Call java procedure from oracle 8.1.7

Hi all,
I want to loadjava from a javaclass which was compiled in jdk 1.3 into oracle 8.1.7
Anyone help me to do it
thanks a lot
anhnt

Anhnt,
Please refer to the following books, that are part of the Oracle documentation:
Java Developer's Guide
Java Stored Procedures Developer's Guide
Java Tools Reference
The documentation can be accessed from:
http://tahiti.oracle.com
Although Oracle 8i is very old by now, you may still find some useful information from the OracleJVM and Java Stored Procedures Web page.
Good Luck,
Avi.

Calling Java programs from Oracle Stored Procedure

Is it possible to call Java programs from Oracle stored procs? If possible Can this be used to exchange data from other applications? Is there a better method/feature in oracle for doing data exchange with other apps?

If what you mean by Oracle stored procedures is pl/sql then yes.
You can create a "wrapper" this way:
CREATE OR REPLACE FUNCTION xmlXform
in_mapUrl IN VARCHAR2,
in_inputUrl IN VARCHAR2
RETURN VARCHAR2
AS
LANGUAGE JAVA NAME
'com.yourcompany.xml2any.xform(java.lang.String,java.lang.String)
RETURN java.lang.String';
Then load the java as:
loadjava -user youruser/youruserpasswd -resolve -verbose lib/xmlparserv2.jar classes/com/yourcompany/xform.class classes/com/yourcompany/xml2any.class
The java, given the correct permissions, can do anything java can do including communicate with outside applications.
Is this the "best" way... depends on what you are trying to accomplish.

Calling Stored Procedure from Oracle DataBase using Sender JDBC (JDBC-JMS)

Hi All,
We have requirement to move the data from Database to Queue (Interface Flow: JDBC -> JMS).
Database is Oracle.
*Based on Event, data will be triggered into two tables: XX & YY. This event occurs twice daily.
Take one field: 'aa' in XX and compare it with the field: 'pp' in YY.
If both are equal, then
if the field: 'qq' in YY table equals to "Add" then take the data from the view table: 'Add_View'.
else if the field: 'qq' in YY table equals to "Modify" then take the data from the view table: 'Modify_View'.
Finally, We need to archive the selected data from the respective view table.*
From each table, data will come differently, means with different field names.
I thought of call Stored Procedure from Sender JDBC Adapter for the above requirement.
But I heard that, we cannot call stored procedure in Oracle through Sender JDBC as it returns Cursor instead of ResultSet.
Is there any way other than Stored Procedure?
How to handle Data Types as data is coming from two different tables?
Can we create one data type for two tables?
Is BPM required for this to collect data from two different tables?
Can somebody guide me on how to handle this?
Waiting eagerly for help which will be rewarded.
Thanks and Regards,
Jyothirmayi.

Hi Gopal,
Thank you for your reply.
>Is there any way other than Stored Procedure?
Can you try configuring sender adapter to poll the data in intervals. You can configure Automatic TIme planning (ATP) in the sender jdbc channel.
I need to select the data from different tables based on some conditions. Let me simplify that.
Suppose Table1 contains 'n' no of rows. For each row, I need to test two conditions where only one condition will be satisfied. If 1st condition is satisfied, then data needs to be taken from Table2 else data needs to be taken from Table3.
How can we meet this by configuring sender adapter with ATP?
================================================================================================
>How to handle Data Types as data is coming from two different tables?
If you use join query in the select statement field of the channel then whatever you need select fields will be returned. This might be fields of two tables. your datatype fields are combination of two diff table.
we need to take data only from one table at a time. It is not join of two tables.

Calling stored procedures from oracle ADF

hi all ,

Thanks Dear ! i also got it from JDeveloper Help with topic About Using Stored Procedures
and it is very brief with code and example...... and the link you forward to me is very valuable for me ... Thanks again.....

Calling Java Constructor from Oracle Stored Procedure

Hi all,
I have come across a situation where on insert into one Oracle database instance, a trigger will be fired which will call a procedure which in turn calls a Java constructor with 2 string arguments(The Java class is loaded into another instance of Oracle using Loadjava).
(Note: I don't want to call a static method from the Oracle procedure)
I have seen some examples where in using links, on insertion into a table another table of another instance can also be updated.
for ex: "INSERT INTO testuser.sal_audit@mainlink VALUES (?, ?, ?)" where "mainlink" is a DB link between the 2 instances.
Similarly is it possble to call the Java constructor loaded in another instance?
I have tried in this way. It's not working.
create or replace procedure pr_Cust_object(FeData varchar2,szDummy varchar2) as
LANGUAGE JAVA NAME
'CustomObject@mainLink(java.lang.String, java.lang.String)';
end pr_Cust_object;
Expecting help at the earliest--ASAP.
Thanks and Regards,
Narendra S K

I don't know how to do that, but I would be interested in knowing how long each insert/update/delete (which ever the trigger fires on) takes.
And the logic for rollbacks is probably really interesting.

