[eclipse] "starting Tomcat server 7 at localhost has encountered a prob"

Trying configure tomcat in my eclipse but "Port 8080 required by Tomcat v7.0 Server at localhost is 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 tried to set up tomcat environment several times but it hitting me with this error any thing i need to do in my eclipse?

Method 1:

• type localhost:8080 in your browser to know which process is taking 8080 port
• uninstall that program

Method 2:

re-install the apache tomcat BUT during installation change the port number. Watch carefully the installation process

nop... just open the four dateis: content.xml; server.xml; tomcat-users.xml and web.xml in the tap servers. There are some text. Change the number of port 8080 to 8081

1. Close Eclipse
2. Copy all files from TOMCAT/conf to WORKSPACE/Servers/Tomcat v7.0 Server at localhost-config
3. Start Eclipse
4. Expand the Servers project, click on the Tomcat 7 project and hit F5
5. Start Tomcat from Eclipse

Hey i got the solution recently... Just copy the "ROOT" folder FROM C:\Program Files\ Apache Software Foundation\ Tomcat 7.0\ webapps \ TO your_Workspace\ .metadata\ .plugins\ org.eclipse.wst.server.core\ tmp0 \wtpwebapps\ and over write it when asked..

This is needed because eclipse forgets to copy that root folder to its workspace.. Just right click on Apache tomcat 7.0 in servers tab and observe that in location will be workspace metadata by default example:"location:[workspace metadata]". Therefore it will find the root folder which has the welcome page in it and the 404 page not found error will be displayed. Thankyou ..

In eclipse->in server tap-> double click on Tomcat server at localhost-> Ports -> HTTP/1.1

Default port number will be 8080. Change this to 8081. Tomcat version7.0

I have configured tomcat server also in NetBeans IDE 7.4 for JSP. So am facing this issue.

In Servers view double-click on Tomcat and change HTTP port in Ports section to something else. Or in Package Explorer navigate to Servers Tomcat and change Connector port part inside server.xml file.

I was having the same problem when my workspace was in E:\ drive. Then I changed my workspace location to C:\User\\ location. The problem seems to be solved now.

Go to web.xml add <element> before <web-app> and close </element> after </web-app>

should be somethings like this

<?xml version="1.0" encoding="UTF-8"?>

<element>

<web-app>

....
</web-app>

</element>

to overcome this kind of problem follow the steps below:

• open command prompt.
• c:\Users\CGITS_04> netstat -o -n -a | findstr 0.0:80
• then you can see a list of process that is currently using port 80.
• open task manager->search the process-> select and end process.
• Now open eclipse and start tomcat.
• happy coding!

Open the terminal in ubuntu (ctrl+shift+t)
sudo gedit /etc/tomcat7/server.xml

change the default port in the server.xml,from 8080 to anything like 8081,8181,8008. Then save the file .

Now the project will work nicely without any interruption.
