Re Java Stored Procedure Problem

Ben
There appear to be some problem with the forum. It doesn't want to show my response to your post with the subject "Java Stored Procedure Problem". See the answer to this thread for an example of how to do this...
Is there a SAX parser with PL/SQL??

DBMS_JOB on Java Stored Procedure problem

Hi all,
(running on Oracle 9i : 9.2.0.7.0 64bit on HP/UX)
I have a Java Stored procedure that reads a table
One of the fields in this table is a CLOB containing some more SQL.
We then executeQuery() that SQL (and e-mail the output).
(Obviously I also have PL/SQL wrapper around it, which we'll call PROCNAME).
For certain pieces of SQL, this second executeQuery() fails throwing ORA-00942, but only when run from a DBMS_JOB(!).
Calling "CALL PROCNAME('argument')" from sqlplus/toad works fine, but setting "PROCNAME('argument')" to run as a DBMS Job fails on some SQL with the above error. (All as the same username).
java.lang.StackTraceElement doesn't seem to exist in Oracle java, so the only error I have to go on is e.getMessage() from SQLExecption which returns:
ORA-00942: table or view does not exist
Any help at this strangeness would be appreciated!

Hi Cris:
May be is a problem of the effective user which is running the procedure.
Which is the auth_id directive at the PLSQL call spec?
Look at this example procedure UploadNews for example:
http://dbprism.cvs.sourceforge.net/dbprism/cms-2.1/db/cmsPlSqlCode.sql?revision=1.21&view=markup
this procedure calls to the cmsNews.doImport which is implemented as Java Stored Procedure.
Also check if your loadjava operation is not using -definer flag.
Best regards, Marcelo.

Java stored procedure problem(oracle db)

HI,
we have a java stored procedure with the following definition, and that works as we want it to:
CREATE OR REPLACE FUNCTION processBulletin(in_varchar VARCHAR2) RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'JavaParser.Bufr_Ingest.processBulletin(java.lang.String) return java.lang.String';
And the Java portion:
public static String processBulletin(String in_bull)
... do something with in_bull
The problem is that we've recently discovered that the 32767 size restiriction on the input parameter varchar2 is too small. I don't want to rewrite the entire Java procedure. I figured the simplest (or at least temporary)solution would be to have the Java procedure accept a CLOB, convert that clob to a string and continue as it would. I was hoping someone might be able to tell me if the following would be possible:
CREATE OR REPLACE FUNCTION processBulletin(in_clob CLOB) RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'JavaParser.Bufr_Ingest.processBulletin(oracle.sql.CLOB) return java.lang.String';
And the Java portion:
public static String processBulletin(oracle.sql.CLOB in_clob)
String in_bull = clob_in.getSubString(1, (int)clob_in.length());
... do something with in_bull
Thanks

I don't know about Java stored procedures, but in JDBC you usually use streams to work with CLOBS. Here's Oracle JDBC Developers Guide, Working with LOBs

Java Stored Procedure Problem

Hi all,
I was able to deploy the Java class into the database (the message says Success). And then I am able to desc MyJavaSproc name in SQL*Plus and see the Pl/SQL parameter and return types. But when I use either call or select from dual, it tells me the the Java class (MyJavaName) is not there. The Oracle error is this: ORA-29540: class MyJavaName does not exist. I am running 10gR2. I did encounter a problem when I first tried to deploy using J2SE 1.5 as source and target and JDev suggested that I change that to an earlier version. I changed that to 1.4 and then deployed successfully.
Could someone help me with this? Thanks a lot.
Ben

Thanks. I created a simple file Java class with JDev (10g 1.3). I have some static methods (according to Oracle docs) in the class. Then by following JDev's help doc, I created a deployment profile for the project using JDec. I then added the Java methods that I wanted to deploy as sprocs. As I said, after I changed the J2SE from 1.5 (the default) to 1.4, the deployment was successful. I can see it using desc in SQL*Plus. I can also see it in the database connection tab in JDev. I can open the class stub created by JDev, and the sprocs and funcs are listed under Functions and Procedures on the database connection tab.
Thanks.

