Hi there i am currently trying to develope a java
stored procedure and place it in oracle and will try
to use that procedure to send a message to a server
but then it doesnt seems to work. is it possible?And what do you do with exceptions in your java proc?
I haven't ever done it myself, but I would be very surprised if it wasn't possible. I also wouldn't be surprised to find out that you have to configure various things to allow it in Oracle itself.

Using XMLType in a Java Stored Procedure

I have the following piece of java test code that attempts to read an XMLType object from the database. When I run this client side, using either the oci or thin driver it works fine. When I run the same code as a java stored procedure I get the exception shown below.
(The problem was first seen on 9.2.0.3/Win2K. Ive patched to 9.2.0.4 and am still getting the same error)
Can anybody please help?

Is it possible to use iFS API within java stored procedure?

question:
is it possible to use the iFS API for file handling
within a java stored procedure (which is invoced by a trigger)?
is there an "elegant" workaround if it is not possible?
problem:
my java code using the iFS API works fine outside
the java stored procedure
but invoked via trigger as java stored procedure
it throws following exception:
IFS-20102: Unable to start service (IfsDefault)
i am using:
oracle 9.0.1
oracle internet file system 9.0.1.1.0
windows 2000
thanks

thanks for your help
i looked through the applications developers guide
the basics behind advanced queueing (as far as i understand) is:
program A inserts a message into the queue - and program B gets message from the queue and processes it
question 1:
but what is the difference between advanced queuing and a queue i create by myself
(simply with a database table) and let application B (which runs in a loop)
check if the queue is filled
or am i missing something important which makes advanced queuing more practicable for my problem?
question 2:
you wrote about advanced queuing support in iFS 9.0.3, but the newest version i found was iFS 9.0.2
did you reffer to the advanced queuing mechanism in general or to a spezial queuing feature in iFS 9.0.3?
thanks

How to use OUT variables in my stored procedure

I'm wondering if I can get some help using OUT variables in my stored procedure. Here's my code...
CREATE OR REPLACE PROCEDURE testProj.testProcedure (
     v_segment_id IN VARCHAR2,
     v_student_id OUT VARCHAR2,
     v_current_code OUT NUMBER,
     v_new_code OUT NUMBER
) AS
BEGIN
     SELECT
          s.student_id,
          s.quad_code_id,
          nc.quad_code_id
     INTO
          v_student_id,
          v_current_quad_code,
          v_new_quad_code

     INNER JOIN testProj.new_codes nc ON s.student_id = nc.student_id
     WHERE s.segment_id = v_segment_id ;
END testProcedure ;
EXECUTE testProj.testProcedure ('44') ;
When I execute that stored procedure with the above execute statement, I get this error:

How to use a parameter passed to stored procedure in cursor?

I am rather new to Oracle stored procedures and I'm sure that
this is rather simple. Could someone tell me how to do the
following: I would like to pass the variable status into my
stored procedure and then use it in the where clause when
defining my cursor. I have the stored procedure working 100%
other than this small detail.
CREATE OR REPLACE PROCEDURE p_report_starwood_exhibita2(hno
VARCHAR2, cid INTEGER, kperiod INTEGER, status VARCHAR2, user
VARCHAR2) IS
BEGIN
DECLARE
     CURSOR bid_cursor IS
     SELECT bm.hotelid
     FROM dbo.bidmaster bm
     WHERE bm.channelid = cid
     and bm.contractperiod = kperiod
     and bm.bidstatus like '&status'
END;
Thank you

How to use dbms_Scheduler.Create_Job from within stored procedure?

Hello,
using 10g (10.1.0.2.0) on Windows 2000 I had problems to create scheduler jobs from within a stored procedure (see example below). What easily succeeds using anonymous blocks failed when calling from a stored procedure, due to ORA-27486. Only when I compile the procedure with invoker's rights the call to dbms_Job.Create_Job is successfull!? From my knowledge there is no difference between invoker's and definer's rights, if I compile and call with the same user, is there?
Does anyone know the reason for this behaviour or is it simply a bug?
Have a nice day.
BjÃ¶rn Hachmann

-- Example start.
create table t
a number(1),
b date default sysdate
create or replace procedure sched1
is
begin
dbms_scheduler.create_job(
job_name => 'TEST_JOB1',
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN insert into t values (1); END;',
repeat_interval => 'freq=secondly',
enabled => TRUE
commit;
end;
create or replace procedure sched2
authid current_user
is
begin
dbms_scheduler.create_job(
job_name => 'TEST_JOB2',
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN insert into t values (2); END;',
repeat_interval => 'freq=secondly',
enabled => TRUE
commit;
end;
exec sched1; -- This call fails with ORA-27486.
exec sched2; -- This call succeeds!
/* Cleanup.
exec dbms_scheduler.drop_job('TEST_JOB1', true);
exec dbms_scheduler.drop_job('TEST_JOB2', true);
drop table t;
*/

Your example code ran without problems for me on 10.1.0.3.0 so it probably is a bug.

