In <CATALINA_HOME>/webapps folder create the project structure for the getquote project as below
| Directory | Contains |
|---|---|
| /getquote | The root directory of the web application. All JSP and HTML files are stored here |
| /getquote/WEB-INF | This directory contains all resources related to the application that are not in the document root of the application. It is where the web application deployment descriptor web.xml is located. For the struts project, this folder will include the struts .tld. .dtd and .xml files. |
| /getquote/WEB-INF/classes | This is where the servlet and other classes are located. In struts 1.2 the struts.xml file is also placed in this directory. |
| /getquote/WEB-INF/lib | This directory contains Java Archive (JAR) files that the web application is dependent on. The jars from the blank struts project are copied here. |
| /getquote/src | The directory having the java source code. |
| /getquote/images | Image files are kept in this folder |
We create the ant build file using the script below
<project name="getquote" default="compile-single" basedir="."> <property name="src.dir" value="${basedir}/src"/> <property name="build.dir" value="${basedir}/WEB-INF/classes"/> <property name="lib.dir" value="${basedir}/WEB-INF/lib"/> <property name="tomcat.lib" value="E:/install/tomcat/tomcat11013/lib"/> <path id="classpath"> <fileset dir="${lib.dir}"> <include name="*.jar"/> </fileset> <fileset dir="${tomcat.lib}"> <include name="*.jar"/> </fileset> </path> <target name="clean"> <delete dir="${build.dir}"/> </target> <target name="init"> <mkdir dir="${build.dir}"/> </target> <target name="compile-single"> <echo message="Compiling LookupAction.java ..."/> <javac srcdir="${src.dir}" destdir="${build.dir}" classpathref="classpath" includeantruntime="false"> <include name="src/LookupAction.java"/> </javac> </target> </project>
God's Word for the day
A call to Repentance
Turn back to the Lord and forsake your sins;
pray in his presence and lessend your offense.
Return to the most high and turn away from iniquity
and hate intensely what he abhors
Sirach 17:25-26
The Golden Rule
In everything do to others as you would have them do to you;
For this is the law and the prophets
Mathew 7:12
