How to handle table type record in OAF

Question

Hi ,
Req:
There is a search page that can be accessed from different locations .
The result set should be different when accessed from each location .
Approach to be used :
Call a PL/SQL api which returns a table type input parameter for different search conditions . Each record that is returned by the table type input needs to be iterated and a new row should be created in a transtient VO to show results on the UI
Problem :
How to handle to table type input returned from pl/sql in java and show the results?
Thanks in advance.

There is a requirement to fetch records from cursor into a collection .Following is the code snippet that I have used.
/** creating an object **/
CREATE OR REPLACE TYPE XXCRM_GBL_DSW_AUDIT_RSTLS_O_TP AS OBJECT (
CUSTOMER_NAME VARCHAR2(360),
PROJECT_NAME VARCHAR2(40),
BOARD_NAME VARCHAR2(40),
ARROW_UNIQUE_NO NUMBER,
FIELD_NAME VARCHAR2(2000),
OLD_VALUE VARCHAR2(2000),
NEW_VALUE VARCHAR2(2000),
USER_ID NUMBER,
USER_NAME VARCHAR2(100),
AUDIT_DATE DATE,
AUDIT_TYPE VARCHAR2(1),
SUPP_SYS_LAST_UPDATE_ON DATE,
SUPP_TRACKING_NUM VARCHAR2(50),
CONSTRUCTOR FUNCTION XXCRM_GBL_DSW_AUDIT_RSTLS_O_TP
RETURN SELF AS RESULT
/** initializing the object **/
CREATE OR REPLACE TYPE BODY XXCRM_GBL_DSW_AUDIT_RSTLS_O_TP IS
CONSTRUCTOR FUNCTION XXCRM_GBL_DSW_AUDIT_RSTLS_O_TP
RETURN SELF AS RESULT IS
BEGIN
self.customer_name := fnd_api.g_miss_char;
self.project_name := fnd_api.g_miss_char;
self.board_name := fnd_api.g_miss_char;
self.arrow_unique_no := fnd_api.g_miss_num;
self.field_name := fnd_api.g_miss_char;
self.old_value := fnd_api.g_miss_char;
self.new_value := fnd_api.g_miss_char;
self.user_id := fnd_api.g_miss_num;
self.user_name := fnd_api.g_miss_char;
self.audit_date := fnd_api.g_miss_date;
self.audit_type := fnd_api.g_miss_char;
self.supp_sys_last_update_on := fnd_api.g_miss_date;
self.supp_tracking_num := fnd_api.g_miss_char;
return;
END;
END;
/** creating a collection of object**/
CREATE TYPE XXCRM_GBL_DSW_AUDIT_RSTLS_C_TP AS TABLE OF XXCRM_GBL_DSW_AUDIT_RSTLS_O_TP;
/**Inside the package body **/
CURSOR c_proj_cur is
SELECT NULL CUSTOMER_NAME,
(SELECT project_name
FROM xxcrm_gbl_dsw_projects_all
WHERE project_id = xgda.project_id) PROJECT_NAME,
DECODE(xgda.board_id,NULL,'test',
(SELECT board_name
FROM xxcrm_gbl_dsw_boards_all
WHERE board_id = xgda.board_id)) BOARD_NAME,
DECODE(xgda.internal_dwr_id,
NULL,NULL,
(SELECT internal_dwr_id
FROM xxcrm_gbl_dsw_regstrations_all
WHERE internal_dwr_id = xgda.internal_dwr_id)) ARROW_UNIQUE_NO,
fielslu.meaning FIELD_NAME,
xgda.old_value OLD_VALUE,
xgda.new_value NEW_VALUE,
xgda.created_by USER_ID,
'kuldeep' USER_NAME,
xgda.Creation_Date AUDIT_DATE,
xgda.audit_Level AUDIT_TYPE,
SYSDATE SUPP_SYS_LAST_UPDATE_ON,
't001' SUPP_TRACKING_NUM
FROM XXCRM_GBL_DSW_AUDIT_ALL xgda ,
FND_LOOKUP_VALUES_VL fielslu
WHERE xgda.project_id =174
AND fielslu.lookup_type = 'XXCRM_DSW_REV_FIELD_NAMES'
AND fielslu.lookup_code = xgda.FIELD_NAME
AND enabled_flag = 'Y'
AND TRUNC(SYSDATE) BETWEEN TRUNC(NVL(fielslu.start_date_active,sysdate))
AND TRUNC(NVL(fielslu.end_date_active,sysdate))
ORDER BY xgda.creation_date;
Tab XXCRM_GBL_DSW_AUDIT_RSTLS_C_TP ;
BEGIN
OPEN c_proj_cur;
LOOP
FETCH c_proj_cur BULK COLLECT INTO tab; --ERROR type mismatch found at 'TAB' between FETCH cursor and INTO variables
END LOOP;
END;
/**Error */
When the above script is executed it gives an error “type mismatch found at 'TAB' between FETCH cursor and INTO variables” (at line highlighted above).
I have validated the data type of cursor and object too. But still the error is not resolved .
Did anyone of you come across a similar requirement, fetching the values from cursor into a collection? Please help.
