HTTP Download

How can you download a HTTP file into a directory on your computer? The file type of the file is .mp4 so I can't read the data then save to my computer.

Can codebase work with a HTTP path, or are we doomed to "HTTP download of assemblies has been disabled for this appdomain"?

Hello All,
After my long research I still can't load dll via <codeBase> .
I used in IIS 7.5.
I have client/server application.
Client is asp.net pure application that call to wcf service.
Wcf Service have reference to SingleCalculation.dll. In wcf service web.config I define <runtime></runtime>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="SingleCalculation" publicKeyToken="82e196dda8eaccb5" />
<bindingRedirect oldVersion="2.0.0.0-3.0.0.0" newVersion="2.0.0.2" />
<codeBase version="2.0.0.2" href="http://192.168.126.100/SingleCalculation.dll" />
</dependentAssembly>
</assemblyBinding>
</runtime>
This is Error :
Could not load file or assembly 'SingleCalculation, Version=2.0.0.2, Culture=neutral, PublicKeyToken=82e196dda8eaccb5' or one of its dependencies. HTTP download of assemblies has been disabled for this appdomain. (Exception from HRESULT: 0x80131048)
Please help me understand what I need to do to load dll via HTTP.
I believe this is iis issue , because this dll I can load in next configuration:
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="SingleCalculation"
publicKeyToken="82e196dda8eaccb5" />
<bindingRedirect oldVersion="2.0.0.0-3.0.0.0"
newVersion="2.0.0.2" />C:\temp\TestFolder
<codeBase version="2.0.0.2" href="file:///c:/temp/TestFolder/SharedAssembly/SingleCalculation.dll"/>
</dependentAssembly>
</assemblyBinding>
Thanks,
Best Regards

Hi,
About the issue, I suggest that you post it in IIS forum.
this issue indicates that AppDomainSetup.DisallowCodeDownload has been set
on this domain. Setting its flag will prevent any http:// download of assemblies., please refer to the similar discussion:

MMAPI: abort media HTTP download

Another MMAPI-related question: I have created a simple media (audio/video) playback MIDlet that downloads media files via HTTP. I want to be able to cancel the playback process programmatically: This works fine once the media file is downloaded and is being played back, but it does not work before downloading is complete! The problem seems to be the following: Before calling
player = Manager.createPlayer(mediaURL);the player does not yet exist (and player.close() results in a NullPointerException). Once createPlayer is called, the MMAPI implementation will mercilessly block until the download is complete. I simply can't believe there's absolutely no way to abort the HTTP download!?! Has anyone ever tried this? What's the trick? Grateful for any help,
cheers & a happy new year,
rainer

There are a few things you can try, which may or may not work, depending on the implementation. If you use the stream input form of createPlayer, you can close the stream in another thread, which should cause an exception in createPlayer. Or you could implement a simple intermediate (filter) stream class that you can signal externally to stop reading. And for CLDC 1.1 devices, you can try interrupt(), which should cause an exception in the player setup thread. But if the implementation also blocks key input, there's not much you can do.

ACE 4710: Config Allows all traffic except large HTTP downloads

Hi Folks,
Got an ACE 4710 with a basic config that seems to work for all traffic except large downloads.
I've attached the current config
As I mentioned I can do normal HTTP to a standard destination like google or SSH through the ACE or ICMP
If i try to get a large file from the server side of ACE, then a trace shows that the first and subsequent 1460Byte packets dont go through ACE
I've thought of parse lengths, but i cannot see any that seem to affect the generic L4 maps that I am trying to use
Cheers
Alan

I've seen a similar fault. I suppose a lower MSS was sent in the TCP SYN handshake packets (1300 or 1380?) and the packets exceeding that value were dropped by the ACE. This is the default behavior which can be switched to a less strict mode by either
exceed-mss allow
or
no normalization
commands.
In our case, a linux web server was whose replies wouldn't keep to the MSS limit.

AUSST HTTP Download Errors?

