java.lang.NoClassDefFoundError: com/google/gwt/core/shared/GWTBridge -

i'm not sure why java.lang.noclassdeffounderror: com/google/gwt/core/shared/gwtbridge on line 60 of home.java.

steps reproduce:

1. clone jenterprise , open jenterprise , helloworld projects
2. build jenterprise helloworld
3. run helloworld -> com.jenterprise.examples.helloworld.begin
4. go to: http://localhost:8090/examples/helloworld/home

what i'm trying use onmoduleload() update interface after executing other logic in method use forward(request, response) show interface, i.e.

public void main(httpservletrequest request, httpservletresponse response) {         system.out.println("running home: main(httpservletrequest request, httpservletresponse response)");         onmoduleload();         request.getrequestdispatcher("/index.jsp").forward(request, response); } 

onmoduleload() entrypoint method, part of client-side gwt code compiled gwt compiler. can't use server-side.
