Calling Java screens from Oracle Forms application

I am working with a client that has a large Oracle forms application. Since rewriting the entire application in Java is not an option at this time, the strategic direction is that any new modules that are to be created for the application are to be done in Java and called from the Forms menu. The decision as to what tool to use to develop the Java modules is still under debate. What is the best (most seamless) way to do this...calling a Java screen from a Forms application? If anyone has any experience in this, or can direct me to some literature on it, it would be greatly appreciated. Thanks.

This is a web app in Forms/Reports 10g R2 running off Oracle AS and an Oracle db. The challenge for us is that the direction is that any new enhancements (screens) are to be built using Java (in either ADF Faces or Swing, another point for debate later) and then called from the Forms app. The business client is only paying for the enhancement. They don't care about moving off Forms to Java, so any extra work on the part of IT to do this, has to be fairly minimal and doable within the project budget. The movement to Java is an IT direction. Is there a way to do this without having to build a java framework for the entire Forms application (which I assume would take some time and involve retesting the entire app)?

Calling Java programs from Oracle Stored Procedure

Is it possible to call Java programs from Oracle stored procs? If possible Can this be used to exchange data from other applications? Is there a better method/feature in oracle for doing data exchange with other apps?

If what you mean by Oracle stored procedures is pl/sql then yes.
You can create a "wrapper" this way:
CREATE OR REPLACE FUNCTION xmlXform
in_mapUrl IN VARCHAR2,
in_inputUrl IN VARCHAR2
RETURN VARCHAR2
AS
LANGUAGE JAVA NAME
'com.yourcompany.xml2any.xform(java.lang.String,java.lang.String)
RETURN java.lang.String';
Then load the java as:
loadjava -user youruser/youruserpasswd -resolve -verbose lib/xmlparserv2.jar classes/com/yourcompany/xform.class classes/com/yourcompany/xml2any.class
The java, given the correct permissions, can do anything java can do including communicate with outside applications.
Is this the "best" way... depends on what you are trying to accomplish.

Please provide codes with details showing step by step.

hi
try something like this.
DECLARE
charWinHandle VARCHAR2(50);
numWinHandle NUMBER;
BEGIN Set_Application_Property(Cursor_Style,'BUSY');
charWinHandle := Get_Item_Property('Control.Rep',Window_Handle);
numWinHandle := To_Number(charWinHandle);
:Item('Control.CrystalReport1').OCX.Crystal.Crysta lReport.WindowParentHandle
:= numWinHandle;

:Item('CONTROL.CRYSTALREPORT1').OCX.Crystal.Crysta lReport.Connect
:= 'DSN=;UID=' || Get_Application_Property(UserName) ||
';pwd=' || Get_Application_Property(password) || ';dsq=;';
Crystal_CrystalCtrl.ReportFileName( :Item('Control.CrystalReport1').interface,
'C:\Sample_Rep.Rpt' );
Set_Window_Property( Forms_Mdi_Window, Window_State,Maximize );
Set_Window_Property( 'MAIN', Window_State, Maximize );
:reptitle := 'Report Preview Window';
numWinHandle := Crystal_CrystalCtrl.PrintReport( :Item('Control.CrystalReport1').interface );
Set_Application_Property(Cursor_Style,'DEFAULT');
END;NOTE: Change the report name and path according to your required file name and path in
the "Crystal_CrystalCtrl.ReportFileName" method call. Also, the connection string shown
assumes that you will use the current USER and PASSWORD for the Form.
- To make the above Form generic so that you can run any Crystal report from it, then create
a parameter for the report name and pass it to the Form using CALL_FORM from any other Form.
Then just replace the file name with the passed parameter.
-. Run the Form
If its correct/helpful please mark it thanks.

