<!-- ==================== Install Target =================s================= -->

	    path="${path}"
         [b]   war="file:/${dist.home}/${path}.war"/>[/b]

  </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 5 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="${url}"
        username="${username}"
        password="${password}"/>

  </target>


<!-- ==================== Prepare Target ================================== -->



  <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 5 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="${url}"
       username="${username}"
       password="${password}"
           path="${path}"/>

  </target>


<!-- ==================== Remove Target =================================== -->

<!--

  The "remove" target tells the specified Tomcat 5 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="${url}"
         username="admin"
         password="admin"
             path="${path}"/>

  </target>

i did necessary changes to managet.xml file

What is that ? where it is used? And are you able to access the manager console through the browser ?

[Vas Miriyala]

when i started tomcat using command line ,then i can able to logon to managet,when i start tomcat in eclipse,i can not able to see the manager and not even tomcat welcome page,can you tell me what is the problem

[Vas Miriyala]

problem solved and I changed the path like this war="file:${dist.home}/${path}.war" works without making any errors and now i can able to logon to tomcat-manager with in eclipse

[Peter Johnson]

srinivas, build scripts are much easier to read if you use the code tags, which I added to your post.
And thank you for posting the solution for your problem, that will benefit future ranchers with similar issues.

[Vas Miriyala]

thanks for your reply and Now everything is working fine
