--- Comment #23 from Mark Thomas <ma...@apache.org> --- Comment on attachment 33897 --> https://bz.apache.org/bugzilla/attachment.cgi?id=33897 log file with bare bones conf/web.xml Interesting. The exception is happening in the WebSocket ServletContainerInitializer. It looks to be complaining that the URL pattern is an empty string. However, the URL pattern is hard-coded to "/*". There is no more debugging logging we can enable that will shed any light on this. Some custom patches to add additional logging are going to be required. While I can provide suitable patches, shell access to a test environment would enable this to be investigated much faster. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
