}This program works fine for downloading files, over both http and https from my home. When I run this on my desktop in the office it can download files over http, but cannot download https files.
When I try to download files over https, I get the foll. exception:
java.net.UnknownHostException: www.site.com
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:153)
at java.net.Socket.connect(Socket.java:452)
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.connect(DashoA12275)

at com.sun.net.ssl.internal.ssl.SSLSocketFactoryImpl.createSocket(DashoA12275)
at sun.net.www.protocol.https.HttpsClient.doConnect(DashoA12275)
There are 2 differences here, one being that my office desktop sits behind a firewall and there is a proxy in between.
In the office I run the program as :
java -Dhttp.proxyHost -Dhttp.proxyPort TestServlet URL [filename]
eg.:
java -Dhttp.proxyHost=235.67.138.84 -Dhttp.proxyPort=8080 TestServlet https://site.com/portal/Downloads/file.csv file.csv
This url requires authentication, the userid and pwd are hardcoded in the code.
Now, my problem is I cannot understand why this error would come. Is it because of the firewall or because of the proxy ?
Why is it that I can download over http successfully from my office desktop? If the problem is with the firewall or proxy, then even http protocol urls should give the same problem.
Please help.

If you are using HTTPS you should be setting
https.proxyHost
https.proxyPortnot the http.* ones.

Header variable: Content Disposition for downloading file over HTTP?

Hi All,
I have a general content server question...Is there anyway to pass a parameter or set a setting on the content server to send the file with the header variable content-disposition set so that when a user selects a file within a browser, it doesn't open in place but asks the user whether they want to open or save the document?
Note - I'm actually using this with ArchiveLink and displaying the link in the Portal but this forum seems the closest I can get to asking this question.
Regards,
Matt

Thanks Athol.
Although there's quite a bit of configuration options there for displaying files, there doesn't appear to be anything that let's you manipulate the HTTP header variables to set content-disposition.
Any other ideas?
Cheers,
Matt
ps. If you want to artificially see the behaviour I'm after, within IIS, you can predefine this header variable for the contentserver.dll but this makes every HTTP request act like a file that wants to be downloaded, and it calls every file contentserver.<suffix>. From a user perspective, there's nothing worse than a document opening in place in your window (losing the underlying application), or within another IE window, hence why I'd like it to act like a file download.

Downloading Text file over http

Hi,
I am trying to display some plain text files over http to the client using a web browser. Everything works fine till the time the file size is small, but for the files of over 1MB the frontend just dies. Probably the display happens only after the complete transfer of the file.
Does any one have the solution by which the text files can also be downloaded similar to the html files i.e. incrementaly. I have the code of transferring the html file over http as it happens in the explorer. But the same does not seem to work on the plain text files.
Please help
Sachin

I do not have any Remote server written for this. What i am doing is, the directory in which the files are stored is exposed as a virtual directory through a web server(Apache) and then from client i am just placing a http request to open this file.
So what i can do under this situations to handle the large files.

How to set iPad Mini to download files over 50MB?

I am downloading GarageBand to the iPad Mini and it says I need to connect using Wi-Fi to download files over 50MB, the question is why do I need to connect to a Wi-Fi Station? I have an unlimited LTE connection, what am I paying it for if I need to connect to a Wi-Fi to download files?

You can try using a MiFi.

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout).

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout). It is as if the server has decided that the client has timed out during the file upload. The default setting is 30 seconds for AcceptTimeout in the magnus.conf file. This should be ample to get the file across, even increasing this to 2 minutes just produces the same error after 2 minutes. Any help appreciated. Apologies if this is not the correct forum for this, I couldn't see one for iPlanet and Web, many thanks, Kieran.

Hi,
You didnt mention which version of IWS. follow these steps.
(1)Goto Web Server Administration Server, select the server you want to manage.
(2)Select Preference >> Perfomance Tuning.
(3)set HTTP Persistent Connection Timeout to your choice (eg 180 sec for three minutes)
(4) Apply changes and restart the server.
*Setting the timeout to a lower value, however, may prevent the transfer of large files as timeout does not refer to the time that the connection has been idle. For example, if you are using a 2400 baud modem, and the request timeout is set to 180 seconds, then the maximum file size that can be transferred before the connection is closed is 432000 bits (2400 multiplied by 180)

Flat file over HTTP or SOAP

Hey Guys,
I need to post a Flat file over HTTP (or SOAP), is this possible without developing my own Adapter module?
I just need to get a Flat file from a FTP server and post to another server via HTTP,since there is no message mapping involved, i developed the scenario without any Integration Repository objects, it is just a pass-through scenario.
Now i am stuck on the receiver side since i am unable to post Flat file over HTTP.
Secondly i have Login URL, Logout URL and upload URL from the receiver system, i don't see any place in receiver HTTP adapter to put all these 3 URL's, can i use SOAP adapter to put all these URL anywhere?
Any help would be appreciated.
Thanks
Saif

Retreiving files over http or ftp.

