Mangled file downloads over http problem in 10g

I have a web app running in an OC4J stand alone 10.1.3.3 and am having a problem with downloading files over http. Its a struts2 app whose file downloading impl is easy to use and standard code for writing to an http servlet response output stream.
Using the firefox plugin for Live Headers I can see that the headers are correctly added to the servlet response and I do get the file I want. However the file has been mangled with binary output around the text. This is the case for txt, word, or any other file.
This problem does not occur in Jetty or Tomcat. I've also ruled out file corruption while going in/out of the database since I can upload a file when running oc4j, turn off oc4j, start up my app in Jetty and retrieve the same file just fine.
The mime types are all accounted for and the problem exists regardless if I use a specific content type or just application/download. My browsers (firefox and ie) also recognize all files from the content disposition value "attachment; filename=myfilename.ext". Its just the file content that some how has been wrecked on the way out of the container.
Has anyone experienced this? I only found one or two unanswered posts elsewhere.
How can this be mitigated?
Thanks in advance.
Andrew

Figured it out when I realized it was in fact the data coming from the database that was corrupt. There were some older posts on the hibernate website that pointed to a single property that needs to go in the hibernate.properties file: hibernate.jdbc.use_streams_for_binary=true. Without it, Oracle returns the Blob locator consistently 86 bytes in length and therefore bad binary.

Internet Explorer cannot download over HTTPS if Pragma: no-cache is set

APEX Ver. - 3.2
DB Ver. - 11.1.0.7
Problem : The apex application generates an XML file and saves it to a table. Users navigate to a report where they have a DOWNLOAD link to download the file. Over HTTPS, when the download link is clicked Internet Explorer (IE7) generates an Error Message saying Internet Explorer cannot download apex_util.get_blob from ...
The same functionality works in Firefox and Chrome.
A blog post on MSDN (http://blogs.msdn.com/b/ieinternals/archive/2009/10/03/internet-explorer-cannot-download-over-https-when-no-cache.aspx) describes this problem and one of the reasons contributing to this problem is a pragma declaration of no-cache , is there a way to remove the pragma declaration in the request header?

Dear Markus
Could you please tell me indetail...
Im able to download if im in internal network, bz it is directly pinging from server in IE 6.0 and 7.0. Problem is only with External facing, that too with IE 6.0, 7.0. In firefox im able to downlad the file even using reverse proxy , and internal network.
What i guess is problem within reverse proxy setup & configurations or IE broweser.?
Please suggest

Hi Brian,
I have the same problem as Ajay Yeluguri. In http mode I can generate a download of an Excel document but when we use the portal in https it doesn't work.
When I try to download using https it does not pull the file name and path and when I choose download I have a error message : "Internet Explorer cannot download from ..."
I've test the point 3.2 "... including file up/download" of the BSP application IT00 and it works fine in http and https mode. My problem is not the upload but the download. And in this application the uploaded document is opened in the Internet Explorer window but I want to generate a Save as... window to download the file.
Have you an idea what i can do to solve my problem.
Thanks

Sending audio data over http problem

Hi Guys,
We are trying to create a little servlet in Tomcat, which is capable to send audio files over http to an embedded media player. The definition of the player looks like:
<OBJECT ID="Mp" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" TYPE="application/x-oleobject" WIDTH="0" HEIGHT="0">
<PARAM name="uiMode" value="none">
<PARAM NAME="ShowControls" VALUE="0">
<PARAM NAME="AutoStart" VALUE="1">
<PARAM NAME="ShowPositionControls" VALUE="0">
<PARAM NAME="ShowStatusBar" VALUE="0">
<PARAM NAME="ShowDisplay" VALUE="0">
</OBJECT>
<script language="javascript">document.Mp.URL = "here comes the url of the servlet with item ID";</script>
The servlet reads the audio file and writes its content to the response with the following http header settings:
getResponse().setContentType("audio/x-wav");
getResponse().setHeader("Content-Transfer-Encoding", "binary");
getResponse().setHeader("Pragma", "Public");
getResponse().setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
getResponse().setHeader("Content-Disposition", "inline; filename=Media.wav");
getResponse().setHeader("Content-Length", new Integer(MediaBytes.length).toString());
getResponse().setHeader("Accept-Ranges", "bytes");
So, everything works fine for wav files in Internet Explorer, but we are facing problems with Firefox, where it does not work. The embedded Media Player says that "Windows Media Player cannot play the file. One or more codecs required to play the file could not be found."
But if we set the url to directly to the file on the server, everything works fine.
We have analyzed the HTTP traffic in both situation, but we cannot understand how Internet Explorer/Firefox and Media Player works together:
- how does Media Player know that the audio file is playable?
- if the url points directly to the file, the HTTP headers does not contain any kind of information about the file type, only the extension is available; Media Player checks the file extenion in the url?
- if the url points to the servlet, why Media Player in Firefox cannot determine the file type and throws error?
Any help is greately appreciated!
Thanks!
Gabor

