• Cannot use WPG_DOCLOAD.download_file to Apex 4.2.1

  Hi guys,.

  I came across the following problem. We recently migrated Apex 4.0 to 4.2.1 and a procedure to open an RTF document filled with the settings of a selected folder.

  He has always worked with the a procedure that calls the following line: WPG_DOCLOAD.download_file ()l_doc();

  
  

  Now, 4.2.1 it does nothing, does not give an error if a push of the button.

  
  

  Everyone knows the same problem? I already searched the internet but never found a solution.

  
  

  Thanks in advance.
  

  After all the answers, I wonder if there was some communication problems.

  Your process code should look like this:

    l_filename := r_brief.template_naam;
    l_mime_type := r_brief.template_mime;
    v_document_clob := GEN$PL_UTILS.blob_to_clob(r_brief.template_blob);
    v_document_clob := GEN$PL_UTILS.replace_tags_in_clob(v_document_clob , tab_temp_tags_values, tab_temp_toegelaten_tags, v_replace_error);
    l_doc := GEN$PL_UTILS.clob_to_blob(v_document_clob);
    l_length := DBMS_LOB.getlength(l_doc);
    htp.init;
    OWA_UTIL.mime_header (l_mime_type);
    HTP.p ('Content-length: ' || l_length);
    HTP.p ('Content-Disposition: attachment; filename="'||REPLACE(REPLACE(SUBSTR(l_filename,INSTR(l_filename,'/')+1),CHR(10),NULL),CHR(13),NULL)||'"');
    OWA_UTIL.http_header_close;
    WPG_DOCLOAD.download_file (l_doc);
    apex_application.stop_apex_engine;
  

  Notice the init of lines 7 and the stop_apex_engine at the ned.

  For the test of htp.p ('Hello'), just replace line 12, but we would like to lines 7-11 it to replicate the download.

  In addition, because you want to stay on the same page.  In my opinion, this code should be on the processes that are running on the Page rendering side of things.

  I hope this helps.

  Thank you

• wpg_docload.download_file to download a compressed... file does not

  I work with APEX 4.1
  
  Within the application under development, it is a requirement to be able to select several lines in an interactive report, then click a button to download them in ZIP file.
  
  Currently, a field that contains a list delimited by two points of ID values to determine which rows to download, like ": 17:127:
  
  By submitting the page files are selected and zipped through a process, then downloaded by the same process.
  
  This is the process of PL/SQL for zip and download:

  declare
    g_zipped_blob blob;
    b_dl_file BLOB;
    v_filename VarChar(1000);
  
  begin
  
  for rec in ( select FILE_ID, FILENAME, FILE_BLOB
  from DD_FILES
  where instr(:P9_FILE_ID, ':' || FILE_ID || ':') > 0)
  LOOP
  
    zip_blobs.add1file( g_zipped_blob, rec.FILENAME, rec.FILE_BLOB );
  
  end loop;
  
    zip_blobs.finish_zip( g_zipped_blob );
  
    select sysdate into v_filename from dual;
  
    owa_util.mime_header( 'application/octet', false );
    htp.p('Content-length: ' || dbms_lob.getlength(g_zipped_blob));
    htp.p('Content-Disposition:  attachment; filename="'|| v_filename ||'.zip"');           
    owa_util.http_header_close;
    wpg_docload.download_file(g_zipped_blob);
  
   --dbms_lob.freetemporary( g_zipped_blob);
  end;

  add1file and finish_zip are stored procedures.
  
  Currently, by pressing the button, nothing happens (but the page is submitted, nothing seems to be happening), although when the testing process, it returns what seems to be a text version of the BLOB (within the section of the workshop SQL SQL commands).
  
  A few reasons why this is happening?
  
  Already posted this in the section of PL/SQL, but it seems to have been ignored.

  Hello

  Rather than present the page I would try to open a new page (for example, by calling popUpNamed) passing the ID as a parameter to this page. Then have your download process as a before the process of header on this page.

  Use apex_application.g_unrecoverable_error: = TRUE; at the end of your code to make sure that nothing on the page that deals with this page is actually executed.

• Download BLOB via wpg_docload does not

  Hello
  I installed a new oracle database server and recently installed the 4.1 Apex then transferred my legacy data and applications from the old server.
  My new configurations are

  Previously I had Apex 4.0.1 on Apex listener through the Glassfish server and all my applications worked perfectly. But on the new installation of the page that downloads report, via the rtf code generation and it downloaded from the BLOB does not work.

