Apex_util.get_print_document returns empty blob

Hi,
I'm trying to convert a xsl-fo template into PDF. I have the following code:
begin
declare
v_retval blob;
v_data blob;
v_xls clob;
v_xml_dat clob;
begin
select page_template
into v_xls
from flows_030100.wwv_flow_report_layouts
where flow_id =101
and report_layout_name = 'vv';
v_xml_dat := to_clob('<data><row><dat1>fff</dat1></row></data>');
v_data := wwv_flow_utilities.clob_to_blob(v_xml_dat);
v_retval := apex_util.get_print_document (v_data,v_xls,'xsl-fo','pdf')
htp.p(dbms_lob.getlength(v_retval));
end;
end;
This returns 0 instead of some PDF document. I guess there is something wrong with my input, probably the XML data. Any thoughts?

Anyone?

APEX_UTIL.GET_PRINT_DOCUMENT always returning empty BLOB

Dear community,
I have a huge problem when using the function APEX_UTIL.GET_PRINT_DOCUMENT in a job or database procedure.
The following code runs perfectly when I integrate it in the APEX application directly e.g. using a button to execute it (of course I use an anonymous PL/SQL block in APEX itself). But when I run the same code as a procedure or job in the APEX database itself I always receive a mail with an empty PDF:
CREATE OR REPLACE PROCEDURE APEX_DRUG_SAFETY.CALL_MAIL
is
l_id number;
l_document BLOB;
BEGIN
wwv_flow_api.set_security_group_id;
l_document := APEX_UTIL.GET_PRINT_DOCUMENT
+(+
p_application_id=>'105',
p_report_query_name=>'TestReport',
p_report_layout_type=>'pdf',
p_document_format=>'pdf'
+);+
l_id := APEX_MAIL.SEND
+(+
p_to        => '[email protected]',
p_from      => '[email protected]',
p_subj      => 'sending PDF via print API',
p_body      => 'Please review the attachment.',
p_body_html => 'Please review the attachment.'
+);+
APEX_MAIL.ADD_ATTACHMENT
+(+
p_mail_id    => l_id,
p_attachment => l_document,
p_filename   => 'mydocument.pdf',
p_mime_type => 'application/pdf'
+);+
wwv_flow_mail.push_queue(
P_SMTP_HOSTNAME => 'DESMTP.TEST.COM',
P_SMTP_PORTNO => '25');
end;
The problem is that the function APEX_UTIL.GET_PRINT_DOCUMENT always returns an empty BLOB when executed outside of the APEX application. I found this issue in several other posts in this forum but I did not find a solution.
The mail transmission itself works perfectly. Also with an attachment if e.g. I use another BLOB already stored in the database for testing purposes. So it is not the mail transmission that causes the problem but the empty variable l_document that is still empty.
Thanks in advance for the help.

GET_PRINT_DOCUMENT returns empty PDF

I'm attempting to use the GET_PRINT_DOCUMENT API to create a pdf report and store it in a table. However, the api always returns an empty BLOB. The test report for the Report Query, 'testSQL', runs fine.
The 'After Submit' process is as follows:
DECLARE
v_pdf blob;
BEGIN
v_pdf := APEX_UTIL.GET_PRINT_DOCUMENT (p_application_id => 16228
,p_report_layout_name => 'testSQL'
,p_report_query_name => 'testLayout'
,p_report_layout_type => 'rtf'
,p_document_format => 'pdf');
INSERT INTO report_inbox(user_id, report_name,mime_type, report)
VALUES ('ddornan','TestPDF', 'application/pdf',v_pdf);
COMMIT;
END;

Hi David.
I am using the same syntax code block with success. The only things I can suggest are..
1) Double check the spelling and CaPiTaLiSaTiOn of your query name and template name.
2) You may want to conisder declaring your application ID as a variable like this...
v_app_id NUMBER(10) := NV('APP_ID'); Thus avoiding any deployment issues with hardcoded application ID's.
Aside from that, the syntax looks great.
I'd be happy to take a look at the application for you if you put it on APEX.oracle.com
I've got quite a bit of experience using this functionality and would be happy to share any knowledge I can.