Calling Java screens from Oracle Forms application

I am working with a client that has a large Oracle forms application. Since rewriting the entire application in Java is not an option at this time, the strategic direction is that any new modules that are to be created for the application are to be done in Java and called from the Forms menu. The decision as to what tool to use to develop the Java modules is still under debate. What is the best (most seamless) way to do this...calling a Java screen from a Forms application? If anyone has any experience in this, or can direct me to some literature on it, it would be greatly appreciated. Thanks.

This is a web app in Forms/Reports 10g R2 running off Oracle AS and an Oracle db. The challenge for us is that the direction is that any new enhancements (screens) are to be built using Java (in either ADF Faces or Swing, another point for debate later) and then called from the Forms app. The business client is only paying for the enhancement. They don't care about moving off Forms to Java, so any extra work on the part of IT to do this, has to be fairly minimal and doable within the project budget. The movement to Java is an IT direction. Is there a way to do this without having to build a java framework for the entire Forms application (which I assume would take some time and involve retesting the entire app)?

Calling a procedure from Oracle Forms with OUT parameter

Calling java application from Oracle forms button

Hi all,
I have a problem. The idea is to call Java desktop application when button is pressed. I have used this (above) line of code, but there is no results. When I start form in local everything is fine but when I start from server it doesn't work. Does anyone has that kind of problem and how is solved?
Thanks in advance.
__Code is:__
DECLARE
v_path VARCHAR2(1000);
BEGIN
v_path:= '\\location\Java_Application.jar';
HOST(v_path);
END;

First, please start here:
http://blogs.oracle.com/shay/2007/03/02/
As for what you are doing and the problem, it will be difficult to give an exact reason, but here are a few comments which will apply regardless of the platform, version, and installation type.
1. In most case, when calling HOST from Forms the shell that is started does not include all of the system environment variables. This means for example, if a java.exe is needed (on Windows), you would need to specify its path as part of the call or use a batch file rather than calling a command or app directly. The batch file would first set all the needed environment variables (i.e. PATH, CLASSPATH, etc)
2. If you are running a newer version of Forms, you have a middle tier. This is were your HOST call will be executed. So, if you are expecting this to occur on the client it will not work. You would need WebUtil for client side calls.
3. Calling a network resource (i.e. shared drive) is not permitted on Windows platforms when called from a Windows Service. Doing so can be seen as a security vulnerability. This can be overridden, but I would suggest that doing so is not a good idea. All files needed to run your app should be made available locally. If files exist on a remote machine, they should be temporarily brought to the machine (e.g. using ftp, sftp, etc) where they are needed and removed later if necessary. If you are running a newer version of Forms, the Forms runtime process belongs to a Windows Service, even if indirectly as a child.
4. Calling a jar directly is not the proper way to call a java app. Refer to the following:
http://download.oracle.com/javase/tutorial/deployment/jar/run.html

Calling Java procedure from PL/SQL (10g)

Hi.
I'm a newbie in Oracle 10g... could you, please, advice any documentation about restrictions put on java code so I could easily load in to 10g DB and call from a PL/SQL procedure?
I've only found some books for 8i and 9i :(

I've only found some books for 8i and 9i :( It hasn't changed that much. Have you tried those techniques?
Anyway, the best place to start is always the documentation, in this case the Java Developer's Guide.

