Calling PL/SQL Functions And Open Oracle Reports From ADF Application

Hi all,
My company will convert some projects from Oracle forms to Oracle ADF so, we need to call the PL/SQL functions and open the Oracle Reports (which are already exist) from ADF Application.
Thank You..

How Do i Call An xml publissher and a jsper report from ADF pages

Hi All
How Do i Call An xml publissher and a jsper report from ADF pages

I used the above links to create XML's and from there a formatted report of data from the database. I accomplish this by connecting to the database inside the XMLPublisher.java file. I also have my query hard-coded inside the DataTemplate.xml to extract the info from the database. This limits my ability on what the user can accomplish with the system.
Is it possible to run my reports based on an iterator within Jdeveloper, as opposed to having to manually enter the query and connect to the database within the XMLPublisher.java file and the template.xml?
Thanks.

Calling oracle reports from java applications

Hi:
I was wondering if anyone can tell me how to invoke an oracle report from a java application.

yes it is possible. There is a cgi script called viewreport.cgi. Have the jsp page call it (GET or POST method) and place the user parameters inside the form.

Open OBIEE report from web application

Experts, I want to open OBIEE report from a web application. I have a question regarding the security here. Say I login as 'USER1' in web application, I would have to pass 'USER1' in nquser parameter. Correct? Also, this report has access to 'Sales Group' users only. So, does 'USER1' in web application need to be assigned to 'Sales Group'? Or, any user in the web application can open this report as long as I pass nquser in the GOURL.
thx,
parag

You don't need to specify group details.
When the report hits OBIEE, it will determine the permissions based on the nquser.
Hope it helps.

How to open new window and generate oracle report from apex

Hi,
I had created an application that generates PDF files using Oracle Reports, following this Guide.
http://www.oracle.com/technology/products/database/application_express/howtos/howto_integrate_oracle_reports.html
And I followed 'Advanced Technique', so that users can't generate PDF file by changing URL and parameters. This is done for security reasons.
But in this tutorial, when 'Go' button is pressed, the PDF file is displayed on the same window of apex application. If so, user might close the window by mistake. In order to avoid this, another window have to be opened.
So, I put this code in the BRANCH - URL Target. (Note that this is not in Optional URL Redirect in the button property, but the branch which is called by the button.)
javascript:popupURL('&REPORTS_URL.quotation&P2100_REP_JOB_ID.')
But if the button is pressed, I get this error.
ERR-1777: Page 2100 provided no page to branch to. Please report this error to your application administrator.
Restart Application
If I put the code 'javascritpt ....' in the Optional URL Redirect, another window opens successfully, but the Process to generate report job is not executed.
Does anyone know how to open new window from the Branch in this case?

G'day Shohei,
Try putting your javascript into your plsql process using the htp.p(); procedure.
For example, something along these lines should do it:
BEGIN
-- Your other process code goes here...
htp.p('<script type="javascript/text">');
htp.p('popupURL("&REPORTS_URL.quotation&P2100_REP_JOB_ID.")');
htp.p('</script>');
END;
What happens is the javascript is browser based whereas your plsql process is server based and so if you put the javascript into your button item Optional URL Redirect it is executed prior to getting to the page plsql process and therefore it will never execute the process. When you have it in your branch which normally follows the processes, control has been handed to the server and the javascript cannot be executed and so your page throws the error "Page 2100 provided no page to branch to"... By "seeding" the plsql process with the embedded javascript in the htp.p() procedure you can achieve the desired result. You could also have it as a separate process also as long as it is sequenced correctly to follow your other process.
HTH
Cheers,
Mike

Running Oracle Reports from JSF Application in Websphere Application Server

Hi everybody;
in our company we are developing jsf applications and we want to use our existing Oracle reports. Reports are deployed in Oracle Application Server 10G. Is there a way to call those reports from our jsf applications deployed in websphere application server.

