WAG Applications provides a collection of WAG-hosted Web applications.
WAG Applications is a collection of Web applications that are capable of being hosted by the Web Application Gateway.
WAG provides core functionality such as user definition, authentication, and administration, for all hosted Web applications.
Enhancements:
- Added application specific handlers to the wagErrorHandler function.
- Added is_email() function to functions.php which checks if a a given e-mail address is valid. It checks for all top level domains including the new ones (.biz, .info, .museum etc.) and the special ones (.arpa, .int etc.) as well as with e-mail addresses based on IPs (e.g. webmaster@123.45.123.45). (Function derived from PHP user contributed notes.)
- Enhanced the error reporting for both WAG and application database errors to include the server name and user name/id. This will help admins target problems if they are responsible for multiple WAG installations.
- Added "Date Added" and "Date Last Login" information to Administration > Users screen.
- Made style sheet changes related to form field fonts.
- Bug Fixes
- Validation of user e-mail addresses was not performed correctly and causing any valid e-mail address to be flagged as invalid.
- When admin changes a users password, the e-mail password, if configured, is also changed. This allows the admin to "lockout" a user from both WAG and e-mail if needed.

Realtime Application Interface project allows applications with strict timing constraints to be run on Linux.
A real time system is able to guarantee the timing requirements of the processes under its control.

Enhancements:
- Improvements were made to netrpc.
- Context switching between hard and soft real-time, handling of TSC errors, and POSIX compatibility have been improved.
- There are numerous minor bugfixes.

IBM 3270 Terminal Applications suite consists of seven applications.
x3270 is an IBM 3270 terminal emulator for the X Window System and Windows. The project runs on most Unix-like operating systems -- e.g., Linux, Mac OS X, Solaris and Cygwin. It also runs natively on Windows.
x3270 runs over a TELNET connection, emulating either an IBM 3279 (color) or 3278 (monochrome). It supports:
- The full TN3270E protocol
- SSL/TLS (via the OpenSSL library) for encrypted sessions
- APL2 characters
- Non-English character sets, including Russian, Turkish, Hebrew and DBCS Chinese and Japanese
- IND$FILE file transfer
- NVT mode (emulating a color xterm)
- A pop-up keypad for 3270-specific keys
- A scrollbar
- Printer session integration
- Extensive debugging and scripting facilities
It does not yet support graphics. x3270 is distributed as source code, and can be used for free.
- x3270 is available in several different forms:
- x3270 is for use on an X graphics display
- c3270 is a curses-based version for use on a dumb terminal (e.g., a serial terminal or a Linux console)
- wc3270 is the Windows console version of c3270
- s3270 is a displayless version for writing screen-scraping scripts
- tcl3270 is similar to s3270, but integrated with Tcl
- pr3287 is for printer emulation
- wpr3287 is the native Windows version of pr3287
Also available is x026, an IBM 026 Keypunch emulator.
Enhancements:
- Proxy support was added.
- 3270 background color was added to c3270 and wc3270.
- Numerous small bugs were fixed.

php.MVC implements the Model-View-Controller design pattern, and encourages application design based on the Model 2 paradigm. This design model allows the Web page or other contents (View) to be mostly separated from the internal application code (Controller/Model), making it easier for designers and programmers to focus on their respective areas of expertise.
The framework provides a single entry point Controller. The Controller is responsible for allocating HTTP requests to the appropriate Action handler (Model) based on configuration mappings.
The Model contains the business logic for the application. The Controller then forwards the request to the appropriate View component, which is usually implemented using a combination of HTML with PHP tags in the form of templates. The resulting contents are returned to the client browser, or via another protocol such as SMTP.
php.MVC is a PHP port of Jakarta Struts. It currently supports many features of Struts, including declarative application configuration via the XML digester. For example, mappings from the various Action business logic components to appropriate results pages can be specified declaratively in the XML configuration file.
Main features:
- Free OpenSource software: This gives users full control of the software, and the able to modify the source code to suit specific needs.
- Security: php.MVC applications have only one entry point (per application). This makes it easy to protect sensitive application code and data.
- Flexible Installation: Individual php.MVC applications can be installed outside of the main php.MVC library directory tree.
- Multi-applications: There is no limit to the number of applications per php.MVC installation.
- Object Oriented design (OOD). The php.MVC framework is based on OOD principles, making it more extendable and maintainable.
- Database integration: The php.MVC framework ships with the Pear::DB Database Abstraction Layer, and a driver for the MySQL relational database manager (RDBM) is provided.
- Action Chaining: php.MVC allows for passing control to other Actions. This makes it easy to process a sequence of Actions (business logic classes) and static resources (pages).
- XML configuration: php.MVC uses declarative application configurations using Extensible Markup Language (XML) files. Each application has its own XML configuration file.
- MVC Model 2 design: php.MVC implements the Model-View-Controller (MVC) Model 2 design pattern. The Model 2 paradigm allows the separation of the application presentation from the business logic, making it easier for designers and programmers to focus on their respective areas of expertise.
- Form button mapping: php.MVC implements the LookupDispatchAction class to enable HTML form buttons to be mapped to particular business logic methods. For example, a form submit button called "Add to Cart" could be mapped to an Action class method called MyCartAction->addToCart(...).
- Message Resources: php.MVC provides a PropertyMessageResources class that handles messages in text string properties files with parametric replacement. This can provide Locale-sensitive messages for internationalized applications.
- The php.MVC framework is based on Jakarta Struts application framework design. Struts has proven to be reliable, extendable and well supported.
Enhancements:
- This development release adds bugfixes and enhancements to the framework, a compressed performance version for use in more demanding hosting environments, and an example application to demonstrate the use of both versions.

Albatross library is a small and flexible Python toolkit for developing highly stateful web applications.
The toolkit has been designed to take a lot of the pain out of constructing intranet applications although you can also use Albatross for deploying publicly accessed web applications.
In slightly less than 2600 lines of Python (according to pycount), you get the following:
An extensible HTML templating system similar to DTML that promotes separation of presentation and implementation for improved program maintainability. The templating system includes tags for:
- Conditional processing,
- Macro definition and expansion,
- Sequence iteration and pagination,
- Tree browsing,
Lookup tables to translate Python values to arbitrary template text. The ability to place Python code for each page in a dynamically loaded module, or to place each page in its own class in a single mainline.
Optional sessions, which can be either:
- Browser based sessions via automatically generated hidden form fields (cryptographically signed to ensure integrity),
- Server-side sessions via a supplied TCP session server,
- Server-side file based session store.
Applications that can be deployed as either CGI programs or as mod_python module with minor changes to program mainline. Custom deployment can be achieved by developing your own Request class.
Over 120 pages of documentation including many installable samples. A primary design goal of Albatross is that it be small and easy to use and extend. The toolkit application functionality is defined by a collection of fine grained mixin classes. Eight different application types and four different execution contexts are prepackaged, allowing you to define your own drop in replacements for any of the mixins to alter any aspect of the toolkit semantics.
Object Craft developed Albatross because there was nothing available with the same capabilities which they could use for consulting work. For this reason the toolkit is important to Object Craft and so is actively maintained and developed.
Albatross is licensed under a liberal BSD open-source license.
Enhancements:
- Improvements and fixes were made to < al-for >, < al-macro >, < al-option >, NameRecorderMixin, and the FastCGI driver.
