I have read through the examples, unit tests, and documentation regarding undertow. I have coded and run my "plugin" implementation, but all I am getting are "Not Found" responses in the browser. My suspicion is that the web.xml is not being read in and / or parsed, but I'm not sure since I'm new with this code base. Below you will see how I'm setting up and starting things; let me know what I'm doing incorrectly.</div>
</div></blockquote><div>Hi <span style="font-family:Helvetica,Arial,sans-serif">Mondain,</span></div><div><span style="font-family:Helvetica,Arial,sans-serif"><br></span></div><div><span style="font-family:Helvetica,Arial,sans-serif">You are correct in your suspicion that Undertow is not parsing the web.xml. Undertow provides an embedded Servlet implementation but it does not implement the discovery/parsing parts, as this is left up to the embedding application. </span></div>
<div><span style="font-family:Helvetica,Arial,sans-serif"><br></span></div><div><span style="font-family:Helvetica,Arial,sans-serif">Basically instead of using web.xml you need to add servlets, filters etc to the DeploymentInfo structure programatically. The main reason for this is basically because Undertow is designed to integrate well into other applications (especially Wildfly), and application servers generally provide their own implementation of parsers, annotation processors etc. </span></div>
<div><span style="font-family:Helvetica,Arial,sans-serif"><br></span></div><div><span style="font-family:Helvetica,Arial,sans-serif">With that said though at some point we will probably do a standalone parser/annotation processor to make this work out of the box (probably by just copying the relevant bits from wildfly and packaging them in their own jar). This is a fairly low priority item at the moment though.</span></div>
