Neotys Takes Web Load Testing to the Next Level with NeoLoad Version 2.0

Neotys, a leader in easy-to-use, cost-effective stress and load testing tools for Web applications, today announced a major new release of its flagship product, NeoLoad.
Aubagne (PRWEB) September 19, 2006 -- Neotys, a leader in easy-to-use, cost-effective stress and load testing tools for Web applications, today announced a major new release of its flagship product, NeoLoad. NeoLoad Version 2.0 delivers all the cost-effective, easy-to-use features of the original, with the addition of simplified scenario creation and improved test monitoring, analysis and reporting. NeoLoad version 2.0 also delivers optional modules, including a SOAP module for web services support and monitoring modules for dedicated platform and server monitoring.“NeoLoad Version 2.0 reaffirms our strong belief that businesses shouldn’t have to compromise quality for lower costs,” said Stephane Jammet, vice president of sales and business development, Neotys. “This new edition delivers all the capabilities of the more expensive web performance testing tools at a fraction of the price and it’s extremely easy to use. In a matter of minutes, new NeoLoad users can design and run their first performance test and generate a comprehensive performance and scalability report.”Fast and easy scenario creation for complex applications is a hallmark of NeoLoad Version 2.0. New features specific to scenario creation include:* Wizard for automatic handling of dynamic parameters generated by the server - Eliminates labor-intensive and time-consuming manual parameterization * Enhanced .Net support - Automates the detection and management of .NET parameters Viewstate and Eventvalidation* Advanced scenario customization - Advanced tools for scenario parameterization make each scenario as realistic as possible without any scripting and no programming language required* Multiple authentication wizard - Enables the definition and use of different account profiles to log into secured applications while a test is in progress“NeoLoad was chosen as our load generation tool after an exhaustive search that included free open source products and very expensive top-of-the-line load solutions,” said Josh Schlesser, vice president of technology, The Active Network. “It was clear almost immediately that we’d made a very wise decision choosing NeoLoad. The product saves us significant time over open source solutions and we soon realized that we really didn’t need all the features in the more expensive tools. The advances in NeoLoad Version 2.0 reflect the practical features we’ve come to expect from Neotys and we’re eager to begin running it as soon as possible.”In addition to advanced scenario creation, NeoLoad Version 2.0 also delivers improved live monitoring features and new powerful graphs for more in-depth analysis as well as nine new optional modules — including a SOAP module for web services support and several modules for dedicated platform and server monitoring. The SOAP module enables the design of SOAP requests from a WSDL file or manually from a specific interface and is the industry’s most cost-effective tool for testing the robustness of SOA architectures. The platform and server monitoring modules are specifically dedicated to remote server monitoring. An agentless design ensures hassle-free installation of any program on the monitored servers. Performance counters such as CPU usage, network bandwidth and active connections pool size are collected while the test is running – making it easy to track any performance concerns. Dedicated monitoring modules support numerous environments, including Windows, HTTP, Apache, Linux, Solaris, RSTAT, SNMP, WebLogic and WebSphere.

Canoo Releases Free Open Source XML Tool for Java RIA Development

Basel (PRWEB) September 19, 2006 -- Canoo is proud to announce the release of ULC XML, a tool that allows developers to create UltraLightClient user interfaces from XML files. ULC XML is a free and open-source tool for Canoo’s Java RIA library. It is available for download at the ULC XML project site (https://ulcxml.dev.java.net/) at Java.net.About ULC XMLULC XML is an UI generator for UltraLightClient applications. The XML file is parsed at runtime and rendered into Java objects. ULC XML is similar to the solution offered by the open source project SwiXml: Java classes are mapped to element names; property names translate into attribute names. Developers familiar with SwiXml have little effort learning how to use ULC XML. The Canoo tool offers a Rich Internet Application (RIA) option for SwiXml/Swing developers. The download package includes free samples such as the ULC XML version of the ULC OnlineShop demo.ULC XML provides a faster and easier way to develop rich, responsive GUIs for web applications. The major benefit is that the layout of the user interface is separate from the Java classes of the application. The XML hierarchy mirrors the hierarchy of UI components such as windows, sub-windows, tables, trees and tabs and allows developers to quickly assemble a user interface.RequirementsULC XML requires a license of UltraLightClient. A free evaluation license is available at the product website. A developer key costs 1499 US$ per seat and can be purchased online at the Canoo webshop.Industrial Strength for Rich Internet ApplicationsUltraLightClient (http://www.canoo.com/ulc/) is a Java library that bridges the gap between Swing UI components and a server-side Java EE architecture, enabling the development of Rich Internet Applications (RIA) that are based entirely on Java.The lean library delegates everything it possibly can to the Java EE and Java SE infrastructure. It uses Swing on the client, standard communication protocols set by the Java EE container, and standard lifecycle management on the server. In contrast to other more proprietary platforms, UltraLightClient closely follows Java standards and can be easily integrated into existing web platforms.The principal design of UltraLightClient is based on the half-object and protocol design pattern. Applied to Swing, this pattern is used to offer the Swing API in a server-side programming model, providing rich user interfaces in a web architecture.UltraLightClient-based applications can be deployed in any Java EE container, as a portlet, or even stand-alone without changing the code. On the client, a standard JRE from 1.4.2 or later is all that is required.About CanooCanoo Engineering (http://www.canoo.com) is a leader in Web front-end application development and delivers Java-based software consulting services and products. It was founded in 1999 by a team of senior executives and software engineers. The company is privately held and is headquartered in Basel, Switzerland. Besides UltraLightClient, a software library for Swing-based Rich Internet Applications; the Canoo product range includes WMTrans, a software library for language analysis and generation; and Webtest, an open-source, XP-style functional testing tool for Java-based web applications.
