Create java class/resource from binary blob in SQL statement

Question

Is there a way of creating a java class or resource from a binary blob in the CREATE JAVA CLASS statement? Something like:
CREATE OR REPLACE JAVA CLASS
USING BLOB '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';
I've tried various combinations of casting & convert functions, all of them give an ORA-29506 error 'Invalid query derived from USING clause', and nothing useful is gained from google about this. Is there a way of specifying the class binary in this way?

Answer 1

You can load Java classes into the database, then create a PL/SQL procedure or function in the database that calls that Java class.
This leaves you with a standard PL/SQL procedure/function which you can call from Oracle Forms.
Have a look at the database documentation on how to load a Java class: http://download.oracle.com/docs/cd/A91202_01/901_doc/java.901/a90210/toc.htm
