java.lang.ClassNotFoundException: org.apache.http.HttpEntity

Hie

In my gwt+gae  app when running i am seeing below exception. the class in question is a part of gwt-dev.jar which is included in classpath (otherwise i think there will be many issues even before this).

Any advise why I am getting the error on runtime even when the jar is a part of class path?

looks like u want to use apache-httpclient for gae

1. not all jdk-packages are useable in gwt-clientside
2. limitations of gae : networkconnections (outbounds ) ???

[Vik]

its in local dev mode and using gwt 2.3.0

Thankx and Regards

yeah i m importing classes like import org.apache.http.HttpEntity; 

Using these to call a rest ws . so what is the option to do it on GWT+GAE platform. Just to mention i am invoking this code from server side i.e from a serviceImpl 

Thankx and Regards

not sure what you want to achieve, but for client-side http, have a look at RequestBuilder .
never use gae so i cannot tell what options u'd have there
