The following error occurs when Tomcat startup in eclipse times out:

Server Tomcat v6.0 server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.

Start the eclipse startup project today and prepare for development. The above error is displayed, which limits the deployment time and causes the error. Modified servers. xml in the eclipseworkspace \. Metadata \. plugins \ org. Eclipse. WST. server. Core directory.
The start time is 1000 start-Timeout = "1000". Remember to restart eclipse. It took me 10 minutes to restart.
