Hi Ranchers,

I am trying to compile a Ajax FeedReader Application on eclipse.I downloaded the code from


This link has two folders


which I have copied in a New Project in eclipse as
two separate folders One for the sample and the other for the ajaxfeed like

com.feedReader for sample


I am trying to run this application in Development Mode.

When I try to compile the application it gives me a

Internal Compiler Error Like

java.lang.IncompatibleClassChangeError: Found class com.google.gwt.core.ext.TreeLogger, but interface was expected

Its throwing this exception for the Loader.java class in the ajaxfeed source.The following is the source for Loader.java

I am stuck since few days I know this is something very stupid...But

awating your replies experts..

Hi Ranchers,

The exception above was due to a unsupported Class built on Ajax...

Using sample package code only after removing the associations with ajaxfeed package..The application compiles successfully and gives the desired results.

I customized the application according to my organizations proprietary needs and gave it some look and feels according to the clients requirements

Its great to see that the application is very fast on Android and Blackberry phones... GWT Rocks..

What I was surprised to see was that the application fits the prescribed screen size without any change...

I would say it took me..some time...to figure it out ...But today after deploying it since last 3 months...I want to praise the effort of GWT FeedReader developers for writing such a application
