Deploy package with Java Stored Procedure without JDeveloper

I have a set of Java Stored Procedures deployed as a package on a Oracle 8i server. Everything works fine in my development environment, and now I would like to deploy the same package in the customers runtime environment. Both environments are running Oracle 8i rel 2 on NT.
Is there a simple way to use the JDeveloper .prf deployment profile without installing JDeveloper in the customers environment?
If not, can I the get the .jar files and .sql scripts from JDeveloper to create the call specs and package bodys?
I guess JDeveloper must have this information, and my idea was then to write a script using loadjava and SQL*Plus.
Regards,
Tom Bjerre

you would not be able to take just the deployment profile and run it outside JDeveloper.
You would be able to create archive of all java classes in the package using Deployment Wizard in JDeveloper.
Then you can load the jar file using the utilities in 8i.
JDeveloper does generate the SQL for CALL specs etc ., at the deployment time and it is printed in MEssage Viewer along with other information.
Hope that info is useful for you

4gb file size limitation using java.io.* package in java stored procedure

Does anyone know about file size limitations when using java.io.* package inside java stored procedures. I have some java stored procedures that read and write to files. They error out when run as a java stored procedure within oracle on files over 4gb. I have no problems with these procedures when I test them outside of oracle.

I am using 10g Release 10.2.0.1.0, the java version returned by the Oracle JVM is 1.4.2_04
When I tested it outside of oracle I ran it using the java run time in ORACLE_HOME\jdk\bin and it works perfectly on files larger than 4gb.
Thank you for the UTL_FILE suggestion. I have considered using that but there is one method in Java that I can't seem to find a corresponding procedure for in PL/SQL.
RandomAccessFile.setLength()
This allows me to truncate a file. I have a need to strip bytes off the end of a file without creating a copy because I am working with large files and disk space may be limited. It is also much slower to read from the original file and writing the same bytes to a new file (minus the trailing bytes).
If anybody has any insight about the 4gb java.io limitation in Oracle JVM or has a workaround in PL/SQL for the RandomAccessFile.setLength() method in Java, I would really appreciate the help.
Thanks,
Thach

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.

Error while deploying a Java Stored Procedure using JDeveloper

Hi,
I was going thru the Oracle By Example article: "Developing SQL and PL/SQL with JDeveloper". (http://www.oracle.com/technology/obe/obe9051jdev/ide1012/plsqlobe/obeplsql.htm)

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

APEX fails with Java stored procedure that creates a JDBC connection

Hello!
We are facing a strange problem since we have upgraded from Oracle 10g and Apache to Oracle 11g with Embedded Gateway.
Here is what we do:
** APEXX calls a PL/SQL package function "OPEN_CONNECTION" that wraps a Java stored procedure called "openConnection".*
FILE_READER_REMOTE_API.openConnection(user, password, host, port, service);
** The Java stored procedures "openConnection" opens a JDBC connection to an other database:*
public class FileReaderRemote {
private static Connection conn = null;
private static DefaultContext remoteContext = null;
public static void openConnection(String user, String password, String host, String port, String service) throws SQLException {
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
java.util.Properties props = new java.util.Properties();
props.put ("user", user);
props.put ("password", password);
//props.put ("database", "//" + host + ":" + port + "/" + service);
props.put ("database", host + ":" + port + ":" + service);
props.put("v$session.program", "FileReaderRemote2");
// Connect to the database
remoteContext = Oracle.getConnection("jdbc:oracle:thin:", props);
This procedure used to work fine before the upgrade, but now we see the following:
* It still works when called directly from TOAD or SQL*Plus, even under the user ANONYMOUS.
* When called from APEX and the target database is Oracle 11g, it still works.
* When called from APEX and the target database is Oracle 10g, it takes several minutes and we receive this error:
*"Socket read timed out"*
We have tested the following workaround:
We have created a database link to our own database and called the stored procedure through that database link.
FILE_READER_REMOTE_API.openConnection*@loopback*(user, password, host, port, service);
This works, but is not really an option.
I hope some one of you can explain this strange behaviour to me.
Best regards,
Matthias

