<project name="Generic Webapp" default="compile" basedir=".">

<!--
        This is a generic build.xml file for Ant that can be used to develop
        any web application that conforms to the following requirements:

        - Web sources appear in the directory specified by the "webapp.web"
          property, in exactly the hierarchy to be present in the created
          web application archive.

        - Java sources (if any) appear in the directory specified by the
          "webapp.src" property, which will be compiled into the
          "WEB-INF/classes" directory of the resulting web application.

        - You must specify a "servlet.jar" property that defines the path
          of the servlet API classes you will compile against.

        - If you want to copy Struts libraries and TLD files to your web
          application, set the "struts.libs" property to the pathname of a
          directory containing struts.jar and the associated *.tld files.

        - If you want to copy additional JAR files into the WEB-INF/lib
          directory of your web app, set the "webapp.libs" property to the
          pathname of a directory containing the JAR files to be copied.

-->


<!-- ========== Prerequisite Properties =================================== -->

<!--
        These properties MUST be set on the "ant" command line, the "antrc"
        properties file in your home directory, or from settings in a superior
        build.xml script, if you wish to take advantage of the corresponding
        functionality.

        compile.classpath             The class path containing external
                                      JAR files and directories required for
                                      compiling this web application.  Note
                                      that struts.jar will automatically be
                                      added if "struts.lib" is defined, and
                                      dependent JAR files will be added if
                                      "webapp.libs" is defined.

        build.home                    Base directory into which we are building
                                      the Struts components.


        servlet.jar                   MUST be set to the pathname of the
                                      servlet API classes you wish to
                                      compile against.

        struts.libs                   If specified, must be the pathname of a
                                      directory from which "struts.jar" will be
                                      copied to your WEB-INF/lib directory, and
                                      from which all TLD files will be copied
                                      to your WEB-INF directory.  Also, the
                                      struts.jar file will automatically be
                                      added to your compile classpath.

        webapp.libs                   If specified, must be the pathname of a
                                      directory from which all available
                                      "*.jar" files are copied to the web
                                      application's WEB-INF/lib directory.
                                      Also, any JAR files found here will
                                      automatically be added to your compile
                                      classpath.

        webapp.name                   MUST be set to the base name of the web
                                      application archive file that will be
                                      created for this web application.

        webapp.suppress               Set this property to an arbitrary value
                                      (such as "true") if you do NOT want the
                                      source code for your web application
                                      copied to the WEB-INF/src directory.

        webapp.war                    If specified, overrides the default name
                                      of the web application archive file to be
                                      created for this webapp.  Default value
                                      is "struts-${webapp.name}.war".
