance.

The "Quick Erase" option will only take a few minutes, but it is not a secure Erase.
The "Zero Out" option will replace everything on the disk with zeros, and will likely take 4-6 hours for the process to complete, depending on the size of the drive.
The erase procedure will only affect the disk. It will not affect any of the network settings, passwords, etc that you have stored on the Time Capsule. -
File Based Multithreaded Web Server Question
Hi friends,
I have the code of a simple File Based Multithreaded Web Server. I have been asked to add proper http/1.1 Keep-Alive behavior to it. As far as I understand it means to use the same socket for the request coming from the same client without opening a new socket for every request by it. I am unable to implement it. Any help would be greatly appreciated. The entire code is as below:

Deploying war files on iplanet web server 6.0
Hello All,
I tried to deploy an war file on iplanet web server 6.0 using both command line wdeploy and iplanet webserver browser based admin tool. Both the times it did say successfully deployed. I checked the WEB-INF files and it does contain all class files..But the problem is when I try to post a form to one of the class files the error log says as if it cannot find the class file.(I tried the sample app HelloWorld supplied by vendor)
=========
05/Mar/2002:13:19:14] config (13777): for host xx.xx.xx.xx trying to POST /samples/helloworld/GreeterServlet, handle-processed reports: The request method is not applicable to this requested resource.
=================
any help in this regards is appreciated
Thanks
sudhirHello,
I got few steps to deploy the WAR file, if you followed the same steps and got the error then ignore this else try with this steps.
a) Set your environment variable IWS_SERVER_HOME to your server_root directory.
b) Add the server_root/bin/https/httpsadmin/bin directory to your classpath.
c) Configure your virtual server for web applications.
From the Server Manager page, select the VirtualServerClass tab, select a Class, and click the Manage button.
Select a Virtual Server and go to the Java Web Apps Settings page for that virtual server. Make sure that the virtual server has Web Apps State turned On, and web-apps.xml is the name of Web Apps File.
To extract the sample WAR file HelloWorld.war in server_root/plugins/servlets/examples/web-apps/HelloWorld, use the wdeploy command as follows:
wdeploy deploy -u /hello -i server.iplanet.com -v testvs -d
/iws60/https-server.mydomain.com/testvs/web-apps/hello
/iws60/plugins/servlets/examples/web-apps/HelloWorld/HelloWorld.war
The syntax for the command is as follows:
wdeploy deploy -u uri_path -i instance -v vs_id [-d directory] war_file
uri_path Specify the URI prefix (a path to access the web application from the browser).
instance Specify the server instance name. (Note: Do not include "https" in the front.)
vs_id Specify the Virtual Server name as it appears on the Manage Virtual Servers page.
directory Specify a directory to extract WAR files. If this directory doesn't exist already, it will be created for you now.
war_file Specify the name of the WAR file.
If the WAR file is extracted successfully, the message "web application deploy successful" appears at the command line.
For verification, go to the /iws60/https-server.iplanet.com/testvs/web-apps/hello directory. It should have the following contents:
colors
index.jsp
META-INF
WEB-INF/
web.xml
/classes/
HelloWorldServlet.class
HelloWorldServlet.java
SnoopServlet.class
SnoopServlet.java
In the server_instance/config directory, the web-apps.xml file should have the following entry:
<vs>
<web-app uri="/hello"
dir="/iws60/https-server.iplanet.com/testvs/web-apps/hello"/>
</vs>
Restart the server instance from the command line or go to the admin GUI and apply configuration changes to the server instance.
Now when you access the webserver instance in your browser, the Error log of that server instance will record successful initialization of the web application environment(web-apps.xml) for the virtual server(vs name). You can access the web application from a browser as follows:
http://server.Mydomain.com:80/hello/index.jsp
or:
http://server.Mydomain.com/hello/
The syntax is as follows:
http://vs_urlhost[:vs_port]/uri_path/[index_page]
Thanks

Deploying an ear file in Sun Web Server
I have an ear file that we use to deploy to weblogic. Is it possible to deploy an ear file to Sun WEb Server 6.0? Instead of deploying the war files one-by-one?
If yes, what are the steps?
Thanks.
BethNo, Sun ONE Web Server does not support ear files; ear files are typically the domain of J2EE application servers.

