If we use these bpel functions, at runtime, we might get the following error
TypeError: Cannot find function <name> in object http://docs.oasis-open.org/wsbpel/2.0/process/executable
To overcome the error, open the bpel component in source mode, look for namespace prefix “bpel”.
Change it to any other name. Search for any code using this prefix, make modification in all those places also.