If you haven't already, I would try breaking down the problem. First confirm you're getting serial data then confirm that netcat can send some data. Like this:
xxd < /dev/tty.usbmodemfa121 | less
nc -u 10.0.1.3 7000 <<< 'hello over there'

FILE Adapter over HTTP

Hi,
Does anybody know if File Adapter woks with files over http?
For example:
I have a CSV file at http://xxx.com/file1.csv, I want to process this file and send to RFC Adapter.
Can I put "http://xxx.com/" in "Source Directory" of file sender communication channel?
Any sugestions? (FTP is not a choice)
regards,
Luiz Alberto

Hi Luiz,
I don't think this will work with File Adapter.
Thanks and Regardds,

File upload over HTTP into IFS

The webui classes provide functionality to upload a file over HTTP as multipart/form-data. It takes care of splitting out the boundaries, and other form data, leaving just the file to store in IFS. My question is this:
1. Since the webui classes are not a part of the API, are they supported for development purposes? (i.e, can I mimic the behavior of the webui in my application?) I suspect not.
2. Why doesn't the IFS API provide the ability to handle multipart/form data over http? Even the webcommandapp example application assumes the file is already local to the webserver computer, which leads me to believe it's my responsibility to get it there over HTTP or FTP.

I think the best way out for now is to use the Oreilly classes that are available at : http://www.servlets.com/resources/com.oreilly.servlet/
to handle the multipart-form data;until Oracle provides this feature in a later release of the ADK

MapViewer 11g over https problem - how to solve ?!?

Hi,
anyone able to access mapviewer 11 g deployed on standalone OC4J 10.1.3.4 over Https ?
Namelly, the following link works:
https://localhost/mapviewer/
_but, going on the 'Demos' tab, and clicking on the 'maps and faces' link ( https://localhost/mapviewer/faces/fsmc/oraclemaps.jspx ) - produces the following javascript error:
[Exception... "Access to restricted URI denied" code: "1012" nsresult: "0x805303f4 (NS_ERROR_DOM_BAD_URI)" location: "https://localhost/mapviewer/fsmc/jslib/oraclemaps.js Line: 6497"]Anyone able to access mapviewer (deployed on any server) over https ?

MapViewer works over HTTPS with some minor configuration changes. First, you may need to tell MapViewer to return generated map image URLS in the form of "https://...", which is done in the config file mapViewerConfig.xml through the <save_images_at> element.
From the error message it does seem to indicate maybe the JavaScript API (oraclemaps.js) is being loaded from "http://" while the web page itself is accessed via "https://" and browser thinks they are two different domains. Maybe you can change how the JS library is loaded in your page and see if that fixes the issue?

NFC File share over WiFi problem between camera - Q10

Hello Folks, I just got myself a Olympus camera with a WiFi NFC photoshare feature. I cannot get it to work with the Q10. Camera Side: WiFi enabled - the display shows a NFC Tag and also provides instructions for manual connexion.When I scan the tag with smarttag I get this string "OIS1,CP1%1H1UOP+++Y//,%*Z-+-X$" and the Q10 wants to search it in google (LoL)So I established the WiFi connexion manually as instructed by the Camera. The Q10 establish the connexion but warns about Internet not available with it. The camera instructions says the files are at http://oishare/ No matter how I try to enter this http://oishare/ link, the Q10 keeps sending it to Google where it get lost in translation. Does anyone has figure out that one out? Thanks folks

Thread update Network / Mobile Network must be turned off (at least data) in order to be able to access http://oishare/Then I managed to see the directory structure but I couldn't find any pictures on the camera. Later on, I found some instructions in other forums to Sideload the Snap Google Play client.With a Google Play account in hand via Snap, I downloaded and install the Olympus Photoshare app. The app installed properly and has its own NFC scan function compatible with the Camera NFC tag. I was then able to export the pictures to the Q10 and even remote control the Camera. Pretty cool.

