I’m kicking out a couple freelance projects using Struts<\/a> and Hibernate<\/a> in the next couple weeks, this weekend I was fiddling with the Ant<\/a> build script and I remembered Tomcat Manager App<\/a>, which allows you to reload contexts while Tomcat is running (as well as start, stop, install etc..). Unfortunately, the \/manager application only sees applications within the virtual host it’s running in and because I’m working with a couple different applications, I have multiple virtual hosts and I need to be able to utilize the \/manager application from each one. <\/p>\n

Turns out it’s not all that hard to get the \/manager application working within a different virtual host… as long as you read the documentation very thoroughly. It’s as simple as adding this:
\n
\n<Context<\/a> path=\"\/manager\" debug=\"5\" docBase=\"${CATALINA_BASE}\\server\\webapps\\manager\" privileged=\"true\"<\/b> \/>
\n<\/code>
\n(where ${CATALINA_BASE} is the absolute path to your tomcat install) to the virtual host element you have setup in server.xml (for those not experienced with Tomcat, adding a ‘context’ is similar to adding a virtual directory in IIS, make any more sense?). The one gotcha (in bold) is the privileged attribute. It *must* be set to true to run the \/manager or \/admin applications in virtual host besides localhost.<\/p>\n

Reloading the application using Ant is a breeze, the Tomcat documenation includes an example build file<\/a>, in short all you need is this:
\n
\n<property name=\"path\" value=\"\/myapp\"\/>
\n<property name=\"url\" value=\"http:\/\/localhost:8080\/manager\"\/>
\n<property name=\"username\" value=\"myusername\"\/>
\n<property name=\"password\" value=\"mypassword\"\/>
\n<taskdef name=\"reload\" classname=\"org.apache.catalina.ant.ReloadTask\"\/>
\n<target name=\"reload\" >
\n<reload
\n  url=\"${url}\"
\n  username=\"${username}\" password=\"${password}\"
\n  path=\"${path}\"\/>
\n<\/target>
\n<\/code>
\nMake sure that you have the catalina-ant.jar file coped from {Tomcat_install}\\server\\lib\\ to your {Ant_install}\\lib. If you are using Eclipse, go to Windows –> Preferences –> Ant –> –> Runtime –> Classpath and add catalina-ant.jar to the Runtime classpath.<\/p>\n","protected":false},"excerpt":{"rendered":"
