PDF in APEX 3.0

In Statement of Direction for apex, among else stands:
-Print formatting improvements to support output such as Adobe PDF
Now i would like to know what kind of support, over PL/SQL(something like PL/PDF, or maybe PL/PDF itself, which i would prefer) or like in old document with FOP and Java?

Error while generating PDF from APEX through BI Publisher

Hi,
I am facing a problem which is intermittent.
I am generating a pdf from APEX which has been developed using BI Publisher.
I have linked the report to the APEX using report queries/report layouts in shared components.
The pdf used to open without any problems previously.But currently,I am getting the following error
*"An error exists on this page.Acrobat may not display the page correctly.Please contact the person who created the pdf document to correct the document."*
Once the Bi Publisher Services is restarted,I am able to generate the pdf.Again After sometime the same error pops up.
Has anybody faced the above error?
Any solution for the same.
Kindly reply.
Thanks and Regards,
K Tanna

Report Logo - Displays on HTML, not on PDF report (Apex report_)

Hi Gurus.
I thought I'd report this here, as we are having a BI Publisher error, and I'm not getting any help on the Apex subforum.
+We have a system environment setup where we have BI Publisher Enterprise and Apex 3.1.2 talking together to create PDF reports on a Oracle 10g database (R2 I think, I'm uncertain). As part of a business requirement, depending on what project you are looking at within our apex application, when printing a report you see a logo specific to the project. We have already developed this using a RTF template with a dummy image embedded, and url:{concat(.//URL,.//PROJECT_ID)} in the Alternative Text field of the Web tab of the Format Picture dialogue.+
This worked fine when using the RTF templates as Report Layouts within Apex and as templates within a BI Publisher report.
However, now logos aren't appearing.
We are on BIP 10.1.3.2 according to the Help File, and we are running Apex 3.1.2.00.02 on Dev and Apex 3.1.1.00.09 on test and prod, however none of these environments are outputting logos in the PDF reports.
Curiously, if I go into the BI Publisher interface and ask for the report to be outputted as HTML, the image shows. Running the HTML version of the report from Apex also shows the logo -- but the logo isn't showing in the PDF reports.
As I continue trouble shooting, any assistance would be greatly appreciated.

If anyone could give us any insight on this, it would be appriciated.
I'm unsure if its a permissions problem with the PDF seeing the image, or something related to server setup. We currently have a redirect in place to production that doesn't include the :7777 in the URL, and for some reason, if the G_URL for the image is changed to this portless URL, the image is embedded. However, this redirect was in place for another application, and will soon be locked down, so is not available for a long term solution to this problem

A question about error with jasperserver for pdf and Apex

I have created a pdf report on jasperserver and I can call it from apex via a url and it displays fine. The url is this format {http://server:port/jasperserver/flow.html?_flowId=viewReportFlow&reportUnit=/reports/Apex/deptemp&output=pdf&deptNo=#DEPTNO#&j_username=un&j_password=pw}
However, I am trying to follow a stored procedure executed from Apex so it would not expose the username/pwd in the url like above.
If I am reading the apache error log correctly it is erroring in this piece of the code below where it executes {Dbms_Lob.writeAppend}
loop
begin
-- read the next chunk of binary data
Utl_Http.read_raw(vResponse, vData);
-- append it to our blob for the pdf file
Dbms_Lob.writeAppend
( lob_loc => vBlobRef
, amount => Utl_Raw.length(vData)
, buffer => vData
exception when utl_http.end_of_body then
exit; -- exit loop
end;
end loop;
Utl_Http.end_response(vResponse);}
The error log says this; HTTP-500 ORA-14453: attempt to use a LOB of a temporary table, whose data has alreadybeen purged\n
What is this error telling me and how can I correct it?
The stored procedure I am following is below but replaced the vReportURL with my url like above that works.
Thank you,
Mark

I am new to working with working with jasperserver to apex interfacing, and also using utl_http with binary data.
But I guess typing my question down helped me figure out a way to make it work for me.
I combined info from http://www.oracle-base.com/articles/misc/RetrievingHTMLandBinariesIntoTablesOverHTTP.php

to come up with this procedure.

Utl_Http.set_header(l_http_request, 'User-Agent', 'Mozilla/4.0');
l_http_response := UTL_HTTP.get_response(l_http_request);
-- Copy the response into the BLOB.
BEGIN
    LOOP
      UTL_HTTP.read_raw(l_http_response, l_raw, 32767);
      DBMS_LOB.writeappend (l_blob, UTL_RAW.length(l_raw), l_raw);
    END LOOP;

EXCEPTION
WHEN OTHERS THEN
    UTL_HTTP.end_response(l_http_response);
    DBMS_LOB.freetemporary(l_blob);
    RAISE;
END download_file; }
Don;t know what I did wrong, but I could not create an 'on-demand' process to call my procedure. I did not understand what it means when it says 'To create an on-demand page process, at least one application level process must be created with the type 'ON-DEMAND'.
so I had to use a blank page with a call to my procedure in the onload - before header process and that seems to work ok.
Thank you,

