Note on spring.io Spring tutorial

spring.md

This is my note when walking thru this tutorial "Developing a Spring Framework MVC application step-by-step". This records my updates to make things work.

Chapter 1. Basic Application and Environment Setup

1.3. Deploy the application to Tomcat

---

$ ant

BUILD FAILED c:\dev\springapp\build.xml:85: taskdef class org.apache.catalina.ant.InstallTask cannot be found using the classloader AntClassLoader[C:\dev\apache-tomcat-7.0.5\lib\catalina-ant.jar]

• Since tomcat 7, there has been a change and requires more jars. Add more jars according to this StackOverflow
• InstallTask fail. This is due to class InstallTask is deprecated by DeployTask according to this forum. (See also Tomcat API Doc) Just change the class name will do.

Solution: make changes to springapp/build.xml

$ diff todel build.xml 
81a82,86
>             <include name="tomcat-coyote.jar"/>
>             <include name="tomcat-util.jar"/>
>         </fileset>
>         <fileset dir="${appserver.home}/bin">
>             <include name="tomcat-juli.jar"/>

<     <taskdef name="install" classname="org.apache.catalina.ant.InstallTask">

>     <taskdef name="install" classname="org.apache.catalina.ant.DeployTask">

1.4 Check the application works

$ ant -v list

• Solution: in file 'springapp/build.properties', do this.

$ diff todel build.properties
 < tomcat.manager.url=http://localhost:8080/manager
 ---
 > tomcat.manager.url=http://localhost:8080/manager/text

Also, you would need to add "manager-scrpit" role in "$CATALINA_HOME/conf/tomcat-users.xml" as well. (See tomcat documentaion)
