Java stored procedure in Oracle 8i

Hi,
I read in the whitepaper of Oracle "Stored Procedure Tutorial", I have a little problem understanding the following syntax in the example enclosed, please help.
In Java environment the method:
public static void assignEMailAddress(Connection conn, int eno, String fname, String lname) throws Exception;
this method take 4 parameters, but when it is public to SQL, the parameter is ignored!
Is this understood by the DBMS?
Is this Connection-typed parameter must ALWAYS be the first one in the proceudre list or the procedure list can be in any order?
The tutorial is given in Oracle 8i, Lite, we will be using the real Entreprise Oracle 8i, does it make any difference in how we should load java stored procedure?
I really appreciate any help. thanks
null

Mapping between Java types and pl/sql types
can only be done for standard Java datatypes.
You cannot publish a java procedure accepting a Connection variable to PLSQL.
Hope this helps.

URGENT: Java stored procedure on oracle 92 database is not working

Hi,
I am having an issue regarding java stored procedures. I have created a java class that uses the bouncycastleprovider ( bcprov-jdk13-141.jar ) to encrypt strings. I tested against the version of the java virtual machine that comes bundled with oracle and it works perfectly. I then used JDeveloper to load the class on the database with the resolve, noverify and order flags checked and it shows no errors but when I try to execute the stored procedure it throws the following exception:
java.lang.ExceptionInInitializerError:
java.lang.SecurityException: Cannot set up certs for trusted CAs: java.net.MalformedURLException: no protocol: US_export_policy.jar
at javax.crypto.SunJCE_b.<clinit>(DashoA6275)
at javax.crypto.Cipher.a(DashoA6275)
at javax.crypto.Cipher.getInstance(DashoA6275)
at RijndaelEnhanced.encrypt(RijndaelEnhanced.java:57)
at RijndaelEnhanced.encrypt(RijndaelEnhanced.java:73)
I loaded jce1_2_2.jar, sunjce_provider.jar, bcprov-jdk13-141.jar. Also replaced the US_export_policy.jar, local_policy.jar with the unrestrictive version. I add the security provider dinamically with a call to Security.insertProviderAt(new org.bouncycastle.jce.provider.BouncyCastleProvider(), 2);
I also did a select on the user_objects table and all the classes are in VALID status.
When I run my application using the java virtual machine that is located under C:\Oracle\oracli9i\jdk\jre\bin directory it works fine but when I try to execute on the database it won't work. I found a bug that was if the jce1_2_1.jar file existed in the C:\Oracle\oracli9i\jdk\jre\lib\ext directory ( even if it's extension is renamed ) it won't work because the certification file had expired but I don't know if this has anything to do with this error.
Am I missing something?
Please I need an urgent solution to this problem.
Thanks in advance.

Hello,
Thanks for the reply. Actually I have seen that post before creating this thread. I thought that I could make use of java mail to work around this problem. I created a java class that succesfully sends mail to SSL host. I tried to call this java class from pl-sql through java stored procedure. That did not work
So, is this not supported in Oracle ? Please note that I have tested this in both 9i and 11g , in both the versions I got the error. You can refer to the code in the above post.
Thanks

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 Procedures and Oracle XE

Hi folks,
Does anyone know if Oracle XE supports Java Stored Procedures.
Thanks in advance,
Kris

Unfortunately you misunderstood me. I didn't call Oracle XE crippled, Yes, I did misunderstand. Apologies.
Bottom line - JMS is not extant. JMS and AQ are not quite the same thing.
AQ was developed back in early Oracle8 (8.0) (and possibly the late Oracle 7) days and seems to have been a pure PL/SQL implementation (probably with hooks at the C/C++ DB kernel level). The extensions that link to JMS came later.
Since JMS depends on Java, and since 'Java in the database' is not part of XE by design and well documented, I considered you comment
that JMS is not supported at all in Oracle XE or is at least
severly crippled.to be more than you apparently meant it to be,
AQ is 'supported' but lack of Java Stored Procs causes some limitations here as you have noted, as well as in Oracle Text and interMedia support.
I'd love to see Java in the database for future upgrades to XE.

Use of Java packages in Java stored procedures? (Oracle 10.2)

Hi all-
Does Oracle's Java stored procedures support Java packages? In all the examples I've seen, packages are never used, and when I added one to a test file, it compiled it just fine, but referencing the class from the package itself resulted in a compiling error.
In other words, it seems to make absolutely no difference if I preface my Java class with
package com.mycompany.whatever;
and while I can "import com.mycompany.whatever.MyClass" in another Java file, it seems to not care at all whether I do so or not.
Thanks for any clarification,
Ilford

Hi Ilford:
Sure you can use fully package notation in your Java classes.
Look at this Java source code:
http://dbprism.cvs.sourceforge.net/dbprism/cms-2.1/src/com/prism/cms/core/
All of them are Java Stored procedures.
Best regards, Marcelo.

JCE Based Java Stored Procedure in Oracle 8i

I have a Java class which is created based on JCE 1.2.1. I need to call this Java class from PL/SQL. Therefore, I want to create a Java stored procedure based on this Java class. I just read some topics in this forum and it seems that many people are unable to have JCE correctly setup on Oracle8 JVM.
My question is how to configure the JVM of Oracle8i to use the JCE?
I am using Oracle 8.1.6 on unix.
Thanks,

unfortunately, for JCE to work, you need a fix to OracleJVM that we will be providing in the next major release
Thanks for your reply.
The JCE optional package could be installed on SUN's JDK 1.2.x or higher. Since Oracle 8.1.6's JServer support SUN's JDK 1.2.1. Therefore, in theory, JCE could be installed for Oracle 8.1.6 or higher.
However, the cofiguration of JCE on the JVM requires the modification of Java security policy file. I followed the JCE's installation guide but it did not work on Oracle's JServer.
My question is: How to install JCE 1.2.1 on Oracle 8.1.6? Is it possible to configure the JVM of Oracle 8.1.x to use JCE? If yes, how?
Thanks,
JCE is an optional package even in J2SE 1.3 - it is required in J2SE 1.4
OracleJVM will be J2SE 1.4 compliant in the nest major release and we plan to support JCE

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:
1. OS: WinXP
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.

