As I understood the situation, there is a conflict between the Tomcat server from outside the Eclipse with the Tomcat server from inside the Eclipse. I attached some picture that will explain the situation and I hope I can get your helpWhen I start the server from outside the Eclipse, but I have access the home page for the Tomcat server
When I want to start the Eclipse server while the Tomcat still working
[I stopped the Tomcat server from the Task manager, thus the Eclipse server start without conflict][3]
[With the Eclipse sserver, I lost the access to the Tomcat home page even it says the server tomcat working][4]
The problem is that the tomcat server must not start from inside the Eclipse, it should start from the cmd screen by using the files startup.dat and shutdown by using the shutdown.dat file using their path in the cmd like this:
D:\Apache-Software-Foundation\Tomcat-8.0\bin\startup.bat
D:\Apache-Software-Foundation\Tomcat-8.0\bin\shutdown.bat
As well as there is another problem, which is the server should change the folder name from (Apache Software Foundation) to (Apache-Software-Foundation). Otherwise, it will cause a problem when creating the Path for the server as well as it's better to install it on the Logical partition not in the System partition to avoid any configuration problem.

I have installed apache tomcat 7.0.47. I have used netbeans for a while, now i want to try eclipse. I've installed eclipse kepler. I have created my first struts application using it.
I have deployed few applications from netbeans which worked well. Now i cannot start up the tomcat server from eclipse. I'm getting message as
Several ports (8005, 8181, 8009) required by Tomcat v7.0 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).
I have checked that no javaws.exe running in process explorer. Also checked no processes using the port 8181 using netstat.
When i start the tomcat from bin using startup.bat it starts normally and i have checked in browser. It is showing the default page on localhost:8181 and listed in netstat.
Any way to start my first struts application in eclipse. Tried almost every thing but no improvement.
I have installed tomcat 7.0.37 and Eclipse juno on ubuntu 12.10 and build my first jsp based web app. but when I hit run as -> run on server eclipse shuts down. one issue is that on restart tomcat does not start and pops the error:
Several ports (8005, 8081, 8009) required by Tomcat v7.0 Server at localhost (2) are already > in use. The server may already be running in another process, or a system process may be >using the port. To start this server you will need to stop the other process or change the >port number(s).
In Tomcat installation folder, you can find a folder called conf and in that you can find a XML file server.xml.
This file contains the ports Tomcat has to use. Update that file with different port numbers and try again.
Okay, at last I solved it. first I changed the default browser from internal to system default and it solved the eclipse shut down. second I moved the files into the Web Content folder under project structure. and now I have a running JSP application. thanks to all geeks on web.
:)
If You use eclipse then double click on servers and double click on tomcat server then one file will open. in that change HTTP port to some other port number and save(ctrl+s) then again start the server . it may be work fine
I'm running Tomcat in Eclipse. I would like to see the Tomcat home page, however it doesn't show up. When I browse http://localhost:8080, then I get a HTTP 404 Page Not Found error.
How is this caused and how can I solve it?
Eclipse does by default not use Tomcat standalone. Instead, it overtakes its sole server engine and uses the workspace as deployment space instead of Tomcat's own /webapps folder. It also creates copies of configuration files like server.xml in the Servers project. It untouches the Tomcat installation. It untouches the Tomcat default homepage (and manager). It untouches existing deployments.
As the Tomcat homepage is not one of Eclipse projects (nor would become one), you won't see it when starting Tomcat from inside Eclipse like that. You would only see Eclipse projects which are deployed to the server by Add/Remove projects. I'm not sure why you need to see the Tomcat homepage as it has no utter value while developing Java EE web projects. But if you are really dead set on seeing it for some unclear reason, then you'd need to tell Eclipse to not only overtake its engine, but instead use the standalone installation at its entirety.
To configure that, double click Tomcat's entry in Servers view to open its configuration and in the Server Locations section, choose the option Use Tomcat installation.
You'll now be able to see Tomcat's homepage.
Again, the benefit is highly questionable. Do note that this way Eclipse will modify the Tomcat installation. So the Tomcat installation may not be reuseable across other IDEs/workspaces. You'd need to create a whole new Tomcat installation.
In eclipse,right click over tomcat server in servier view.
tomcate->properties.click switch location.
Try the following steps once:
1.Remove schoolManagementsystem folder and war file from webapps folder
2.Task Manager--> end the all java process
3.Now execute the command catalina.bat run in command prompt.
Hope this will help you .
I am using tomcat 6 and when I start it from the command line the application it's running works fine, but when I start tomcat from eclipse (I added it as a server in eclipse) I get a 404 error when I try to run the application in my browser. Any ideas why this is?
By default, when you reference an existing Tomcat instance in Eclipse, only its engine is been used. All already-deployed webapps in Tomcat's /webapps folder are ignored. You seem to expect that they are also accessible when you start Tomcat from inside Eclipse.
You need to configure the Tomcat server reference in Eclipse to set Server Locations to Use Tomcat installation instead of (default) Use workspace metadata. Double click the Tomcat server entry in Servers view to edit it.
This way, everything which is deployed to Tomcat, outside control of Eclipse, will also be available when you start Tomcat from inside Eclipse.
I installed tomcat on my ubuntu. When i create a new Dynamic Web Project I choose the tomcat 7 server. When I launch my page it works on localhost:8080/app/page but if I go on localhost:8080 it give me a 404 error.
If i start tomcat server with an external script like /etc/init.d/tomcat start, it works but I cannot launch my app because it says that the port 8080 is already occupied (by the other instance of tomcat).
I'm confused on how set everything, I would start tomcat at boot and link that instance for my apps.
Can you explain how I hato to do?
Open the server configuration in the Servers tab on Eclipse. On "Server Locations", mark "Use Tomcat installation".
EDIT: to be more precise, this will make Eclipse "take control" of your Tomcat folder. So it will not just make a replica on eclipse .metadata and deploy only your apps on it; instead it will be like if you ran bin/startup, but using some of the configuration defined on Servers view. So if you go localhost:8080 you will see the Welcome page, because /ROOT is now started by Eclipse.
So, I am not against "Starting/Stopping" the server from eclipse but to keep it simple, I think you can stop the server from eclipse (Click on windows/showview/Servers and then stop the server). Then I think you should not get an error if you start tomcat again from external script. Then you can right click on your dynamic web project in eclipse and export it as a war file inside tomcat-install--dir/webapps. Where your web application is available (on which context) depends on the web.xml file. If you need further info on this plz let me know.
