  Log:
  Initial release notes document for the next beta, including the fixes
  and improvements that Glenn has already checked in.
  
  It would help a lot at release time if committers would update this
  document as well when adding new features or patching bugs.  :-)

  ============
  INTRODUCTION:
  ============
  
  
  This document describes the changes that have been made in the current
  beta release of Apache Tomcat, relative to the previous release.
  
  Bug reports should be entered at the interim bug reporting system for
  Jakarta projects at:
  
          http://nagoya.apache.org/bugzilla/
  
  Please use project codes "Catalina" and "Jasper" for servlet-related and
  JSP-related bug reports, respectively.
  
  
  ============
  NEW FEATURES:
  ============
  
  
  ---------------------
  Catalina New Features:
  ---------------------
  
  
  -------------------
  Jasper New Features:
  -------------------
  
  
  --------------------
  Webapps New Features:
  --------------------
  
  
  ==========================
  BUG FIXES AND IMPROVEMENTS:
  ==========================
  
  
  ------------------
  Catalina Bug Fixes:
  ------------------
  
  
  Bootstrap:  Make sure bootstrap.jar has only the minimum classes it needs to
  run, and do not duplicate classes in catalina.jar.
  
  DirContextURLConnection:  Implement getPermission so that a FilePermission is
  used to enforce security rather than the default AllPermission.
  
  HttpConnector/StandardServer:  Ensure that the server socket ignores and logs
  SocketPermission AccessControlExceptions.
  
  StandardHost:  Ignore the "directory exists" exception when context startup
  tries to expand a WAR file that is already expanded.
  
  
  ----------------
  Jasper Bug Fixes:
  ----------------
  
  
  -----------------
  Webapps Bug Fixes:
  -----------------
  
  
  Manager:  Correct message format for the "list" command's response.
  
  
  ============================
  KNOWN ISSUES IN THIS RELEASE:
  ============================
  
  
  ------------------------------------------
  Redeploying From a Web Application Archive:
  ------------------------------------------
  
  If you attempt to undeploy, then redeploy, an application from the same
  web application archive file URL (where the URL refers to an actual WAR
  file, not to a directory), the redeploy will fail with error "zip file is
  closed".  There appears to be a problem in the JDK's JarURLConnection class
  where JAR files are cached, even after they are closed, so that a request
  for a connection to the same URL returns the previous JarFile object instead
  of a new one.  As a workaround, you should do one of the following:
  * Change the URL of the web application archive each time you redeploy.
  * Deploy from an unpacked directory (on the same server) instead of from
    a WAR file (this is often more convenient in a development environment
    anyway).
  
  
  --------------------------
  Tomcat 4.0 and XML Parsers:
  --------------------------
  
  Previous versions of Tomcat 4.0 exposed the XML parser used by Jasper (the
  JAXP/1.1 reference implementation) to web applications.  This is no longer
  the case, because Jasper loads its parser with a new class loader instead.
  Keep the following points in mind when considering how to use XML parsers
  in Tomcat 4.0 and your web applications:
  
  * If you wish to make the JAXP/1.1 RI XML parser available to all web
    applications, simply move the "jaxp.jar" and "crimson.jar" files from
    the "$TOMCAT_HOME/jasper" directory to the "$TOMCAT_HOME/lib" directory.
  
  * If you wish to make another XML parser that is JAXP/1.1-compatible
    available to all web applications, install that parser into the
    "$TOMCAT_HOME/lib" directory and remove "jaxp.jar" and "crimson.jar"
    from the "$TOMCAT_HOME/jasper" directory.  It has been reported that
    Xerces 1.3.1 can be used in this fashion, but 2.x alpha releases
    can not be.
  
  * If you wish to use an XML parser (such as Xerces) in the WEB-INF/lib
    directory of your web application, this should now be possible, because
    of the modified JAXP 1.1 parser mentioned below.
  
  WARNING:  Tomcat 4.0 now ships with a modified version of the JAXP/1.1
  (Final) "jaxp.jar" and "crimson.jar" files in the "jasper" subdirectory.
  The "sealed" attribute has been removed from the manifest file for these
  two JARs, to avoid "package sealing violation" errors that were caused by
  them in a JDK 1.3 environment.  You MUST NOT replace these files with a
  different (or later) release of JAXP, unless that later release has had
  the sealed attribute removed, or you will encounter "package sealing violation"
  errors when trying to use a different XML parser in a web application.