Making apex_util.get_print_document return an error message

We are using apex_util.get_print_document in a process to run a report something like this:
declare
   l_report blob := null;
begin
    l_report := apex_util.get_print_document (
        p_application_id      => :APP_ID,
        p_report_query_name   => 'report_query_name',
        p_report_layout_name => 'report_layout_name',
        p_report_layout_type => 'rtf',
        p_document_format     => 'rtf'
   if l_report is not null and dbms_lob.getlength(l_report) > 0 then
      apex_application.g_print_success_message := 'Report Created.<br>';
      INSERT INTO reports (attachment, date_created, filename, mime_type)
      VALUES (l_report, sysdate, 'report.rtf', 'text/rtf' );
   else
      apex_application.g_print_success_message := '<span style="color:#CC0000">There was a problem creating the report.</span><br>';
   end if;
end;And this works well most of the time. The problem is, if the report fails for some reason, apex_util.get_print_document gives no information whatsoever as to what went wrong. Is there any way at all we can find out what the problem was?

APEX_UTIL.GET_PRINT_DOCUMENT not returning anything

I have a report query and have provided a layout to print it
I need to get the html generated from the report so that I can mail it.
As I could not get the generated file in the PL/SQL package written , for quick testing I started testing using a SQL stmt to check for the length of the LOB
select dbms_lob.getlength(APEX_UTIL.GET_PRINT_DOCUMENT (
p_application_id=>my_app_id,
p_report_query_name=>'name of qry',
p_report_layout_name=>'name of layout',
p_report_layout_type=>'rtf',
p_document_format=>'htm')) lob_size
from dual
I also tried by providing the p_print_server => null in addition to the parameters passed.
But the query returns NULL only.
The qry and layout are correct as the query when tested in the edit qry screen in APEX shows the output report in the format required (including html , PDF etc)
Any pointers ?
Thx

APEX_UTIL.GET_PRINT_DOCUMENT Error Unable to get the document

Hi,
   I am working on Oracle APEX 4.1 to send the report as an attachment through mail I am unable to get the document while calling the APEX_UTIL.get_print_document. I have created a report query and report template (rtf template) so as to send the report as an email attachment. The report works fine individually upon clicking of button so there is no issue in BI publisher configuration. I am sure there is something very trivial which I am missing out here. Any help will be appreciated.

Try removing the parameter p_print_server from the call. This will use your default print server which should already be configured to use the BI Publisher engine.

Apex_util.get_print_document results in "503-service unavailable"

I'm using APEX 4.2.0.3.00.08 with GlassFish 3.1.2.2 on an Oracle 10.2.0.5 database.
Recently I created a report-query together with a xsl-fo report-layout created in Altova Stylevision. I've enabled and configured print-options and when I press my application button, I'm perfectly capable of viewing and/or saving the pdf-version of my report.
Additionally I want to save my report as BLOB in the database, but when I try this using apex_util.get_print_document, all I get in my table is a html-page containing the message "503-service unavailable".
I used the following page as reference:
Creating High Fidelity PDF Reports with Oracle Application Express but apparently I'm missing something or doing something wrong......I truly hope there's someone out here to help me!!
Thanks in advance!

Hello Mike,
I've been trying to create an application on apex.oracle.com to reproduce the problem, but I can't seem to get it to work.
I've uploaded a very simple layout created in StylusStudio, a simple query on the EMP-table only containgin FIRST_NAME, LAST_NAME and EMAIL and when I add the layout to the query and press "Test report", it works fine.
When I run the report from my application, it only shows a pdf with a thick, horizontal lines, like it's showing only empty cell borders.
Meanwhile I found out that the APEX-listener keeps reporting similair errors, even when I use that same simple stylesheet (created with StylusStudio) on the EMP-table, even when the stylesheet does not contain any special characters at all. In stead of the message starting with INFO: Character decoding failed. Parameter [#x200B;</xsl:text> , it then ignores the complete xslt-stylesheet (the complete contents of the stylesheet is between the brackets, in stead of just the string containg the special chars).
To be honest I'm a little lost now. First my focus was on how to get rid of the special characters, but now it looks like, even when I might succeed in that, it doesn't even solve my problem.
Any idea why my application doesn't show me the same report I see when testing the report-query?
The application can be found here:
https://apex.oracle.com/pls/apex/htmldb/f?p=29586
The bottom region is an attempt to show the pdf with the highest id, but I think it does not show the actual pdf (http-404)
The source for that PL/SQL region is:
declare
src_ varchar2(256);
mime_ varchar(48);
id_   number;
begin
select max(id)
into id_
from report_archive;
    select mimetype
      into mime_
      from report_archive
     where id = id_;
    src_ := 'src="#OWNER#.download_doc?i_doc_id=' || id_ || '" ';
    htp.p('<div style="">');
    if instr(mime_,'pdf') > 0 then
      htp.p('<embed height="800" width="1200" name="statement" ');
    elsif instr(mime_,'excel') > 0 then
      htp.p('<embed height="800" width="1200" name="statement" ');
    else
      htp.p('<embed height="800" name="statement" ');
    end if;
    htp.p(src_);
    htp.p('type="' || mime_ || '" />');
    htp.p('</div>');
exception
   when no_data_found then
      null;
end;
I really hope we can solve this!!!!

