Hibernate sql-update calling in Java

Hi,
In Hibernate, how to call native <sql-update> in java , since there is no "name" attribute associated with it? Any examples are really appreciated.
In Customer.hbm.xml
<class ...>
<sql-insert>
insert into customer
(cust_id, firstname, lastname, age, address, city)
values (?, ?, ?, ?, ?, ?)
</sql-insert>
</class>
Please provide an opinion on this.
Thanks

Thanks Rolls, I went through the link before. But there they haven't mentioned that how the insert or update native SQL will be invoked from java side. I assume that the SQL queries will be called implicitly when we set the values for the DO (persistent instance) and save it using the session.save() , For eg,
Customer customer = new Customer();
customer.setCustId(100);
customer.firstName("Bob");
session.save(customer)
But when I do that I am getting the below error in PostgreSQL 10.0:-
org.postgresql.util.PSQLException: The column index is out of range: 4, number of columns: 3
Please clarify.

Out of memory error when calling a java stored procedure multiple times

Trying to run a PL/SQL loop calling a java stored procedure, I get the following error:
"ORA-04030: out of process memory when trying to allocate 262188 byte callheap,ioc_allocate free)"
(with some other error lines).
The stored procedure does two major things:
1) Open a socket to communicate with a server, of which it queries some data.
2) Use JDBC (with the default DB connection it has, as a stored procedure) to write the results to a table.
All socket connections, statements, etc. are properly closed and all memory should be garbage collected between each call.
Can anyone offer an explanation or additional checks to make? I'm quite sure the code isn't causing the problem, since I've tried running it as a stand alone application (outside of Oracle) and didn't have any problems.
Thanks.

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.

How to call a PL/SQL procedure from a Java class?

Hi,
I am new to the E-BusinessSuite and I want to develop a Portal with Java Portlets which display and write data from some E-Business databases (e.g. Customer Relationship Management or Human Resource). These data have been defined in the TCA (Trading Community Architecture) data model. I can access this data with PL/SQL API's. The next problem is how to get the data in the Java class. So, how do you call a PL/SQL procedure from a Java program?
Can anyone let me know how to solve that problem?
Thanks in advance,
Chang Si Chou

Have a look at this example:
final ApplicationModule am = panelBinding.getApplicationModule();
try
     final CallableStatement stmt = ((DBTransaction)am.getTransaction()).
                                                                                     createCallableStatement("{? = call some_pck.some_function(?, ?)}", 10);
     stmt.registerOutParameter(1, OracleTypes.VARCHAR);
     stmt.setInt(2, ((oracle.jbo.domain.Number)key.getAttribute(0)).intValue());
     stmt.setString(3, "Test");
     stmt.execute();
     stmt.close();
     return stmt.getString(1);
catch (Exception ex)
     panelBinding.reportException(ex);
     return null;
}Hope This Helps

PL/SQL Procedure Calling Java Host Command Problem

This is my first post to this forum so I hope I have chosen the correct one for my problem. I have copied a java procedure to call Unix OS commands from within a PL/SQL procedure. This java works well for some OS commands (Eg ls -la) however it fails when I call others (eg env). Can anyone please give me some help or pointers?
The java is owned by sys and it looks like this
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "ExecCmd" AS
//ExecCmd.java
import java.io.*;
import java.util.*;
//import java.util.ArrayList;
public class ExecCmd {
static public String[] runCommand(String cmd)
throws IOException {
// set up list to capture command output lines
ArrayList list = new ArrayList();
// start command running
System.out.println("OS Command is: "+cmd);
Process proc = Runtime.getRuntime().exec(cmd);
// get command's output stream and
// put a buffered reader input stream on it
InputStream istr = proc.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(istr));
// read output lines from command
String str;
while ((str = br.readLine()) != null)
list.add(str);
// wait for command to terminate
try {
proc.waitFor();
catch (InterruptedException e) {
System.err.println("process was interrupted");
// check its exit value
if (proc.exitValue() != 0)
System.err.println("exit value was non-zero: "+proc.exitValue());
// close stream
br.close();
// return list of strings to caller
return (String[])list.toArray(new String[0]);
public static void main(String args[]) throws IOException {
try {
// run a command
String outlist[] = runCommand(args[0]);
for (int i = 0; i < outlist.length; i++)
System.out.println(outlist);
catch (IOException e) {
System.err.println(e);
The PL/SQL looks like so:
CREATE or REPLACE PROCEDURE RunExecCmd(Command IN STRING) AS

I have granted the following permissions to a user who wishes to run the code:
drop public synonym RunExecCmd

Kamal,
Thanks for that. I have tried to use getErrorStream and it does give me more info. It appears that some of the commands cannot be found. I suspected that this was the case but I am not sure about how this can be as they all appear to reside in the same directory with the same permissions.
What is more confusing is output like so:

