Subject cvs commit: jakarta-ant/src/main/org/apache/tools/ant/taskdefs/optional TraXLiaison.java
Date Wed, 03 Jan 2001 16:48:45 GMT
rubys       01/01/03 08:48:42

  Modified:    src/main/org/apache/tools/ant/taskdefs XSLTProcess.java
  Added:       src/main/org/apache/tools/ant/taskdefs/optional
                        TraXLiaison.java
  Log:
  Added a TraX liaison for the <style> task.  This enables Apache's Xalan2
  and Sun's JAXP1.1 implementations to be used.
  
  I don't expect many developers to have multiple XSLT implementations in
  their classpath, but if they do, I made the TraX liaison the default
  for several reasons:
    1) It is standard
    2) It is the most modern interface
    3) It is designed as an pluggable interface, so in theory (though perhaps
       down the road a bit), it should be the only liaison required.
