This is
in relation to:-
http://stackoverflow.com/questions/2576514/basic-tomcat-servlet-error
I changed my
web.xml file, did ant compile , all, /etc/init.d/tomcat stop , start
Even then my
web.xml file
in tomcat deployment is still unchanged.
This is build.properties file:-
app.name=hello
catalina.home=/usr/local/tomcat
manager.username=admin
manager.password=admin
This is my build.xml file. Is there something wrong with this:-

General purpose build script for
web applications and
web services,
including enhanced support for deploying directly
to a Tomcat 6
based server.
This build script assumes that the source code of your
web application
is organized into the following subdirectories underneath the source
code directory from which you execute the build script:
docs Static documentation files
to be copied
to
the "docs" subdirectory of your distribution.
src Java source code (and associated resource files)
to be compiled
to the "WEB-INF/classes"
subdirectory of your
web applicaiton.
web Static HTML, JSP, and other content (such as
image files), including the WEB-INF subdirectory
and its configuration file contents.

<!-- A "project" describes a set of targets that may be requested
when Ant is executed. The "default" attribute defines the
target which is executed if no specific target is requested,
and the "basedir" attribute defines the current working directory
from which Ant executes the requested task. This is normally
set
to the current working directory.
-->
<project name="My Project" default="compile" basedir=".">
<!-- ===================== Property Definitions =========================== -->
<!--
Each of the following properties are used
in the build script.
Values for these properties are set by the first place they are
defined, from the following list:
* Definitions on the "ant" command line (ant -Dfoo=bar compile).
* Definitions from a "build.properties" file
in the top level
source directory of this application.
* Definitions from a "build.properties" file
in the developer's
home directory.
* Default definitions
in this build.xml file.
You will note below that property values can be composed based on the
contents of previously defined properties. This is a powerful technique
that helps you minimize the number of changes required when your development
environment is modified. Note that property composition is allowed within
"build.properties" files as well as
in the "build.xml" script.
-->
<property file="build.properties"/>
<property file="${user.home}/build.properties"/>
<!-- ==================== File and Directory Names ======================== -->
<!--
These properties generally define file and directory names (or paths) that
affect where the build process stores its outputs.
app.name Base name of this application, used
to
construct filenames and directories.
Defaults
to "myapp".
app.path Context path
to which this application should be
deployed (defaults
to "/" plus the value of the
"app.name" property).
app.version Version number of this iteration of the application.
build.home The directory into which the "prepare" and
"compile" targets will generate their output.
Defaults
to "build".
catalina.home The directory
in which you have installed
a binary distribution of Tomcat 6. This will
be used by the "deploy" target.
dist.home The name of the base directory
in which
distribution files are created.
Defaults
to "dist".
manager.password The login password of a user that is assigned the
"manager" role (so that he or she can execute
commands via the "/manager"
web application)
manager.url The URL of the "/manager"
web application on the
Tomcat installation
to which we will deploy
web
applications and
web services.
manager.username The login username of a user that is assigned the
"manager" role (so that he or she can execute
commands via the "/manager"
web application)
-->
<property name="app.name" value="myapp"/>
<property name="app.path" value="/${app.name}"/>
<property name="app.version" value="0.1-dev"/>
<property name="build.home" value="${basedir}/build"/>
<property name="catalina.home" value="../../../.."/> <!-- UPDATE THIS! -->
<property name="dist.home" value="${basedir}/dist"/>
<property name="docs.home" value="${basedir}/docs"/>
<property name="manager.url" value="http://localhost:8080/manager"/>
<property name="src.home" value="${basedir}/src"/>
<property name="
web.home" value="${basedir}/web"/>
<!-- ==================== External Dependencies =========================== -->
<!--
Use property values
to define the locations of external JAR files on which
your application will depend.
In general, these values will be used for
two purposes:
* Inclusion on the classpath that is passed
to the Javac compiler
* Being copied into the "/WEB-INF/lib" directory during execution
of the "deploy" target.
Because we will automatically include all of the Java classes that Tomcat 6
exposes
to web applications, we will not need
to explicitly list any of those
dependencies. You only need
to worry about external dependencies for JAR
files that you are going
to include inside your "/WEB-INF/lib" directory.
