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. 

Error in SOAPUI - axis2ns1:Server Internal Error

Error: 
Response:
      <soapenv:Fault xmlns:axis2ns1="http://schemas.xmlsoap.org/soap/envelope/">
        <faultcode>axis2ns1:Server</faultcode>
        <faultstring>Internal Error</faultstring>
        <detail/>
      </soapenv:Fault>

Solution:
Add custom property "webservices.unify.faults" as false in websphere.

Servers > Server Types > Websphere application servers > Application Servers > MXServer > Process definition > Java Virtual Machine > Custom properties > Create new property - webservices.unify.faults = false

Save to master configuration and Restart the Application Server

Note: In cluster environment, add property to all clusters.
