/**
 * This interceptor allows to use generic client in order to call a spring webservice.
 * It can manage each interface which respects those rules :
 * 
 * Only one parameter *Request generated by JAXB using an XSD file. This object contains all information needed by the service
 * A return object *Response generated by JAXB using an XSD file
 * 
 * If it doesn't match, a {@link net.sf.itcb.common.client.exceptions.ClientItcbException} is thrown with {@link net.sf.itcb.common.client.exceptions.ClientExceptionMappingErrors#}.
 *
 * If a {@link org.springframework.ws.soap.security.wss4j.Wss4jSecurityInterceptor} interceptor is declared in the webServiceTemplate property, 
 * then the securementCredentialsProvider (@see net.sf.itcb.common.client.security.provider.SecurementCredentialsProvider.SecurementCredentialsProvider} property has to be defined too.
 * If not, a {@link net.sf.itcb.common.client.exceptions.ClientItcbException.ClientItcbException} is thrown with {@link net.sf.itcb.common.client.exceptions.ClientExceptionMappingErrors#COMMON_CLIENT_NOT_SET_SECUREMENT_PROVIDER}.