-->
<!-- Dummy external dependency -->
<!--
<property name="foo.jar"
value="/path/to/foo.jar"/>
-->
<!-- ==================== Compilation Classpath =========================== -->
<!--
Rather than relying on the CLASSPATH environment variable, Ant includes
features that makes it easy
to dynamically construct the classpath you
need for each compilation. The example below constructs the compile
classpath
to include the servlet.jar file, as well as the other components
that Tomcat makes available
to web applications automatically, plus anything
that you explicitly added.
-->
<path id="compile.classpath">
<!-- Include all JAR files that will be included
in /WEB-INF/lib -->
<!-- *** CUSTOMIZE HERE AS REQUIRED BY YOUR APPLICATION *** -->
<!--
<pathelement location="${foo.jar}"/>
-->
<!-- Include all elements that Tomcat exposes
to applications -->
<fileset dir="${catalina.home}/bin">
<include name="*.jar"/>
</fileset>
<pathelement location="${catalina.home}/lib"/>
<fileset dir="${catalina.home}/lib">
<include name="*.jar"/>
</fileset>
</path>
<!-- ================== Custom Ant Task Definitions ======================= -->
<!--
These properties define custom tasks for the Ant build tool that interact
with the "/manager"
web application installed with Tomcat 6. Before they
can be successfully utilized, you must perform the following steps:
- Copy the file "lib/catalina-ant.jar" from your Tomcat 6
installation into the "lib" directory of your Ant installation.
- Create a "build.properties" file
in your application's top-level
source directory (or your user login home directory) that defines
appropriate values for the "manager.password", "manager.url", and
"manager.username" properties described above.
For more information about the Manager
web application, and the functionality
of these tasks, see <http://localhost:8080/tomcat-docs/manager-howto.html>.
-->
<taskdef resource="org/apache/catalina/ant/catalina.tasks"
classpathref="compile.classpath"/>
<!-- ==================== Compilation Control Options ==================== -->
<!--
These properties control option settings on the Javac compiler when it
is invoked using the <javac> task.
compile.debug Should compilation include the debug option?
compile.deprecation Should compilation include the deprecation option?
compile.optimize Should compilation include the optimize option?
-->
<property name="compile.debug" value="true"/>
<property name="compile.deprecation" value="false"/>
<property name="compile.optimize" value="true"/>
<!-- ==================== All Target ====================================== -->
<!--
The "all" target is a shortcut for running the "clean" target followed
by the "compile" target,
to force a complete recompile.
-->
<target name="all" depends="clean,compile"
description="Clean build and dist directories, then compile"/>
<!-- ==================== Clean Target ==================================== -->
<!--
The "clean" target deletes any previous "build" and "dist" directory,
so that you can be ensured the application can be built from scratch.
-->
<target name="clean"
description="Delete old build and dist directories">
<delete dir="${build.home}"/>
<delete dir="${dist.home}"/>
</target>
<!-- ==================== Compile Target ================================== -->
<!--
The "compile" target transforms source files (from your "src" directory)
into object files
in the appropriate location
in the build directory.
This example assumes that you will be including your classes
in an
unpacked directory hierarchy under "/WEB-INF/classes".
-->
<target name="compile" depends="prepare"
description="Compile Java sources">
<!-- Compile Java classes as necessary -->
<mkdir dir="${build.home}/WEB-INF/classes"/>
<javac srcdir="${src.home}"
destdir="${build.home}/WEB-INF/classes"
debug="${compile.debug}"
deprecation="${compile.deprecation}"
optimize="${compile.optimize}">
<classpath refid="compile.classpath"/>
</javac>
<!-- Copy application resources -->
<copy todir="${build.home}/WEB-INF/classes">
<fileset dir="${src.home}" excludes="**/*.java"/>
</copy>
</target>
<!-- ==================== Dist Target ===================================== -->
<!--
The "dist" target creates a binary distribution of your application
in a directory structure ready
to be archived
in a tar.gz or zip file.