I was wondering what program I should use to retreive files over http or ftp. Previously I had used wget per my hosting provider's recommendation. It worked when I was ssh logged in to his server (via Mac Terminal). However, when I try using wget on my local Mac it says "command not found".

Thanks. So if I specify a file name (-o /path/to/file), does the incoming file get renamed to that (and put in that location) or does this specify the directory (-o /path/to/directory) that the incoming file will go to? I wasn't quite clear on that.
Also, I keep hearing about stdout. What is it exactly? I assumed it was just the Terminal window itself, the alternative being things like | more or | nano or something like that... Or am I totally up the wrong tree?

Play an audio file over HTTP

Hello everybody,
I'm trying to play an audio file over HTTP protocol. The code is the following:
public class HTTPClientJMF {
     static String url = "http://localhost/audio/Reklam1.wav";
     static String urlFile = "file:///C://tmp/audio/Reklam1.wav";
      * @param args
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          try {
               DataSource dataS = new URLDataSource(new URL(url));
               dataS.connect();
               Player player = Manager.createPlayer(dataS);
               player.start();
          } catch (MalformedURLException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          } catch (IOException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          } catch (NoPlayerException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
}Now, if I'm trying to play the file from the local disk (+urlFile+ - using file protocol), everything goes well, but if I'm trying to play the same file from the network (using http protocol) I get the following exception:
javax.media.NoPlayerException: Cannot find a Player for: javax.media.protocol.URLDataSource@fa9cf
Can somebody tell me what I'm doing wrong?
Thank you!

Ah',..okay. I constructed the DataSource like follows:
Buffer mediaBuffer = new Buffer();;
          String mediaURL = "http://ares.inescn.pt/video/Reklam1.wav";
          URL url;
          try {
               url = new URL(mediaURL );
               InputStream in = url.openStream();
               BufferedInputStream bufIn = new BufferedInputStream(in);
               for (;;) {
                    int data = bufIn.read();
                    // Check for EOF
                    if (data == -1)
                         break;
                    else
                         mediaBuffer.setData(data);
               System.out.println(mediaBuffer.getLength());
               if (mediaBuffer.getLength() != 0) {
                    DataSource ds = new DataSource();
                    HttpStream[] httpStream = ds.getStreams();
                    System.out.println(httpStream.length);
                    httpStream[0].read(mediaBuffer);
                    ds.connect();
                    ds.start();
                    Player player = Manager.createPlayer(ds);
                    player.start();But I still cannot play an audio file (wav format) over the HTTP. Application starts but nothing happened.
I make the modification like you suggested. (into the DataSource, more exactly for method getStreams()).
I renamed as well the HttpDatasource into HttpStream.
Did you actually tried the code? I've been reading the instruction how to test the code but I did not be able to run the example.

I can't download files over 200 mb. What's wrong?

Every time I try to download a file over 200mb it looks like it's downloading but when it has loaded 100% it doesn't finish so it doesn't get saved. It's not a space problem and it has always worked before. (It's not the browser either, I have tried it in firefox too).
This is how it looks..
If anybody knows what could be wrong and how to fix it, please help. Much appreciated.

A .rar extension requires a utility to open.
RAR Expander for Mac - Free software downloads and software reviews - CNET Download.com
And check Safari > Preferences - General
Make sure: Open "safe" files after downloading is selected.
If it still won't open, go to ~/Library/Safari
Move the Downloads.plist file from the Safari folder to the Trash.
Quit then relaunch Safari ... try again.

Downloading file via HTTP

Hi,
is it possible or exist some adapter or service, which can
process(or download) file placed on HTTP server?
Thanks
Martin

Chtira,
I've done it in JDeveloper with HttpServlet class and not in BPEL. I've overridden the doGet and doPost methods.
doGet looks something like this:
public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
    throws ServletException, IOException
    response.setContentType(CONTENT_TYPE);
    PrintWriter out = response.getWriter();
    out.println("<html>");
    out.println("<head><title>Communication</title></head>");
    out.println("<body>");
    out.println("<p>GET method is not supported. Please use POST method for XML messages.</p>");
    out.println("</body></html>");
    out.close();
}doPost method is a bit more complicated. Basically I'll call my BPEL processes with the XML messages I receive but I'm still struggling with XML validation against a schema in this servlet class.
When you have the class you have to put something like
<servlet>
    <servlet-name>HttpServletPost</servlet-name>
    <servlet-class><your package>.HttpServletClass</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
     <servlet-name>HttpServletPost</servlet-name>
     <url-pattern>/Communication/*</url-pattern>
</servlet-mapping> in your web.xml file.
Hope this helps you somehow.

