Thrift server/client with Eclipse NoClassDefFoundError

Question

http://wiki.apache.org/thrift/Thrift%20%26%20Eclipse%20%26%20JUnit%20with%20TServlet

I followed this tutorial step by step until the part where they execute the client and the server. For the serverExample.java I added these imports.

    import org.apache.thrift.server.TServer;
    import org.apache.thrift.server.TThreadPoolServer;
    import org.apache.thrift.transport.TServerSocket;
    import org.apache.thrift.transport.TTransportException;

For the clientExample.java I added these imports:

    import org.apache.thrift.TException;
    import org.apache.thrift.transport.TTransport;
    import org.apache.thrift.transport.TTransportException;
    import org.apache.thrift.transport.TSocket;
    import org.apache.thrift.protocol.TBinaryProtocol;

When I run the server I get these errors:

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
    at org.apache.thrift.transport.TServerSocket.<clinit>(TServerSocket.java:37)

When I run the client I get these errors:

Just in case, I already added the eclipse thrift plugin. If someone could help me that would be awesome.
