Get a file of 1 MB to a web service

Hello

I'm trying to get a file of 1 MB, call a web service from a 10.2.0.5. Everything works well except the conversion of the SOAP to an XMLTYPE response. I get the error ORA-00932-> ERRO:-ORA-00932: inconsistent data types: expects a return value is an instance of a user defined class Cabriolet Java to an Oracle type got an object that cannot be converted. When I get a smaller file conversion works perfectly. No idea how to solve this problem?

Here is my code:

I'm not familiar with the UTL_DBWS package myself. I use the UTL_HTTP to make Web services.

I think your problem is probably the answer is greater than 32K and therefore must be obtained in pieces. In my code, it's a bit like this...

  PROCEDURE p_soap_request(p_username IN VARCHAR2, p_password IN VARCHAR2, p_proxy IN VARCHAR2) IS
    soap_request  VARCHAR2(30000);
    soap_respond  CLOB;
    http_req      utl_http.req;
    http_resp     utl_http.resp;
    resp          XMLType;
    soap_err      exception;
    v_code        VARCHAR2(200);
    v_msg         VARCHAR2(1800);
    v_len number;
    v_txt Varchar2(32767);
  BEGIN
    IF p_proxy IS NOT NULL THEN
      UTL_HTTP.SET_PROXY(p_proxy);
    END IF;
    -- Define the SOAP request according the the definition of the web service being called
    soap_request:= ''||
                   ''||
                   '  '||
                   '    '||
                   '      '||p_username||''||
                   '      '||p_password||''||
                   '    '||
                   '  '||
                   '';
    http_req:= utl_http.begin_request
              ( 'http://www.website.net/webservices/GetDetailsService.asmx'
              , 'POST'
              , 'HTTP/1.1'
              );
    utl_http.set_header(http_req, 'Content-Type', 'text/xml');
    utl_http.set_header(http_req, 'Content-Length', length(soap_request));
    utl_http.set_header(http_req, 'Download', ''); -- header requirements of particular web service
    utl_http.write_text(http_req, soap_request);
    http_resp:= utl_http.get_response(http_req);
    utl_http.get_header_by_name(http_resp, 'Content-Length', v_len, 1); -- Obtain the length of the response
    FOR i in 1..CEIL(v_len/32767) -- obtain response in 32K blocks just in case it is greater than 32K
    LOOP
        utl_http.read_text(http_resp, v_txt, case when i < CEIL(v_len/32767) then 32767 else mod(v_len,32767) end);
        soap_respond := soap_respond || v_txt; -- build up CLOB
    END LOOP;
    utl_http.end_response(http_resp);
    resp:= XMLType.createXML(soap_respond); -- Convert CLOB to XMLTYPE
  END;

[ADF, JDev 12.1.3] Pop-up window to see the or download a PDF file that is returned by a Web service method

Hallo,
in a page of my web application, I need to add a button that when clicked shows a PDF in a pop-up window which enables the user to download on the PC.
To get the file PDF, the application must call a Web service method that returns the contents of the file encoded in base64 in the body of the response. If the request does not get the file, but a stream that must be dealt with to get the file.
Could you kindly advice me a good approach/tutorial to create this feature?
Thank you and best regards,
Federico

Call your servlet ws, then convert bytes of payload in base64 and returns this as a binary stream.

Client side, you can use af:inlineFrame component inside the af: popup to call your servlet.

I get a file (pixel.cgi) who wants to download when I use certain sites (Groupon / Thomas Cook).

I get a file (pixel.cgi) who wants to download when I use certain sites (Groupon / Thomas Cook). I scanned my mac for the virus, but none can be found.

The page has at least 3 forms invisible that automatically submit to securepaths. com which is probably some sort of tracking site. The site sends answers normally capable of managing internal Firefox, so I don't know why you're getting invited to record in the form of a download.

The standard approach to download actions wrong is to be wary of corruption of the settings file that stores these settings. You can rename the file and Firefox to regenerate to see if that solved the problem. (You will need to review the Applications section of the Preferences dialog box to reselect the default preferences, such as your favorite email client and the PDF Viewer).