Calling reports is just constructing and submitting a URL. So constuct the url in your jsf app or create static hyperlinks in your jsf app to go to the needed url. The url should look something like:
http ://hostname:7777/reports/rwservlet?report=myrep.jsp&userid=scott/tiger@dev10g&desformat=html&destype=cache

To find and open Crystal Reports using SI_Name & SI_PARENT_FOLDER

Hi,
I have been given the below properties and link, which uses Crystal Reports (I guess its using java integration)
http://<portal server>/projectsportal/jsp/collaboration/deliverables/pdf_report.jsp?entity=1&Entity_Type=P&Key_Indicators=Y&LV_FROM_FY=&LV_TO_FY=
The properties used are
CMSName = 138.220.5.56:6400
hostName= crystalprd
authentication = secEnterprise
#infoStoreQuery = SELECT * FROM CI_INFOOBJECTS WHERE ( SI_NAME = 'OrganizationReport' AND SI_PROGID = 'CrystalEnterprise.Report' AND SI_PARENT_FOLDER = 2000 )
infoStoreQuery = SELECT * FROM CI_INFOOBJECTS WHERE ( SI_NAME = 'scorecard' AND SI_PROGID = 'CrystalEnterprise.Report' )
I have to make few changes in the Crystal Reports.
Please help me in finding out the report. What is the location of the report ?
Thanks in Advance for your timely help.
Eswari.

You have most of the info already here. Just use Query Builder to pull back the rest of the object info and you'll have what you need. I'm not sure which report you want, but either can be achieved in much of the same way. You'll need to know the parent-child heirarchy for the folder structure to determine where this report sits. once you have this info, open the CR designer and open the report from the repository navigating the folder heirarchy you found.
1. Open "Query Builder" from the start | programs menu on the server. Depending on the version of XI you are using, the url will differ.
2. Execute a query similar to what you posted to bring back the info for the report object (not instances) with the name 'scorecard'. If multiple reports exist in different folders with the same name, they will all be returned.
SELECT * FROM CI_INFOOBJECTS WHERE SI_NAME = 'scorecard' AND SI_PROGID = 'CrystalEnterprise.Report' and SI_INSTANCE = 0
3. Look for SI_PARENT_FOLDER attribute and query on this ID next. That should give you the name of the parent folder the report sits within.
SELECT * FROM CI_INFOOBJECTS WHERE SI_ID = <si_parent_folder>
4. You will need to keep querying for the parent in order to work your way up the folder tree.

currently im doing this in adf form. from here how to transfer the information in adf form into offer letter template and print it in pdf?

Hi,
actually there are two questions in one:
1: How to call an Oracle Reports from ADF?
Answer is to use the Oracle Reports URL to request a report. The data submitted by an ADF form could be passed as URL parameters or - if sensitive information is involved - saved in a temporary table for reports to look it up. Have a look at for an option to download the PDF by referenring the Reports URL http://docs.oracle.com/cd/E23943_01/apirefs.1111/e12419/tagdoc/af_fileDownloadActionListener.html
2: How to generate PDF from ADF
Jasper Reports, BI Publisher or POI are the options people use for reporting in ADF. Jasper Reports and BI Publisher allow the creation of PDF documents based on form content submitted from ADF

Count number of rows from oracle and sql database and generate a report

Hi All,
Can someone help me in writing a java program for the following scenario?
1. Read the number of rows available from oracle table and print the total row count in a Report.txt text file.
2. Read the number of rows inserted in a sql database (after a specific process-just an information) and print the total row count in the same text file Report.txt .
3. Read the Error Log file (which is generated after a specific process say it has success and failed report for each iterations) and print the number of success and number of failure in the same text file Report.txt .
I need the final Report.txt file in the following format:
1. Oracle table <table name> has 500000 rows.
2. After completion of the specific process 300000 rows were added to SQL table <table name>
Error Log Report:
300000 successfull entries and 200000 failed entries were found from the Error Log file.

Thanks for your immediate reply.
I'm just a beginner in java so if i make any mistake please correct and excuse me. :)
This is the code i have for connecting to two different database.
package connectDatabase;
* @author
import java.sql.*;
public class ConnectTo
     public void OracleDB()
          Connection dbconn;
          try {
            DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
            String connString="jdbc:oracle:thin:@SYS_IP:1521:oracl";
            dbconn = DriverManager.getConnection(connString, "uname","pwd" );
        catch(SQLException sqlex)
             sqlex.printStackTrace();
        catch(Exception excp)
            excp.printStackTrace();
     public void SqlDB()
          Connection conn;
          try {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            String url = "jdbc:odbc:connectDB";
            conn = DriverManager.getConnection(url,"uname","pwd");
          catch (Exception e)
            System.err.println("An Exception occured! " +e.getMessage());
}I'm just codding the second half which is for connecting to oracle databse and calculates the row count and displayes in the command prompt.
then connects to SQL database and counts successfull insert in the table.(row count) and displayes on the command prompt.
can you simplify the above code so that i can call the oracleDB() method and SqlDB() method seperately from another calss file using the object of this class?
I'm ok if the report can be seen in a command prompt. FInally i need to calculate the success and failure count from the log file. will let you know once i'm done with codding.

