The Xephyrus Data Structures Tag Library (das) provides an easy way to create and manipulate the contents of common Java data-structures such as maps and lists using JSP tags.

• 15 Oct 05: Version 1.5 Release
  Well, ok, it's a couple days early since today is really the 13th. But I'm just so excited about this release, I had to get it out to you as soon as I could!
  
  The biggest focus of this release was polishing it up and making it worthy of a non-zero major version number. In the process several improvements were made and a few bugs were exterminated.
  
  "So what's new," you ask?
  • This version is aimed at Java5 and JSP 2.0.
  • A new sort attribute was added to all containers.
  • You might have noticed the new logo. Makes it feel good.
  • Unit tests were added for all the tags. (Mockrunner⇒ made this possible.)
  • An all new usage guide with lots of examples.
  
  "And what's been fixed," you ask?
  • The internal casting of the List tag has been fixed from using the Set interface to using the Collections interface.
  • Containers that are not designated as sorted now retain their original insert ordering.
  • A bug in the file loading code was causing data to be dropped in certain so-called edge cases. Fixed that.
  • Fixed a bug in the remove tag which was dropping the output if no variable was found. This will cause a behavior change from previous versions.
  
  Since this version is written for Java5, if you're still using a stinky old version of Java, you'll need to grab an older version of das. Similarly, if you're using a JSP engine smaller than 1.4 (did I just use the 's' word???), you'll also need an older version of das.


• 19 Aug 04: Version 0.4 Release
  This release contains a few minor bug fixes and enhancements: The packaging has been "fixed" to untar into it's own dir. The conflict between das and javabean created objects has been eliminated. The set tag has been persuaded to execute JSP in it's body. New containers are now made available to the JSP engine at the start tag rather than the end tag. There is a new 'size' tag which will report the size of the container it's nested within. The TLD has been added to the jar's manifest, allowing simpler deployment. The URI convention is also now being followed.


• 12 Apr 03: Version 0.3 Release
  New in version 0.3: A 'file' attribute has been added to the container tags allowing files to be loaded. The format of the file is specific to the container: maps load property files, lists load LF-delimited files. EL has been enabled for the 'new' and 'remove' attributes of container tags. The set tag body bug has been fixed, as well as the get tag looping bug, and, yes, even the API JavaDocs are now being generated properly. The world is a better place.


• 23 Mar 03: Version 0.2 Released
  Version 0.2 is a revision based on things I noticed or discovered when I actually tried to use v0.1 for something. *(`: This version accepts body content for the 'set' and 'add' tags, lets 'set' and 'add' tolerate null values, adds a 'remove' attribute to containers, has variable-producing worker tags use 'var' instead of 'id' (containers still use 'id' because it's appropriate there), and includes some internal cleaning-up.
  


• 09 Mar 03: Version 0.1 Released
  Version 0.1 of the Xephyrus Data Structures Tag Library is ready for general consumption. This version provides two simple containers (map and list) and four simple workers (set, add, remove and get). For more information, see the Tag Reference or download it.
