Sys.UTL_DBWS issue when calling web service .......

Question

Hi,
Background Details :
Linux : 2.6.18-164.10.1.0.1.el5 #1 SMP Fri Jan 8 02:34:10 EST 2010 x86_64 x86_64 x86_64 GNU/Linux
Web Server : Apache Tomcat 6.0.20
Database : Oracle 10.2.0.4
Utility that we use to consume the Web Service from PL/SQL : JPublisher 10g Release 2 (10.2)
Load Balancer : Citrix Netscaler
We are using the Oracle built in package called UTL_DBWS to invoke the Java web service. The web service is been called through a Load Balancer called Citrix Netscaler.
Load balancer has been configured to use the Source IP mechanism to route the request to the appropriate web service.
Problem :
When invoking the web service from Pl/SQL (with the below piece of code) there are multiple times the web servers are been called which is supposed to be only once. The number of times the call varies is about to 2 or 3.
Query :
Hence we need to understand in general how the UTL_DBWS works ? Are there any issues when the call being made through the LoadBalancer ?
The default time out value while connecting ? If we want to override the default timeout how we can do that ?
Code for reference :
BEGIN
l_service := sys.UTL_DBWS.create_service (
wsdl_document_location => sys.URIFACTORY.getURI(l_wsdl_url),
service_name => l_service_qname);
l_call := sys.UTL_DBWS.create_call (
service_handle => l_service,
port_name => l_port_qname,
operation_name => l_operation_qname);
l_input_params(0) := sys.ANYDATA.ConvertVarchar2(p_dayend_date);
l_result := sys.UTL_DBWS.invoke (
call_handle => l_call,
input_params => l_input_params);
sys.UTL_DBWS.release_call (call_handle => l_call);
sys.UTL_DBWS.release_service (service_handle => l_service);
EXCEPTION WHEN OTHERS THEN
PKG_IRIS_SH.PRC_ins_spm('WEB','9999', 'Web Service', TO_DATE(p_dayend_date ,'DD/MM/YYYY HH24:MI:SS') ,'Error Description:' ||SQLERRM , '0');
End ;
Can any body advise on this issue.
thanks,
Ram
