I've got a project called CodeProjects that I've made in eclipse and want to upload it to my remote server, the problem is I need to configure it run in the ROOT folder so I can access the site via domain.com/ but tomcat unpacks the .war file and configures it to run as domain.com/CodeProjects/ how do I change this? Thanks.

I am using tomcat server , I build my dynamic web project and add to it external js files and other files ... it run fine ... But Now the tomcat run the specific code which I use js files and other files not correct .. I did not knew what the problem the tomcat was run fine why Now it did not run fine my dynmic web project ... any body can help ?
Export your eclipse project as war file and place in the tomcat/webapps folder.
Start your tomacat service here http://help.eclipse.org/kepler/index.jsp?topic=%2Forg.eclipse.wst.webtools.doc.user%2Ftopics%2Ftwcrewar.html
I'm trying to use Openshift to host my java webapps. The problem I am running into is every time I go to my application "http://omniticketmvc-leviliester.rhcloud.com/" it takes me to a "Welcome to your JBossEWS (Apache/Tomcat) application on OpenShift".
I thought maybe it was because my project had some sort of default .war that was being deployed instead of the one I wanted. To try to confirm that I followed this guide made by to deploy a pre-compiled War file. https://www.openshift.com/kb/kb-e1088-how-to-deploy-pre-compiled-java-applications-war-and-ear-files-onto-your-openshift-gear .
As you can imagine that did not work. The guide implies that I should be able to find my webapp running at app-domain.rhcloud.com/mywebsite with "mywebsite" being the name of the war file my project created. In this scenario my Application war file is name "OmniTicket". I can find that war file on the server using ssh but the directory hierarchy is confusing to me.
I also tried looking in logs on the server but I don't see any errors to indicate a malfunction in spring or database connections. Any help would be appreciated. Specifically when I deploy my application to the Jboss Server without any obvious errors, why can't I get to the application root?
I should also mention it is a SpringMVC restful service application that works locally.
Try following steps:
Rename your war name to ROOT.war
Delete the src and pom.xml. If pom.xml is present then OpenShift would try to build the maven project
Place the war in deployments folder under your application root folder
Commit the war and push changes to application Git repository.
Check the logs using rhc tail command
How do we a deploy a simple war file on the websphere server 8 without using the websphere administration console?
As a part of the manual deployment I will need to know,
where to put the war file manually on the server?
war uses jndi for db connection, since we do not want to use admin console,
how do we create jndi data sources?
we would also want to externalize the properties file. (like I used to keep
application.properties in JBOSS_HOME/server/default/conf folder in jboss instead of the app.war/web-inf/classes)
Please help
PS: Actually we will be having an ant build which will do these three things for us so that we don't have to go to the admin console. Just run the ant build and it will copy war, create jndi etc stuff.
The best way of doing what you want is writing a wsadmin script.
Using wsadmin you can deploy, add/delete/modify resources in WebSphere, pretty much anything.
I would suggest you read Getting started with wsadmin scripting
You can also use 'monitoredDeployableApps' folder under server profile. You can enable this feature from the admin console -> Applications -> Global deployment settings.
Simple and best way to do this is in two steps: (v 8+)
Enable 'monitoredDeployableApps' feature in Admin Console -> Applications -> Global Deployment Settings and restart the server. (once restart you will see a folder in your profile 'monitoredDeployableApps' (default name and can be changed while enabling this feature)
Drag and Drop your war file in this folder (no restart needed) and observer Systemout.log of the server. Verify in Admin Console for the deployed application.
NOTE: Make sure your context-root is populating to your deployable (war,ear,...) files.

I have developed an web application using HTML, Java Servlet and all. While developing I was using Tomcat to deploy it in order to test it.
Now my development is done and I want to make it live. For that we have live server but as I am new to all this I dont know how to deploy my java web application on live server?
So please help me if you know to answer?

