Could not handle mustUnderstand headers: {http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd}Security. Returning fault

Question

I went through links like: SOAPFaultException "MustUnderstand headers (oasis-200401-wss-wssecurity-secext-1.0.xsd) are not understood", but still struggling.

Answer 1

I was able to find the solution looking at https://docs.spring.io/spring-ws/site/apidocs/org/springframework/ws/soap/security/wss4j/Wss4jSecurityInterceptor.html and https://memorynotfound.com/spring-ws-username-password-authentication-wss4j/.

I simply used below bean and its started working fine.

@Bean
public Wss4jSecurityInterceptor securityInterceptor() {
  Wss4jSecurityInterceptor security = new Wss4jSecurityInterceptor();
  security.setSecurementActions("NoSecurity");
  security.setSecurementPasswordType(WSConstants.PW_TEXT);
  return security;
}
