• Question 23:

  A Java client, running behind a firewall, needs to connect to a UDDI registry that is deployed outside the firewall. The client is using the Java EE 5 implementation of JAXR. The client creates a set of properties that specify the proxy host and port information for the network in which the client is running. What are the remaining steps required by the JAXR client to connect to the UDDI registry?

  A. assign the properties to a connection factory and create the connection

  B. specify the URL of the UDDI registry in the properties, assign the properties to a connection factory, and create the connection

  C. specify the URL of the UDDI registry in the properties, assign the properties to a connection factory, assign the properties to a service binding, and create the connection

  D. specify the URL for the UDDI registry and the tModel in the properties, specify the search criteria for services, assign the properties to a service binding, and create the connection

  Correct Answer: B

• Question 24:
