Wss4jSecurityInterceptor should be in spring-ws-security from what I see on www of maven.
What should be the issue that I am unable to import Wss4jSecurityInterceptor ?
What tells you that you are unable to do so? Post the exact error message.
in external librarias i do not see ws-security library and also when you type Wss4jSecurityInterceptor and try to import it you can not do it. you have only option to create new class "Wss4jSecurityInterceptor "
