Error in Java Project - imported JAR

[aradhell]

Hi,
I imported jar files (socketio and engineio) from Maven to eclipse project lib but it gives no class def found error. i checked both of them on build path / export.

http://mvnrepository.com/artifact/com.github.nkzawa/socket.io-client/0.1.3
http://mvnrepository.com/artifact/com.github.nkzawa/engine.io-client/0.2.3

You need org.json 20090211 and Java-WebSocket 1.3.0 too as dependencies.

Thank you :) working very well now.

For the record, you'll also need the jar created from: https://github.com/socketio/engine.io-client-java