Post file over Http

Hi All,
I am working on EDI scenario in which EDI partner has given one HTTP site address with user name and password. I will have to put EDI file at that site using http/soap adaptors at receiver end.
One thing I know for sure that I can not use File channel at reveiver side as there is no FTP available. Now Can anybody please let me know how to generate file using http connection?
I have absolutely no idea how to use http and soap adaptors so if any links to the blogs will also be helpful.
Thanks in advance,
Atul

Hi Aamir,
Thanks for your reply.
I just want to generate a file at given location. I am confused what is the difference in data sent as a payload or as attachment?
As you said in case of attachement we need to use some modules(Looks bit difficult ) I would perhaps like to generate file by using Payload .
Can you suggest some blog for the same?
Thanks and Regards,
Atul

Wiki CSS files over HTTPS use only RC4

I finally found the answer to my problem of why the wiki CSS files wouldn't load.
It turns out that the wiki forces an HTTPS connection and it retrieves the CSS files from https://d11xdyzr0div58.cloudfront.net. The encryption used for those CSS files uses 128-bit RC4 with MD5. In Firefox, the about:config parameter name is
security.ssl3.rsa_rc4_128_md5
I had turned off all RC4-based encryption for SSL3 in about:config because RC4 is old and not appropriate for secure use in the modern day. Since SSL works by the server offering to the client all of the encryption algorithms it's willing to use, and then the client selects the ones it likes, my assumption was that if the encryption parameters for a connection include RC4 Firefox would just not ever pick one of the RC4 options. However, I had no idea that there would be a website that ONLY offered RC4. My guess is that this is the case for the wiki's CSS file server, because only by turning on the about:config parameter mentioned above can I get the CSS files to load.
Is there a way to address this issue? Preferably, either the CSS file server needs to support alternative algorithms (it looks like a cloud host, is that under our control at all?), or the wiki needs a way to be viewed in non-HTTPS mode. I don't care about the security of the wiki CSS files, I care about having RC4 turned on in Firefox -- I shouldn't have to enable it.
I considered filing a feature request, but I wanted feedback first.

A couple of years ago, I wrote an extension for Firefox called CipherFox (see my sig below). One of its features is disabling RC4 in about:config. I've had RC4 disabled all this time, and the Arch Wiki is the first time I've ran into trouble with it being disabled.
I too don't care much about the CSS files being encrypted. Here's what I did a couple of months ago as a crappy, hacked-up workaround:
(1) A Greasemonkey script to change link and script href's to point to http instead of https:
// ==UserScript==
// @name Archwiki Cloudfront SSL
// @description Removes SSL from Cloudfront href's
// @version 1.0.0
// @author MkFly
// @include http://wiki.archlinux.org/*
// @include https://wiki.archlinux.org/*
// ==/UserScript==
var head = document.getElementsByTagName('head')[0];
var link = head.getElementsByTagName('link');
var script = head.getElementsByTagName('script');
var cloudfront = "d11xdyzr0div58.cloudfront.net";
for (var i in link) {
link[i].href = link[i].href.replace("https://" + cloudfront, "http://" + cloudfront);
for (var i in script) {
script[i].src = script[i].src.replace("https://" + cloudfront, "http://" + cloudfront);
(2) With that installed, loading the Wiki pages was still delayed while it tried to connect via SSL and waited to time out. I worked around that by blocking them with Adblock Plus:
|https://d11xdyzr0div58.cloudfront.net/*
I know this is a hacky way to do it, but it works for now. Hopefully Cloudfront will let us use something better than RC4 in the future.

Downloading files from http

I want to download the Boot Camp program from terminal.... i was wondering what commands are involved in doing that... i already have the Boot Camp Address... just need the commands... i remember doing a tutorial on CVS that had me download and extract something.. but i don't remember how i did that.... so... any help would be greatly appreciated.

There are a number of ways of downloading via the command line. One of the commnest is via curl:
<pre class=command>curl -o /path/to/save/file http://server.net/path/to/remote</pre>
Where /path/to/save/file is where you want to save the file when it's downloaded.

Stream rather than download videos over HTTP

I have a home-built NAS server running a custom Web server.
When I click an MP3 file from my NAS, it streams in Safari. It does not download, which is fine, and actually the behavior I want. (If I need to download, I'll right-click and choose Download.)
But when I play a video file, it simply starts downloading it no matter what I do.
The only solution I have for streaming video off my NAS is to copy the link to the video with a right-click, open QT Player, bring up Open Location and paste the URL. QT Player streams the video just fine.
I'm guessing this has either to do with a MIME type issue or a headers issue, and not a Safari configuration problem. I can't find any settings that would allow me to change this behavior in the Safari UI.
What I want to happen is for the video file to play in the browser window similar to how MP3 files do. I have seen this happen properly on older Safari builds accessing videos from public web sites, so I know it's possible - unless Apple removed this ability for some deliberate reason recently.
Since I have control over the Webserver, I could change the MIME type it sends for m4v files. I just don't know what I should change it to, or if it's even possible to modify Safari settings in such a way to make streaming in-browser the default behavior.
Is this possible to do?
Thanks!
F

Yes, turned out my web server was giving the generic "application/octet-stream" mimetype. I told it to issue "video/mp4" and that seems to have worked. video/x-m4v also worked so maybe it doesn't matter which.
Solved!