You wrote
"Java stored procedures -- by definition - are stored in the 8i rdbms. !!"
From the Oracle8i Java Stored Procedures Developer's Guide
Release 8.1.5
A64686-01
"If you create Java class files on the client side, you can use loadjava to upload them into the RDBMS. Alternatively, you can upload Java source files and let the Aurora JVM compile them. In most cases, it is best to compile and debug programs on the client side, then upload the class files for final testing within the RDBMS"
This means that you can create shared classes that are used on both the client and server side. The source does not need to reside within the server (according to their documentation). Please also note the following from the Oracle8i JDBC Developer's Guide and Reference Release 8.1.5 A64685-01 for using the getConnection() method on the server:
"If you connect to the database with the DriverManager.getConnection() method, then use the connect string jdbc:oracle:kprb:. For example:
DriverManager.getConnection("jdbc:oracle:kprb:");
Note that you could include a user name and password in the string, but because you are connecting from the server, they would be ignored."
So if you're coding a shared class that is to run on both the client and server side, you might do something like this:
Connection conn =
DriverManager.getConnection(
System.getProperty("oracle.server.version") == null
? "jdbc:oracle:thin:@hostname:1521:ORCL"
: "jdbc:oracle:kprb:"),
"youruserid","yourpassword");
As stated earlier, the userid and password are supposedly ignored for server connections retrieved in this manner. I haven't tried this yet, but it is documented by Oracle.

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

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.

For Java Stored procedures you'll need to use JDeveloper. For SQL Developer, there is a viewlet and a tutorial on this page:

Remote execution of DTS packages from Java Stored Procedures

I'm an Oracle 10G DBA and Linux/Unix Sysadmin looking for a Java guru to help me find a reusable template or locate a solid programming methodology (examples) that will enable me to connect via JDSI to SQL Server 2000/2005 and remotely execute DTS packages from within Oracle. I am working at office that's absolutely addicted to MicroSlop products and the DBA team cannot conceive of giving up their precious DTS packages. I've already converted their MS SQL Server 2000 database to Oracle 10G on RHEL4 via SQLDeveloper but I am unschooled in the art of java programming and would like to locate some sort of rudimentary template or examples or java class that can easily be loaded into the Oracle 10G database instance via the loadjava utility. These java classes/methods/stored procedures need to be executable from within embedded PL/SQL code and able to connect to SQL Server 2000 to execute DTS packages via passing dtsrun commands ... Any help or direction would be greatly appreciated.

Invoking Unix command with java stored procedure

Hi,
I have a perfectly working environment and now I am trying to replicate the same in another server. I have a java stored procedure which invokes the Unix command using java Runtime.exec() in my code named "run". I am sure that the code is called and the java class run is resolved in oracle as I could see that in dba_java_resolvers dictionary. But I am not sure whether the function in java is called or whether a exception is thrown. how to identify this? Could there be any thing to do with settings in oracle side? please help me.
Thanks in advance,
Marutha

Hi,
Do you get any output while running the code?
I'm testing similar solution and if there are any errors or Oracle can't execute the program due to permissions or other issues the error information will be displayed. Also in the Java class itself you need to catch exceptions and print stack trace to standard output.
declare
x number;
begin
dbms_output.enable(1000000);
dbms_java.set_output(1000000);
x:=system_command.run_command('testconnect.sh');
dbms_output.put_line('Returned value='||x);
exception
when others then dbms_output.put_line('Sql error='||substr(sqlerrm,1,250));
end;
<system_command.run_command> - replace with a call to your java stored procedure.

Using Java Resources with Java Stored Procedures

Hi folks,
Hope someone can help out with this one.
I have a java source file called PdfFormExtractor.sql. In that file I have a definition similar to.
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "PdfFormExtractor" as
import com.adobe.pdf.FormDataFormat;
import com.adobe.pdf.FormType;
import com.adobe.pdf.PDFDocument;
import com.adobe.pdf.PDFFactory;
etc, etc.
};I have loaded a number of Java jar files into the DB with the following command:
   CALL loadjava -v -s -r -u db_user_name/db_password@SID -jarasresource name_of_jar_file.jarMy PdfFormExtractor class compiles with errors as it does not seem to detect the class files located in the jar files which located in the schema.
I have used the following query and determined that the JAR files are valid and present in the schema.
SELECT object_name, object_type, status, timestamp
FROM user_objects
WHERE (object_name NOT LIKE 'SYS_%'
         AND object_name NOT LIKE 'CREATE$%'
         AND object_name NOT LIKE 'JAVA$%'
         AND object_name NOT LIKE 'LOADLOB%')
   AND object_type LIKE 'JAVA %'
ORDER BY object_type, object_name;One solution appears to be to omit the "-jarasresource". This appears to cause loadjava to unpack the jar files. Unfortunately this means that you must drop any java objects from the same path as which they were created. Ideally I'd like to just load the java files and leave them as resources.
My question then is how do I get my source code to recognize that the files are in the schema. I thought this would be picked up when I do @PdfFormExtractor.sql from a sqlplus prompt (assuming the jars have been loaded and unpacked in the schema)
because I specified RESOLVE in the source definition
If anyone has any ideas they are most welcome as I've been stuck on this for the past couple of hours.

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.

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.