  Hi sabir786,

  I had exactly the same problem. I went to my request of APEX 4.0 and Oracle 10 g to 4.1 APEX and Oracle 11 g, then all download functions via wpg_docload stopped calling the download dialog box.

  Now, I tried some kind of workaround to find the feature.
  Rather than use page-processes to call the download functions, I tried to use enforcement procedures (called on request) and it works fine.

  that is to say:
  an application process named 'export' called at the request

  Start
  (#OWNER) # .f_export
  v_EXPTYP =>: P10_EXPORT_TYPE,
  v_ID =>: F_PROJEKT_ID
  );
  end;

  a button that calls a branch with the following query

  APPLICATION_PROCESS = export

  f_export is the function that generates the rtf file and in the end, it has the wpg_docload functions to download the file.

  Hope it helps you as well.

  This has something to do with the CGI environment initialization. (I used owa_util.mime_header several times in versions of Oracle Database 11 g, but not been confronted with this error)

• Preview of a PDF document

  APEX 4.2

  Oracle 11g

  I would like the user to preview a form (document) front of e-mail or print it.

  I have a database table called FORMS_LETTERS. The table contains all the forms that can be distributed.

  

  I create a page that contains a box containing two elements. The first element (Pxxx_ID) contains the ID of the table, the 2nd itme (Pxxx_DOCUMENT) is an element of display_image I want to display the pdf file; the source is BLOB_CONTENT. :

  

  When I run the page, I get the following screen. I need to right click and choose View Image to see a preview of the document. I want to automatically preview (i.. e, without right clicking and clicking on picture).

  

  How to achieve this?

  Robert.

  > The 2nd itme (Pxxx_DOCUMENT) is an element of display_image I want to display the file pdf. the source is BLOB_CONTENT

  A PDF file is not an image, so that does not work like that.

  You can embed a PDF document to preview. Google for "html embed pdf" or something like that, for example:

  Recommended method to incorporate PDFS into HTML? -Stack overflow

  Or specifically for Apex, for example

  View PDF on the APEX region

  In Apex, you generally just download a PDF helpwpg_docload.download_file.

  There are many examples that we would find too.

  Our company has a new requirement where we must pass several SQL queries (which report queries will be stored in the shared-> components) and which must be downloaded into SEVERAL spreadsheets (.) XLSX format) using report layouts.

  1. is this a feasible requirement using any plugin?

  2. is it a feasible requirement using Oracle BI Publisher (we are willing to invest on licenses, if we can see all POC is already done)

  Please shed some light on it.

• How to create a text file of apex

  Hello.

  I have apex 5 user and I need to create a txt file to format a report ANSI classic interactive report or query.

  I need a TXT, CSV file because this file allows it to import into another application.

  Is it Possible? How?

  Thank you!!

  Hmm, could be done in a select statement in a variable:

  DECLARE l_Clob_Item CLOB;

  l_Length NUMBER;

  SELECT Col1 | Col2. COL4 IN l_Clob;

  l_Length: =.DBMS_LOB.GETLENGTH( l_Clob);

  Next, you need to write code to allow download of the clob machine local users

  owa_util.mime_header('application/octet', FALSE );
  htp.p('Content-length: ' || l_length);
  htp.p('Content-Disposition: attachment; filename="My_text_File"');
  owa_util.http_header_close;
  wpg_docload.download_file( l_Clob );
  apex_application.stop_apex_engine;

  Something like this should work...

  Thank you.

  I did worked putting just one extra line in my l_xml_body in the XML (Code 2 used). Now my excel generates with cells type 'Text' and there are no left falling to zero. Also the columns display not scientific format as 2.3D + 12. Current recording shows without default formatting.

• Picture is not displayed in the photo gallery

  Dear friend,

  Apex worm 4.2.6

  I want to create a photo gallery in my application so

  I create a page and try a code to view images in the Gallery, but Image is not displayed in my Gallery.

  I have tried to create the gallery as below link Photo Gallery

  http://www.jssor.com/demos/image-gallery.html

  Please, help us create like this gallery.

  I create the sample page in my workspace. Please follow below reference identifiers

  Application 92353 - Gallery

  Page n - 2

  
  

  Please help us.

  
  

  Thank you
  

  Hi Maxence,

  Created sample in your Application of 92353-> Page 7 - dynamic photo gallery (as mentioned in approach).

