Calling java program from PL/SQL

I already have a java program that encrypts/decrypts data.
How can I use or rather call this program in PL/SQL?

Please refer [url http://download-west.oracle.com/docs/cd/B19306_01/appdev.102/b14261/subprograms.htm#sthref1814]Calling External Subprograms on PL/SQL User's Guide and Reference.

Calling java program from PL/SQL code

Dear,
How to develop and call a java program from PL/SQL code?
What about if this program will call other java programs?

Perhaps the Java Developer's Guide would be a good place to start

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.

Error while calling java program from ABAP

Hi Experts,
We are trying for RFC inbound scenario.
We followed the below blog
/people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
We are working with SAP JCO 3.0.2
We are getting the error : 'STFC_CONNECTION' could not be found in the server repository.
After I run the Java server program if I execute the RFC destination directly from SM 59 it is showing successful messages.
If I stop the java program then this RFC is failing. Based on this we concluded that RFC to Java connection is working fine.
But as mentioned in blog if we call the RFC Destination from ABAP program it is giving the below error,
'STFC_CONNECTION' could not be found in the server repository.
If we test the RFC destination using RFC_TRUSTED_CHECK standard FM we are getting the below error.
'RFCPING' could not be found in the server repository.
We create the RFC destination of Type : TCP/IP as exactly mention in the blog.
Please help us in resolving this issue.
Thanks
Prince

Pabi,
Using the RFC connection,we can establish a link between Java and SAP.
Afterwards,hope we can call Java program from ABAP.
Below is the sample piece of code to establish RFC connection(link) between Java and SAP.

      RESPTEXT LIKE SY-LISEL,
      ECHOTEXT LIKE SY-LISEL.

CALL FUNCTION 'STFC_CONNECTION'
   DESTINATION RFCDEST

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

Can I call a Java program from a SQL Server Trigger?

Hello,
I want to encrypt some data in a database column in SQL Server. Today I am using java code to encrypt the value and store it in the database using JDBC.
Now I want to use a VB client to store the encrypted value in the SQL Server DB. Since the encryption is handled by a java class, can I write a trigger in SQL Server that while inserting the raw data, calls the java class for encrypting the value and then inserts the encrypted value into the column?
In general, is it possible to call a java class from a SQL Server trigger?
Thanks
Bipin

Here are 3 examples of code for insert, update and delete:
CREATE TRIGGER [PLI_INSERT_TRIGGER] ON [dbo].[PLI]
FOR INSERT
AS
Declare @cmd sysname, @code sysname, @list sysname
     Select @code = PLI_K_COD, @list = PLI_K_LISTINO from inserted
     Set @cmd = 'java mirrorDb.Copy PLI INSERT ' + @code + ' ' + @list
     EXEC master..xp_cmdshell @cmd
CREATE TRIGGER [PLI_UPDATE_TRIGGER] ON [dbo].[PLI]
FOR UPDATE
AS
Declare @cmd sysname, @code sysname, @list sysname
     Select @code = PLI_K_COD, @list = PLI_K_LISTINO from inserted
     Set @cmd = 'java mirrorDb.Copy PLI UPDATE ' + @code + ' ' + @list
     EXEC master..xp_cmdshell @cmd
CREATE TRIGGER [PLI_DELETE_TRIGGER] ON [dbo].[PLI]
FOR DELETE
AS
Declare @cmd sysname, @code sysname, @list sysname
     Select @code = PLI_K_COD, @list = PLI_K_LISTINO from deleted
     Set @cmd = 'java mirrorDb.Copy PLI DELETE ' + @code + ' ' + @list
     EXEC master..xp_cmdshell @cmd
you must go "sql server entreprise manager" right click on the table you want to add triggers and select: all activities, manage triggers.
You have 3 examples: for an insert, for an update and for a delete
ON [dbo].[PLI] specify the table on which you want to setup trigger.
FOR DELETE, INSERT, UPDATE specify the event.
The Declare statement create the variables in which I want to put some values to pass to the java program, for example which table, which event, which key fields.
the "Select @code = PLI_K_COD, @list = PLI_K_LISTINO from inserted" set the variables with the value of the columns of the table I am interested to read from my java program, for example the variable @code receive the value of the column pli_k_kod (is the key) of the table PLI.
The "Set @cmd = 'java mirrorDb.Copy PLI DELETE ' + @code + ' ' + @list " prepared the variable @cmd with the java command followed by the package.classname and parameters.
The EXEC launch the command to the operating system.