Transformation to WORD from XSLT with java stored procedure - PROBLEM

Hi all,
I'm building a java function for transformation of xml document through .xslt scheme to WORD. I use xalan.
Now, everything works fine if I run the java function on the client VM
But on the server where the classes needed for the transformation are loaded, it crashes with a strange exception
nulljava.lang.NullPointerException
Now I've located the problem, and it occurs in this line in the java code:
transformer.transform( new StreamSource(xmlFile), new StreamResult(osIzlez));
(where xmlFile is the source for the transformation, and the transformer is configured with the proper .xslt scheme, osIzlez points to a bytearraystream of a blob in the database where the .doc file is going to be generated and loaded)
I also found out that the NullPointerException occurs because the transformer is actually null on the server (although it's configured with the .xstl scheme and should not be null ! ), but on the client it's never null!
What could be the problem, does anyone have an IDEA?
Edited by: Daniel Kiprijanovski on 17.9.2009 03:07

OK, i found out that there's a reported bug about that exception on the java VM. I found a way arround it however.
Thanks,
Daniel K.

EJB calling Java Stored Procedure / Problem sending mail

Hi,
This exception usualy occurs when the handlers haven't been imported in your application.
Please check whether you have imported following in your source code.
import javax.mail.*;
import javax.mail.internet.*;
Also make sure that you have loaded " latest " mail.jar and activation.jar into the database.

Problem of java stored procedure

hi,
now I use the oracle9i JDeveloper9.0.3.1 to develop java stored procedure and then publish it to oracle9i database.
In the database I create PL/SQL procedure to invoke the java stored procedure.But I encounter the problem,that is ,when I run the PL/SQL procedure ,it throw the java.lang.NullPointerException ,while the java class,the java stored procedure can run correctly invoked by the main class of java.The code of the java stored procedure is as follows:
import java.sql.*;
import java.util.Properties;
public class SQLServerEventDistribute
public static void sqlServerSaveData(String hostName,String databaseName,String user,String password,String tableName,int x1,int y1,int x2,int y2,String ip)
String url="",sql="",userName="",passwd="";
Connection connection;
Statement statement;
url="jdbc:microsoft:sqlserver://"+hostName+":1433;DatabaseName="+databaseName+";User="+user+";Password="+password;
sql="INSERT INTO "+tableName+" VALUES("+x1+","+y1+","+x2+","+y2+",'"+ip+"')";
Properties property=new Properties();
property.setProperty(userName,user);
property.setProperty(passwd,password);
try
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
// DriverManager.registerDriver(new com.microsoft.jdbc.sqlserver.SQLServerDriver());
connection=DriverManager.getConnection(url,property);
statement=connection.createStatement();
statement.execute(sql);
}catch(ClassNotFoundException connectSQLServerEx)
System.out.println(connectSQLServerEx.getMessage());
catch(SQLException connectSQLServerEx)
System.out.println(connectSQLServerEx.getMessage()+connectSQLServerEx.getErrorCode());
the main class is as follows:
public class Test
public static void main(String[] args)
SQLServerEventDistribute.sqlServerSaveData("gsm","gsmd","sa","sa","IPBinding",11,45,24,21,"23.1.248.12");
and the PL/SQL procedure is as follows:
PROCEDURE TEST AS
BEGIN
SQLSERVERSAVEDATA('gsm','gsmd','sa','sa','IPBinding',11,45,24,21,'23.1.248.22');
END;
How can I deal with it?
can you tell me?
thanks

Hi JavaQQ,
This is just a guess, but I think you need to load the
Micro$oft SQLServer JDBC driver into the Oracle
database (using the "loadjava" utility).
In any case, there are several ways -- apart from JDBC
-- for accessing a different database from within an
Oracle database. Have you tried searching the Oracle
Web sites for suitable products?
Hope this helps.
Good Luck,
Avi.abramia ,thank you very much.
but I have load the Microsoft SQLServer JDBC driver into the Oracle database .
When I debugged the PL/SQL procedure,the exception was thrown at line connection=DriverManager.getConnection(url,property);
What's the problem with it?

Problem passing REF CURSOR to JAVA STORED PROCEDURE

Hi,
I've written a small Java class with a static method and
imported that into Oracle 8i. The method expects a
java.sql.ResultSet object as parameter. According to the
documentation of Oracle, a REF CURSOR (cursor variable) maps to
java.sql.ResultSet in JDBC.
The definition of the Java Stored Procedure was accepted without
problems:
CREATE OR REPLACE PROCEDURE RESULTSETPASSINGTESTPROC (row
WASTypes.GenericCurType)
as language java
name 'sqlj.ResultSetPassingTest.testResultSetPassing
(java.sql.ResultSet)';
WASTypes is a package containing the definition of the generic
cursor:
CREATE OR REPLACE PACKAGE WASTYPES
is
TYPE GenericCurType IS REF CURSOR;
END WASTypes;
In a function I'm opening the cursor via
'Open cursorVariable for sqlStatement';
Then this cursor variable is passed to the java method and the
error ORA-03113 is shown.
I tried to solve the problem by changing the type of the
parameter to oracle.sql.REF without success.
Does anybody know what wents wrong?
Thanks in advance.
Jan

