Did you Compile your Application? (GWT Compile Project)
You can then run this Ant buildfile and deploy the WAR file on your Tomcat Server.

Running GWT on tomcat in eclipse

I am trying to get a GWT Project running on a Tomcat 7 server in eclipse. I installed Tomcat and i can run other web application out of eclipse on Tomcat without a problem.
Now i generated a gwt maven project for eclipse with the following command and importet it as maven project to eclipse:
"mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo -DarchetypeArtifactId=gwt-maven-plugin"
I can run this now as Web application (with the google plugin) and i can build a "war" with maven and deploy this with the Tomcat management console on the server. Both is working. But if i choose the option in eclipse "Run on server" and choose tomcat than just the html is loaded but not the application itself. See the screenshot: It doesn't find the "GWTModule.nocache.js".
This file is available in the target folder. What do i have to change to tell tomcat to look in the correct directory?
Tomcat is not able to run GWT code in development mode. You can use Tomcat for server side code, but in this case you need to run GWT development mode with -noserver option (to prevent built-in Jetty instance from running). See this article for more details.
I would recommend using the wtp plugin for eclipse. If you do this you can add your project/resource to tomcat when adding a new server. Here are the steps to use if you already have your project imported into eclipse.
Window -> Show View -> Servers
In Servers
New -> Server -> Choose apache tomcat
Point to the location of your tomcat installation/download
Next
At this point you should be able to add your gwt-maven project which will add the target/project.war to the tomcat modules.
Save it
Click on the newly added server, then click the modules tab at the bottom kind of hard to see.
This should have your project shown in the list of web modules.
Start your tomcat instance then on your gwt application right click and choose Run As -> Web application. Make sure your configuration settings are correct and when the development server starts it should give you the development url to browse to.
You can configure some aspects of tomcat in the overview tab, I would recommend making sure that "Modules auto reload by default" is checked so that tomcat will watch the filesystem for class changes.

GWT App through tomcat on Intellij-Idea 10

Sounds simple, but I'm having lots of issues.
I want to run a GWT project in a tomcat on Intellij-idea 10.
Does anyone know how to set up the run config?
Regards,
Charles.
You can use '-noserver' option to start Dev Mode under Tomcat. Edit your GWT run configuration by adding '-noserver -port 8080' to 'Dev Mode parameters' field, then run the Tomcat configuration and after that run the GWT configuration.
This all implies that this is a development run, i.e. for local testing/debugging purposes. This is not deployment to production servers. I also assume you have GWT and Web facets defined for this project.
If you need GWT debugging, then you must run as GWT run configuration: here you can only choose a Default server (Jetty that comes with GWT) or an AppEngine Development server (if installed).
If you must run under Tomcat, then:
a. Add a Tomcat server under Settings - App Servers.
b. Create an Artifact - WAR exploded (under project settings). Add all items in right pane to the left pane.
b. Create a Tomcat run configuration with this Artifact.
You first run gwt compiler for compile gwt module, then compiler creates to your hosted .js and .html files. And you can run tomcat as usual but tomcat does not compiles your gwt modules.
I suggest you t use ant to compile gwt modules.

GWT issues when using RPC

I have spend more than one day trying to create a very simple hello world application in GWT but I am not being successful. I am trying to get a hello string from the server through RPC and display it on the client.
Thanks
Download a fresh copy of Eclipse Helios for java EE
Install the appropriate GWT Eclipse plugin
Start Eclipse, go to File->New Project, search for Google/Web Application Project
Project properties, Run As... Web Application
At this point you should have a fully functional GWT application.

How to set Tomcat or JBOSS or Glassfish as App-Server for GWT Web Project in eclipse

How to create and run GWT web project in eclipse with tomcat or another app-server?
I created a Gwt Project and when i run or debug it, eclise did use GWT hosted mode server.
I can not find and configuration in project properties to select tomcat or another server for the project/
Regards
In the GWT Run/Debug configuration of the project you want to run/debug, tab Main, deselect the "Run built-in server" option. After that, it's your responsibility to generate the html/js/images of the GWT module you want to run, and place them somewhere where Tomcat or JBoss can see them. That usually means deploying a war at least.

Eclipse Redeploy/Undeploy Web Project without Restarting the Server

In my eclipse web application I made a Web Project and a Library Project. The Web Project referenced the Library Project.
When I started the Server, every time I change a code in the Library Project and build it. The server wants to restart and it does not redeploy by the Web Project only. I do not want to restart the server because it takes a lot of time waiting the startup of the server.
Another is I am developing portlets using Liferay Portal and every time I change the Library Project, the auto-deploy of Liferay comes in but the Library Project Jar is locked and resulted to crash the portlet and did not deploy it until I restart the server.
Please Help!!!
In Java EE perspective find "Servers" tab at the bottom, delete your EAR out of there.
Try JavaRebel
If you install the nightly build of Liferay IDE (eclipse plugins for Liferay) it has support for delta-deployment where after the initial deployment (full deploy) it will only deploy the delta or just the individual files that you change as you save them (a single JSP or CSS file, etc).