"No Such File or Directory" in Oracle Java Stored Procedure

The following code:
import java.io.*;
public class CWoodTest {
public static String go(){
String result = null;
File file = null;
try{
file = new File( "/data/oracle/cwoodACH.test" );
FileWriter fileWriter = new FileWriter( file );
fileWriter.write("Working");
fileWriter.close();
} catch( IOException e ){
if( file != null)
result = e.getMessage() + " " + file.toString();
else
result = e.getMessage() + " file null";
if( result != null ) return result;
else return "Working";
is published to PL/SQL as
CREATE OR REPLACE PACKAGE CWoodTest AS
FUNCTION go
RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'CWoodTest.go() return java.lang.String';
END CWoodTest;
show errors
And the result is "No Such File or Directory", even though the user oracle owns /data/oracle and the user I'm logged in as has JAVAUSERPRIV and JAVASYSPRIV . I am able to use UTL_FILE from PL/SQL to write to /data/oracle, so I know that init.ora has the correct UTL_FILE_DIR settings (if this matters). Similar Java code works fine on my desktop. Ideas?
Thanks in advance

Did you grant execute rights on your FUNCTION go?
No better idea atm.

Can I use log4j with a java stored procedure

I have code that resides on the middle tier and on the database. Our company is using log4j for debugging purposes. In order to get my code to work on the database, I have had to remove all the log4j stuff. Has anyone tried to get code that has log4j messages to run on the database? I am not concerned with actual debugging, I just don't want to have to strip this code out if I can avoid it.

Hi Laura,
As far as I know, you have two choices:
1. Load the log4j classes into the database (using the "loadjava" tool).
2. Enable remote invocation of log4j classes via RMI (or similar).
Hope this helps.
Good Luck,
Avi.

How do we connect to a remote database from a Java Stored Procedure?

We have a situation where we are not able to use a PSP (PL/SQL server page) to update a remote database using database link in an Oracle8i database. This is a known bug on 8i and is fixed in 9i. Can this be done using PSP calling a Java stored procedure, which in turn connects to the remote database and performs the update. If so, how we do remote connectivity to another database from the current java stored procedure.

Java Stored Procedures + oralce.xdb.XMLType + initxdbj.sql

In order to use XMLType object in java stored procedures, I need to import oralce.xdb.XMLType package. I got compiler error saying "Class oracle.xdb.XMLType not found" (See List1).
I check my installed package, sure enough these is no "oracle/xdb/XMLType" or any xdb related one. (See list2) This surprises me since my 9i/Solaris installation was successful and spotless one.
The 9i App Dev - XML doc states that script $ORACLE_HOME/rdbms/admin/initxdbj.sql could install that package. (See List3) The fact is no way this script could be found from Oracle901/Solaris8 or Oracle901/NT installations.
If java program moved to client and included xdb_g.jar in CLASSPATH, then it is fine as Doc declares. It just failed to compile in server as stored procedures.
Please help, Thanks.

The oracle.xdb.XMLType is available in the xdb_g.jar file in the ORACLE_

Using oracle.xdb.XMLType inside JServer:
This class is pre-loaded in to the JServer and is available in the SYS schema.
It is not loaded however, if you have upgraded your database from an earlier
version. If you need to upload the class into the JServer, you would need to run the
initxdbj.sql file located in the ORACLE_HOME/rdbms/admin directory, while
connected as SYS.
Using oracle.xdb.XMLType on the client:
If you need to use the oracle.xdb.XMLType class on the client side, then ensure that
the xdb_g.jar file is listed in your CLASSPATH environment variable.

Java Stored Procedure with LOB as input parameter (oracle 9i 9.2.0.6)

Hi,
Is there a way to pass CLOB as input and output as part of java stored proceudre in oracle 9i (9.2.0.6)?
I have to perform some data conversion on the CLOB data in java program and return the converted CLOB as output.
--Ramesh Lokineni

The reason why I want to use java for conversion is because, I want to perform base64 encoding decoding on the content stored in CLOB column. I tried to use by chunking the data into smaller pieces and apply the base64 encoding, but when I decode the CLOB using base64, I am not getting the same data. Later when I read about how base64 encoding happens I realized chunking the data in CLOB doesn't work. That's when I started to diggin how I can pass CLOB to java stored procedures.
