Where are java classes stored in Oracle?

Where is the java bytecode for loaded java classes stored within an oracle database? Specifically, is there a view or table I can use to obtain the raw bytes for java class schema objects within Oracle?

From stackoverflow

• If you have used CREATE JAVA SOURCE command to load the Java Source into the Oracle database then you can go to the data dictionary view USER_SOURCE and find your Java Source.

  If you need to display it or something, you can check out DBMS_JAVA.EXPORT_SOURCE which puts the source code in PL/SQL structures that you can manipulate.

  Generally, if you want to just list all Java related stored objects you can execute the following:

  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;
  

• Java bytecode stored in IDL_UB1$ table: select o.NAME, i.PIECE from obj$ o, IDL_UB1$ i where o.type# = 29 and o.obj# = i.obj#
