I did not copy the jar file in the WEB-INF/lib folder. I did that now but its
still the same.

There is no information related to the exception in the log file.  There are
some errors messages in eclipse which I am listing below:

1) In the HelloResource.java file, 
 For this piece of code: 
        protected Map<String, DataFormat> createSupportedFormats(Request 
request,
Response response) {

           HashMap formats = new HashMap();
           formats.put( "txt", new StringFormat( MediaType.TEXT_PLAIN ));

           return formats;
        }

These are the errors:
@ Map<String, DataFormat> Multiple markers at this line
        - The return type is incompatible with
AbstractResource.createSupportedFormats(Request, 
         Response)
        - implements org.geoserver.rest.AbstractResource.createSupportedFormats 

@HashMap Multiple markers at this line
        - HashMap cannot be resolved 
         to a type
        - HashMap cannot be resolved 
         to a type

@StringFormat and @MediaType Multiple markers at this line
        - StringFormat cannot be resolved 
         to a type
        - MediaType cannot be resolved

2)  When i start geoserver from eclipse by running the Start.java file I see
the following warning messages in the console:

Jun 22, 2009 11:14:11 AM it.geosolutions.imageio.gdalframework.GDALUtilities