Calling java code from oracle apps form

I've created my own java .class file and am attempting to call it from an oracle applications form. I am getting a runtime error while running the form, but I don't know what the error is because nothing is being reported to me.
I've created the .java file in JDeveloper, compiled it into a .class file, deployed it to a .jar file, and placed it on the application server in a directory that the CLASSPATH can see it. I've added it to the archive parameter of the appsweb.cfg file and see that the .jar file is being downloaded when the JInitiator of Oracle Apps is started.
I have also imported the .class file into the form via the Program -> Import Java Classes which resulted in PL/SQL package stubs created to call the .class methods.
When I run the form, the java code is activated on a triggering event, PRE-INSERT. There is no java bean item in a block or on a canvas anywhere. I dont' think I need there to be since I am simply using the java code to perform actions during PRE-INSERT, not to display anything on the canvas.
I have placed debug messages throughout my code and see that the error is occuring in the PL/SQL packaged stub at the line "JNI.GET_CLASS()" where the parameter to that call is the name of my class. I know it's erroring there because I am handling the "java_error" exception. I am displaying "ora_java.last_error" in the exception handling, but it is null.
I am at a loss as to determine why I am having problems and how to display an error. Any suggestions? I'm happy to outline my steps and problem in more detail if I have missed something obvious.
We are using Forms 6.0.8.21.3 with Oracle Apps 11.5.7.
Shane.

Shane,
Don't loose the heart. You have come too close to end.
The scenario you have mentioned is very unique and something which will fit more in the forms forum. So I think that was a sincere answer to help you and not a "pass the buck" card type game :)
You are lucky that you got Tapash interested into this issue, otherwise you see there is no OAF component involved out here.
I have an article promised to some of the guys but will follow this issue.

Calling Java Methods from Stored Procedures

Can I call Java Methods from Oracle Stored Procedures? I have a Java framework that logs events and would like to reuse it for logging events that occur in stored procedures.
null

You need to publish java class methods to plsql.
Attached below is some information.
Although both PL/SQL modules and Java classes are stored in the database
and are managed by many of the same mechanisms, each of them resides in
its own namespace. Therefore, Java methods are not accessible from SQL
and PL/SQL by default. In order to expose Java methods to the SQL and
PL/SQL engines, first publish that Java method to the SQL namespace using
a 'Call Spec'.
Note: A 'Call Spec' does not create an additional layer of
execution so there is no performance penalty incurred.
A 'Call Spec' is simply a syntactical mechanism used to
make a method known in the SQL namespace.
The SQL name established by the 'Call Spec' can be top-level or packaged.
The syntax differs only slightly and is consistent with that used for
PL/SQL procedures and packages. For more information on the exact
syntax, see the references listed in 'Related Topics'.
In general, a top-level procedure 'Call Spec' takes the form:
CREATE OR REPLACE PROCEDURE procname ( pname mode ptype, ... )
AS LANGUAGE JAVA NAME 'javaname ( javatype, ... )';
Where: procname is the SQL name you wish to publish
pname is the name for a parameter to procname
mode is the parameter mode (i.e. IN, OUT, IN OUT)
ptype is a valid SQL type (e.g. NUMBER, CHAR, etc.)
javaname is the fully qualified name of the Java method
javatype is a Java type for the corresponding parameter
Likewise, a top-level function 'Call Spec' takes the form:
CREATE OR REPLACE FUNCTION fname ( pname mode ptype, ... ) RETURN rtype
AS LANGUAGE JAVA NAME 'javaname ( javatype, ... ) return javatype';
Where: fname is the SQL name you wish to publish
rtype is the SQL return type of the function
Note: Within the NAME clause, everything within quotes is case
sensitive. For example, if the keyword 'return' is in all
CAPS, this Call Spec will not compile.
Other optional parts of this syntax have been omitted here for simplicity.
Additional examples in subsequent sections illustrate some of these options.
eg
CREATE PROCEDURE MyProc (rowcnt IN NUMBER, numrows OUT NUMBER)
AS LANGUAGE JAVA NAME 'MyClass.MyMethod(int, int[])';
There are several important things to note here:
1.) The 'Call Spec' for a JSP must be created in the same schema as the
corresponding Java class that implements that method.
2.) IN parameters are passed by value. This is the only parameter mode
available in Java. OUT parameters, therefore, must be passed as single
element arrays in order to emulate pass by reference.
3.) Parameter names do not need to match, but the number and types of
the parameters must match (with just one exception - see item 5 below).
Oracle 8i supports conversions between an assortment of SQL and Java.
See the references listed in 'Related Topics' for additional information.
4.) Primitive types (e.g. int, float, etc.) are not required to be fully
qualified with any package name. However, standard Java object types
(e.g. String, Integer, etc.) as well as any user defined object types
(e.g. like those generated by JPublisher) must be prefixed with a
corresponding package name (e.g. java.lang) if applicable.
5.) The 'main' method which takes a single String[] parameter can be
mapped to any PL/SQL procedure or function which takes some number
of VARCHAR2 or CHAR type IN parameters. For example, the java method:
public static void main ( String[] args ) { ... }
can be mapped to each of the following:
PROCEDURE MyProc2 ( arg1 IN CHAR ) ...
PROCEDURE MyProc3 ( arg1 IN CHAR, arg2 IN VARCHAR2 ) ...
PROCEDURE MyProc4 ( arg1 IN VARCHAR2, arg2 IN VARCHAR2 ) ...
and so forth. Parameters map to the corresponding element of the String
array (e.g. arg1 -> args[0], arg2 -> args[1], etc.).

