Proprietary application servers provide system services in a well defined but proprietary manner. The application developers develop programs according to the specification of the application server. Dependence on a particular vendor is the drawback of this approach

Opposite but analogous case is the Java EE platform discussed below.

Java EE application servers provide system services in a well defined, open, industry standard. The application developers develop programs according to the Java EE specification and not according to the application server.

A Java EE application developed according to Java EE standard can be deployed in any Java EE application server making it vendor independent.

This article compares the features and functionality of application servers, grouped by the hosting environment that is offered by that particular application server.

Contents

Apache

Apache-based application server bundles integrate script languages (such as Perl, Python, PHP, Ruby, Tcl) into Apache web server.

BASIC Language

• Run BASIC [1] - An all-in-one BASIC scriptable appserver with automatic session and state management

C++ Language

• Barracuda Web Server SDK Embeddable Application Server with C and Lua support.
• Tuxedo [2] Based on the ATMI standard, is one of the original application servers.
• G-WAN [3] Global-WAN (G-WAN, 105 KB) C servlets (that you 'edit & play') are as fast as Microsoft IIS 7.0 static pages cached in the kernel.
• Tntnet [4] is a web application server for C++. Tntnet comes with a template engine, which allows the programmer to embed C++-code into HTML pages. Since these templates are not compiled at runtime, but like classic C++-programs in a separate compile-cycle, the resulting programs are native and therefore very fast. Tntnet is multithreaded and supports object lifetime through scoped variables.
• cppserv C++ servlet container
• Wt is a web toolkit similar to Qt permitting GUI-application like web development with built in Ajax capabilities.
• Wexus [5] C++ Library for Webdevelopment
• libapache2-mod-raii [6] C++ application server module for apache2

Common-Lisp Language

• Core Server [7] Common-Lisp Application Server for Linux

Haskell Language

• HAppS Application server which allows and takes advantage of functional programming.
