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


        

Answer 1

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

Answer 2

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>

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

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 "activate" 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.

1. In your project's Properties, choose Web Project Settings.

2. Change Context root to app.

   

3. Choose Window > Show View > Servers.

4. Stop the server by either clicking the red square box ("Stop the server" tooltip) or context-click on the server listing to choose "Stop".

5. On the server you want to use, context-click to choose "Clean…".

   

6. Click OK in this confirmation dialog box.

   

Now you can run your app with the new "app" URL such as:

http://localhost:8080/app/

Doing this outside of Eclipse, on your production server, is even easier --> Rename the war file. Export your Vaadin app as a WAR file (File > Export > Web > 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" this would be:

http://www.example.com/app/

Vaadin toolkit programmers may need to rebuild their widget set if using visual add ons.