I am also using MySql so what I have to about it..
You will have to build a WAR of the project.
You can do this
in eclipse: right click on the project, Click "Export", and choose war file in the dialog (and mention, the destination, name and all)
via ant using the war task
The ant option is better because when you have multiple developers on the project and the code is in version control, it is easier to get the project automatically (using ant) and build a war. (you have version control, don't you?)
But this is more of an operational difference (albeit an important one) but the war created in either way are same
Deploy the war to the server
You can manually copy the war file to the $TOMCAT_HOME/webapps directory (See the "Creating and Deploying a WAR File" section on this article)
You can use the Tomcat 6 "Manager" application.
Update
You said that you are using MySql also. MySql should be installed on a server (it can be on the same server) and the configuration should be changed (username, password, server details) so that the application connects to the same database (I am sure you are not hard coding database details and credentials in your application and reading them from some configuration, this is the configuration that has to be changed)
For that we have live server but as I am new to all this I dont know how to deploy my java web application on live server?
I assume by this you meant , you have a public IP assigned to a server. Now you can install tomcat into this server and open the tomcat port for public and you will be able to access.
Now build a war file of your webapplication and put it into web-apps dir of the tomcat and start the server
Making a few assumptions here. You need
A tomcat instance running on your production server
Permissions to make changes to the tomcat instance
A war file that bundles your application
If you have both, then you need to navigate to the Tomcat manager page and follow the instructions to upload your war file.
Deploy the war to the server
You can manually copy the war file to the $TOMCAT_HOME/webapps directory.
You can use the Tomcat 6 "Manager" application.
I use Tomcat 6.0 and Eclipse 3.0 under Linux and I try to deploy a WAR in Tomcat. The problem is that the server is managed by Eclipse and I have some Eclipse project deployed. I tried to modify the server.xml file then launch Tomcat via Eclipse but it doesn't work:
Could not load the Tomcat server configuration at /Servers/Tomcat v6.0 Server at localhost-config. The configuration may be corrupt or incomplete.
I tried to extract the war in the webapps directory but the webapp is still inaccessible.
What is the best practice to deploy a War ?
Tomcat behaves differently in development and production mode. When you develop your webapp in Eclipse there is no reason to deploy a WAR file of your application as a WAR during development.
Just go to the "servers" view and add a new server (you should already have done this otherwise you could not create your Dynamic Web project). In the server view you should see the server you created (Tomcat at localhost or something similar) just right click it and go to the Add and Remove section. Here you can add and remove the Dynamic Web projects you created in Eclipse. Once you added your project, all you have to do is click the green start button in the servers view and your app should be available in at localhost:8080/mycontext.
When you're done building your app just right click the project and go the the Export section in the menu. You should be able to export a WAR file. Once you have your WAR file you can upload and deploy that on a Tomcat instance that is NOT tied to Eclipse running in dev mode.
Yes, in a way, you can deploy a war in the dev mode.
I have the same problem.
I have an Eclipse webapp project, which Eclipse deploys to an instance of Tomcat run by Eclipse, so I can hot-edit the project.
This Web project needs to use resources published by another webapp that has to be run within the same instance of Tomcat. The other webapp is a completed project by someone else, so it is already in a war form.
I needed to File->Import the war as an Eclipse project and let Eclipse deploy it to the same instance of Eclipse, in order to run it in the same instance of Tomcat in which my webapp also runs.
The problem is that some wars work this way but some others do not, while all of them work perfectly fine in a stand-alone Tomcat (started by startup.sh). I can't figure out why.
This is old but is one of the first answers in google search.
You can import the war file:
A Web Archive (WAR) file is a portable, packaged Web application
that you can import into your workspace.
Before importing a WAR file,
you should first determine if the WAR file contains needed Java™ source
files. When importing a WAR file into an existing Web project, the imported
Web deployment descriptor files are either not changed or overwritten by the
ones included in the imported WAR file, based on your response to the prompt
that is provided. In either case, this action does not represent a
merging of the two sets of deployment descriptors.
To import the
Web project resources in a WAR file into your workspace, complete the following
steps:
Select File > Import
.
In the Import dialog, select WAR file and
then click Next.
Locate the WAR file that you want to import using the Browse button.
The wizard assumes you want to create a new Web project with the
same name as the WAR file. If you accept this choice, the project will be
created with the same servlet version as specified by the WAR file and in
the same location. If you want to override these settings, you can click New and
specify your new settings in the Dynamic Web Project wizard.
Click Finish to populate the Web
project.

If all you have is a binary WAR (no source code), it cannot be installed within Eclipse. This can happen in certain scenarios outside of normal development workflows. Here's the work-around solution:
Launch another instance of Tomcat (outside Eclipse).
Modify the tomcat-users.xml file to enable admin
Go to http://localhost:8080/manager/html
Scroll down to WAR file to deploy
Click Choose File (next to Select WAR file to upload) and click Deploy.
