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>