Calling Oracle Reports from stored procedures

Hi ,
Can anybody tell me whether this is possible and if so, how it can be done. Thanks for your help.
Regards,
Deepa

Oracle Forms allows you to easily integrate Oracle Reports into your
applications. However, on the Macintosh, it is not possible to use
the normal Oracle Reports runtime to generate ASCII text files. In
order to allow ASCII text files to be generated with Oracle Reports
on the Macintosh, the Reports<TEXT> Runtime applications was
developed. This version of the runtime only allows you to generate
text files and should not be used for other purposes.
While the Reports<TEXT> Runtime application has been provided, there
is no built in integration with Forms. This bulletin explains a
method which you can use integrate these two applications with little
effort. In order to use this method, you will need the following
items installed on your computer:
* Oracle Forms 4.0
* Oracle Reports 2.0
* Oracle Command 1.0
* AppleScript 1.1. This is available as part of the Macintosh
Operating System version 7.5 as well as with certain 3rd party
applications.
Because the only way to use the Reports<TEXT> Runtime application is
through Oracle Command, we will be using Oracle Command to run the
Reports<TEXT> Runtime application. However, we need some way to
communicate with Oracle Command which report we would like to run and
what parameters we would like to pass in to Reports. To accomplish
this goal, an AppleScript application will be used. Forms can use
AppleEvents (Apple's method for inter-application communication) to
communicate with this AppleScript application which can then create
an Oracle Command script file to run. So, the summary of events
which will take place are as follows:
1. Forms dynamically creates a command line to run the
Reports<TEXT> Runtime application.
2. Using AppleEvents, Forms communicates this command line to the
AppleScript application which writes out an Oracle Command
script file.
3. The AppleScript application communicates with Oracle Command and
tells it to run the script which it just created.
4. Oracle Command runs the script which invokes the Reports<TEXT>
Runtime application.
1. Creating the AppleScript Application
The core of this solution is the AppleScript Application. While it
is not necessary for you to be familiar with AppleScript, it will
help tremendously in your understanding of how everything works.
Here we provide you with an AppleScript which provides the
functionality we need to implement our procedure.
Note: This AppleScript is designed to work with the Macintosh
Operating System version 7.5. It should work with earlier
versions of the Operating System, but no guarantees are
made. Furthermore, there are known problems with the version
of AppleScript provided with version 7.1.2 of the Operating
System which will cause your machine to crash when this
script is executed. These problems with AppleScript were
corrected for the version 7.5 release of the Operating System.
-- This AppleScript Application is responsible for being a
-- "go-between" between Oracle Forms and Oracle Command. It is
-- responsible for both dynamically creating Oracle Command script
-- files and disposing of these files.
-- NOTE: This AppleScript Application was written for the Macintosh
-- Operating System version 7.5. It has not been tested
-- on any other version of the Macintosh Operating
-- System.