  Does the following on page 7:

  • Article "HTML Header" of the deleted page the JS code and moved the folder references to the 'file URL' and moved the JavaScript about cursor to 'Function and Variable global statement' in Page attributes-> JavaScript section.
  • Removed the CSS code in "Source of the region" and moved to the Page attributes-> CSS-> section Inline.
  • ODP created to download the images as mentioned in the blog post from Joel mentioned above:

  begin
      for c1 in (select *
                   from gallery_image_dtl
                  where id = :FILE_ID) loop
          sys.htp.init;
          sys.owa_util.mime_header( c1.mimetype, FALSE );
          sys.htp.p('Content-length: ' || sys.dbms_lob.getlength( c1.service_image));
          sys.htp.p('Content-Disposition: inline; filename="' || c1.file_name || '"' );
          sys.htp.p('Cache-Control: max-age=3600');  -- tell the browser to cache for one hour, adjust as necessary
          sys.owa_util.http_header_close;
          sys.wpg_docload.download_file( c1.service_image );
          apex_application.stop_apex_engine;
      end loop;

• Display PDF in a PL/SQL region - APEX 4.2

  I'm trying to display a pdf file in a PL/SQL area in the same page APEX. First of all, I went through the following threads, but none of them worked for me:

  How to display the pdf file in the apex region

  Re: Display pdf

  View the PDF...

  I have a dynamic region of PL/SQL with the source:

  declare
  
  n_file_id number;
  v_file    varchar2(255);
  v_source  varchar2(255);
  
  begin
  
  v_source := 'MAXIS_RENEWAL.DRIVER_FILE_API.download_file_upload?p_file='||:P250_X_FILE_ID;
  
  HTP.P(V_SOURCE);
  
  htp.p('<div style="">');
  htp.p('<embed height="900" width="800" name="embed_content" src="'||v_source||'" type="application/pdf" />');
  htp.p('</div>');
  
  end
  
  

  The download_file_upload procedure is as follows:

  PROCEDURE DOWNLOAD_FILE_UPLOAD(p_file in number ) AS
  
  
          v_mime  VARCHAR2(4000);
          v_length  NUMBER;
          v_file_name VARCHAR2(2000);

                  -- set the size so the browser knows how much to download
                  htp.p('Content-length: ' || v_length);
                  -- the filename will be used by the browser if the users does a save as

  exception when others then
     --log error
  
  
     htp.p('ERROR DOWNLOAD FILE: '||sqlerrm);
  end download_file_upload;
  
  

  With the current version, it only downloads the pdf on FireFox and IE. On Chrome, it will not. It will display only the string 'MAXIS_RENEWAL. "DRIVER_FILE_API.download_file_upload? p_file = xxxsomeID" in the region.

  When I copy the string and passed in the url of the browser, it downloads the files.

  I can't really understand the problem. Any help is deeply appreciated.

  v_source: = ' MAXIS_RENEWAL. DRIVER_FILE_API.download_file_upload? = p_file'|: P250_X_FILE_ID;

  Is it possible to hide this?

  Yes, I think that you have kept the following line in your PL/SQL dynamic content area, that is why it displays:

  declare 
  
      n_file_id number;
      v_file    varchar2(255);
      v_source  varchar2(255); 
  
  begin 
  
      v_source := 'MAXIS_RENEWAL.DRIVER_FILE_API.download_file_upload?p_file='||:P250_X_FILE_ID; 
  
      -- remove this line from your code
      -- is this for debugging purpose?
      -- HTP.P(V_SOURCE);
  
      htp.p('
  ');
      htp.p('');
      htp.p('
  '); 
  
  end;
  

  I hope this helps!

• APEX 4.2.3 consume the web service returning a PDF problem

  Using APEX 4.2.3 on a database of Oracle 11 g R2, Firefox 31.7, we ask a service web restful one before the process of page header, to download a PDF Code file used:

  declare

  CLOB l_clob;

  l_dest_offset integer: = 1;

  l_source_offset integer: = 1;

  l_Json VARCHAR2 (4000);

  l_clob: = null;

  DBMS_LOB.CREATETEMPORARY (l_blob, true);

  hr_Pkg.call_rest_webservice (l_Json, 'TestME.Pdf', l_Clob);

  Logger.log ('CLOB SIZE IN PAGE: ' | sys.) DBMS_LOB. GetLength (l_clob));

  sys. HTP.init;

  sys.owa_util.mime_header (' application/pdf', FALSE, 'UTF-8');

  apex_application.stop_apex_engine;

  exception when others then

  sys. HTP. PRN (' error: ' |) SQLERRM);

  apex_application.stop_apex_engine;

  end;

  We run in the question, that the PDF file is empty with the exception of a few fill-able fields that must be completed in advance by the call to the web service.

