Oracle-reports of generated pdf-report on a BLOB storage

Hey ppl,

I have this requirement:

I essentially generate a report of Jdev using a remote servlet call to reports of the oracle, which generates the PDF for me very carefully and store it locally. The problem is immediately put this on the DB as a BLOB once the report is generated. I know how to store the pdf as a BLOB on the DB. I know how to make the call to oracle-reports and generate my pdf. What I don't know, first is sequentially generate the local pdf report and that which was generated once continue to store it on my DB.

I want it to be done in the context of a single request. As in the entire process must be completed by a cycle. I don't want to keep some kind of end of day procedure that inserts in the comics at the end of the day.

As soon as the report was requested by the user, I want the PDF (which is generated by the reports) will also be stored on the DB.

My problem (which I'm sorry has been repeated already 2wice above) is that I have basically lose control once redirected through the servlet to the call of the report. There is no way I can load Jdev, side reports, that the pdf was generated and now must be kept on the Pb, because I lost the session context by redirecting to a different servlet.

Any help would be GREATLY appreciated.

See you soon

Hello

its a while I ago one looked at Oracle reports, however, I think that the mechanism of the event is quite complex to achieve

I want it to be done in the context of a single request.

Which means that if reports Oracle locks, the user session follows.

As in the entire process must be completed by a cycle.

Unfortunately, you can't control how long reports run, which means that there is no sense in the judgment of the lifecycle of page for this

I don't want to keep some kind of end of day procedure that inserts in the comics at the end of the day.

Very well, but I remember there is a complete riding contest in reports which would allow you to have the report server Oracle trigger download

So, I think, the architecture, so that I would go is:

-user request report
-report generates PDF output
-reports will be mailed to DB
-reports_processing table contains the Userid and reports ID more Pavilion update when report is done
-If you use JSF, you can use af:poll to check frequently that the report is finished.

  • Oracle reports launch report via a url specify file name

    Hello to you all,.

    We are launching reports using url, open them in pdf format in our browser.
    for example.
    http://ACC-Rapp/reports/rwservlet?A100-RACC & Server = RACC rep_A100 & Report = a100_daily_order. Rep & destype = cache & desformat = PDF

    now, when you try to save the generated pdf file a file name is automatically proposed in your backup as "name of file" box.

    Can manipulate us the proposed file name?

    now the proposed name is like:
    http://ACC-Rapp/reports/rwservlet?A100-RACC & Server = RACC rep_A100 & Report = a100_daily_order. Rep & destype = cache & desformat = PDF.pdf
    OR

    (
    I know we can (must) specify a file name if we choose to save the pdf file generated in the file [DESTYPE = desformat = desname=c:\mydir\myxml.pdf PDF file]
    but this isn't what we want to do here. We just want to manipulate the file name suggested when a user decides to save the file

  • What is the problem with my Oracle reports parameter?

    Hello

    We use a PL SQL package that allows the user to select the report you want Oracle and associated parameters.   While the control is passed to Oracle 11 g reports.

    The requirement of one of the reports is to enable more detailed codes be selected by the user and then shown.  The detailed code is an alphanumeric field that can hold between 4 and 6 characters.

    If my data model looks like this

    SELECT student_id

        FROM my_view

       WHERE detail_code IN :p_detail_code;

    and the parameter that I'm passing to Oracle reports looks like this (when I view the source HTML code)

    & p_detail_code =('1001','1002')

    so no record is selected.

    However, if my data model looks like this, I get the records you want:

    SELECT student_id

      FROM my_view

    WHERE detail_code IN ('1001', '1002');

    We have Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production.

    Please tell me what is the problem with my setting.  Thanks a lot for your help.

    This isn't how you can use in. See this example on how to solve it with the digital settings. If your setting is a character, you need to change this.

    In fact, when you simply enter 1,2,3 as an input parameter, you actually create this query:

    Select *.

    from my_table

    where num_column in ("1,2,3")

    Use rather a lexical parameter:

    Select *.

    from my_table

    & p_where

    In the parameter after relaxation shape, build the lexical like this:

    :p_where := 'where num_column in ('||:p_param||')';

  • How to display different text for the labels in group above report Oracle report

    Hello

    Is there a way to change the text that is displayed in the labels in a report over the Group? For example, I have a report above group with my columns of data and above the columns, I have my column labels, but I would like to be able to display various text, i.e. different labels according to requirement. In other words, Column1 label could say column 1 or it's Column1, based on a condition. This is Oracle Report Builder 10.1.2.0.2.
    Thank you.

    If you use the wizard the column headers are created as fixed text elements. No way to change that.
    So, you have to delete text and replace by fields that use some of the columns in your data as the source model. This is how I create reports all the time. There is never any fixed text, all the text is retrieved in the data model.

    You can also use the format trigger. Simply place the elements of different text on top of the other and return TRUE or FALSE to display the correct label.

    Yes! You can. But you will need to provide some information at least during the validation of any question.
    What are you the version of your report?

    in general, select data showing the field and press F11 to go code editor and you will see

    ........
    begin
    return (true);
    end;
    

    Write here your condition and display and hide it. Ditto for the labels. For example
