Tomcat fails to start in Eclipse - java.net.BindException: Address already in use

Question

I'm new to Tomcat and Eclipse, but have been searching for a solution for days. I've installed Tomcat v7.0 and can start/stop it from the terminal, but I can't get it to work from Eclipse. I'm following the tutorial at http://www.vogella.de/articles/EclipseWTP/article.html#jspservlets, but when I attempt to run my servlet I get the alert: "Server Tomcat v7.0 Server at localhost failed to start" with the console output as:

netstat doesn't show ports 8080, 8005 or 8009 in use before I attempt to run Tomcat, so that doesn't seem to be the problem. Any idea what's going wrong?

Answer 1

step 1: go to C:\Windows\System32\drivers\etc

step 2:

find hosts file and open it with notepad with admin mode

step 3:

replace local host ip with 127.0.0.1

example

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
    127.0.0.1       localhost
#   ::1             localhost

step 4:

save that file and run server

Answer 2

Change Tomcat port setting:

It seems the Tomcat is already integrated in Eclipse. So there should be a project called "Servers" in your Eclipse, you could find your Tomcat configuration node. Change the port attribute in server.xml. Of course, the plugin provides many ways to integrate with Tomcat, but basic idea is to change server.xml.

Answer 3

It seems when you installed Tomcat- it decided to run in service mode and must be running when you start your system. Hence the error when you start the tomcat through eclipse.Using other ports in server.xml maynot solve your problem.My guess is that another instance of tomcat is already running.Can you check in taskmanager of another instance of tomcat is running before you start it from eclipse ? Also can you post result from netstat run ?