Captivate Files Loaded on Web Server
I have loaded a captivate file (along with all its dependent files) onto a web server in order to link it to our Plateau LMS. I had no problem with the link, but a narration that is supposed to start later in the file begins when the main Captivate page is opened. I am not the creator of the Captivate file and have never worked with the program. Is there something that needs to be done to the file to keep it from doing this?
Are you using Aggregator? Or is is a very long project? I've noticed Aggregator projects often want to jump into the audio while the presentation is still loading. The easiest fix for that is via Edit --> Preferences. Select Start and End in the Project group, uncheck Auto Play, and, as a touch of class, add a graphic to be displayed until the user presses the play button (which will be in the middle of the presentation when it loads).

Hello,
How could I start writing an applet for viewing files on my web server? I looked around the forum and on the net but couldn't find anything very helpful. Any resources or links are also much welcome.
Thanks,
LDThanks for your reply Andy,
All I want to do now is have something user friendly so that they could browse a tree folder and download some files on my web server. I don't really know if I should stick with Java or opt out and go try using JavaScript or other scripts - what's your view on this?
I wrote some code in Java that creates a folder tree, starting from the folder where the applet is placed. Then I would have a table showing all the files etc...In my IDE it works fine but on the server it either doesn't show anything or complains about security issues (I tried different methods).
(My web server is just a common commercial web server. When there's no index.html on a particular folder on the server and I locate it in my web browser, it does show a listing of all that is in there.)
Here's my code:

JSP : latest JSTL, File Upload from web form Client to Server Question!
I understand that within a JSP, It is possible to read a file from the Client by opening a Stream somehow.
How do I code, within jsp/servlet (non tag) java code inside <% %>
blocks, WITHOUT openening a new connection to the URL, an InputStream from a client web browser form, from a file upload coded using
<input type="file" name="file1"/> ?
I have previously achieved this quite simply with a FileInputStream
with the previous version of JSTL.
How may I do this with the latest version of JSTL, with this index.jsp?
-with a simple text file.
-with a Binary file (with DataInputStream)?

<input name="file1" type="file"/>
<input name="submit1" type="submit" value="Submit" action="index.jsp"/>
</form>
<!-- ***********************************************************************************-->
and run this in an index.jsp, use browse to select my text file, and click SUBMIT.
I can use:
InputStreamReader reader = new InputStreamReader(new DataInputStream(request.getInputStream()))
BufferedReader bufferedReader = new BufferedReader(reader);
bufferedReader.readLine();...
However, these is some HTML/POST related content around what multiple readLine();
calls return.
Is there an easy way, like using "${param.file1}",
aside from [http://commons.apache.org/fileupload/|http://commons.apache.org/fileupload/],
maybe using servlet style code, to get the File contents from a remote Client,
to the remote Server servlet engine, AVOIDING ANY SUPERFLUOUS CONTENT,
using version 1.12 of the JSTL, JSP 2.0,Tomcat 6?
Just politely, yes, no, and how?

How to save uploaded image file to Apache Web Server from Tomcat
Hi guys,
Perhaps this is not an appropriate topic to ask under this forum but I really don't know where should I post my question. Hope you understand.
Ok, I need to know if my web application is running in Tomcat5 and user uploading some image file where I need to save these image files to the other server, which is running Apache Web Server. Should I ftp to there or other better method ?
Anyone got a better idea on doing this kind of process pls advice. Many Thanks !
regards,
Markif your Apache server is running in the same computer and if your servlet have write access to the folder in apache under which you want to save the file you can just write the file there but you will have to address concurrency issues.
Otherwise you will have to do ftp but since apache does not have abuilt in frp server you will need a seperate FTP server for this -
Issue with permissions to upload files into Apache web server to OS 10.8.2
Hello everyone;
I setted up Apache web server and mysql to OS 10.8.2 Mountain Lion. It's working fine except for the permissions. I can't upload files into the web site directory. Doesn't recognize, e.g., the PHP function "move_uploaded".
One problem for my is that I can't modify the permissions by "Terminal" app since it telling me that the "Process completed" and I can't write any script.
Any suggestion will be welcome.
Thanks in advance.My only question now would be how to speed up Safari's 6.0.1 performance in 10.8.2 or do I just accept that it's a little slower than it was, which is fine. Are other folks having this issue?
I was primarily passing along info about my particular download speed and for the Web Confidential 3.8 people: make a backup of your passwords b4 installing 10.8.2 or be prepared to upgrade.
Maybe you are looking for