Apex_util.get_print_document in sql developer

I have not been successful in getting apex_util.get_print_document to work in sql developer, the return value is always null and inserted into the table. Inside of APEX it works fine, so I figured I had to set workspace id, but that did not help. Heres the basic code.
declare
rpt_blob BLOB;
begin
wwv_flow_api.set_security_group_id(my ws id);
rpt_blob := APEX_UTIL.GET_PRINT_DOCUMENT (
p_application_id => 122,
p_report_query_name => 'NYARNG_unit',
p_report_layout_name => 'TEST',
p_report_layout_type => 'xsl-fo',
p_document_format => 'pdf',
p_print_server => null);
insert into report_archive_tbl values ('test'||sysdate||'.pdf','application/pdf',rpt_blob,sysdate,'tread');
end;

Try
wwv_flow_api.set_security_group_id;instead of wwv_flow_api.set_security_group_id(my ws id);

Call print apex_util.get_print_document() with page item values

Hi all
I ran into an issue that very frustrated as it sounds so simple.
I'm in Apex 3.1.
My database has table TAB_CLASSES, TAB_STUDENT
My application has page 1 with P1_SID is student_ID
I had an simple report query name Class_query, show all classes that a student attends
select * from TAB_CLASSES where SID = :P1_SID;
I also select option "include application and session information"
I had report template Class_template
In my application, I have a process tried to generate report list classes for all students.
l_report blob;
for x in (select * from TAB_STUDENT)
loop
:P1_SID := x.SID;
l_report := apex_util.get_print_document (
p_application_id => :APP_ID,
p_report_query_name => 'Class_query',
p_report_layout_name => 'Class_template',
p_report_layout_type => 'rtf',
p_document_format => 'pdf'
insert all the l_report into database with SID as a part of l_report name (*)
end loop;
After this, I got multiple of l_report blob in database, number of report is exactly number of student in the TAB_STUDENT table. The problem is that every report looks the same, and it got the information of only first student
I guessed it did not pass the item value (P1_SID) every time it call the get_print_document, but it still shows in the report name (*)
Please help me. Thanks for any idea.

Thanks for the post of Marc, about how variables are binding and calling by process, I changed my app design to have a sp to print and store the pdf file. Then in my app, I just called the sp and passed the P1_SID. It worked.

Apex_util.get_print_document not generating correct output

hello,
Basically what I've done is this.
1) stored a very simple xml file in a clob field called xml_file_clob in a table called xml_test1
2) stored an rtf file in a clob field called rtf_layout in a table called xml_test1
3) created a procedure (below) called generate_report_as_blob which attempts to combine the xml and layout and generate a PDF from it which is stored into a blob field in the same table where 1) and 2) are above .....
4) I have confirmed that taking the clobs in 1) and 2) from the table above and creating xml and rtf files on my desktop that I can open the rtf file in Word, load the xml file and preview it and it does render the pdf as intended (so I think my clobs in the table are good)
5) run the procedure below. It compiles and runs with no errors but generates a file into the blob column that when downloaded to my desktop looks like the below output (when opening w/ pdf it says there was an error opening the file)
Any thoughts are greatly appreciated. I feel like I'm really close and am excited about what I could do with this if this can work.
Thanks in advance, KW

I have the same problem exactly...works as an APEX proc, will not work from sqlplus despite setting security group id. Mail works. Attachments with another BLOB works. But I can't get this function to give me the BLOB.

Apex_util.get_print_document

All,
below is a procedure (test_send_attachment1) that I cannot get to work and I've run out of ideas.
The value of xml_file_clob is detailed below and the rtf file spec is also provided. With these things, someone could, I believe, reproduce the problem.
I don't receive any errors and I do receive an email with a pdf attached. The problem is the pdf is 'malformed'
I should add that if I save the query that was used to generate this xml and upload to APEX the rtf file that I provided here and I test the report, it runs fine. Also, when I use the add-in to create the rtf with the below xml file and view the pdf, it processes just fine as well. So I think the "pieces" are correct.
I am using Oracle BI Publisher Template Builder for Word 10.1.3.4.1 (Build 130)
Thanks for having a look. I posted this here (even though it's related to BI Publisher) because I feel like the problem is with APEX_UTIL.get_print_document .... If the administrators feel this is better posted in another forum, let me know.
Regards.

