tomcat7-websocket - tomcat7-maven-plugin java.lang.ClassNotFoundException:
javax.servlet.http.HttpUpgradeHandler
Hello,
I am migrating my websocket application to the new API with version 7.0.47.
How can correctly make a configuration of tomcat7-maven-plugin to use
tomcat7-websocket on localhost.
Here what I have in my pom:
...
<dependencies>
...
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-catalina</artifactId></dependency>
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-coyote</artifactId></dependency>

</plugin>

</project>
and my parent pom:

When using simple server end point
@ServerEndpoint(value="/connector")
public class MachineWsConnector {
@OnOpen
public void onOpen(Session session) { }
@OnClose
public void onClose(Session session, CloseReason closeReason) { }
}
and trying to connect with client with:
WebSocketContainer container = ContainerProvider.getWebSocketContainer();
container.connectToServer(Client.class, new
URI("ws://localhost:7443/connector"));
I get error on client side:
Exception in thread "main" javax.websocket.DeploymentException: The HTTP
response from the server [HTTP/1.1 500 Internal Server Error

Re: tomcat7-websocket - tomcat7-maven-plugin java.lang.ClassNotFoundException:
javax.servlet.http.HttpUpgradeHandler
Posted by Marek Jagielski <ma...@gmail.com>.
In tomcat's svn history I see that looked method was added to InstanceManager
(tomcat-api) when Back-porting JSR-356:
+ public Object newInstance(Class<?> clazz)
+ throws IllegalAccessException, InvocationTargetException, NamingException,
+ InstantiationException;
+
However, I solved the problem by adding explicitly
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-api</artifactId><version>7.0.47</version><scope>runtime</scope></dependency>
into <pluginManagement> <dependencies>
I hope that this topic can be at least useful for others.
Thanks,
Marek
Re: tomcat7-websocket - tomcat7-maven-plugin java.lang.ClassNotFoundException:
javax.servlet.http.HttpUpgradeHandler
Posted by Marek Jagielski <ma...@gmail.com>.
While debuging I see that
httpUpgradeHandlerClass in upgrade of org.apache.catalina.connector.Request
is
class org.apache.tomcat.websocket.server.WsHttpUpgradeHandler
InstanceManager is org.apache.catalina.core.DefaultInstanceManager
in the source code of my maven dependency of tomcat-api-7.0.47 this method
should exist:
public interface InstanceManager {
public Object newInstance(Class<?> clazz)
throws IllegalAccessException, InvocationTargetException,
NamingException,
InstantiationException;
...
Any clue ?

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:
