Web Services

Business Process Execution Language or WS-BPEL lets people orchestrate tasks and activities exposed as web services. WSO2 Business Process Server and Apache ODE can execute process descriptions written in WS-BPEL. Since BPEL is structured and based on XML, it is now far easier for business users to model and execute business processes using open source graphical tools like Eclipse BPEL Designer. This tutorial describes how to create and deploy BPEL processes in WSO2 BPS using Eclipse BPEL Designer and WSO2 BPS BPEL Exporter Eclipse Plugin.

Stored procedure is a powerful mechanism to interact with a relational database. It allows business logic to be embedded inside database as an API. Stored procedure is stored in a pre-compiled format within the database itself resulting in faster execution speed.

WSO2 Carbon Registry Kernel contains three main partitions of the Registry space. Those are namely Local Data Repository, Configuration Registry and Governance Registry.

Modern browsers protect against release of private information to a third (possibly malicious) party by imposing "cross-site scripting" or "XSS" restrictions. The basic attack is that a browser is pointed to a web site that is trusted (to some degree) by the user. In using the web site the user may provide some confidential information to that web site, such as a password, bank account number, or some other information that could be exploited by a malicious entity. Naturally, the user would hesitate to provide this information to a site that he doesn't trust (the user can be fooled through a set of techniques known as phishing, but that's a different story.) Here we assume that the user has gone to a site that is authentic.

A web services stack written in C/C++ can provide much better performance in comparison to stacks implemented in other languages due to native code. Therefore when high performance is required in web services interactions, often a C/C++ web services stack offers a much better solution. In order to quantify the performance advantage offered by WSF/C++ (WSO2 Web Service Framework for C++). we carried out a simple performance test. The article explains the procedure followed for the performance comparison and the results.

In this article, Amila Suriyaarachchi, Senior Software Engineer at WSO2, explains about auto scaling web services on Amazon EC2 cloud. Many web applications including eBanking, eCommers and eGovenance subjected to large fluctuation load. Some of these loads are predictable. For an example if there is a new campaign, a high load can be expected for that period. Further some load can be seasonal.
