I am new to jsp. When executing java servlets normally we use Apache tomcat.Anyway I already have installed tomcat which comes with Xampp.I tried to configure existing tomcat server with eclipse,but failed getting an error from eclipse saying problems with port.But tomcat is the only process that is running on that port.
Does anyone know how to configure?
I have the same problem, it seems that you only must run one of servers, I mean from Apache Tomcat or Eclipse Tomcat, so if you want to use Eclipse Tomcat, you have to stop Apache Tomcat. I hope it helps although maybe you got the answer

I've got a poor beginner question about Spring/Eclipse usage.
I'm working on tutorials to learn Spring, coding "Hello World" or other little webapps running few controllers and JSP.
Each time I wanna run the app from within Eclipse, nothing happens. I just get a 404 error.
In order to make the web app works, I have to run my Tomcat outside Eclipse (ie launch Tomcat from Windows with the startup.bat command line) and deploy a War through the manager-gui window of Tomcat.
So it works, but it would be more comfortable directly from within Eclipse on the embedded servers because this way running tests are so loooooooooong...
In Eclipse, I tried :
Run on Server -> 404
Run a Maven conf with Clean-Install goals,
obtained a War, but was unable to use it from within Eclipse (it's
the same War I use in the Tomcat GUI) as I saw it here
So can someone tell me how to run a Spring webapp from with Eclipse to make my work easier ?
Thanx by advance.
You need to enable 'Use Tomcat Installation' option in tomcat server when controlling it inside eclipse.

Tomcat not starting from eclipse, this will solve your issue.
I'm currently using Eclipse Mars on OS X to build a PHP based application which requires a web server for a form submission. However, upon attempting to add Tomcat 7.0 as a server, the server list is empty (shown below).
I've been following several tutorials for setting up and configuring a Tomcat server and each one says to place the extracted Tomcat folder in the Eclipse workspace directory so they'll be detected when adding them in Eclipse. The Apache Tomcat folder is in the workspace directory but it still isn't being detected. I've tried reinstalling Eclipse and deleting any duplicate files but I keep getting the same result. How can I properly set up and configure an Apache Tomcat server in Eclipse Mars?
You can tell it about the Tomcat installation using the Server Runtime Environments preference page.
If Tomcat isn't already a known server type, you might need to install a few more. The WTP FAQ has instructions.
All of those tutorials are wrong. You do want to download a copy of Tomcat from Apache so it has the expected layout when Eclipse looks for the jars needed to launch it, but there's no reason to actually put it in the workspace.
I am also using Eclipse neon and I faced the same problem and the answer was available in a question Apache Tomcat Not Showing in Eclipse Server Runtime Environments in the same site already posted
Of the Available Answers the below steps Worked for me:
1.Help-->Eclipse Marketplace
2.Type Tomcat in search box and choose the Option JST Server Adapters(Apache Tomcat,...) and click on Install
3.Then complete the Simple installation steps and after installation Eclipse prompts for a restart accept and then you can see the Target Run time updated with Tomcat server
Note:I am using Windows
On my pc I have a running instance of tomcat, that I use with axis to export web-services. I'd like to use the same instance of tomcat with eclipse to run my servlets. How can I configure this?
create a basic web project in eclipse and try to deploy it, then it should ask for the server. if your eclipse is already configured with tomcat (even on axis), it should display for you to select as the application server.
try this tutorial which shows how to make it work.
it shows from the scratch (download tomcat and configure with Eclipse) but you can get an idea on the latter configuration.
When I'm trying to load the server from eclipse it not really deploying it, it start quite fast (without exception).
while i start the same app through tomcat the server is up and it working fine.
any idea what I'm doing wrong?
Thanks,
Gal
From what I understand ,the Apache Tomcat plugin supports up to version 3.6 (Helios) of Eclipse and not 3.7 (Indigo). Maybe I am wrong.
I'm developping a web application in Eclipse and I'm using maven, spring and tomcat.
Now the problem I have is that debug as => debug on server doesn't work.
I just get exceptions. (and yes I've created the server)
If I use the mvn command to compile it, put the war in my tomcat webapps dir and start my tomcat the application works fine. But for the functionallity I'm now working on debugging would be usefull.
I found the answer for this in http://jacksonps4.me/wordpress/?p=868
Worked like a charm for me, yet I don't understand anything!
We used to test our application with Tomcat as well, but switched to starting an embeddable Jetty. Here's a sample app. It's JSF, but it doesn't really matter. The pseudo-unit test simply starts a jetty "before" and shuts stops it "after". No need for external server infrastructure, no need for IDE dependencies.
you can run tomcat with maven with this command:
mvn tomcat:run
and if you want to debug, set this maven options:
export MAVEN_OPTS=-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
if you are in windows, use the set command:
set MAVEN_OPTS=-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
then you can debug with eclipse Remote Java Application.
Hope this help.
