It looks like the classpath of the project is invalid, but you've not shown the Problems view that would show which error messages you have. Make sure that in Windows -> Preferences -> Java -> Installed JREs you have at least one valid JRE available and in the context menu of the project, you can look a the Properties -> Java Build Path to make sure there are no errors.

And if you're developing in Java, it makes sense to use a full JDK rather than a JRE.

After start tomcat in eclipse in authentication it give following errors please give suggestion

401 Unauthorized

You are not authorized to view this page. If you have not changed any configuration files, please examine the file conf/tomcat-users.xml in your installation. That file must contain the credentials to let you use this webapp.

For example, to add the manager-gui role to a user named tomcat with a password of s3cret, add the following to the config file listed above.
<role rolename="manager-gui"/>
<user username="tomcat" password="s3cret" roles="manager-gui"/>

Note that for Tomcat 7 onwards, the roles required to use the manager application were changed from the single manager role to the following four roles. You will need to assign the role(s) required for the functionality you wish to access.
manager-gui - allows access to the HTML GUI and the status pages
manager-script - allows access to the text interface and the status pages
manager-jmx - allows access to the JMX proxy and the status pages
manager-status - allows access to the status pages only

The HTML interface is protected against CSRF but the text and JMX interfaces are not. To maintain the CSRF protection:
Users with the manager-gui role should not be granted either the manager-script or manager-jmx roles.
If the text or jmx interfaces are accessed through a browser (e.g. for testing since these interfaces are intended for tools not humans) then the browser must be closed afterwards to terminate the session.

For more information - please see the Manager App HOW-TO.
