Let say that you have fresh download of Tomcat 6 and want to deploy your web application in it, but you don’t want to access your web application using URL form http://%5BIP_OR_DOMAIN_NAME%5D:%5BPORT%5D/%5BWEB_APPLICATION_NAME%5D (e.g http://localhost:8080/BlaBlaBla) instead you just want URL form http://%5BIP_OR_DOMAIN_NAME%5D:%5BPORT%5D (e.g http://localhost:8080) to access your application. There are few ways to do these that I know and I will it post here.
To deploy web application in Tomcat we can use WAR file or using webapp exploded directory, I will use the last one. You can deploy your webapp in “TOMCAT_HOME/webapps” directory or outside of Tomcat directory, I will use last one also. Now let see how to change Tomcat 6 ROOT context:
Open “TOMCAT_HOME\conf\server.xml” file, look for Host tag, add Context tag to it so it will looks something like these:
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> ............ ............ <Context path="" docBase="D:\Gardiary\temp\my-app" reloadable="true" debug="0" cookies="false"></Context> </Host>
Note that Context path is set to “” not “/” and docBase is path to your webapp exploded directory. Save it and run your Tomcat, you should be able to access your application just by using http://localhost:8080.
Remove (or change to other name) “TOMCAT_HOME\webapps\ROOT” folder, rename your webapp to ROOT and then put it in “TOMCAT_HOME\webapps” folder (a.k.a change the content of original ROOT folder with your web application content). Run your Tomcat.
Create file “TOMCAT_HOME\conf\Catalina\localhost\ROOT.xml“, the file looks something like these:
<?xml version="1.0" encoding="UTF-8"?> <Context docBase="D:\Gardiary\temp\my-app" crossContext="true" reloadable="true"> </Context>
Change docBase to your webapp exploded directory and then run your tomcat.
That’s all I know folks!
