My customer wants to be able to call a jar file from Oracle PL/SQL.
Java 1.6, Oracle 11g R2
How do I do this?

I did a bit of research into loadjava (the program that loads classes into Oracle). Sounded like a pain in the butt.
So I opted to run my jar outside Oracle but called from Oracle DBMS_SCHEDULER by PL/SQL.
Here's how:
BEGIN
DBMS_SCHEDULER.CREATE_PROGRAM (
program_name => 'testjar',
program_type => 'EXECUTABLE',
program_action => 'C:\MYSTUFF\testjar.bat',
enabled => TRUE,
comments => 'test testjar'
);
END;
/
begin
dbms_scheduler.create_job
(job_name => 'testjar_job',
program_name=> 'testjar',
enabled=>true,
auto_drop=>false,
comments=>'Only run immediately by dbms_scheduler.run_job');
end;
/
begin
dbms_scheduler.run_job('testjar_job',TRUE);
end;
/

I agree with you Hog..But I think that is not enough :)
After playing around I found out that the schema JAR_NAME.jar///ClassName.methodName(.... works.
So for example:
Function do()
return String
AS
LANGUAGE java
NAME 'my_jar.jar///MyClass.myMethod() return oracle.sql.String';
Note that it seems like some jar name files does not work. For example I had problems with a "-" in jar.