Hey Guys,
Just a quick question, trying to determine if it is just me.
Does anyone recieve HTTP Errors in their AUSST log at the moment? Every time I run the tool I get a couple of entries like this:
******** HTTP Error*********
Failed to open remote file http://swupdl.adobe.com/updates/oobe/aam20/win/PhotoshopCameraRaw764bit-7.0/7.2.82/7.2.82. xml
and
******** HTTP Error*********
Failed to open remote file http://swupdl.adobe.com/updates/oobe/aam20/win/PhotoshopCameraRawForElements10-6.4-x64/6.7 .040/6.7.040.xml
etc. And I think because it can't download I constantly have the
"FeedChanged (mac)= 1
Need to download updates for Mac" (or Windows, depending)
When I manually navigate to those addresses I get a 404 error. So is there a way to redownload the XML files without having to redownload the ENTIRE section of downloads?
Or is this some permissions error? Apache user serves the content but AUSST is run as "serveradmin" user. But internal server has 777 permissions for those downloads.

I still haven't heard anything about this. And I still am receiving these errors. Not sure what is going on!

HTTP download stops without any reason.

Hi,
I wrote the following code to download different parts of the same URL in different threads. The object manager is a custom class which manages the various threads in each download.
public void run() {
          try {
               byte [] buffer = new byte[1024];
               URLConnection conn;
               if(proxyAddr != null)
                    conn = src.openConnection(new Proxy(Proxy.Type.HTTP, proxyAddr));
               else
                    conn = src.openConnection();
               conn.setRequestProperty("Range", "bytes=" + (start + completed) + "-" + end);
               int response = ((HttpURLConnection)conn).getResponseCode();
               if(response != 200 && response != 206)
                    manager.failConnection();
               BufferedInputStream bin = new BufferedInputStream(conn.getInputStream());
               byte [] data = new byte[1024];
               int readLen;
               manager.addConnected();
               if(start == 0) {
                    System.out.println("Jing: " + end);
                    conn.setReadTimeout(5000);
                    System.out.println(conn.getReadTimeout());
               int cnt = 0;
               while((readLen = bin.read(data)) != -1
                     && canContinue) {
                    synchronized(dest) {
                         dest.seek(start+completed);
                         dest.write(data, 0, readLen);
                    synchronized(this) {
                         completed += readLen;
                         if(start == 0) {
                              System.out.println("hi" + cnt++);
                              System.out.println(completed);
               if(start == 0)
                    System.out.println("Read: " + readLen + "\t" + start + "\t" + end);
               manager.addFinished();
               bin.close();
          } catch(IOException e) {
               manager.failConnection();
               e.printStackTrace();
     }For some URLs, the thread which downloads the first part of the file begins the download and runs along with other threads but at some unpredictable point waits to read data infinitely, in spite of the fact that I've set the timeout to 5 secs. But, the other threads which download remaining parts of the file finish their downloads successfully.

I've set the timeout before opening the InputStream.
The download still stops at random places. However, by catching the SocketTimeoutException, I'm able to re-establish the connection and download the remaining content.
Thanx for ur help

Testdrive image availability via HTTP download?

Stop flv http download

Hi
I have a video flv into videodispay and when the user click play and then stop button the flv continue to download in background, how can I stop the http progressive download ?
thanks

If you're using VideoDisplay as a video Object, you should not only stop the stream, but close it. (Simply by calling the close() function), That would determinate the stream.

HTTP download problem

I have an HTTPS application runing on an IPlanet Web server. The web server is working fine, but it doesn't allow me to download any file using HTTPS.
The browser shows:
"The file could not be written to the cache" or
"Internet Explorer cannot download <file> from <site>"
- SO: Solaris 8
- Web Server: Iplanet + Chili ASP
- Browser: Internet Explorer.
Thanks in advance.

There's really not enough information here to identify the problem.
What version of the server are you using? Can other browsers (Netscape, Mozilla, Opera, whatever) interract with it in SSL mode? Are there any errors logged by the server?