File download dialog box problem!

Hi,
How do you force file download message box to use specified file name instead of JSP or servlet name.
I am using:
// code in attachment.jsp
<%
response.setContentType(mimeType.trim());
response.setHeader("Content-Disposition","attachment;filename=\""+attachmentViewBean.getAttachmentName()+ "\"");
%>
With the above code, browser first pop up file download dialog box informing
'You are downloading the file:[attachment.jsp] from host. Would u like to open the file or save?'
I want the file name that I had specified in setHeader("Content-disposition","attachment;filename=resume.doc") to appear(i.e. resume.doc) in above dialog box and not the servlet name.
Any suggestions/tips on this?
Your help would be greatly appreciated.
Thanks,
Yogesh

For saving the document I have used -
res.setHeader("Content-disposition", "attachment; filename="+ FileName );
and it is working very fine, it saves the document with name specified in FileName
For opening the file in browser without any prompt-
res.setHeader("Content-disposition", "inline" );
For setting the content type -
try {
     if(FileType.equalsIgnoreCase("pdf")) contentType = "application/pdf";
     if(FileType.equalsIgnoreCase("doc")) contentType = "application/msword";
     if(FileType.equalsIgnoreCase("rtf")) contentType = "application/msword";
     if(FileType.equalsIgnoreCase("gif")) contentType = "image/gif";
     if(FileType.equalsIgnoreCase("jpg")) contentType = "image/jpeg";
     if(FileType.equalsIgnoreCase("html")) contentType = "text/html";
     if(FileType.equalsIgnoreCase("htm")) contentType = "text/html";
     if(contentType == null){
     contentType="text/plain";
     res.setContentType(contentType);
} catch (Exception e){
          out.println("Exception while setting content type");
          out.println("Exception : " + e);
          return;
Hope this helps

RTMP over HTTP problem

Hi all; i am new on steaming & flash server; when we try to use RTMP over HTTP the outside client gets the internal IP address of the FMS server instead of the NAT one or public IP address, how can we solve this. Thank for the help in advance.
Thanks

Unfortunately a lot of this depends on your NAT. It's not entirely clear where your NAT is, and where the server lies relative to it. Typically we're talking about clients that can poke a hole out of the NAT, and thus they would typically appear to have an IP that maps back to the NAT as needed. If it's the reverse and the FMS server is on one side of a proxy and can be reached - in that case the proxy could report its IP via the forwarded-for field for the conector on the other side. So, I guess the answer depends a lot on config and proxy settings.

Zzxc: I am having problems with Firefox and a Google gadget score board on my Google home page. Every time I go to my Google homepage, a file called "scores.htm" downloads into my Firefox download. I can have at least 50 of those files downloaded over t

You have chosen to open “scores.htm”
What should Firefox do with this file?
-Open with: Firefox (default), or other
-Save file?
Do this automatically for the files like this one.
I chose cancel and when I rebooted the Google page the same window came up.
I don’t want to open with or it will open with something every time I come back to Google.
The best option until this is resolved is to “Save File” and that continues to down load into the “Download Firefox” folder.

When I go to my Google page with the sport scores gadget on, Firefox download, in the downloads window a file "scores.htm" everytime. Consequently I have 10's if not 100's over time of scores(1), (2)(3).htm respectively. How do I stop it?

Help........ How to download an XML file (URL) over HTTP within ESB?

Hi,
There is a requirement to download an XML file from the Web using Fusion middleware. The XML file is available as a URL, and is updated daily.
http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml
We need to check if this is download is possible from within ESB.
One Oracle consultant reported this to be slightly tricky, but possible through HTTP Binding. We never could get in touch with him again.
So open to the forum.
So please suggest your opinions, and icing on the cake if you can also point to some tutorial or sample code.
Thanks,
Amit

just run a wget on the file and then you can pick it up with a file adapter, I note there is no XSD association with it.

