Apache upgrades Tomcat Web server

Version 7.0 boasts Java specification compliance, memory leak detection

Apache Tomcat 7.0, the latest version of the popular open source Java Web server, is available Tuesday from the Apache Software Foundation.

The upgrade constitutes the first major release of the project since 2006. To ease Web framework integration, version 7.0 implements the Java Servlet 3.0, JavaServer Pages 2.2 and Expression Language 2.2 specifications.

Also, memory leak detection has been improved in version 7.0. "That functionality will help developers avoid problems in the [Java Virtual Machine] and the third-party libraries they might be using that can often trigger [memory leaks] on application reloads," said Mark Thomas, a member of the Tomcat project management committee at Apache.

Tomcat, Thomas said, offers the benefit of being lightweight and it gets the job done.  "It does what developers want it to do, and it does it reliably. They want it to run their Web applications," he said.

Tomcat 7.0 simplifies writing and deploying of complex Web applications, offering out-of-the-box support for development features that would otherwise require manual coding, the foundation said.

Introduced 10 years ago, Apache Tomcat has been downloaded more than 10 million times, Apache said. It forms the basis of commercial products from such companies as MuleSoft and the SpringSource unit of VMware, Thomas said.

Version 7.0 is offered under the Apache Software License v2.0 at the Tomcat Web page.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.