Anyone?

Apex_util.get_print_document with bind

All,
I'm trying to create a process to bulk print a report to the file system using the API apex_util.get_print_document. Is there a way to pass bind variables to the report query when using this API? If not, has anyone come up w/another solution on mass printing reports that have parms?
Thanks,
Paul

Hi Paul,
APEX_UTIL API consists of 4 different GET_PRINT_DOCUMENT Functions based on parameters types(Function Overloading) that are being passed. If you look at the function where CLOB is the data type for parameter p_report_data, the bind variables can be passed to the SQL which willl be used by DBMS_XMLGEN or other XML/CLOB generation API's.
I have used DBMS_XMLGEN to generate the CLOB data which intern used by GET_PRINT_DOCUMENT function.

EntryProcessor invokeAll returning empty ConverterMap{}

Hi All,
I am trying to write a custom entryprocessor and whatever I return from the invokeAll method in the entryprocessor, I am always getting a empty ConverterMap{}. The code for the entryprocessor is as below:
public class CustomEP implements PortableObject, EntryProcessor {
     public CustomEP (){
public Map processAll(Set entries) {
          Map results=new HashMap ();
results.put ("1", "1");
System.out.println("Inside process All method");
          return results;
public Object process(Entry arg0) {
          Map results=new HashMap ();
results.put ("1", "1");
System.out.println("Inside process method");
          return results;
The client code to invoke this entryprocessor is as below:
Map results=cache.invokeAll(AlwaysFilter.INSTANCE, new CustomEP());
The processAll method on the Coherence nodes is invoked but if the print the results on the client side it return empty ConverterMap{}
On the other hand, if I invoke process method of CustomEP as below:
Map results=(Map) cache.invoke(AlwaysFilter.INSTANCE, new CustomEP());
I get the desired results. Please help me with the details why it is happening this way when the return type of the processAll is a Map.
Thanks a lot!
Regards,
S

Hi Robert and JK,
Thank you for your reply and time!
I could not find these details in any of the documentation that specifies keys passed in the result should be subset of the keys passed to the processAll method. Anyways, my problem is to invoke server-side code (avoid de-serialization) by passing a filter and then create a entirely new map (key and value will be different from the entries extracted from the passed filter) by reading the data from the passed entries. How can I implement it?
I am thinking to use aggregator as they are read-only and faster but again how to implement it using:
public Object aggregate(Set entries){
Again, I am getting an empty Map so is it necessary that the object returned should have keys matching the set of the entries passed to this method.
Secondly, there are other methods such as, finalizeResult() and init() if I extend AbstractAggregator, do I need to implement them and if yes, how? The entries set passed to the aggregate() method may not reside on the same node.
Please advise!
Regards,
SHi S,
the process() return value object, or the entry value objects in the map returned by processAll() can be arbitrary objects. So you just return a map from process(), and return a map as the entry value in the result map from processAll().
The AbstractAggregator has a fairly badly documented contract in the Javadoc (does not properly cover the values received in different scenarios for invocation). You should probably read the section about it in the Coherence book, that explains leveraging AbstractAggregator in significantly more details. It also happens to be in the sample chapter, but I recommend reading the entire book.
I am not sure about the issues relating to posting links to PDFs on Packt's webpage, so I won't do that. Please go to Packt's webpage (http://www.packtpub.com ), look for the Coherence book there and download the sample chapter (or order the book).
In short, all 3 to-be-implemented methods (init(), process(), finalizeResult()) in AbstractAggregator are called both on the server and on the caller side. You can distinguish which side you are on from looking at both the passed in fFinal boolean parameter and the m_fParallel attribute tof the aggregator instance.
There are 3 cases:
- non-parallel aggregation processing extracted values (m_fParallel is false, I don't remember what fFinal is in this case),
- parallel aggregation storage side processing extracted values (if I correctly remember, m_fParallel is true, fFinal is false),
- parallel aggregation caller side processing parallel results (m_fParallel and fFinal are both true).
Depending on which side you are on, the process method takes different object types (on server side it receievs the extracted value, on caller side it receives a parallel result object instance).
You SHOULD NOT override any of the other methods (e.g. aggregate() which you mentioned).
The advantage of this approach is that the AbstractAggregator subclass instance can pass itself off as a parallel-aggregator instance.
You should put together a temporary result in a member attribute of the AbstractAggregator subclass, which also means that it will likely not be thread-safe, but at the moment it is not necessary for it to be thread-safe either as it is called only on a single-thread.
Best regards,
Robert
