I want to create easily a Tomcat Project in eclipse. This means that I want file tab then new tab then Tomcat Project tab. How can I do that?
You need to install the web tools into Eclipse, and then you'll be able to create a new web application project and then target it to a Tomcat server.

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 have checked out a dynamic web project from a CVS repository. But, there was no EAR file to check in. Now how can I create an EAR file for the project to deploy in WAS 6?
Also can I run my project in RAD without creating an .ear file? I am a newbie to Java EE projects.
In order to be able to export an EAR, you can add a new Enterprise Application project ( New > Enterprise Application project) and select your Web project as a Java EE module dependency.
This way you can export an EAR file that will contain a WAR file built from your Web project.
If you run the wizard for creating a new enterprise application (File->New), one of the options is to add an existing web project in your workspace into the application as you create it. You can then export the enterprise application as an EAR file ready to deploy into WebSphere Application Server or, if you have the test environment set up, you can just drag-and-drop it onto the server in the Servers view. To test your web application, right-click it and choose Run->Run on Server.
Try importing as project instead of EAR files
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.
I have developped a web dynamic application using JSP and servlet and I want to deploy it.
How to do it with eclipse.
how to do to launch the application.
Thanks for help.
Try Tomcat to deploy your application. You can easily integrate Tomcat into the Eclipse.
http://www.eclipsetotale.com/tomcatPlugin.html
Alternatively, instead of plugin, you can add the server into the Eclipse.
Ctrl -N > Server > Select Tomcat Server adapter
If you've developed your application as 'Dynamic Web Project' in Eclipse, the above process will detect your application, and asks you to select if it has to be deployed in the new server configuration.
To generate war file, right click on your project in 'project explorer' window, and click 'export as'. In the dialog box, select WEB > WAR file
Im new to Eclipse. I use Tomcat as my run time server, but every time I modified the jsp pages, Eclipse was still displaying the older one. Just wondering how to redeploy the application so the changes can be reflected.
Eclipse: Eclipse IDE for Java EE Developers 1.2.1.20090918-0703
Tomcat: Tomcat 6.0
Thanks
Doubleclick the server instance in question in the Servers view to open its configuration. Now, in the right top you should see a section called Publishing. Open it to verify and configure autopublishing settings.
Eclipse should do that automatically for you.
Otherwise, on the Servers view (Menu Window->Show View->Servers), you can right click on your Tomcat instance and hit "Publish" or "Restart"
Make sure you have the "JST Server Adapters" ("Web, XML and Java EE Development category") feature installed.
Eclipse's publishing functionality requries the project to be a "web project", and in some cases requires additional configurations.
Go to Windows > Preferences > Server > Runtime environments and add your tomcat
Either try using publishing, or (better I think) use the FileSync plugin. There you can tell which folders from your project should be copied (live) to what directory on your machine (the tomcat/webapps/yourapp). With a little more effort the filesync configuration can be made machine independent (only using one parameter as TOMCAT_ROOT), in case you want to check-in the project to a repository where others will use it.
Get the Tomcat plugin. It was nice because you can install Tomcat on your system and then associate your web app with that instance of Tomcat. The plugin will let you stop/start Tomcat and define a server such that when you do a build it knows how to deploy the changes. There may be some newer plugin but the Tomcat plugin worked for me and was fairly simple to install and use. Here is a page from IBM on using Eclipse and Tomcat. Inside that page it points you to the following: http://www.ibm.com/developerworks/opensource/library/os-eclipse-tomcat/
