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?
This question is related to
eclipse
jakarta-ee
applicationcontext
contextroot
If using eclipse to deploy your application . We can use this maven plugin
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-eclipse-plugin</artifactId>
<version>2.10</version>
<configuration>
<wtpversion>2.0</wtpversion>
<wtpContextName>newContextroot</wtpContextName>
</configuration>
</plugin>
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.
In order to do that I need jboss-web.xml placed in WEB-INF
<?xml version="1.0" encoding="UTF-8"?>

"http://www.jboss.org/j2ee/dtd/jboss-web_4_2.dtd">
<jboss-web>
<context-root>somepath/Myapp</context-root>
</jboss-web>
In Glassfish you must also change the file WEB-INF/glassfish-web.xml
<glassfish-web-app>
<context-root>/myapp</context-root>
</glassfish-web-app>
So when you click in "Run as> Run on server" it will open correctly.
If the project is maven, change the "finalName" in pom.xml and Update Project as Maven.This worked for me.
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!
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:-
<Context docBase="abc" path="/abc" reloadable="true" source="org.eclipse.jst.jee.server:abc"/>
Here, you can just change your project context path to something else.
Hope this helps.
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
<build>
<finalName><any-name></finalName>
<plugins><provide-plugins-needed></plugins>
<build>
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).
In the java project, open .settings folder. there locate the file named "org.eclipse.wst.common.component" . Change tag <wb-module deploy-name="NEW_NAME"> .
Also you may want to change context root in project properties
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:
<Context docBase="Test" path="/test" reloadable="true" source="org.eclipse.jst.jee.server:Test1"/>
This path represents context path of your web application. By changing this path, your web app context path will change.
If using maven java ee 7/8 enterprise application, need to edit the pom.xml of the EAR project
<build>
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-ear-plugin</artifactId>
<version>2.8</version>
<configuration>
<version>6</version>
<defaultLibBundleDir>lib</defaultLibBundleDir>
<modules>
<webModule>
<groupId>com.sample</groupId>
<artifactId>ProjectName-web</artifactId>
<contextRoot>/myproject</contextRoot>
</webModule>
</modules>
</configuration>
</plugin>
...
</plugins>
</build>
