What is a RPC handler?

What is a RPC handler?

Client-Side JAX-RPC Handlers. On the Web service client, JAX-RPC handlers can intercept and process messages sent from a client application and the corresponding message returned by the service. These handlers can, for example, process the SOAP message.

What is JAX-RPC used for?

Essentially, JAX-RPC enables clients to access a web service as if the web service was a local object mapped into the client’s address space even though the web service provider is located in another part of the world. The JAX-RPC is done by using the XML-based protocol SOAP, which typically rides on HTTP.

What is defined by JAX-RPC specifications?

JAX-RPC is a specification that defines the Java APIs for making XML-based remote procedure calls (RPC). In particular, these APIs are used to invoke and get a response from a web service using SOAP 1.1, and XML-based protocol for exchange of information in a decentralized and distributed environment.

What is the equivalent of JAX-RPC service endpoint interface in WSDL file?

JAX-RPC Web Services Using a WSDL To generate the service interface from the WSDL, use the wscompile command with -import option, passing it the location of the WSDL document. Alternatively, you can store the information required to generate the service definition interface in a configuration file by name config. xml.

What is JAX-RPC and JAX WS?

JAX-WS and JAX-RPC are Java programming APIs that are used in the web service bindings, to create and consume SOAP messages. JAX-WS is the successor to JAX-RPC. Using the web service binding, you can specify that messages are processed by handlers.

What is JAX WS handler?

Java™ API for XML Web Services (JAX-WS) provides you with a standard way of developing interoperable and portable web services. Use JAX-WS handlers to customize web services requests or response handling.

How do you get the SOAP header in JAX WS?

You can read the soap header from the SOAPMessageContext in a SOAPHandler class, then pass the values to your @WebService implementation via attributes in the MessageContext .

How are JAX-RPC clients used in an application?

JAX-RPC clients are applications that use the JAX-RPC APIs and runtime for invoking a Web service. These clients import the service using WSDL and can invoke a service that has been defined and deployed on a non-Java platform.

Which is WebLogic Server implements the JAX-RPC specification?

The Java API for XML based RPC (JAX-RPC) is a specification that defines the APIs used to invoke a web service. WebLogic Server implements the JAX-RPC specification. The following table briefly describes the core JAX-RPC interfaces and classes. Main client interface. Factory class for creating Service instances.

How are SOAP messages used in JAX-RPC?

For more information on SOAP messages, see SOAP Messages. JAX-RPC uses technologies HTTP, SOAP, and the WSDL defined by the World Wide Web Consortium (W3C), which makes it possible for a JAX-RPC client to access a Web service that is not running on the Java platform and vice versa.

Which is Java API for XML based RPC?

The Java API for XML based RPC (JAX-RPC) is a specification that defines the APIs used to invoke a web service. WebLogic Server implements the JAX-RPC specification.
