GWT Tomcat Integration - Making Google Web toolkit work with Apache Tomcat

This is my quick and easy way to make GWT work with Tomcat.

Ingredients:

• GWT on Eclipse
• Apache Tomcat (I have 5.5.26)

Lets create a new GWT Project called "test".

Also download and copy the "tomcat-gwt.xml" to the "test" Project directory.
Edit the tomcat-gwt.xml files and add your project specific settings.

    <property name="tomcat.webapps" value="C:\apache-tomcat-5.5.26\webapps" />
    <property name="project.name" value="test" />   

Change the above settings to your specific settings.

Now add this builder to your project.
Right Click Project ("test") >>  Properties >> Builders

Select import to add the XML.

Make sure the tasks are selected as displayed below.

The application is deployed to tomcat everytime you do a "CLEAN".

Contents of "tomcat-gwt.xml"

<?xml version="1.0" encoding="UTF-8"?>
<project name="Tomcat-GWT" default="copy" basedir=".">
    <property name="tomcat.webapps" value="C:\apache-tomcat-5.5.26\webapps" />
    <property name="project.name" value="test" />       
    <property name="source.dir" value="${basedir}\war" />
    <target name="copyx">
        <echo>${source.dir}</echo>
        <echo>${tomcat.webapps}</echo>
    </target>
    <target name="copy">
        <mkdir dir="${tomcat.webapps}\${project.name}" />
        <copy todir="${tomcat.webapps}\${project.name}">
            <fileset dir="${source.dir}" includes="**/**" />
        </copy>
    </target>
</project>
