The following code uses the the UDDI4J library to authenticate to UDDI and gain access to the UDDI registry:

 import org.uddi4j.client.UDDIProxy;import org.uddi4j.response.AuthToken;private AuthToken accessUDDI(){ UDDIProxy uddiProxy = new UDDIProxy(); //Create an instance of UDDIProxy AuthToken token = new AuthToken(); //Create an instance of AuthToken try{  uddiProxy.setInquiryURL(UDDI_INQUIRY_URL); //Set the inquiry URL to UDDIProxy  uddiProxy.setPublishURL(UDDI_PUBLISH_URL); //Set the publish URL to UDDIProxy  //Authenticating with username and password. Successful auth returns AuthToken object.  token = uddiProxy.get_authToken(UDDI_USER,UDDI_PASSWORD);  }catch(java.net.MalformedURLException ex){ //Error setting properties) }catch(Exception e){//Error authenticating with USER and PASSWORD to UDDI server } return token;}
