Tomcat issues inside eclipse

I am very new to Tomcat and web development in general and apologize for what may be a very silly question.

Consider 2 situations:

1.

I start Tomcat outside of Eclipse.

I use eclipse to create a war file.

I deploy it via admin console.

All is ok

2.

I start Tomcat via Eclipse

I can't access admin conso开发者_JAVA技巧le

http://localhost:8080/manager/html greets me with 404 error

Same page is behaving properly when Tomcat is started outside of Eclipse

Please advise

You need to configure Eclipse to take control of your Tomcat installation. To do so:

• double click on the Tomcat Server in the Servers view
• under Server Locations, select Use Tomcat installation

This is illustrated on the screenshot below:

Eclipse creates a new Tomcat configuration separate to your Tomcat installation, in the 'Servers' project. This allows Eclipse to deploy webapps without interfering with anything you've done in your installation (via the manager app or by editing config files manually).

You can reconfigure Eclipse so that it uses the config from your Tomcat installation (see Pascal's answer), or to re-enable the manager app - but read the WTP Tomcat FAQ first as there are good reasons for it working the way it does. I don't recall ever needing to do this - the 'Servers' tab in Eclipse lets you deploy/start/stop/debug/configure apps as required.