-- The syntax "on <<...>> args" is how you setup an AppleScript to
-- accept AppleEvents.
-- Be careful, the << and >> characters are option-\ and option-|
-- respectively. They are not two less-than signs and two
-- greater-than signs.
on <<event R20Trunt>> cmdScript
-- First, let's construct a, hopefully, unique file name
set dt to ((current date) as string)
set hr to (word 5 of dt)
set mn to (word 6 of dt)
set sec to (word 7 of dt)
set fName to (hr * 3600 + mn * 60 + sec as string)
-- For this example, we will put all dynamically constructed
-- script files onto the desktop.
set tFold to (path to desktop)
set fName to (tFold & "tmp." & fName as string)
-- set up a mnemonic for the Return character
set cr to (ASCII character 13)
try
-- open our Oracle Command script file
-- The sequence <opt-l> at the end of the following line
-- should be type in as an option-l (that is, a lowercase L).
set fRef to (open for access file fName with write <opt-l>
permission)
-- Now, write the Oracle Command command line which was
-- passed to us via AppleEvents.
-- The sequence <opt-l> at the end of the following line
-- should be type in as an option-l (that is, a lowercase L).
write (cmdScript & cr) starting at <opt-l>
((get eof fRef) + 1) to fRef
-- Now we have to also ask Oracle Command to let us know
-- when it is finished with the script file we are
-- creating. Basically, we are asking Oracle Command to
-- use AppleEvents to let us know when to throw away the
-- file we are creating
-- The sequence <opt-l> at the end of the following lines
-- should be type in as an option-l (that is, a lowercase L).
write ("host SENDAE aplt R20T remv ---- t \"" & fName <opt-l>
& "\";" as string) starting at <opt-l>
((get eof fRef) + 1) to fRef
-- close the Oracle Command script file
close access fRef
-- Now that we have setup the temporary file,
-- tell Oracle Command to execute it.
tell application "Oracle Command 1.0"
runscript fName
end tell
-- You can put some error handling here if you'd like.
end try
end <<event R20Trunt>>
-- This is the AppleEvent handler to clean up when we are done. It
-- simply throws the temp file into the trash can.
-- Be careful, the << and >> characters are option-\ and option-|
-- respectively. They are not two less-than signs and two
-- greater-than signs.
on <<event R20Tremv>> fName
tell application "Finder"
move (fName as alias) to (path to trash)
end tell
end <<event R20Tremv>>
2. Setting Up Forms
It is useful to setup a PL/SQL Program Unit to hide the details
behind running the Text Runtime. Here is a suggested PL/SQL Program
Unit for you to use:
-- The following procedure is used to hide some of the details in
-- using the AppleScript Application. It accepts 4 arguments:
-- * The report name
-- * The name of the output file
-- * The parameters you would like to pass in. These need to be
-- formatted just as if you were calling reports from a
-- command line.
-- * A connect string for Reports<TEXT> Runtime to connect with.
procedure run_text_report (
rName in char,
oName in char,
params in char,
cString in char) is
cLine varchar2(1000);
begin
cLine := 'execute r20text module='| |rname;
cLine := cLine | | ' userid='| |cString;
cLine := cLine | | ' paramform=no batch=yes';
cLine := cLine | | ' destype=file desname='| |oname;
cLine := cLine | | ' desformat=dflt.prt '| |params| |';';
host('SENDAE aplt R20T runt ---- t "'| |cLine| |'"');
-- NOTE: in the above host() command, the series of quotes at the
-- end reads as follows: double-quote, single-quote, vertical
-- bar, vertical bar, the word cLine, vertical bar, vertical
-- bar, single-quote, double-quote, single-quote.
end;
Here is an example of how I can use the above procedure. In a
WHEN-BUTTON-PRESSED trigger, I might have:
declare
reportName varchar2(16);
outputName varchar2(64);
paramVals varchar2(64);
connectStr varchar2(16);
begin
-- We want to run the report named "myreport". The output from this
-- report should go into a file named "output.txt" located in the
-- "Reports" directory on my hard drive. This report accepts two
-- parameters: p_start_date and p_end_date. The connect string for
-- the database I am using is simply "scott/tiger"
-- Setup some variables to hold all the information I want to pass
-- in to run_text_report(). This information is put into variables
-- for readability.
reportName := 'myreport';
outputName := 'HD:Reports:output.txt';
paramVals := 'p_start_date=''01-MAR-95'' p_end_date=''31-MAR-95''';
connectStr := 'scott/tiger';
-- Run the report
run_text_report(reportName, outputName, paramVals, connectStr);
end;
3. Putting the pieces together
In order for this solution to function, you need to make sure that
both your AppleScript application and Oracle Command are running when
you make a call to run_text_report(). It is possible for you to
launch Oracle Command from within Oracle Forms with the following
line of code:
host('LAUNCHID oBTL');
If you place the above line of code in a WHEN-NEW-FORM trigger, you
can assure that Oracle Command will be running when your form is
launched.
It is also possible for you to have Oracle Forms launch your
AppleScript application. However, in order for you to do this, you
need to be very familiar with the Macintosh Operating System, how to
change the creator type of a file, and know what effects that change
can produce. If you do not know how to change the creator type of
your AppleScript application or are not comfortable doing so, you
should simply document that your users need to make sure to launch
your AppleScript application before trying to use your Form.
However, if you know how to change the creator type of your
AppleScript application and are comfortable doing so, here are the
steps you will need to take to have Oracle Forms launch your
AppleScript application for you:
* Change the creator type of your AppleScript application to
something unique.
* Modify the run_text_report() procedure. You need to change the
four character sequence "aplt" found in the host() command to the
new creator type of your AppleScript application.
* Add the line host('LAUNCHID <your new creator type>'); to your
WHEN-NEW-FORM trigger or to whichever trigger you placed the
host('LAUNCHID oBTL'); statement.
There is one significant difference between RUN_PRODUCT and this
solution. With RUN_PRODUCT, you have the option of specifying
whether or not the call should be synchronous or asynchronous.
However, the call to run_text_report() will always be asynchronous.