Calling web service from oracle forms 10g

Problem Description:
I'm following the steps as per the doc:
http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html
to create a java stub to call external web service and then use java importer in oracle forms to call this web service from oracle forms.
WSDL for external web service used is http://gend:83/DesignService.svc?wsdl
The service was developed by us.
Calling the web service using JDeveloper works fine but when I complie in Oracle Forms it returns wrong number of types of arguments in call SENDHELLO.
The code from oracle form to call web service is as below:
DECLARE
jo ora_java.jobject;
xo ora_java.jobject;
rv varchar2(2000);
ex ora_java.jobject;
str varchar2(100);
BEGIN
jo := GendServiceClient.new;
rv := GendServiceClient.sendHello('Nora');
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.toString(ex));
END;
Any help/ideas on this is greatly appreciated. Thanks.

My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
I use UTL_HTTP.BEGIN_REQUEST to call a URL then load I load the data to a table as a CLOB since we have more than 4000 characters. Now I need to parse the XML and load it into a form. I have never done this so if there is a helpful site please let me know. I have looked at several sites but none do what I want.
Thanks

Calling web service from oracle forms fails with ORA_JAVA.JAVA_ERROR

Yes, it is the message line - so basically this call fails => rv:= CurrencyConvertorStub.ConversionRate(jo,'CAD','USD'); and control goes in the exception block

Calling Crystal Reports from Oracle Forms 10G

Hi everyone,
I am trying to call a crystal report from Oracle Forms 10G.
I have a button on my Form which when clicked calls a Crystal Report which the uaser then wants to save as a PDf file.
Can someone please send me the code to do this and also the exact steps that are to be followed.
Thanks
Fm.

Hi Andreas,
I am trying to call the crystal report from an Oracle Form using a URL. No batch file is being used here.
I am looking for a peice of code similar to run_product or run_report built in in Oracle which calls an Oracle report from an Oracle Form.
Also I dont want to display the report on a screen or a window in Oracle Forms. I would like it to run just as we run an Oracle Report from an Oracle Form.
Is that possible ? If yes please let me know the steps to do this.
Thanks

Calling Sql*Loader from oracle Form builder

How do i call sql* loader from my forms to import the external data in different formats into my existing database?
Specify the flexibility of sql* loader to import external data from .txt files or .xls files.
Would be thankful if certain examples are given along with the answer.

Hi,
1. First you have to create seperate ctl (Control files) which maps to different file formats
2. Using Oracle Forms,
2a) You can use the 'HOST' command to execute the command line ie. In this case executing
SQL*Loader script
2b) You also have the feature in ORACLE forms to read text files and load the data into
ORACLE db.
This can be achieved by using TEXT_IO package which comes with ORACLE Forms.
Hope this helps

Call Oreacle report from Oracle form

Hi,
I need call a Oracle report from Oracle Form and found the the following procedure from this forum. I have 2 parameters 'start_date' and 'end_date' passing to called report. The following example just have onle parameter
'departmentno' passing. Is that mean I need to call add_parameter twice like the following?
add_parameter(plid, ''start_date' , TEXT_PARAMETER,:control.start_date);
add_parameter(plid, ''end_date' , TEXT_PARAMETER,:control.end_date);
In the following example:
add_parameter(plid, 'departmentno', TEXT_PARAMETER,to_char(:dept.deptno));
Thanks for clarification!!

Call Java function from multithreaded VC++ application

Friends, I want to call Java function from two threads of a single VC++ application. I can call it from single thread but when I call it from another thread also, JNI_CreateJavaVM() replies with an error.

Your posting is ambiguous. My impression is that you have two threads, both trying to create a java VM?

Calling third party java page from Oracle form

Hi,
Is it possible to call a third party java (html+java) form page (residing in separate web service server) which would take input from standard Oracle form (OCO) page?
The third party page would validate the fields sent by form page and then will provide the results which should be copied back into standard oracle OCO form page.
Regards,
Aneesh

Don't know if you can do this from Forms PL/SQL, but you should be able to write a stored procedure in the database that does it for you. The stored procedure could use the database package UTL_HTTP to make the HTTP request and receive the response.
Your custom stored procedure can be called from Forms PL/SQL. If you are caling to a tru web service, you can also look at the UTL_DBWS package which is a bit more high level for calling a web service, than the raw UTL_HTTP package.
