• Getting the “Application Server Libraries not found” error with IntelliJ when you try to add a local Tomcat server? If you’re using Gentoo it’s a matter of file locations. Install the tomcat-api package, and make a symbolic link from the API within the Common and Shared Tomcat directories. Source.

  • Tomcat 7 has changed around how resources can be accessed. You can no longer use “getResourceAsStream” to get files placed in the Web-inf/Classes folder. Instead, you should attempt to get the resource through the context of the local thread. An example: Thread.currentThread().getContextClassLoader().getResourceAsStream(). This is useful for applications that use JasperReports [location of the JRXML file], and that are web applications. Source.

  •  If you are trying to stand up a web server, and don’t want to allow it to accept public connections? Set the accepted connections on tomcat to only listen on the local address. For tomcat see this. For NGinx see and set it only set listen to[port].

  • Converting a GUI Netbeans project into a Maven based project? Most of the needed libraries will be covered by the default Maven repositories. However the swing-layout dependency is a special case. To use include the Netbeans repository reference, and include the swing-layout-1.0,4 dependency. **Repository: **