Calling a Java Class from PL/SQL

Hai,
I need a technique of calling a class file and invoke its
methods written in Java by PL/SQL for my intranet development.
PLease let me know if you have really experienced and won.
Thanks
JOhnson

First, to call a Java class from PL/SQL the class needs to be
deployed to the database. you can check the 8i documentation for
the instructions for loading Java into the database(LoadJava).
The document contains information on how to load the Java and
call it from PL/SQL. The following links should help.
Loading Java:

Calling a Java Function from PL/SQL

Hi,
I would like to call a Java API from a java class residing on the middle tier ($OA_JAVA)
from the subscription code of a business event. The business event will have a
subscription with java rule function as my Java API. And the business event will be
raised from PL/SQL code using WF_EVENT.RAISE API. I want the Java API to
executed SYNCHRONOUSLY without deferring the event. Can you please provide
pointers to this.

Calling a Java Store Procedure from PL\SQL

I have this code in pl/sql

RETURN VARCHAR2
AS
LANGUAGE JAVA
NAME 'JAVA_SCHEMA_VALIDATOR.validation(java.lang.String, java.sql.Blob) return java.lang.String';
And when i'm calling it i'm getting the following error:
ORA-00932: inconsistent datatypes: expected an IN argument at position 2 that is an instance of an Oracle type convertible to an instance of a user defined Java class got an exception while converting to the user class
I had this code working in another database user, but in the new user i get this error. There's something i have to do for the conversation BLOB-> java.sql.Blob run without a problem?

Antonio,
Are you sure you didn't use oracle.sql.BLOB instead of java.sql.Blob?

A proper designed application in the database tier is far more scalable and performs better than using a separate middle tier for the application.
This should be self evident.
A middle tier requires more moving parts between the application and data. There now sits a network pipe between application and data. There are more software layers that slows down the interaction of the application with the data - more stuff that can go wrong. More stuff that needs to be maintained and configured and secured.
What's more, the database tier is a lot more scalable than the middle tier. Oracle Real Application Clusters. Oracle Parallel Processing. Oracle Shared Server. Etc.
These are robust and mature technologies.
One major fact that seems to be missed by so-called IS architects favouring a middle tier is that the middle tier cannot make a single database query or transaction go faster.
Scaling the middle tier is done by throwing more hardware at it. But not a single additional mid-tier h/w platform will make the database tier any faster. Will make the database tier scale.
Then there is also the issue of costs. A middle tier requires additional hardware. It requires support and maintenance agreements with the vendors. It requires middle tier software to be purchased. It requires a new set of skills to do middle tier development. It deals with different technology and different programming languages.
Why? How can this approach be sensible when:
- Oracle scales exceedingly well (and this scalability is not dependent on more h/w purchasing)
- Oracle deals with a single programming language (PL/SQL)
- Oracle supports high availability
- Oracle supports redudancy
- Oracle supports the complete application tier inside the database
If you have problems now leveraging Oracle (as an application tier), then you will have more problems when doing it a middle layer. Why?
Because the lack of experience/skill/knowledge required to make Oracle work for you, is not now suddenly negated and not needed when moving the application tier to Java.

Can we call a Java Stored Proc from a PL/SQL stored Proc?

Hello!
Do you know how to call a Java Stored Proc from a PL/SQL stored Proc? is it possible? Could you give me an exemple?
If yes, in that java stored proc, can we do a call to an EJB running in a remote iAS ?
Thank you!

For the java stored proc called from pl/sql, the example above that uses dynamic sql should word :
CREATE OR REPLACE PACKAGE MyPackage AS
TYPE Ref_Cursor_t IS REF CURSOR;
FUNCTION get_good_ids RETURN VARCHAR2 ;
FUNCTION get_plsql_table_A RETURN Ref_Cursor_t;
END MyPackage;
CREATE OR REPLACE PACKAGE BODY MyPackage AS
FUNCTION get_good_ids RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'MyServer.getGoodIds() return java.lang.String';
FUNCTION get_plsql_table_A RETURN Ref_Cursor_t
IS table_cursor Ref_Cursor_t;
good_ids VARCHAR2(100);
BEGIN
good_ids := get_good_ids();
OPEN table_cursor FOR 'SELECT id, name FROM TableA WHERE id IN ( ' | | good_ids | | ')';
RETURN table_cursor;
END;
END MyPackage;
public class MyServer{
public static String getGoodIds() throws SQLException {
return "1, 3, 6 ";

I want to call External Java class from the PL/SQL

Hi,
I am using Oracle Apps R11i (11.5.7), I wanted to call external Java class from the PL/SQL. This external Java class is residing in another application server.
How do I do this.
I know one way. Develop C routine in Oracle Apps to call external java class and call this C routine from the PL/SQL.
Is there any simple method available? or any other method?
Thanks in advance.
-Venkat

First of all, this is a Java application you're talking about, right (i.e. it has a main() function)? It's not just a class that you're trying to instantiate is it? If it's an application, you obviously have to start a new virtual machine to run it (rather than using the virtual machine built into the database like stored java). I'm a little leary of your mention of an "application server" as this would more commonly mean that a virtual machine is already over there running with access to this class. In which case, you'd typically interface with SOAP or some other RPC API.
All that aside, as long as you have physical disc access (through NFS or whatever) to the class file, you could use a java wrapper class with a system call to do this. In fact, there is a thread in just the last day or so on this very forum that has the code to do just that (see " Invoking OS Commands from PL/SQL"). However, it's worth noting that the virtual machine will be running on the database server in this case and not the application server.

