Why when I rename a project in Eclipse does Tomcat not pick up the new resource name?

Question

I did refactor > rename on a project in my workspace, but then when I went under the servers tab and did a right-click > Add and Remove for my Tomcat server in order to modify the resources configured on the server, the resource name for my project is my old project name. I looked everywhere to try and change this, like some sort of Tomcat config file or setting, but I can't find it anywhere. So my project is named one thing, but is configured as a resource on the server under a different name. How do I change this?

Answer 1

Edit your project name here:

Eclipse -> Project -> Properties -> Web Project Settings -> Context Root

This is where you want to edit the project name (too), and I believe it will also change the project/.settings/org.eclipse.wst.common.component file as mentioned in Yoni's answer above. I would recommend opening it to verify it though. If so, this is the better answer I believe.

EDIT: Anyone who verifies this, please post, and I'll append your verification to my answer.

2023-MAR UPDATE:

See both Tom Rutchik's reply and smat88dd's answer. Tom details this method does not change the "wb-module deploy-name" nor the property "java-output-path" in the org.eclipse.wst.common.component file. And smat88dd's answer of editting the org.eclipse.wst.common.component file manually may be the answer.

Added images and some information to @Yoni post.

Eclipse tomcat Add Remove still shows old project name. ^{Bug 180741}

File: D:\Yashwanth\MyProject.settings\org.eclipse.wst.common.component
Tomcat: MyProject(MyOldProject)

<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId" project-version="1.5.0">
    <wb-module deploy-name="MyOldProject">
        <property name="context-root" value="MyProject"/>
        <!-- ... -->
    </wb-module>
</project-modules>

How it looks like when you add a resource from eclipse.

To resolve the issue change from deploy-name="MyOldProject" to deploy-name="MyProject". After changing you will see in Tomcat as MyProject

Answer 3

Same issue and resolved it by changing manually deploy-name in project/.settings/org.eclipse.wst.common.component file and editing Context root in Eclipse -> Project -> Properties -> Web Project Settings -> Context Root. I have not encountered the issue since I did the trick.

Answer 4

The other answers didn't fix my issue. Deleting and then recreating my tomcat server worked. If you're still having issues run this command from a unix based terminal.

grep -Ril 'yourOldProjectName' 'C:\EclipseWorkspace\yourProjectsDir'

This will look through your entire project for your old project name. The output is the file names of all the files that have your old project name.

Answer 5

Answering Xonatron's message: changing the context root only changes the URL requested to reach the app. To change the 'resource name' as displayed in Eclipse you have to manually update the file project/.settings/org.eclipse.wst.common.component AND refresh the Eclipse project (F5).

Answer 6

Unfortunately, changing the Context Root does not update the org.eclipse.wst.common.component-file. So it is really necessary to change the deploy name in the file.

Answer 7

I believe you are looking for a hidden pref located under your project/.settings/org.eclipse.wst.common.component.

The beginning of the file should look roughly like this:

<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId" project-version="1.5.0">
    <wb-module deploy-name="projectB">

So just change the deploy-name. Another thing that I recommend changing is the project's context root, right-click the project -> Properties -> Web Project Settings.

(just to clarify, to the best of my understanding this behavior is a bug in WTP. WTP is responsible for maintaining the hidden pref file under .settings, and it just doesn't update the file when the project is renamed)
