Jdeveloper 11g R2 problem when publishing PL\SQL Web Service

Question

Hi Guys,
I have been banging my head against the wall for the past few days trying to publish pl\sql package as a web service on a weblogic 10.3 but I keep running into the same problem.
PL\SQL Package Source below
create type dept_type as object
(deptno NUMBER,
dname VARCHAR2(50),
loc varchar2(13),
cr_date date)
create type dept_list_table is table of dept_type
purge recyclebin;
create or replace package ws_package as
procedure test_dept_table (pout out dept_list_table);
end ws_package;
show errors;
create or replace package body ws_package as
procedure test_dept_table (pout out dept_list_table) is
all_depts dept_list_table := dept_list_table();
dRecType dept_type;
i number := 0;
begin
-- iterate through all depts
for r_list in (select * from dept) loop
i := i + 1;
dRecType := dept_type(null, null, null, null);
dRecType.deptno := r_list.deptno;
dRecType.dname := r_list.dname;
dRecType.loc := r_list.loc_id;
dRecType.cr_date := sysdate;
pout.extend;
pout(i) := dRecType;
end loop;
end test_dept_table;
end ws_package;
show errors;
I go and create PL\SQL Web Service using default settings in Jdeveloper 11g R2 but when I try and test this page I get the following response:
Failed to invoke end component servqa.MyWebService1User (POJO), operation=testDeptTable -> Failed to invoke method -> java.sql.SQLException: ORA-06550: line 1, column 13: PLS-00306: wrong number or types of arguments in call to 'TEST_DEPT_TABLE' ORA-06550: line 1, column 7: PL/SQL: Statement ignored
Anyone have any idea what the problem may be? Your help would be much appreceated!

Hi Frank,
I think the problem is in any procedure that has a COMPLEX TYPE as OUT parameter. So even if you strip down the procedure to just do nothing I still get the error as described in my top post. Passing complex parameters as IN parameter work fine its only when I have procedure with complex out when it errors. I also tried function that returns object parameter and that works fine too so not sure why this doesnt?
create or replace package body ws_package as
procedure test_dept_table (pout out dept_list_table) is
begin
-- iterate through all depts
for r_list in (select * from dept) loop
i := i + 1;
end loop;
end test_dept_table;
end ws_package;
Not sure if I am meant to do anything extra before I generate Web Service using JDeveloper if my procedure has got PL\SQL types as OUT parameters but as far as I know JDeveloper should do all the type conversions for you??
Thanks