Java bean from oracle Forms6i

Hi Guys,
I am calling java bean from oracle Forms6i (implementation
class property set to bean class). This java bean in turn
calling some JNI methods written in C. The application server
(Forms6i) is hanging at the point of calling the JNI method.
Is oracle Forms6i supports all java functionality (JNI here)
and if so how to solve the problem ?
Any pointers or tips in this regard is highly appreciated ?
Thanks & Regards
Chandra Mohan

To call Java from forms:
look at the technical documents on Java integration at
http://otn.oracle.com/products/forms
and also look at the Javabeans and PJC samples in the sample
code section of Forms on OTN.
Creating a random number using a java class is an excelent
example of how to use Java with forms.

Curious thing while calling a procedure from Java !...

Hi !. My name is Agustin and my doubt would be the following one... I am working for a e-business comp and they asked me to call a procedure from java... The code is the following one:
CallableStatement cs = null;
System.out.println("Fecha Nro. 1: " + paramFechaDesde);
System.out.println("Fecha Nro. 2: " + paramFechaHasta);
try
cs = getDBTransaction().createCallableStatement("{call paq_w_ListadoSiniestralidadART. p_sinsiniest(?,?,?,?) }",0);
cs.registerOutParameter(4,OracleTypes.VARCHAR);
cs.setInt(1,paramContrato.intValue());
cs.setString(2,paramFechaDesde);
cs.setString(3,paramFechaHasta);
cs.setString(4,paramNombreArchivo);
cs.executeQuery();
String nomArchivo = cs.getString(4);
System.out.println("### " + nomArchivo +" ###");
catch(SQLException e)
The weird thing is that, I was expecting a big big exception but the only thing I got is
### Error ###
The String I am expecting is a file's name !; so I am a little bit confused...
Also I didn't know where to post so If it's in the wrong category... I apologize !... If anyone need more details, I'll be checking out... The account I am working on is an Insurance company, who is the one who provide access to the DB and the procedures... So I can't check what's inside...

Please provide your Java and OS versions, the JDBC jar file and the Oracle DB version being used when you post.
>
I was expecting a big big exception
>
Then why do you have an empty exception block? That just makes it disappear so you won't see one if it happens.
And your code has
cs.registerOutParameter(4,OracleTypes.VARCHAR);
cs.setString(4,paramNombreArchivo);You use 'registerOutParameter' for an OUT parameter and the 'setXXX' methods for other parameters.
Remove the 'setSTring' for the OUT parameter.
Then as malcollmmc already said
>
Sounds like the PL/SQL is returning "Error" as the 4th parameter of the call
>
The actual value returned by PL/SQL is strictly determined by the PL/SQL code and Java and JDBC are not involved.
Fix the code problems, retest, and folllowup with whoever wrote the code if it still returns ERROR.

Calling java classes from plsql procedures

I'm attempting to call java classes from plsql procedures which will create cmsdk users, folders, groups etc, however when I attempt to load a java class into the oracle schema using the command:
loadjava -user user/password@database -resolve classname.class
It generates error messages to the effect that classes (cmsdk classes) required by the class cannot be found. The class is loaded and marked with the status "invalid". Is it therefore necessary for me to load the cmsdk packages into the schema?
Cheers
David

Using CMSDK Java API within the database has never been supported
(see Problems loading IFS's java class into database
When we needed to invoke CMSDK code from our PL/SQL code, we used one of two approaches:
(1) use advanced queues to send requests to an external Java program (the CMSDK code, running outside the database) and receive the results back (asynchronous choice); or
(2) make an HTTP request to a Java servlet (the CMSDK code, running in some Java web container like iAS) and get the response back in some custom format (XML or something) (synchronous choice).
It seems to me that the CMSDK Java API was designed to be used only in middle-tier, not in database tier.

Daniel.
