trying to export java source code from an Oracle database

I am trying to export the source for a java object from an oracle database using the following code.

DECLARE
  blob1 BLOB;
BEGIN
  DBMS_LOB.CREATETEMPORARY开发者_StackOverflow社区(blob1, FALSE);
  DBMS_JAVA.EXPORT_SOURCE('OBJECTNAME', 'SCHEMANAME', blob1);  
END;

Whenever I try to run it, I get this exception:

oracle.aurora.rdbms.ModifyPermissionException

even though I am running as System. Any ideas what is causing this and how I can get this to work.

Having investigated a bit more it worked when running as sysdba and also as the user that owns the objects. Unfortunately I am making a program to dump out the java objects in an Oracle database and I can't really force my users to be sysdba or the object's owner.

Is there any way I can stop this error?

When you connect use "as sysdba" option. I don't get ModifyPermissionException when I login as sysdba. See my actions below. The ORA-29532 I am getting is becuse I simply don;t have the Java class in my database. let me know if it worked for you.

I am facing the same problem, but after a few searches on google I solve it. Probably will help someone.

DECLARE 
 b CLOB;
 c varchar2(2000);
 i integer:= 255;
begin
  DBMS_LOB.createtemporary(b, false);
  DBMS_JAVA.export_resource('<object_name>', '<schema_name>', b);
  DBMS_OUTPUT.PUT_LINE('java_resource:');
  DBMS_LOB.read(b, i, 1, c);
  DBMS_OUTPUT.PUT_LINE(c);
end;