PDF: Unable to print a document as PDF from APEX when using the BI Publishe

Hi,
From an APEX application, I am unable to print a document in a PDF format when using the Oracle BI Publisher.\
Here is the configuration:
1) Server A is W2K3 and hosts the Oracle BI Publisher server, with IP address ip01.
2) Server B is a OEL5.2 and hosts the database server of the APEX application, with IP address ip02.
3) Machine C is a W7 desktop from which through an URL both the APEX applicationn and the BI server are accessed, with IP address ip03.
4) The APEX application is configured with the following to use the Oracle BI Publisher:
- Printer server: Advanced (requires Oracle BI Publisher)
- Printer server protocol: HTTP
- Printer server host address: ip01
- Printer server port: 9704
- Printer server script: /xmlpserver/convert
- Network services are enabled (at least I did get any warning/error message)
From C, I access the the APEX application through its URL, if I try to download a page by selecting PDF in the download section of the interative report section for that page, I am unable to open if and get the error:
<file>. pdf file can not be opened because the file type is not supported or because it is damaged (because, for example as an e-mail attachment is not sent and correctly decoded)
Yet, still from C, I am able to open any other PDF document.
The same way, still from C, acessing the APEX application through its URL, I have a query report defined with a PDF output format. Then, when I test the report (Test Report in the Report query) for that query, I get the error:
ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.
At first sight this could be a wong entry in the priinter configuration for APEX. But with this address, through the URL I can log in to the Oracle BI Publisher server.
Does someone has an idea what the problem could be?
Thanks for any tips.

How are you trying to print to pdf?
Don't go via PostScript or Acrobat Distiller, which are old deprecated technology.
You use:
Menu > File > Print > PDF (button bottom left) > Save as PDF…

Generate pdf with apex listener 2.0

hi,
we would like to generate pdf out of apex.
as long as we have text (IRR) WITHOUT special characters (öäü), everything is working fine.
when we have this characters in a text-columng (IRR), then we get a .pdf with the following content:
javax.xml.transform.TransformerException: com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: An invalid XML character (Unicode: 0x3) was found in the element content of the document.
could this be a problem of the characterset? but if, where to change what?
- we defined in ADMIN in 'report printing' / 'instance-settings': oracle-apex-listener
- we are working with apex-listener 2.0 (integrated in weblogic-server)
- we work with APEX 4.2.1.00.08
thanks for any ideas

When I look oracle doc : http://www.oracle.com/technology/products/database/application_express/html/configure_printing.html)
prerequisites for installing WAR file (Installing and Configuring Apache FOP) imply downlad for Oracle Containers for J2EE (10.1.3.2) ,

the accessed page seems restricted to Oracle Application Server 10g Software Downloads.
My question : is the last Version (10.1.3.5.0 : Oracle Containers for J2EE 10g (OC4J) (build #090727, 91 MB) - J2EE 1.4 compatible with EJB 3.0 / JPA 1.0 support ) also VALID for Oracle 11g ?

Cannot print PDF using Apex Listener

Hey folks,
We're having some issues trying to print reports as PDF's using the latest version of Apex Listener. For some reason, every PDF that is created that we try to open gives an error, saying that it's either not a PDF file or that it's corrupted somehow. We're using Apex 4.2 and for the time being, just the default table layout that Apex provides when printing. I believe our instance of Apex Listener is at the very least connected properly because we can print Excel or RTF without any issues. We've double and triple checked all of our options so I'm very confused as to what is happening. If anyone has any input, I'd be very grateful.

Have had same problem with error message "Unable to convert postscript file". No response from Adobe. Even tried their technical support which said they offered no support for free products. Have found a couple go arounds but no fixes.

Hi,
I have a requirement to view the PDF content in the apex page region, I am using Apex 3.2 and Oracle 10 Enterprise edition.
I Uploaded the PDF file in the shared component under static file. Now i need to view the content of the PDF file.
Please suggest me method to view the PDF content.
I saw the link in denes blog here he shows how the PDF is getting displayed. but there is no steps of methods mentioned

Hi Sudhir,
when you look at page 3, region "pdf canvas" then you will see the code:
<canvas id="the-canvas" style="border:1px solid black"></canvas>