Http downloading a 500 meg file is ridiculous.

I've now wasted a week trying to download the 9i database files to test an installation on a linux cluster. I'm on a very solid AT&T T1, and have attempted countless times to download the files through IE5, IE6 and Mozilla with no success.
I've even given in and tried to use the suggested Go!Zilla and GetRight, neither of which is an acceptable solution for downloading software from Oracle. Go!Zilla not only installed spyware on my system, it, along with GetRight, is unable to download these files because they provide no facilities for creating a user session via the required OTN login.
One would assume that through experience Oracle would realize that the FTP protocol is far more robust and useable in the case of transferring large files. The overhead of someone downloading a 500 meg file via FTP is not far beyond that of someone downloading the file via http -- the only real difference lies in the end user's experience which, believe me, is pretty horrible right now.
I have to download 3 500 meg files for this experiment to ee if we should license Oracle 9i, and this has proven impossible to do via http. Apparently, I'm SOL.

Did you ever get this resolved? I'm having the same issue.

HTTP Download Accelerator in java

i need to write download accelerator which transfers files over the
Internet using multiple data transfer channels simultaneously. can anybody could help me about this?

You mean from multiple sources?
So your computer is going to download something from 15 servers for example?
So
1. Find a standard that defines this.
2. Search for a java API that implements it.
3. If 2 doesn't exist then implement it yourself.
Note that you should not attempt the above if you do not already understand how java sockets and threads work.

Determining HTTP download speed

Hi,
I'm currently developing a multi-threaded download manager. Now how do I determine the download speed of files. Is dividing the no. of KBs by time elapsed the only option? Does Java provide any facility to determine the connection speed directly?

Well, thanx!!
I just wanted to know if I'd reinvent something or if at all there was a better way.
Anyway I'd go ahead with KBs / time.

Could oracle provid https or ftp download?

As we know,http download is unsafety,it's easy to redirected to another download place by add a http 302 "Moved Temporarily" response code.So,could oracle java download site provide https download,just like chrome and firefox download site? Or provide a ftp download site?
Thanks,
John

You currently have a proxy configuration set to Server:mpa.one.microsoft.com:443
That's what's messing your connection, you can change this in Internet Explorer's Internet options, that change should reflect on Firefox.
Try disabling the proxy, in this case, reading the 3rd-party tutorial at [http://www.ehow.com/how_2033232_change-proxy-settings.html external link]

Can't download via the direct link for IE (HTTP 403 Forbidden)

Win7 Pro SP1 32-bit
IE 10.0.9200.16635
When I try to download/install from http://get.adobe.com/flashplayer/ I get the "cannot contact reliable source", so I then tried the Direct link for ActiveX/IE:
http://download.macromedia.com/pub/flashplayer/current/support/install_flash_player_ax.exe
and I get a HTTP 403 Forbidden. I have also tried that link in Firefox and Opera, but all I get is an empty page. I've also tried with antivirus off, firewall off etc... no luck.
BUT... If I try the second direct link(Plug-in/All other browsers)
http://download.macromedia.com/pub/flashplayer/current/support/install_flash_player.exe
it works in both IE, Firefox and Opera.
Then I started up an old XP PC just to compare, and the download ActiveX version were succesful.
Why doesn't the direct link for ActiveX work on my Win7 PC, regardless what browser I use?
(I have never had any problems with updating/installing Flash Player before, on any computer including my Win7)

Maybe I was unclear: The "Direct Links" I referred to, ARE the offline installer links.
The link Flash Player for ActiveX (Internet Explorer) doesn't work(forbidden access),
but the link Flash Player Plug-in (All other browsers) works.
BTW, is there perhaps any other URL to a offline installer, besides the one that doesn't work on my PC?
(http://download.macromedia.com/pub/flashplayer/current/support/install_flash_player_ax.exe)
Added screenshot of trying to download offline installer
