Changing the context name in Tomcat

Sometimes, it may happen, you want to provide the application context name  different from the WAR file name while deploying in Tomcat.

Scenario:

WAR Name: ABC.war
The default url becomes: http://localhost:8080/ABC

Want to access the url as: http://localhost:8080/XYZ

There are 2 options available to do this change

Option #1:
Here is the steps that can be followed:

1. Navigate to <TOMCAT_HOME>/conf/server.xml
2. Goto the Host section & do the below changes
3. Change it to below:

 <Host name="localhost"  appBase="webapps"
      unpackWARs="false" autoDeploy="false" deployOnStartup="false">    

Please note, unpackWARs , deployOnStartup, autoDeploy all three should be marked as false, else 2 folders will be generated one with name ABC & another XYZ.

4. Add the context changes under Host

 <Host name="localhost"  appBase="webapps"
      unpackWARs="false" autoDeploy="false" deployOnStartup="false">  
<Context path="/XYZ" docBase="ABC.war"/>
 <!-- other preexisting configuration-->
<Host>
5. Start Tomcat going to <TOMCAT_HOME>/bin/startup.bat (windows) or <TOMCAT_HOME>/bin/startup.sh in Linux environment.

Option#2:

1. Explode the ABC.war (unzip the WAR file)
2. Place the exploded WAR in a folder outside Tomcat Directory (e.g. D:\mywebapps)
3. So, now the exploded WAR path will be D:\mywebapps\ABC
4. Create an xml file in <TOMCAT_HOME>/conf/Catalina/localhost named XYZ.xml (the name of expected context)
5. Now add the below line in XYZ.xml
6. <Context path="/XYZ" docBase="D:/mywebapps/ABC"/>
7. docBase refer to the path where exploded WAR is placed.
8. Start Tomcat going to <TOMCAT_HOME>/bin/startup.bat (windows) or <TOMCAT_HOME>/bin/startup.sh in Linux environment.
