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>
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat7-websocket</artifactId></dependency>
</dependencies>
...
</plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId>
<configuration>
<url></url>
<server></server>
<path>/</path>
<port>7443</port>
<httpsPort>0</httpsPort>
<keystorePass>catmot</keystorePass>
<tomcatUsers>src/main/tomcatconf/tomcat-users.xml</tomcatUsers>
</configuration>
</plugin>
</plugins>
</build>
</project>
and my parent pom:
...
<dependencyManagement>
...
<dependencies>
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-catalina</artifactId><version>7.0.47</version><scope>provided</scope></dependency>
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-coyote</artifactId><version>7.0.47</version><scope>provided</scope></dependency>

<dependency><groupId>javax</groupId><artifactId>javaee-web-api</artifactId><version>6.0</version><scope>provided</scope></dependency>
</dependencies>
</dependencyManagement>
...
<pluginManagement>
<plugins>
<plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.1</version>
<dependencies>
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-catalina</artifactId><version>7.0.47</version><scope>runtime</scope></dependency>
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat-coyote</artifactId><version>7.0.47</version><scope>runtime</scope></dependency>
<dependency><groupId>org.apache.tomcat</groupId><artifactId>tomcat7-websocket</artifactId><version>7.0.47</version><scope>runtime</scope></dependency>
</dependencies> </plugin>
</plugins>
</pluginManagement>
</build>
</project>
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
] did not permit the HTTP upgrade to WebSocket
