Projects / Aejaks


Aejaks is a windowing toolkit for rapid development of AJAX-enabled Web applications. It combines the powerful simplicity of the Tcl language with the Java-based Echo2 browser-independent windowing system. Aejaks applications are written in a single scripting language, without need to write any HTML, Javascript, or CSS. It borrows from the Tk windowing system, but is not directly compatible with Tk. It runs on top of any Java Web server, and can make use of any existing Java library.

Recent releases

  •  27 Sep 2013 02:52

    Release Notes: Fixes bugs in the MrPersister library DbObjBuilder procedure where BLOB datatypes were not mapped correctly to a Java object. The ImageReference class constructor was fixed to allow java.awt.Image objects to be built correctly. The embedded JTcl interpreter was upgraded to version 2.6.0.

    •  17 Oct 2012 20:14

      Release Notes: This release fixes a bug in the MrPersister library which caused a SQL BOOLEAN datatype not to be mapped correctly to a Boolean Java type. The included JTcl interpreter has been upgraded to fix a possible memory leak. The H2 database engine has been upgraded to a recent version.

      •  20 Dec 2011 21:12

        Release Notes: This release replaces the Jacl interpreter with JTcl, an updated verson of Tcl for Java. JTcl implements nearly all Tcl 8.4 features. Community-supported versions of Echo2 and related libraries are included, which fixes compatibility issues with Internet Explorer 9. Also fixed in this release is the updateOptimistic method in the MrPersister package. Window object (".") now has a getClientProperties method. The H2 database has been upgraded to a recent version (see the CHANGES file for upgrade information).

        •  06 Oct 2010 02:40

          Release Notes: The ExpandableSection widget now has methods to set title foreground and background colors. The WarMachine sample program was enhanced to allow additional JAR library files. The Window method exitApp can now use a logout servlet to exit an application. Bugs fixed include the removing extraneous characters in the hyde package. The ComboBox widget was fixed to avoid backslash quoting of whitespace characters. The library procedure aejaks_entryBox has been changed so that the callback now passes two arguments; this change is incompatible with previous versions and will require a code change.

          •  23 Apr 2009 03:37

            Release Notes: Some real or potential memory leaks were fixed. Other fixes and enhancements were made to runtime code, affecting the Pack command and sample programs. An 'updateOptimistic' method was added to the GenericDao object in the MrPersister database package. This allows the use of 'optimistic locking' when updating a row in order to avoid hidden updates while maintaining high concurrency. The H2 database engine was updated to the current version.
