Identify four valid requests in a RESTful service using JAX-RS.
The following principles encourage RESTful applications to be simple, lightweight, and fast:
* Resource identification through URI
* Uniform interface: Resources are manipulated using a fixed set of four create, read, update, delete operations: PUT, GET, POST, and DELETE. PUT creates a new resource, which can be then deleted by using DELETE. GET retrieves the current state of a resource in some representation. POST transfers a new state onto a resource. See Responding to HTTP Methods and Requests for more information.
* Self-descriptive messages
* Stateful interactions through hyperlinks
To use Active Cache features in WebLogic 12C, which three libraries are needed from the WebLogic Server installation to be deployed in WebLogic Server?
B, D: In addition to the coherence.jar file, Coherence provides a deployable shared library, coherence-web-spi.war, that contains a native plug-in to WebLogic Server's HTTP Session Management interface. Coherence also provides the active-cache-1.0.jar file which contains the classes that allow WebLogic Server to interact with Coherence.
C: The active-cache-1.0.jar is included in the WebLogic Server installation.
Which WebLogic optimization allows one non-XA resource to participate in a distributed transaction?
A customer wants to send JMS messages to a remote WebLogic server from a Java SE application over an unreliable network connection. Which feature of WebLogic JMS will enable the customer to send messages from a Java SE client to a JMS destination that is not always easily reached?
. The JMS SAF Client feature extends the JMS store-and-forward service introduced
in WebLogic Server 9.0 to standalone JMS clients. Now JMS clients can reliably send
messages to server-side JMS destinations, even when the client cannot reach a
destination (for example, due to a temporary network connection failure). While disconnected from the server, messages sent by a JMS SAF client are stored locally on
the client file system and are forwarded to server-side JMS destinations when the
client reconnects. See Reliably Sending Messages Using the JMS SAF Client.
Identify the two options that can be used to patch WebLogic Server without Incurring application downtime.
Note:
* Rolling Upgrade is the process of upgrading a running WebLogic Server cluster with a patch, maintenance pack, or minor release without shutting down the entire cluster or domain. During the rolling upgrade of a cluster, each server in the cluster is individually upgraded and restarted while the other servers in the cluster continue to host your application.
