Subject Re: tomcat7-websocket - tomcat7-maven-plugin java.lang.ClassNotFoundException: javax.servlet.http.HttpUpgradeHandler
Date Thu, 07 Nov 2013 15:48:21 GMT
I think I moved forward. I changed version of javaee-web-api from 6.0 to
7.0:
<dependency><groupId>javax</groupId><artifactId>javaee-
web-api</artifactId><version>6.0</version><scope>provided</
scope></dependency>
to:
<dependency><groupId>javax</groupId><artifactId>javaee-
web-api</artifactId><version>7.0</version><scope>provided</
scope></dependency>

However now I get an error on the server side:
SEVERE: Servlet.service() for servlet [default] in context with path []
threw exception [Filter execution threw an exception] with root cause
java.lang.NoSuchMethodError:
