Error trying to execute SimpleEchoClient
Hi! I get the next exception when I execute SimpleEchoClient or RosTest:
Exception in thread "main" java.lang.NullPointerException at org.eclipse.jetty.websocket.common.extensions.AbstractExtension.getName(AbstractExtension.java:90) at org.eclipse.jetty.websocket.api.extensions.ExtensionFactory.
(ExtensionFactory.java:37) at org.eclipse.jetty.websocket.common.extensions.WebSocketExtensionFactory. (WebSocketExtensionFactory.java:40) at org.eclipse.jetty.websocket.client.WebSocketClient. (WebSocketClient.java:85) at org.eclipse.jetty.websocket.client.WebSocketClient. (WebSocketClient.java:78) at tests.SimpleEchoClient.main(SimpleEchoClient.java:18)
Thank you!
I'm going to guess it's something to do with Jetty not having all the libraries that it needs... It's trying to load an extension and failing. Is Jetty installed correctly? Your classpath set up? Have you tried looking on Jetty forums?

It was a weird conflict between different versions of Jetty, now it's solved. Thank you! :smile:
