I have a GWT project and I can run it via hosted mode of build.xml.
But in case I don't have it(projects that I created by eclipse plugin) I run it by running com.google.gwt.dev.DevMode.class file but it says :
Plugin failed to connect to Development Mode server at 127.0.0.1:9997
why? :(
Well if you have the Eclipse plugin, you can use it to run your project as a GWT app. Right click on your project or module.gwt.xml file > Run as > GWT Application. If you have multiple modules, it will let you pick a module, and it might ask you to pick the hosted html file.
Doing that will use the Devmode class to run your app.

I have a Advanced Java Application(Spring+Hibernate) with Maven. Project runs without any error.
I follow below process to test the application.
Build War using below command.
C:\Dev\ProjectApp> mvn clean package -Dmaven.test.skip=true
This builds war file inside target folder(C:\Dev\ProjectApp\target).
Place Application.war inside webapps folder(C:\Apps\Apache\Jakarta\Tomcat6\webapps)
run startup.bat from Tomcat6\bin folder.
hit the application in web Browser (http://localhost:8080/).
I want to debug this application from eclipse IDE itself. While application runs in webbrowser. I want to debug using breakpoints.
What are the steps to run this application in eclipse? What are constraints involved in this?
Thanks in Advance !
To simply debug the flow of the application, you can use the eclipse as the basis.
Goto the server view and create a new tomcat server (or any server that you use for dev). Next right-click on your project --> run as --> run on server and select the server that you just created. Keep in mind that the server should have all the configurations that you need to have to run the application. If your project requires some custom settings in the application server, then tell eclipse to take control of the server installation by selecting "Use Tomcat installation". (double click on the server to configure it)
Next add debuggers and start the server from within eclipse.
Happy debugging !
Set the environment variables first
set JPDA_ADDRESS=8000
set JPDA_TRANSPORT=dt_socket
You can edit the startup.bat to have
call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS%
and start in the same way as above.
After this you can have your eclipse open a remote debugging session that connects to localhost:8000.
However, I would strongly recommend to use the WTP plugin in eclipse to build and start/stop the tomcat from within eclipse itself.
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.
I want to use maven to run my application in test mode. I have a multi module project which uses gwt. To debug my app I want to do the following:
Run jetty in exploded directory
Run gwt in a hosted mode with -noserver option
Now I have to do this manually in the IDE. Is there any way to do this automatically from maven?
Using Maven, you can use the jetty-maven-plugin to run Jetty in your server module (use the start or run goal), and the gwt-maven-plugin to launch GWT's DevMode (use the run or debug goal).
To my knowledge, you cannot however do that with a single Maven command.
Have a look at https://github.com/tbroyer/gwt-maven-archetypes for sample configurations of such multi-module GWT projects.
I am creating a gwt application as following steps:
First install gwt plugin in my eclipse(Helios).
Create GWT project
Add Dynamic web plugin
going to property page of the project
project Facets tab
Select Dynamic Web Module and java
ok to apply changes.
Write code
and i try to run on server tomcat7 then it shows resources not available.But when i run as internal server of gwt as just right clicking on project and selecting run as web application.
then it run successfully. so please help to run my application on tomcat server.
Thanks

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