Hi, Openshift Origin uses Hawkular Metrics to store node and container data. In this scenario, Hawkular Metrics calls the Kubernetes master server over HTTPS to validate the client identity. This is implemented with Undertow Client, as part of a ServletExtension (inside Wildfly 10) [1]. Works fine in development and testing. Now the Openshit team sees errors in the logs [2][3]. I couldn't reproduce yet. Errors come in pair, first the "UT005001: An exception occurred processing the request: java.lang.IllegalStateException: XNIO000017: Buffer was already freed", and just after "XNIO001007: A channel event listener threw an exception: java.lang.NullPointerException". Does that ring a bell? I haven't been able to find a starting point by looking into the source the code. Thanks -- Thomas Segismont JBoss ON Engineering Team [1] https://git.io/vrNyP [2] https://issues.jboss.org/browse/HWKMETRICS-408 [3] https://issues.jboss.org/secure/attachment/12405779/hawkular.log

Correctly shutting down a websocket handler

by Robin Anil

When a client disconnects, I see that onClose is not being fired. The only way this seems to be firing if client sents a close frame. Is there any way to detect disconnection and immediately close all the opened resources. Robin Robin Anil | Software Engineer

Re: [undertow-dev] Configure Undertow to use ViewResolver similar to Spring MVC and serve static content

by Stuart Douglas

It sounds like you need to configure a resource manager to serve static content. You need to call DeploymentInfo.setResourceManager() with a resource manager than can resolve the static content you want to serve, if it is just plain files on the file system you should just use PathResourceManager. I am not sure about the view resolver, it sounds like you might be missing a servlet or filter than spring expects to be configured.

Need recommendation on using embedded undertow or migrate application to use springboot's undertow

by aditya sanas

Hello Team Undertow and Stuart , Currently I m trying to create a executable jar file which would have embedded undertow configured. I was able to register controllers and dispatcher servlet to the server, but could not configure the view resolvers to return a view, such as jsp or thymeleaf. I did not found much help on configuring thymeleaf with undertow, so currently stuck. I would like to know, what you would recommend, should I continue trying to use embedded undertow server or should I migrate my current spring mvc application to spring boot. Appreciated your response. Thanks, Aditya Sanas

Configure Undertow to use ViewResolver similar to Spring MVC and serve static content

by aditya sanas

Currently I’m doing a sample project where I’m trying to configure Undertow server to use Spring MVC model. I’m able to register dispatcher servlet, context listeners, and able to configure application so that I can use spring controllers instead of servlets to process requests from browsers. So I can return JSON/XML or Plain text if I use RestController. The thing where I’m currently stuck is I’m not able to serve a static content and cannot configure a Spring’s view resolver to return a view instead of plain text. PS - I’m using Undertow as embedded server into my application and producing a standalone executable jar as a build output. Thanks, Aditya Sanas
