Maximo SOAPUI error javax.xml.ws.WebServiceException

SOAPUI error while sending payload to below url (in cluster environment)

http://localhost:9080/meaweb/services/MXASSET

Error:

<faultcode>soapenv:Server</faultcode>
 <faultstring>javax.xml.ws.WebServiceException</faultstring>

Systemout log error:
CNTR0020E: EJB threw an unexpected (non-declared) exception during invocation of method "wsSecureProcessMOS" on bean "BeanId(maximoui#mboejb.jar#mosservice, null)". Exception data: java.lang.NullPointerException

Cause: This error occurs in cluster environments. MEAMDB is configured for MIF cluster and its port is 9082 in my case. But I was using UI port 9080.

Solution 1: change port in url 

http://localhost:9082/meaweb/services/MXASSET

Solution 2: This error may occur if AD is configured. If authentication is basic and userid & password is wrong, then this error occurs. Enter correct credentials.

and then send payload to it.
