Michel, correct me here if I get it wrong please.

If I remember correctly, to call java from plsql, you don't.

What you do is create a plsql specification that maps to the java procedure. This effectively renames the java procedure and makes it look like a plsql procedure. then you call the plsql specification.

Do a google for this stuff, that is how I learned it. For example, I found this in three seconds...

9.8 Publishing and Using Java in PL/SQL

 standalone function calling a method:

CREATE OR REPLACE FUNCTION fDelete (
   file IN VARCHAR2) 
   RETURN NUMBER
AS LANGUAGE JAVA
   NAME 'JDelete.delete (
            java.lang.String) 
            return int';

Good luck, Kevin

You are perfectly right.
I did it short posting the link to the create java section as it itself points to the relevant documentation, among them Database Java Developer's Guide, Chapter 3 Calling Java Methods in Oracle Database