Java Stored Procedure Deployment Problem with JDev 3.1.1.2

Dear JDeveloper Team:
I am having a problem deploying a test Java stored procedure to the database. In the Deployment Profile Wizard Connection tab, it displays no connection in the connection dropdown even though I have defined some connections that have been sucessfully connected to the database.
Please help.
Thanks,
Tom

Tom,
Verify that your Connections are valid as follows:
Double Click on the Connections folder of JDeveloper Navigator.
This opens up the Connection Manager.
Make sure you have defined JDBC Connections.
Pick your connection of intrest and select Edit... and then press the Test button to test the conneciton.
If this is a valid JDBC connection, then it should appear later when you run the deployment wizard.

Problem in running a java stored procedure&optimum settings for this needed

hi
we are using java stored procedures to read huge data from database tables and transfer them to another system.
the procedure is running fine but it fails after transferring 60000 records, the execution of procedure here does not terminate but keeps running with out performing any data transfer....since it does not give any error it is difficult for us to know what the actual problem is !!!!!!
i have checked the code many a time and i dont see any infinite loops in that code.
please give any pointers on why this might be happening?
please also give all the parameters which need to be taken care of while running a java stored procedure
thanks

I had a similar issue, the reason for that was picking the incorrect partner link.
Make sure the name of the selected partner link in the invoke output variable is matching with the Assign, in you case lets say you mapped the
Invoke
output variable is invoke_1_CallStoredProcedure_OutputVariable ( not nvoke_1_CallStoredProcedure_OutputVariable_1)
From
<Invoke_1_CallStoredProcedure_OutputVariable>
<LF_STATUS>
To
P_lf_status ( variable)
most of the time multiple variables are created when we try to select the output variable s in the Invoke.

Problem with static vars of SQLJ java stored procedure

Hi,
When I'm calling a PL/SQL stored procedure that call a Java stored procedure from another Java stored procedure, the second call to the Java stored procedure does not see the first Java stored procedure static variables.
Why is that?
Can I configure it to work otherwise so all the Java stored procedure calls in this session will share the same static variables?
Thanks

Hi:
Remove your ; at the end of the sql string.
String sql = "SELECT VERSION_OFA FROM XX_PARAMETERS";
I don't know why JDev accept the ; at the end of string in a prepare statement but AFAIK its not legal.
If your are using the SQL pane of JDev may be the tool strip the ; for you.
Best regards, Marcelo.

Problems with java stored procedure.

I have a java stored procedure that uses a package called RmiJdbc
which allows calling remote JDBC data sources from any java capable
machine.
I've loaded the RmiJdbc classes into oracle via the loadjava
command and everything seems to come up valid.
The stored procedure does a Class.forName() to get the driver
registered, than attempts to connect to the remote RMI driver.
The particular line it dies on is this (see the error below):
c = DriverManager.getConnection("jdbc:rmi:" + rmiHost + "/" + url);
A mangled version of this (minus the Oracle specific stuff) works
from the command line correctly. Can somebody point me in a
direction to figure out what's going on here?
THanks,
Eric

Performance problem with java stored procedure

hi,
i developped a java class, then I stored it in Oracle 8.1.7.
This class contains several import of other classes stored in the database.
It works, but the execution perfomances are disappointing. It's very long. I guess, that's because of the great number of classes to load that are necessary for my class execution.
I tried to increase the size of the java pool (I parameter 70 Mo in the java_pool_size parameter of the init.ora), but the performance is not much better.
Has anyone an idea to increase the performance of this execution of my class ?
In particular, is there a way to keep permanently in memory the java objects used by my class ?
Thanks in advance

before running Java, the database session needs to be Java enabled; this might be the reason why it is taking so long. If this is the case, you should see an improvement in subsequent calls, once a database session is Java enabled, other users can benefit from it.

I have some performance issue with java stored procedure. Hope some one will be able to help me out. I'm using java stored procedures in my application and basically these procedures are used to do some validation and form the XML message of the database tables. I have noticed that when I call the PL/SQL wrapper function, it is taking time to load the java class and once the class is loaded the execution is faster. Most of the time is spent for loading the class rather than executing the function. if I reduce the class load time, I can improve the performance drastically. Do any one of you know how to reduce the class load time. The following are the platform and oracle version.
