+ Building The Apache Tomcat 6.0 Servlet/JSP Container
+ ====================================================
+
+This subproject contains the source code for Tomcat 6.0, a container that
+implements the Servlet 2.5 and JSP 2.1 specifications from the Java
+Community Process <http://www.jcp.org/>.
+
+Note: If you just need to run Apache Tomcat, it is not necessary to build
+it. You may simply download a binary distribution. It is cross-platform.
+Read RUNNING.txt for the instruction on how to run it.
+
+In order to build a binary distribution version of Apache Tomcat from a
+source distribution, do the following:
+
+
+(0) Download and Install a Java Development Kit
+
+* If the JDK is already installed, skip to (1).
+
+* Download a Java Development Kit (JDK) of Java SE version 5 from
+
+ http://www.oracle.com/technetwork/java/javase/downloads/index.html
+ or from another JDK vendor.
+
+ Note regarding versions of Java later than Java SE 5:
+
+ As documented elsewhere, one of components in Apache Tomcat includes
+ a private copy of the Apache Commons DBCP library. The source code
+ for this library is downloaded, processed by the build script
+ (renaming the packages) and compiled.
+
+ Due to changes in JDBC interfaces implemented by the library between
+ versions of Java SE specification, the library has to target specific
+ version of Java and can be compiled only with the JDK version
+ implementing this version of specification.
+
+ See Apache Commons DBCP project web site for more details on
+ available versions of the library and its requirements,
+
+ http://commons.apache.org/dbcp/
+
+ It is possible to use later versions of JDK to build Tomcat 6.0, but the
+ building of that component (tomcat-dbcp.jar) will be skipped and a
+ warning will be printed.
+
+* Install the JDK according to the instructions included with the release.
+
+* Set an environment variable JAVA_HOME to the pathname of the directory
+ into which you installed the JDK release.
+
+
+(1) Install Apache Ant 1.6.x on your computer
+
+* If Apache Ant 1.6.x is already installed on your computer, skip to (2).
+
+* Download a binary distribution of Ant 1.6.x from:
+
+ http://ant.apache.org/bindownload.cgi
+
+* Unpack the binary distribution into a convenient location so that the
+ Ant release resides in its own directory (conventionally named
+ "apache-ant-[version]"). For the purposes of the remainder of this document,
+ the symbolic name "${ant.home}" is used to refer to the full pathname of
+ the release directory.
+
+* Create an ANT_HOME environment variable to point the directory
+ ${ant.home}.
+
+* Modify the PATH environment variable to include the directory
+ ${ant.home}/bin in its list. This makes the "ant" command line script
+ available, which will be used to actually perform the build.
+
+
+(2) Building Tomcat 6.0
+
+(2.1) Checkout or obtain the source code for Tomcat 6.0
+
+* Tomcat 6.0 SVN repository URL:
+ http://svn.apache.org/repos/asf/tomcat/tc6.0.x/trunk/
+
+* Download a source package from:
+ http://tomcat.apache.org/download-60.cgi
+
+* Checkout the source using SVN, selecting a tag for released version or
+ trunk for the current development code, or unpack a source package. The
+ location where the source has been placed will be referred as
+ ${tomcat.source}.
+
+(2.2) Building
+
+* Go to that directory, and do:
+
+ cd ${tomcat.source}
+ ant download
+ ant
+
+* WARNING: Running "ant download" command will download libraries required
+ to build Tomcat to the /usr/share/java directory. On a typical Linux or
+ MacOX system an ordinary user will not have access to write to this
+ directory, and, even if you do, it may not be appropriate for you to
+ write there.
+
+ On Windows this usually corresponds to the "C:\usr\share\java"
+ directory, unless Cygwin is used. Read below to learn how to customize
+ the directory used to download the binaries.
+
+* NOTE: Users accessing the Internet through a proxy must use a properties
+ file to indicate to Ant the proxy configuration. Read below.
+
+* The build can be controlled by creating a ${tomcat.source}/build.properties
+ file, and adding the following content to it:
+
+ # ----- Proxy setup -----
+ # Uncomment if using a proxy server
+ #proxy.host=proxy.domain
+ #proxy.port=8080
+ #proxy.use=on
+
+ # ----- Default Base Path for Dependent Packages -----
+ # Replace this path with the directory path where dependencies binaries
+ # should be downloaded
+ base.path=/home/me/some-place-to-download-to
+
+
+(3) Updating sources
+
+It is recommended that you regularly update the downloaded Tomcat 6 sources
+using your SVN client.
+
+(4) Rebuilds
+
+For a quick rebuild of only modified code you can use:
+
+ cd ${tomcat.source}
+ ant
+
+(5) Building the servlet and jsp API documentation
+
+ cd ${tomcat.source}
+ ant -f dist.xml dist-javadoc
+
+(6) Building the extras (commons-logging, webservices etc.).
+
+ cd ${tomcat.source}
+ ant -f extras.xml
+
+(7) Building a release:
+
+ cd ${tomcat.source}
+ ant -f dist.xml release