<script type="text/javascript" src="https://raw.github.com/mozilla/pdf.js/gh-pages/build/pdf.js"></script>
<script type="text/javascript">
    // NOTE:
    // Modifying the URL below to another server will likely *NOT* work. Because of browser
    // security restrictions, we have to use a file server with special headers
    // (CORS) - most servers don't support cross-origin browser requests.
    var url = '#WORKSPACE_IMAGES#Shilpa.pdf';
    // Disable workers to avoid yet another cross-origin issue (workers need the URL of
    // the script to be loaded, and dynamically loading a cross-origin script does
    // not work)
    PDFJS.disableWorker = true;
    // Asynchronous download PDF as an ArrayBuffer
    PDFJS.getDocument(url).then(function getPdfHelloWorld(pdf) {
      // Fetch the first page
      pdf.getPage(1).then(function getPageHelloWorld(page) {
        var scale = 1.5;
        var viewport = page.getViewport(scale);
        // Prepare canvas using PDF page dimensions
        var canvas = document.getElementById('the-canvas');
        var context = canvas.getContext('2d');
        canvas.height = viewport.height;
        canvas.width = viewport.width;
        // Render PDF page into canvas context
        page.render({canvasContext: context, viewport: viewport});
</script>
There you can change the url, I actually already reference your workspace file in there.
But please give a list of browsers you are trying to support. It all depends on the specifics.
Cheers,
Dietmar.

How to save pdf in APEX 3.0

is there a way to save the pdf output into APEX database in ver 3

Hi,
based on Marc's suggestion to use UTL_HTTP to get the PDF I played around a little bit. But I didn't try to directly communicate with the report server which would require to send and XML stream which I would have to generate, I took a shortcut and thought why shouldn't APEX do the hard work :-)
1) Create a table with a BLOG, eg.
CREATE TABLE TESTPDF (PDF_REPORT BLOB);2) Set the "Static ID" region property to a value.
3) Load the below procedure into your application schema
3) Call the procedure getPDF in one of your page processes.
CREATE OR REPLACE PROCEDURE getPDF
( pStaticRegionId IN VARCHAR2
IS
    vRegionId APEX_APPLICATION_PAGE_REGIONS.REGION_ID%TYPE;
    vReportURL VARCHAR2(255);
    vBlobRef   BLOB;
    vRequest   Utl_Http.req;
    vResponse Utl_Http.resp;
    vData      RAW(32767);
BEGIN
    -- get internal region id of the report region
    SELECT REGION_ID
      INTO vRegionId
      FROM APEX_APPLICATION_PAGE_REGIONS
     WHERE APPLICATION_ID = Apex_Application.g_flow_id
       AND PAGE_ID        = Apex_Application.g_step_id
       AND STATIC_ID      = pStaticRegionId
    -- build URL to call the report
    vReportURL := 'http://apex.oracle.com/pls/otn/f?p='||
                  Apex_Application.g_flow_id      ||':'||
                  Apex_Application.g_step_id      ||':'||
                  Apex_Application.g_instance     ||':'||
                  'FLOW_XMLP_OUTPUT_R'||vRegionId||'_en';
    -- get the blob reference
    INSERT INTO TESTPDF
      ( PDF_REPORT
    VALUES
      ( Empty_Blob()
    RETURNING PDF_REPORT INTO vBlobRef;
    -- get the pdf file from APEX by simulating a report call from the browser
    vRequest := Utl_Http.begin_request(vReportUrl);
    Utl_Http.set_header(vRequest, 'User-Agent', 'Mozilla/4.0');
    vResponse := Utl_Http.get_response(vRequest);
    LOOP
        BEGIN
            -- read the next junk of binary data
            Utl_Http.read_raw(vResponse, vData);
            -- append it to our blob for the pdf file
            Dbms_Lob.writeAppend
              ( lob_loc => vBlobRef
              , amount => Utl_Raw.length(vData)
              , buffer => vData
        EXCEPTION WHEN Utl_Http.END_OF_BODY THEN
            EXIT; -- exit loop
        END;
    END LOOP;
    Utl_Http.end_response(vResponse);
end getPDF;Haven't really be able to test the code with a real APEX report, because apex.oracle.com doesn't allow to load a page which references utl_http and I don't have access to another APEX instance right now. But I have tested that the utl_http code and the storage into the blob works with some other URL.
So if anybody could try out...
BTW, the above code should only be used as an example. I would suggest to pass the BLOB reference as parameter to the procedure and not do the insert directly in the procedure. That way you can use it for several different applications/tables.

Not Able to Print in PDF Format Apex

we are not able to print in pdf format with using a template, if we use default layout we are getting a pdf output,
Can any one please help me on this issue....
Thanks
Malleswar

Hello Malleswar,
we are not able to print in pdf format with using a template, if we use default layout we are getting a pdf output,If your scenario with APEX Listener is generally capable of producing a PDF when using a working template, than the error is very likely to be in your template, not in APEX Listener.
If that's the case, you'll probably find more people with experiences on how to build custom xsl-templates into your APEX application in the APEX forum: {forum:id=137}.
If you decide to post there (or even if you think it's better to continue here), please provide information on your APEX and APEX Listener version and whether you see some error information in APEX Listeners log when trying your own template or not. If you don't see anything there right now, enabling debug mode will make the log more verbose and probably provide a hint on which part of your template can't be processed properly by the FOP built into APEX Listener.

How to diagnose FOP to print PDF in apex?

I have configured the fop in linux.
I follow the steps outlined in http://www.oracle.com/technology/products/database/application_express/html/configure_printing.html
