How to change context root of a dynamic web project in Eclipse

Question

I developed a dynamic web project in Eclipse   I can access the app through my browser using the following URL    http   localhost 8080 MyDynamicWebApp   I want to change the access URL to   http   localhost 8080 app   To do so  I changed the context root from the project  Properties   Web Project Settings   Context Root   However  the web app still has the same access URL  I have re-deployed the application on Tomcat and re-started the Tomcat  but the access URL is the same as earlier   I found that there was no server xml file attached with the WAR file  Without the server xml file attached  how is the Tomcat determining that the context root of my web app is  MyDynamicWebApp and allowing me to access the application through this context root URL

I know the answer has been accepted already  But  just in case anyone using Maven wants to achieve the same thing  just set the finalName in the maven build to whatever name you want to give and do a maven -  update project   lt build gt       lt finalName gt  lt any-name gt  lt  finalName gt       lt plugins gt  lt provide-plugins-needed gt  lt  plugins gt   lt build gt

After changing the context root in project properties you have to remove your web application from Tomcat  using Add and Remove    on the context menu of the server   redeploy  then re-add your application and redeploy  It worked for me   If you are struck you have another choice  select the Tomcat server in the Servers view  Double clicking on that server  or selecting Open in the context menu  brings a multipage editor where there is a Modules page  Here you can change the root context of your module  called Path on this page

I just wanted to add that if you don t want your application name in the root context at all  you and just put      no quotes  just the forward slash  in the Eclipse --  Web Project Settings --  Context Root entry  That will deploy the webapp to just http   localhost 8080   Of course  this will cause problems with other webapps you try to run on the server  so heads up with that   Took me forever to piece that together    so even though this post is 8 years old  hopefully this will still help someone

Setting the path to nothing in the Eclipse web modules edit dialog enabled me to access the project without any path component in the URL  i e  ROOT   You can reach the web modules edit dialog by pressing F3 if you select Tomcat in the  Servers  view or by double clicking on it   Some screenshots

If using eclipse to deploy your application   We can use this maven plugin    lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-eclipse-plugin lt  artifactId gt       lt version gt 2 10 lt  version gt       lt configuration gt           lt wtpversion gt 2 0 lt  wtpversion gt           lt wtpContextName gt newContextroot lt  wtpContextName gt       lt  configuration gt   lt  plugin gt    now go to your project root folder and open cmd prompt at that location  type this command    mvn eclipse eclipse -Dwtpversion 2 0  You may need to  restart eclipse   or in server view delete server and create agian to see affect  I wonder this exercise make sense in real life but works

I tried out solution suggested by Russ Bateman Here in the post  http   localhost 8080 Myapp to http   localhost 8080 somepath Myapp  But Didnt worked for me as I needed to have a   war file that can hold the config and not the individual instance of server on my localmachine   Reference  In order to do that I need jboss-web xml placed in WEB-INF   lt  xml version  1 0  encoding  UTF-8   gt    lt  -- Copyright  c  2008 Object Computing  Inc  All rights reserved  -- gt   lt  DOCTYPE jboss-web PUBLIC  -  JBoss  DTD Web Application 4 2  EN   http   www jboss org j2ee dtd jboss-web 4 2 dtd  gt      lt jboss-web gt     lt context-root gt somepath Myapp lt  context-root gt     lt  jboss-web gt

Apache tomcat keeps the project context path in server xml path  For each web project on Eclipse  there is tag from there you can change it  Suppose  there are two or three project deployed on server  For each one context path is stored in   This tag is located on server xml file within Server created on eclipse   I have one project for there on context root path in server is    lt Context docBase  Test  path   test  reloadable  true  source  org eclipse jst jee server Test1   gt    This path represents context path of your web application  By changing this path  your web app context path will change

In Glassfish you must also change the file WEB-INF glassfish-web xml   lt glassfish-web-app gt       lt context-root gt  myapp lt  context-root gt   lt  glassfish-web-app gt    So when you click in  Run as  Run on server  it will open correctly

If you are running Tomcat from Eclipse  it doesn t use the configuration from your actual Tomcat installation  It uses the Tomcat configuration that it created and stored under  Servers  project  If you view your Eclipse workspace  you should see a project called  Servers   Expand that  Servers  project and you will come across server xml  Open this file and scroll all the way to the bottom  and you should see something like this -   lt Context docBase  abc  path   abc  reloadable  true  source  org eclipse jst jee server abc   gt    Here  you can just change your project context path to something else   Hope this helps

I m sure you ve moved on by now  but I thought I d answer anyway  Some of these answers give workarounds  What actually must happen is that you clean and re-publish your project to  quot activate quot  the new URI  This is done by right-clicking your server  in the Servers view  and choosing Clean  Then you start  or restart it   Most of the other answers here suggest you do things that in effect accomplish this  The file that s changing is workspace  metadata  plugins org eclipse wst server core publish publish dat unless  that is  you ve got more than one server in your workspace in which case it will be publishN dat on that same path  Hope this helps somebody   Not sure if this is proper etiquette or not     I am editing this answer to give exact steps for Eclipse Indigo   In your project s Properties  choose Web Project Settings   Change Context root to app    Choose Window  gt  Show View  gt  Servers   Stop the server by either clicking the red square box   quot Stop the server quot  tooltip  or context-click on the server listing to choose  quot Stop quot    On the server you want to use  context-click to choose  quot Clean    quot     Click OK in this confirmation dialog box     Now you can run your app with the new  quot app quot  URL such as   http   localhost 8080 app   Doing this outside of Eclipse  on your production server  is even easier -- gt  Rename the war file  Export your Vaadin app as a WAR file  File  gt  Export  gt  Web  gt  WAR file   Move the WAR file to your web server s servlet container such as Tomcat  Rename your WAR file  in this case to app war  When you start the servlet container  most such as Tomcat will auto-deploy the app  which includes expanding the war file to a folder  In this case  we should see a folder named app  You should be good to go  Test your URL  For a domain such as  example com quot  this would be   http   www example com app   Vaadin toolkit programmers may need to rebuild their widget set if using visual add ons