  When you run the web service directly from the browser, the PDF that is generated is very well and seems to be complete. And the size of the file that is created as the clob from the web service call is exactly the same size it as the pdf file received directly from the web service.

  When we compare the size of the clob to the size of the blob, we see that the blob is slightly larger in size than the clob.

  Any suggestions? (Sample code for posting to the hosted site for Oracle will not work because you can not call the hosted instance web services and web service is hosted BEHIND our firewall).

  Problem is resolved... As opposed to the use of the APEX apex_web_service.make_rest_request must use the utl_http.begin_request and then treats the query returned through utl_http. READ_RAW and who then saving it in a temporary BLOB.

  Maybe when we update to the APEX 5, I'll see if I can deal with it using standard APEX packages...

• Display an image BLOB in a report of the APEX

  Hello

  I have a BLOB column in a table that contains an image I want to display in a report.

  The table definition for the table (MAG_IMAGES) that I store the BLOB in is:

  CREATE TABLE 'MAG_IMAGES '.

  (NUMBER OF 'MAG_IMAGE_ID',

  VARCHAR2 (200) "NUMERO_IMAGENOM_IMAGE."

  BLOB "CONTENT."

  'MIME_TYPE' VARCHAR2 (1000).

  NUMBER OF "DOC_SIZE."

  'CONTENT_TYPE' VARCHAR2 (1000).

  VARCHAR2 (20) "DISPLAY_AREA."

  TIMESTAMP 'LAST_UPDATE_DATE' (6).

  ENABLE 'MAG_IMAGES_PK' CONSTRAINT PRIMARY KEY ('MAG_IMAGE_ID')

  )

  /

  It's the Vendor_Group Table where I store the Image_Id.

  CREATE TABLE 'VENDOR_GROUP '.

  (NUMBER OF 'VENDOR_GROUP_ID',

  VARCHAR2 (100) "VENDOR_GROUP_NAME."

  "IMAGE_ID" NUMBER

  ENABLE 'VENDOR_GROUP_PK' CONSTRAINT PRIMARY KEY ('VENDOR_GROUP_ID')

  )

  /

  I created the following procedure IMAGE_DISPLAY, which I have from a previous discussion forum.

  create or replace PROCEDURE image_display (p_image_id number)

  AS

  l_mime VARCHAR2 (255);

  l_length NUMBER;

  l_file_name VARCHAR2 (2000);

  l_content BLOB;

  BEGIN

  SELECT content, Mime_type DBMS_LOB.getlength (content)

  IN l_mime, l_content, l_length

  OF mag_images

  WHERE mag_image_id = p_image_id;

      

  OWA_UTIL.mime_header (NVL (l_mime, "application/octet"), FALSE);

  HTP.p ("Content-length: ' |") l_length);

  OWA_UTIL.http_header_close;

  WPG_DOCLOAD.download_file (l_content);

  EXCEPTION

  WHEN OTHERS RAISE.

  END image_display;

  I then create a region of APEX report with the following source:

  Select a.group_product_list,

  ' < img src = "image_display? p_image_id =' | NVL(a.image_id,0) | "" height ="" | 100. "" / > "photo

  vendor_group a, mag_images b

  where image_id = b.mag_image_id (+)

  and mag_vendor_id = 2;

  The Image does not appear, but it looks like this below. I put the column attribute 'Standard report Column '.

  

  Can someone please tell me what I'm doing wrong?

  
  

  Thanking you in advance

  Hello

  I tried to recreate the region from scratch, even in another page altogether but still no luck.

  If I run the report without defining the column in a BLOB with its attributes (MIMETYPE column, Table etc.), he does not fail, but returned the following, which is of course the length of the BLOB. The problem only occurs if I set the attributes. Any other suggestions?

  

  Include MAG_IMAGE_ID as a hidden column in the report.

  So I think that you must provide the credentials of developer to your workspace on apex.oracle.com so that we can investigate the problem.

  examples uploading files a better way

  See page 6 of the database Application example.

  There is also a tutorial OBE which followed the introduction of the declarative BLOB support in 3.1 that is always topical in 4.x.
