java - ClassCastException of StructDescriptor on websphere but not on tomcat -

my application working fine on local tomcat server. later deployed in websphere making war file. after deployment, whenever try make call stored procedure using structdescriptor follows, getting classcastexception. following code segment:

structdescriptor projecttypedesc = structdescriptor.createdescriptor(         "fra_data.region_type", st.getconnection()); struct[] structs = new struct[filterdto.getregion().size()]; (int = 0; < filterdto.getregion().size(); ++i) {     int str = (int) filterdto.getregion().get(i).intvalue();     object[] objects = new object[] { str };     struct struct = new struct(projecttypedesc, st.getconnection(),             objects);     structs[i] = struct; } arraydescriptor arraydescriptor = arraydescriptor.createdescriptor(         "fra_data.regions", st.getconnection()); arraylist.add(new array(arraydescriptor, st.getconnection(), structs)); 

and error thrown :

the object created in data base follows:

create or replace type region_type object (region number);  create or replace type regions table of region_type; 

i tried search on different forms , didn't solution. please help.

use wscallhelper.getnativeconnection "unwrap" oracleconnection contained in wsjdbcconnection:

structdescriptor projecttypedesc = structdescriptor.createdescriptor(         "fra_data.region_type",         wscallhelper.getnativeconnection(st.getconnection()));
