Service Invocation Interface is the interface which workflow engine uses to communicate with external application procedures. Analyzed the difficulties caused by diversity of external network resources to realize service invocation interface, took the description, search and evaluation of these resources into consideration, put forward an integrated service invocation strategy based on SOA stru...

Remote Method Invocation (RMI) is available in the current Java language design and implementation, providing the much-needed capability of allowing objects running in different Java processes to collaborate using a variation on the popular Remote Procedure Call (RPC). Although RMI provides features which are desirable for high-performance distributed computing, its design and implementation ar...

In order to achieve Separation of Concerns in the domain of remote method invocation, a small functional adapter is added atop Java RMI, eliminating the need for every remote object to implement java.rmi.Remote and making it possible to remotely access existing code, unchanged. The Remotemonad is introduced, and its implementation and usage are detailed. Reusing the existing, proven technology ...

In current Java implementations, Remote Method Invocation is slow. On a Pentium Pro/Myrinet cluster, for example, a null RMI takes 1228 μs using Sun’s JDK 1.1.4. This paper describes Manta, a Java system designed to support efficient communication. On the same Myrinet cluster, Manta achieves a null RMI latency of 35 μs. Manta is based on a native Java compiler. It achieves high communication pe...

Asynchronous invocations are needed in the context of distributed object frameworks to prevent clients from blocking during remote invocations. Popular Web Service frameworks offer only synchronous invocations (over HTTP). An alternative are messaging protocols but these implement a different communication paradigm. When client asynchrony is not supported, client developers have to build asynch...

IP Multimedia Subsystem (IMS) is considered to provide multimedia services to users through an IP-based control plane. The current IMS service invocation mechanism, however , requires the Serving-Call Session Control Function (S-CSCF) invokes each Application Server (AS) sequentially to perform service subscription profile, which results in the heavy load of the S-CSCF and the long session setu...

tradition has primary importance in modern arabic poetry, and invoking traditional elements is a remarkably invaluable poetic source. tradition has many resources among which literary tradition is a rich storehouseon whichpoets deeply rely. literary tradition contains many elements among which poetic figures are probably the most influential and inspirational. this article attempts to study the...

Initially, Web services had to do with communication between executables via ubiquitous Internet protocols and technologies. But in the meantime, Web services are used as virtualization layer for any kind of executables, both within an enterprise as well as across enterprises. As a consequence, any kind of protocol and communication technology must be supported to allow users to stay in the Web...
