The packaging that you're using is an example that allows compiling the classes from Tomcat and your webapps into a native image. However, you are still running the usual Tomcat standalone, as well as your webapp. As a result, you still need a server.xml, all the other configuration files and resources that go in conf, and your usual unchanged webapp. There are solutions to "replace" the files in conf: - A custom ConfigurationSource implementation allows embedding files from conf into Java classes (which can then be compiled into your native image). - There's a tool which allows generating Tomcat embedded code from your server.xml. In addition to providing you with code examples if you want to learn the embedded API, this can also allow you to replace server.xml. However, if you prefer a fully packaged and AOT specific solution, you should look into the proprietary frameworks that target native images.

Re: Tomcat GraalVm native image issue
Thanks Remy for the response. I kept the main conf files under the module/stuffed/conf folder and then tried to build the native image following the steps given in the doc. When I run the native image from the stuffed folder it works and I am able to access the webapp. *But when I run the same native image from a different folder or on a different server, it asks for the server.xml file and fails to run.

You have to place a server.xml and all the other usual configuration files in the conf folder, this is really the same thing as the usual Tomcat standalone. It seemed explicit enough when I wrote the sentence in the doc. The idea is to not duplicate the default server.xml (and all the others everywhere for no reason. Would you have understood it better if "The main configuration files are placed in the conf folder" -> "The usual configuration files for Tomcat standalone (server.xml, web.xml, etc) should be placed in the conf folder" ?

Re: Tomcat GraalVm native image issue
I want to serve the static file of a reactjs application through this tomcat native image and I don't have any jar/war file to place under the webapps folder. But tomcat native image is not running without a server.xml file in the same path from where the native image is triggered.
