Oracle XML Gateway- Mapping XML to Oracle Apps API - Wrong Number or types

Question

XML GATEWAY INBOUND – CALLING AN API (PL/SQL record type IN variable) TO INSERT THE DATA INTO SAMPLE TABLE
Hi,
I am using XML Gateway to push data into Oracle Apps using a procedure call with “Record Type” as the parameter. I am getting a “wrong number” or types of arguments mismatch error inspite of following the process described in the Oracle XML Gateway User’s Guide
Steps followed:
DB
1. I Created a sample table XX_CUST_HIST(ID NUMBER, ACCOUNT_NAME VARCHAR2(50), FIRST_NAME VARCHAR2(50), LAST_NAME VARCHAR2(50), TITLE VARCHAR2(50))
2. I then Created a package ‘XX_XML_DEMO_API’ in which we have defined a record type and a procedure.
3. The Record type ‘customerRecordType’ holds account_name , first_name, last_name and the title.
4. The Procedure ‘insert_customer_r’ takes 2 IN arguments :
1. p_ id number
2. p_customer customerRecordType
5. The procedure will insert the values into xx_cust_hist table
p_id -> id
p_customer.account_name -> account_name
p_customer.first_name -> first_name
p_customer.last_name -> last_name
p_customer.title -> title
Now I need to call the procedure ‘XX_XML_DEMO_API . insert_customer_r’ from XML gateway.
Following are the steps to call the procedure:
[1] Create DTD
ELEMENT NEW_CUSTOMER_APIR (DATAAREA)
ELEMENT DATAAREA (CUSTOMER_DATA)
ELEMENT CUSTOMER_DATA (ID, CUSTOMER_RECORD)
ELEMENT ID (#PCDATA) ELEMENT CUSTOMER_RECORD (ACCOUNT_NAME, FIRST_NAME, LAST_NAME, TITLE)
ELEMENT ACCOUNT_NAME (#PCDATA)
ELEMENT FIRST_NAME (#PCDATA)
ELEMENT LAST_NAME (#PCDATA)
ELEMENT TITLE (#PCDATA)
[2] Creation of XML map Data Definition type for Source and Destination are set to XML.
While executing the procedure ‘XX_XML_DEMO_API . insert_customer_r’ in post_process from the message designer, instead of 2 (p_id IN number , p_customer IN customerRecordType) parameters it is showing 6 parameters (p_id IN number, p_customer IN customerRecordType, account_name IN varchar2, first_name IN varchar2, last_name IN varchar2, title IN varchar2). Six parameters are getting mapped, instead of the 2 that the procedure really needs.
[3] Testing of XML map. Error message in transaction monitor:
ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'INSERT_CUSTOMER_R' ORA-06550: line 1, column 7: PL/SQL: Statement ignored -
ECX_ACTIONS.BIND_PROC_VARIABLES
The process executed and produced the error message given in the step 3. The standard documentation is unclear on how this should be done. Being a newbie to the XML Gateway technology I am unable to get a clue about what the error message could be and which step of the process produced the message. Could anyone help me to proceed further?
Thanks in advance.

Hi Siva,
It seems like the walletkey property of event type is defined incorrectly. Please try by defining the event as follows:
<wlevs:property name="walletkey" type="char" length="20"/>
Use "char" instead of "char[]".
Best Regards,