Problem with parsing large XML files chunked over HTTP

I'm trying to isolate a bug that was introduced when upgrading the JRE in use from Java 7u51 to 7u71 without changing any code. The problem appears to be very similar to: Bug ID: JDK-8027359 XML parser returns incorrect parsing results.
Further investigation showed that it was also introduced in the same versions (7u71) where that fix was applied. Unlike that bug though, my XML is marked as version 1.0. It also appears to be with only large XML files, on the order of 10MB or so.
The closest I've been able to narrow it down to is the code is using JAXB to unmarshall a stream that the debugger tells me is a org.apache.http.com.EofSensorInputStream / org.apache.http.impl.io.ChunkedInputStream. The exception I get is not consistent, but typically appears to be from chunks being overwritten or shuffled, resulting in letters appearing in attributes that are actually numbers, or like the following where an attribute "testAttribute" gets partially overwritten by the end of a timestamp that was in a different section of the XML.
javax.xml.bind.UnmarshalException
- with linked exception:

Here's some code that seems to reproduce it if you can connect to an XML server that returns a large chunked XML file:
SchemeRegistry registry = new SchemeRegistry();
registry.register(
new Scheme("http", 80, PlainSocketFactory.getSocketFactory()));
HttpClient client = new DefaultHttpClient(new BasicClientConnectionManager(registry));
String url = "http://someUrlReturningAlargeChunkedXML";
HttpGet method = new HttpGet(url);
HttpResponse response = client.execute(method);
InputStream inputStream = response.getEntity().getContent();
XMLStreamReader responseReader = factory.createXMLStreamReader(inputStream);
JAXBElement<JaxBObjectOfResponse> wot = unmarshaller.unmarshal(responseReader, JaxBObjectOfResponse.class);
If you connect using URL.openStream() to the same service there is no error. If I read bytes directly and write to a file, there is no error. The error only happens when I try to unmarshal it, and it's large, and I'm using Java 7u71 (or later). It can be consistently repeated with the jsp webapp that I'm using, but didn't show the error when I used the same code with a Wikipedia dump XML file.
How can I unmarshal in a different way to avoid this problem? Or, how can I better isolate the bug so it can be posted to the appropriate bug system?

Apparently, adding the Woodstox XML libraries avoids the bug. Is there anyone who can reproduce this on another system? Was there any changes to the Stax implementation between u67 and u71 that may have introduced a bug like this?
Edit: When setting the logging level to DEBUG, I once saw the overwritten buffer being logged as if that was what was received (as in the testAttribu00Z example above). I can't repeat that anymore though, and very rarely it does parses with no exception (though it may have still been corrupted). Now the error seems to be consistently on one of the buffer boundaries, as in:

Urgent: File download using HTTP

Hello,
I have some files stored on a Remote machine A. The machine A accepts HTTP connection only.
I want to write a java program which runs on Machine B, creates a connection to machine A and gets/downloads the file and store it on machine B. The file is a 3gp/mp4 file.
Can you please advise/suggest as how this can be done?
Regards.

Thanks for your reply.
I am getting the following error now, can some one please advise how to fix this:
HttpTest.java:12: incompatible types
found : java.net.URLConnection
required: java.net.HttpURLConnection
(The openConnection method returns a URLConnection object and not a HttpURLConnection object)
I also tried the below code:
URL url = new URL("http","10.176.96.63",9000,"c:\\database.properties");
InputStream is = url.openStream();
This code gives an exception:
java.net.SocketException: Unexpected end of file from server
Can someone please help...
Thanks.

File Transfer Over Network Problem since 10.4.9 Update

Since the update I've had this problem. Here's a typical operation:
In a finder window, from my PowerMac G5, I click on Network and mount a disk from another Mac on the Network (Intel Mac Mini). I navigate to that mounted disk and drag a 1.5GB file from it to a directory on my G5.
This used to take a couple of minutes before the update. Now it takes over 4 hours! My network looks like this:
Intel mac Mini (10.4.9) hard-wired to new Airport Extreme 802.11n
PowerMac G5 (10.4.9) hard-wired to new Airport Extreme 802.11n
Pwerbook (10.4.8) Wi-Fied to new Airport Extreme 802.11n
I don't understand why this is happening or how to correct this problem. Any help would be greatly appreciated since I do this operation frequently and 4+ hours is totally unacceptable.
Thanks!
G5 2.5gHz PowerMac, Mac Mini Core Duo, G3 400mHz Powerbook Mac OS X (10.4.9)

I found out that about the same time as the update one of my five external hard drives started going south on me. When it got to the point of no return where it wouldn't mount any more I took it off the Mac. The network is running fast and fine now. For some reason the drive was slowing everything up. Weird.