How to wake-up a Java Stored Proc at Oracle Server Startup

Hi,
I am writing a Java Stored Procedure responsible to
execute periodically (daily for example) a command (the
command and its arguments are prepared by the Java stored
procedure and they are date and time sensitive).
My questions are:
1. Is there any way that my Java stored procedure is
initially NOTIFIED (woke-up) when the Oracle server is
started ? I noticed that there is a built-in Java stored procedure in Oracle DB declared as:
"PROCEDURE notify_at_startup( user_schema VARCHAR2, classname VARCHAR2) ;"
Can this be used in any way for my purpose ? If yes, how ?
2. I can do the PERIODIC scheduling of execution of the
command using standard (SUN) java timer/Thread
primitives. Are there any Oracle Java classes/methods
which can be used instead for this scheduling ?
Thanks for any help/suggestions.
Arminius

I would look at two things.
1) Create a database level trigger that fires at server start up.
2) Define an Oracle Job that runs every xx minutes and restarts itself.

Invoking "java myClass" using Runtime.Exec from a Java Stored Procedure

Hi All,
This is regarding the use of Runtime.getRunTime().exec, from a java programme (a Java Stored Procedure), to invoke another Java Class in command prompt.
I have read many threads here where people have been successuful in invoking OS calls, like any .exe file or batch file etc, from withing Java using the Runtime object.
Even i have tried a sample java programme from where i can invoke notepad.exe.
But i want to invoke another command prompt and run a java class, basically in this format:
{"cmd.exe","java myClass"}.
When i run my java programme (in command prompt), it doesnt invoke another command prompt...it just stays hanging.
When i run the java programme from my IDE, VisualCafe, it does open up a command prompt, but doesnt get the second command "java myCLass".
Infact on the title of the command prompt (the blue frame), shows the path of the java.exe of the Visual Cafe.
and anyway, it doesnt run my java class, that i have specified inside the programme.
Even if i try to run a JAR file, it still doesnt do anything.
(the JAR file other wise runs fine when i manually invoke it from the command prompt).
Well, my question is, actually i want to do this from a Java Stored Procedure inside oracle 8.1.7.
My feeling is, since the Java Stored Procedure wont be running from the command prompt (i will be actually invoking it through a Oracle trigger), it may be able to invoke the command prompt and run the java class i want. and that java class has to run with the SUn's Java, not Oracle JAva.
Does any one have any idea about it?
Has anyone ever invoked a java class or JAR file in command prompt from another Java Programme?
YOur help will be highly appreciated.
(P:S- Right now, my database is being upgraded, so i havent actually been able to create a Java Stored procedure and test it. But i have tested from a normal java programme running in command prompt and also from Visual Cafe).
Thanks in advance.

Jena Adapter API access from Java Stored Procedures?

Is it possible to use Jena API from code in java stored procedures in Oracle DBMS 11gR2? Possible but not recommended?
The reason is that my company uses .Net as the application server plattform (not Java). Calling Java Stored Procedures from .Net is one way to use Jena library.
Thank you!
Trond

Hi Trond,
Unfortunately the sdordfclient.jar was compiled and built with JDK 6 and the JVM supported in the Oracle database 11gR2 is JDK5.
If you have a strong requirement, please file a SR against Oracle support. We will then look into a possible recompilation and
rebuild.

Calling a URL from a Java Stored Procedure

Hi,
I'm trying to call a URL from a Java Stored Procedure in Oracle 8.1.7(Windows 2000). The ultimate goal is to call this stored procedure from a database trigger. The status of the object remains invalid in the database even after compilation and publishing without any errors. The code follows. Any suggestions/alternatives to accomplish this would be appreciated.
Java Stored Procedure:
CREATE OR REPLACE JAVA SOURCE NAMED "UPDATEATTR" AS
import java.net.*;
import java.util.*;
import java.io.*;
public class UpdateAttr {
public static String testmain() {
ObjectInputStream is;
URL url;
String uri =
"http://www.yahoo.com";
try {
//calling the URL
url = new URL(uri);
URLConnection yahooConnection = yahoo.openConnection();
} catch (Exception e) {
e.printStackTrace(System.err);
return "TEST_SUCCESSFUL";
Code to Publish it:
CREATE OR REPLACE FUNCTION setNewAttributes return VARCHAR2
AS LANGUAGE JAVA NAME
'UpdateAttr.testmain() return String';
Thanks in advance.
Ris

Small mistake in the previous post. The object still has a status of "INVALID" though. The Java stored procedure should actually read:
Java Stored Procedure:
CREATE OR REPLACE JAVA SOURCE NAMED "UPDATEATTR" AS
import java.net.*;
import java.util.*;
import java.io.*;
public class UpdateAttr {
public static String testmain() {
ObjectInputStream is;

String uri =
"http://www.yahoo.com";
try {
//calling the URL
URL yahoo = new URL(uri);
URLConnection yahooConnection = yahoo.openConnection();
} catch (Exception e) {
e.printStackTrace(System.err);
return "TEST_SUCCESSFUL";
Code to Publish it:
CREATE OR REPLACE FUNCTION setNewAttributes return