Calling Cobol program from PL/SQL

What is the caling convention for PL/SQL to call a Cobol program?

You cannot do it directly from PL/SQL. PL/SQL is.. well, kind of abstract ito the actual platform it runs on. PL/SQL cannot talk directly to operating system. It cannot (itself) do socket calls, file I/O calls, use the printer, etc.
<p>
All this has to be done using a lower level implementation library - like UTL_FILE for example that wraps internal C written modules that does file I/O. PL/SQL can call these to do I/O on its behalf. Ditto for wrappers like UTL_TCP and others.
<p>
There is no default wrapper for calling external processes from PL/SQL. It can however be done indirectly using the external procedure (EXTPROC) feature, or using Java to do it.
<p>
The latter is the easiest. You create a Java stored proc that can access the operating system and run external programs and commands. You punch a big hole in the Oracle Java security to allow this Java stored proc access to the operating system. Next you create a PL/SQL wrapper for this Java proc which then in turn can be called from PL/SQL.
Just remember that you MUST secure this hole you've punched into Oracle security. If any Oracle user can access this PL/SQL wrapper, they can hack, compromise, trash or simply destroy your entire Oracle account on that server.
Here is the basic code:
create or replace and compile Java Source named "OSCommand" as

--                      (note that \n is used as separators in the string)
--                      returncode=-1   Java RTS error occurred (e.g. command does not exist)
--                      returncode=255 o/s command failed (e.g. invalid command params)

Call Java Program from ABAP Program

Dear all,
In our scenario, we need to let ABAP call services provided by a standalone Java program. From online help I found some overview introduction and I'd make the called program a registered program in a RFC with type "T" (TCP/IP Connection). Can anybody give some concrete documentation? A step-by-step guide would be greatly appreciated.
Best Regards
Jerome

Can i call java program from VC++ code...... Urgent!

hi,
I have VC++ code.
I want to run java program from VC++ (SDK).
Can I call it?
plz help it's urgent....
thanks in advance...

We do it all the time using the JNI invocation API (this is actually how the java.exe application works).
Here's a tutorial I just found (not sure how good it is, but it should get you going):
http://www.inonit.com/cygwin/jni/invocationApi/
One note: If you are going to be invoking the JVM from different threads in your native app, there is some special handling you will have to do - the above tutorial doesn't address this scenario (a dig through the JNI docs should help with that one, though).
Cheers,

Calling external program from PL/SQL

Does anyone know whether it's possible to call an external program living outside of Oracle from PL/SQl eg. a from a stored procedure?
Specifically i want to call back into my java appserver (ejb server) when a trigger/stored proc. is executed.
The call does not have to be synchronous, some sort of queue will do - eg JMS??
Any help greatly appreciated.

Hi
Which version of oracle you are using.
If it 8i, you can use external procedures/libraries. REfer to ORacle PLSQL documentation.
If you are using Oracle 7+ you can use dbms pipes to post your command string and a cron job to read the pipe and execute the string.
An alternate ugly way is to write to a file and some process reading the file at a regular interval.

How to call java class from pl/sql procedure ?

Hello everyone,
My query is..
There is one pl/sql stored procedure which is doing some business logic and storing data in some columns of one table, suppose the table name is 'ABC' .. and the rest of columns of table ABC are getting updated using java class. Now my problem is whenever I insert data in ABC using store proc.. i have to call that java class so that it will update the rest columns ( why java class for updating the columns in ABC is ..because that logic cant be done from pl/sql proc.. it has to be done using java )
and the other thing is.. oracle is in one machine and java is in another .. :(
hope ..u can help me out !!
Thank in advance !!

but that updation have to be done from java code only.. we are using GIS tools .. have to create some shape files and update the column with that shape file.. so creation of shape file has to be done from java code only..
so how to call java class file which is on another machine and oracle in another..
