Fixing Error : SpringMVC apache tomcat catalina installtask not found

While working with SpringMVC, I recently found some issues which are raised when we try to build the application using apache ant. I am using apache tomcat as my servlet container. Here is the build.xml file that i am using.


<?xml version="1.0"?>

 </fileset>

 </path>

<target name="install" description="Install application in Tomcat">

<target name="list" description="List Tomcat applications">
 <list url="${tomcat.manager.url}"

 </target>

<!-- End Tomcat tasks -->

</project>

And here is the build.properties file.

# Ant properties for building the springapp

appserver.home=C:/apache-tomcat-7.0.27
# for Tomcat 5 use $appserver.home}/server/lib
# for Tomcat 6 use $appserver.home}/lib
appserver.lib=${appserver.home}/lib

deploy.path=${appserver.home}/webapps

tomcat.manager.url=http://localhost:8080/manager
tomcat.manager.username=tomcat
tomcat.manager.password=s3cret

But this gave me the above error mentioned in the topic of this post. And here is the way to solve it. Change this t


<taskdef name="install" classname="org.apache.catalina.ant.InstallTask">
 <classpath refid="catalina-ant-classpath"/>
 </taskdef>

into this.


<taskdef name="install" classname="org.apache.catalina.ant.DeployTask">
<classpath refid="catalina-ant-classpath"/>
</taskdef>

The reason is that the installTask class has been outdated. This might be OK with older Tomcat versions. But not with the new versions. 🙂 🙂