Note that this target depends on two others:
* "compile" so that the entire
web application (including external
dependencies) will have been assembled
* "javadoc" so that the application Javadocs will have been created
-->
<target name="dist" depends="compile,javadoc"
description="Create binary distribution">
<!-- Copy documentation subdirectories -->
<mkdir dir="${dist.home}/docs"/>
<copy todir="${dist.home}/docs">
<fileset dir="${docs.home}"/>
</copy>
<!-- Create application JAR file -->
<jar jarfile="${dist.home}/${app.name}-${app.version}.war"
basedir="${build.home}"/>
<!-- Copy additional files
to ${dist.home} as necessary -->
</target>
<!-- ==================== Install Target ================================== -->
<!--
The "install" target tells the specified Tomcat 6 installation
to dynamically
install this
web application and make it available for execution. It does
*not* cause the existence of this
web application
to be remembered across
Tomcat restarts; if you restart the server, you will need
to re-install all
this
web application.
If you have already installed this application, and simply want Tomcat
to
recognize that you have updated Java classes (or the
web.xml file), use the
"reload" target instead.
NOTE: This target will only succeed if it is run from the same server that
Tomcat is running on.
NOTE: This is the logical opposite of the "remove" target.
-->
<target name="install" depends="compile"
description="Install application
to servlet container">
<deploy url="${manager.url}"
username="${manager.username}"
password="${manager.password}"
path="${app.path}"
localWar="file://${build.home}"/>
</target>
<!-- ==================== Javadoc Target ================================== -->
<!--
The "javadoc" target creates Javadoc API documentation for the Java
classes included
in your application. Normally, this is only required
when preparing a distribution release, but is available as a separate
target
in case the developer wants
to create Javadocs independently.
-->
<target name="javadoc" depends="compile"
description="Create Javadoc API documentation">
<mkdir dir="${dist.home}/docs/api"/>
<javadoc sourcepath="${src.home}"
destdir="${dist.home}/docs/api"
packagenames="*">
<classpath refid="compile.classpath"/>
</javadoc>
</target>
<!-- ====================== List Target =================================== -->
<!--
The "list" target asks the specified Tomcat 6 installation
to list the
currently running
web applications, either loaded at startup time or
installed dynamically. It is useful
to determine whether or not the
application you are currently developing has been installed.
-->
<target name="list"
description="List installed applications on servlet container">
<list url="${manager.url}"
username="${manager.username}"
password="${manager.password}"/>
</target>
<!-- ==================== Prepare Target ================================== -->
<!--
The "prepare" target is used
to create the "build" destination directory,
and copy the static contents of your
web application
to it. If you need
to copy static files from external dependencies, you can customize the
contents of this task.
Normally, this task is executed indirectly when needed.
-->
<target name="prepare">
<!-- Create build directories as needed -->
<mkdir dir="${build.home}"/>
<mkdir dir="${build.home}/WEB-INF"/>
<mkdir dir="${build.home}/WEB-INF/classes"/>
<!-- Copy static content of this
web application -->
<copy todir="${build.home}">
<fileset dir="${web.home}"/>
</copy>
<!-- Copy external dependencies as required -->
<!-- *** CUSTOMIZE HERE AS REQUIRED BY YOUR APPLICATION *** -->
<mkdir dir="${build.home}/WEB-INF/lib"/>
<!--
<copy todir="${build.home}/WEB-INF/lib" file="${foo.jar}"/>
-->
<!-- Copy static files from external dependencies as needed -->
<!-- *** CUSTOMIZE HERE AS REQUIRED BY YOUR APPLICATION *** -->
</target>
<!-- ==================== Reload Target =================================== -->
<!--
The "reload" signals the specified application Tomcat 6
to shut itself down
and reload. This can be useful when the
web application context is not
reloadable and you have updated classes or property files
in the
/WEB-INF/classes directory or when you have added or updated jar files
in the
/WEB-INF/lib directory.
NOTE: The /WEB-INF/web.xml
web application configuration file is not reread
on a reload. If you have made changes
to your
web.xml file you must stop
then start the
web application.
-->
<target name="reload" depends="compile"
description="Reload application on servlet container">
<reload url="${manager.url}"
username="${manager.username}"
password="${manager.password}"
path="${app.path}"/>
</target>
<!-- ==================== Remove Target =================================== -->
<!--
The "remove" target tells the specified Tomcat 6 installation
to dynamically
remove this
web application from service.
NOTE: This is the logical opposite of the "install" target.
-->
<target name="remove"
description="Remove application on servlet container">
<undeploy url="${manager.url}"
username="${manager.username}"
password="${manager.password}"
path="${app.path}"/>
</target>
</project>
