This basically means eclipse can’t connect to the target tomcat. This may be due to tons of reasons:

• tomcat isn’t started
• tomcat isn’t accessible over the network
• the debug port is not accessible (check firewall)
• tomcat isn’t configured to accept debugging (it should have something like the following in the startup script -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n)