Here's how:

Open the settings folder (AKA Firefox profile) current Firefox help
- button "3-bar" menu > "?" button > troubleshooting information
- (menu bar) Help > troubleshooting information
- type or paste everything: in the address bar and press enter/return
In the first table in the page, click the "Show in Finder" button (in Windows: "Show the file")

Leave this window open, switch back to Firefox and output, either:
- "3-bar" menu button > button "power".
- (menu bar) File > exit/Quit
Pause while Firefox finishing his cleaning, then rename the mimeTypes.rdf to something like mimeTypes.old

Launch Firefox back up again. Any improvement in the research Manager pixel.cgibar?

In case they are of some interest, I have attached the screenshots showing:

(1) the web console (command + Alt + k) - showing that the request to this site is a PUBLICATION, which generally indicates a sending a form or submission script

(2) source of the generated page (select all, right click, view selection source, find pixel.cgi, select all)

(3) the network tab of the web console, indicating the nature of the data being sent back to the site after the POST

The iPad does not support USB keys. There are some wireless flash drives that can be used, but not the classical records. I suggest you transfer files to a computer and their synchronization then back to the iPad via iTunes.

Use bookmarks > organize bookmarks > import and backup > export HTML and make sure that you give the file an extension of .html file.

GET the file of cRIO using WebDAV - error (363510)

Hi all

Hoping for a little help with an error I can't cross. I am trying to get a file off my cRIO and onto my PC using the webDAV Protocol. I know there are other ways to do this, but really, Ide like to this way of working. I am sure that this is not a problem with my path of the file. The error says "Error writing to the socket" which makes me think maybe Windows prevents LabView to write the file on my local computer? I tried using the HTTPS protocol on port 443 so with the same result. One thing I am suspicious of is that I am connected directly to my cRIO on my secondary ethernet card and windows it is considering a "public network". I can't change that, but I have disabled the windows firewall, thinking that perhaps that had something to do with it.

Thank you

Corey

I got it to work. Turns out that "local file path" needs the full path, including the name of the file that will be written. This is in contradiction with the help file for the VI GET of WebDAV. The help file says that simply give the path of the directory that is written to the file.

Is it possible to get the files for windows vista, so I can reinstall my system?

Hello

Im a user of linux on one machine HP Pavilion dv5-1095eo leisure. IM tired to restart my machine to run a windows OS, so is possible for me to get the files for windows vista. I got the windows key attached under the computer and I don't have any windows CD when I brought the machine.

Hello:

You can do your own installation disc Vista too if you wish.

If you can read your 25-character product key MS, you can make your own Windows Vista installation disc. You just download the 3 files you need on the link below and read all the instructions to create a Setup bootable DVD disk using imageburn.

When I went to compile the ISO file, ImageBurn gave a message on a WIM file, file and ISO, and if I wanted to burn it in a different format.

I selected no, make the ISO file.

It was not so hard to do. I burned both the disk of 64-bit and 32-bit disk in case I ever need them.

I tested both of them (just before going forward with the actual facility) and they seem to work perfectly.

Apparently, when you enter the product key, he knows which version of Vista you have.

http://en.community.Dell.com/support-forums/software-OS/w/microsoft_os/3317.2-3-Microsoft-Windows-VI...

After you have successfully installed vista, you can download the drivers you need your PC support and driver page.

I want to get a file on my hard drive of the cRIO to my host PC. I did it by using the FTP Get file vi. After you save this file in my host PC, I want to delete the file on the cRIO. Is there a direct way to transfer the file to the host PC cRIO or do I have to manually delete the file.

I found what was causing the problem, it was a program that I downloaded from CNET that detects programs on my PC and lets me know if there are updates for them. I disabled and uninstalled the program and now I only get the file installer_msi_win.msi popping up. Follow this link, it helped me when I was able to track down the installed program...
