I followed this tutorial but when I try to access the listServices page I'm getting a 500 error.
java.lang.NoClassDefFoundError: org/apache/http/HttpResponseFactory org.apache.axis2.transport.http.SimpleHTTPServer.init(SimpleHTTPServer.java:116) org.apache.axis2.engine.ListenerManager.init(ListenerManager.java:74) org.apache.axis2.transport.http.AxisServlet.init(AxisServlet.java:449) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:849) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:454) java.lang.Thread.run(Thread.java:619)
Any ideas?
