I have installed a clean version of netbeans 6.9.1 bundled with tomcat and glassfish. We have moved to netbeans from eclipse. All was working fine until about a week ago. We can start tomcat fine, from within netbeans. But when it comes to restarting or stopping the tomcat server from within netbeans, netbeans attempts to stop it for about 2 minutes and then reports: Stopping of tomcat failed. This means that everytime we want to stop tomcat we have to tell netbeans to stop tomcat and then end java.exe from task manager. No config files have changed, as far as I am aware.
