While it might seem to be a minor design detail, it has a significant impact on the generated JAX-RPC Java code.

a. Again, like the story in the RPC (Russian Primary Chronicle), the ground for such a step must have been carefully prepared.

The RPC-style integration uses WSDL to take a "regular" method call and abstract it out to SOAP.

Bottom line, if messaging is slow, it is because your network is slow, in which case RPC would also be slow or would not work at all.

First, RPC is now able to use the exact same plugins on both the client and server tiers promoting reuse and reducing maintenance.

JAX-RPC also made some assumptions about the direction of Web services development that turned out to be wrong.

As part of this process the company was keen to update its packaging, and turned to RPC Oakham to provide a new twist on the existing style.

Typically, this encoding is intended to be used in an application like a remote procedure call (RPC).

In practice, it's mostly Java programmers who are using SOAP anyway, so it's back to the original question of whether to use RPC or RMI.

One of the beauties of JAX-RPC for the client is its ability to associate context information with an endpoint's remote method call.

As suggested by the name, the intent was to support RPC (Remote Procedure Call) operations using XML.

XML-RPC is the realization of this idea: it is nothing more than ordinary RPC, but with XML -- instead of XDR -- as the encoding format.

This schema fits into a document-style WSDL but is not well suited for RPC style since there is no global level type defined.

JAX-RPC specifies extensible type mapping support for an extended set of XML and Java types.

One final consideration when choosing between document and RPC messaging is the amount of information that may need to be handled.

Otherwise, a schema component can be defined as a type for an RPC binding.

In its present form, JAX-RPC does not help, but as this tip demonstrates you can work around those limitations.

When an object that supports this interface is the root of a serialization graph, SOAP is produced in RPC format.

For one, it was designed around the JAX-RPC 1. 0 standard, which heavily constrained the Axis architecture and limited its flexibility.

This remote call by the client to the server has its roots in Remote Procedure Call (RPC) protocol, which has been around since the 1980s.

This allows the traffic to traverse network firewalls without requiring RPC ports to be opened.

GWT abstracts this communication process behind its own remote procedure call (RPC) mechanism.

These both rely on the Remote Procedure Call (RPC) protocol to share information across the network.

Specifically, the high write latency causes the RPC latency to increase, which leads to a slower client experience.

This is the sort of information defines an API to the XML-RPC listener.

Note that the semantics of context information is not mandated by the JAX-RPC specification.

The JAX-RPC Call interface supports the dynamic invocation of a web services' operations.

Increasing either the user load or the replication distance will result in an increase of the average of RPC latency.

An alternative to the XML-based protocols is CORBA, an object-based RPC mechanism that uses its own protocol, IIOP.
