Bug ID: 56343
Summary: NPE in
org.apache.tomcat.websocket.WsWebSocketContainer.conne
ctToServer
Product: Tomcat 8
Version: 8.0.5
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: WebSocket
Assignee: dev@tomcat.apache.org
Reporter: pbieli...@gmail.com
Hi,
I believe there is a bug in
org.apache.tomcat.websocket.WsWebSocketContainer.connectToServer(Object pojo,
URI path) method in the following lines:
if (!ClientEndpointConfig.Configurator.class.equals(configuratorClazz)) {
try {
configurator = configuratorClazz.newInstance();
} catch (InstantiationException | IllegalAccessException e) {
throw new
DeploymentException(sm.getString("wsWebSocketContainer.defaultConfiguratorFail"),
e);
}
}
I don't understand why you don't like instantiating
ClientEndpointConfig.Configurator class? This is an empty / default
configurator for the endpoint which has a default constructor. Because of this
bug I had do specify explicitly a dummy configurator e.g.:
import javax.websocket.ClientEndpointConfig;
public class CustomConfigurator extends ClientEndpointConfig.Configurator {
}
@ClientEndpoint(configurator = CustomConfigurator.class)
public class ClientEndpoint {
IMHO it's useless.
Cheers,
Przemyslaw