Calling PL/SQL function from external Java class

I was wondering if I was able to call a pl/sql function from an external java class? If so, would you be able to tell me briefly on how to go about it. I know I can call java methods that are internally stored in the db from pl/sql, but I was hoping I could call pl/sql from external java. Thanks,
Kelly

Ok, I made the changes, but I'm now getting the following error:
Error code = 1403
Error message = ORA-01403: no data found
ORA-06512: at "IOBOARD.GETSTATUS", line 6
ORA-06512: at line 1
The ora-01403 I don't understand because there is data for the name Kelly.Brace.
ora-06512 error: at string line string.
Here's what the code looks like after I made the changes:
String sql = "{?=call ioboard.GetStatus(?)}";
      // create a Statement object
      myStatement = myConnection.prepareCall( sql );
      myStatement.setString( 1, "Kelly.Brace" );
      myStatement.registerOutParameter(2, java.sql.Types.LONGVARCHAR );
      // create a ResultSet object, and populate it with the
      // result of a SELECT statement
      ResultSet myResultSet = myStatement.executeQuery();
      // retrieve the row from the ResultSet using the
      // next() method
      myResultSet.next();
      // retrieve the user from the row in the ResultSet using the
      // getString() method
      String status = myResultSet.getString(1);
      System.out.println("Hello Kelly, your status is: " + status);
      // close this ResultSet object using the close() method
      myResultSet.close();Here's what the function looks like:
CREATE OR REPLACE FUNCTION GetStatus( user_name in varchar2)
RETURN VARCHAR2
is
v_status varchar2(10);
BEGIN
select iob_location into v_status
from ioboard.iob_user
where iob_username = user_name;
RETURN( v_status);
END;This works perfectly in the SQL Window:
select iob_location
from ioboard.iob_user
where iob_username = 'Kelly.Brace';

Calling pl/sql api through multiple java threads

Hi All,
I need to call a pl/sql api from multiple java threads simultaneously and all thread will use same db connection.
I want to know if all the threads will simultaneously call the pl/sql api then will the local variable inside pl/sql procedure be shared between them or they will get separate instances of variables.
TIA

You cannot make multiple parallel client calls over the same Oracle session handle. There is a single non-threaded/non-fibre serialised server process servicing client requests for that session. (physical process on Linux/Unix, thread in the oracle.exe process on Windows).
Each thread on the client side, needs its very own Oracle session. Thus each thread will have a server process footprint on the server. Which could be problematic if 10 clients each starts 10 threads - as it means a 100 processes on the server are needed to service these client threads.
Have a look at Overview of OCI Multithreaded Development in the Oracle® Call Interface Programmer's Guide for how to use the threading call interface of the OCI - as oppose to rolling your own where each thread manually needs to deal with is OCI session context.

Spring/Hibernate tier called from Java Stored Procedure

Here is my scenario.
Building out a new physical model alongside an old db.
Two schema's inside same Oracle instance.
We are building a new Java tier on top of the new schema using spring/hibernate.
To maintain sync with the old db we are building a load of PLSQL code that will be called by PLSQL stored procs on the old schema.
====
Now it occurred to me that if I could put a copy of my new java tier in the database itself then the trigger code on the old schema could call a java stored proc wrapper which in turn called into my new java tier inside the instance.
This way I avoid duplication business logic in the db sync and the java middle tier. Basically I do away with the PLSQL sync code and just use the new java component.
This clearly has advantages from an automated testing point of view too.
So very interested in how/if anyone has made this work.
Potential issues...
- JVM version (outside the db we use Sun Java 5 - inside the db I'm not sure what is used).
- How would spring access it's config files?

user563578,
You asked:

You also asked:
Potential issues...
- JVM version (outside db use Sun Java 5 - inside db not sure)
- How would spring access it's config files?
Oracle has its own JVM embedded in the database: OJVM
In Oracle 8i it is compatible with JDK 1.2
In Oracle 9i it is comaptible with JDK 1.3
In Oracle 10g it is compatible with JDK 1.4
You can access files outside of the database from OJVM, you just need to set correct permissions.
Perhaps Kuassi Mensah's book, Oracle Database Programming Using Java and Web Services will be of help?
Good Luck,
