Using Directory alias in Java stored procedure

hi !!
I want use Directory alias in Java strored procedure
I 'hv created dir alias as
Create Directory BFILE_DIR AS 'C:\MyImages'
my java statements -
myfile="C:\MyImages\myPH01.jpg"
File binaryFile = new File(myFile);
instead of giving absolute path I want give directory alias BFILE_DIR
myfile= BFILE_DIR + "myPH01.jpg"
can anyone pl suugest how should I write this in Java procedure
thanks

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?
Thanks

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

Using socket programming in java stored procedure

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?
The server and the database is in the same pc and the server is just a small program listening to a port. Hope someone can help me thanks

"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.

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.

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

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.

Deploying SQLJ classes as Java Stored Procedures using JDeveloper 10g

Hello,
I have defined a SQLJ class, MwaSqljDao.sqlj, in JDeveloper. When I right click on the SQLJ class and "make" the class. It appears to succeed.
However when I attempt to build the project in which the SQLJ class is a member of, a class that uses the SQLJ class has the following compile error:
- MwaSqljDao not found.
After a little digging it appears JDeveloper is able to compile the .sqlj file to a .java file in the classes output directory. However it does not take it to the next step of compiling the .java file into a .class file.
Is SQLJ still a main stream Oracle technology? Or has it been cast to way side to make way for other technology?
If SQLJ is still a supported Oracle technology how do go about compiling the SQLJ class using JDeveloper?
My goal is to deploy SQLJ into JServer as a Java Stored Procedure class.
Thank you,
Rob

Excellent.
Especially that you resolved it and even more so that you posted the solution.
I do wonder whether you would have gotten help (faster) has you asked in a JDeveloper-related forum such as " Forum Home » Developer Tools » JDeveloper and ADF" at JDeveloper and ADF

ORA-04030: out of process memory when using Java Stored Procedures

Hello,
I have a problem using Java Stored Procedures in Oracle 10g.
My Java application performs http posts to a webservice and the response is parsed in order to populate some DB tables.
There is a scheduled job which calls the Java Stored Procedure every x minutes.
No matter of the 'x minutes' values - after about 160 - 200 calls I get this error:
ORA-04030: out of process memory when trying to allocate 1048620 bytes (joxp heap,f:OldSpace)
ORA-04030: out of process memory when trying to allocate 2097196 bytes (joxp heap,f:OldSpace)
The job stops just while is posting the http request. The weird thing is that almost each time the first http post request I get this error:
java.net.ConnectException: Connection refused
     at java.net.PlainSocketImpl.socketConnect(Native Method)
     at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)

So, The out of process memory occured each time just before getting such an error, and I suspect to be a connection between these errors.
Tech details:

2. Oracle 10.1.0.2.0
3. To perform http post I use HttpClient 3.1 from Apache.
4. I checked the http connection to be closed each time, and this is done.
5. I checked the oracle statement and connection to be closed each time and this is done
6. The JVM error (logged in .trc files of Oracle) is:

Can be a problem with JVM threading under Oracle ?

The server prcess failed to allocate more memory for large objects ( in Oldspace).
If you Google ORA-04030, you will see several recommendations to work around this.
The Java VM in the database already has HttpClient, i don't know why you are loading the Apache HttpClient but this might not be the surce of the problem.

Using a OracleOCIConnection object in a Java Stored Procedure

Hi,
I'm trying to use a OracleOCIConnection in a Java Stored Procedure, but the JVM seems to be 1.3, so it doesn't support this object, how can I update the JVM to 1.4 or just load the necessary classes? I tried to load the ojdbc14.jar to the system's schema but the user needs a LoadClassInPackage permission, and I confess it scared me..

Java Stored Procedure using XSU on 9i Lite

I have create Java Stored Procedure using XML SQL Utility to return results in XML format. I have tested the stored procedure on the development machine (with SDK and Webtogo)without any problem. When I tested it on the client machine (with only the lite database for Window download from the webtogo server as part of the setup), there's an error [POL-8035] no such attribute or method when I call the procedure through MSQL. However, after calling the stored procedure the 3rd times, it will return the results in XML. Once I logout after that, I will have to call the same SP 3 times (always 3 times) before I get the results.
I'm running on Win2000, Oracle lite 5.0.1. with jdk 1.3.1 - same for the development machine.
I'm using the same xsu12.jar file.
What did I miss?

Nothing?
No one? No ideias?
