I have added <inherits name="com.google.gwt.json.JSON" /> in
multisearch.gwt.xml file and that problem solved
but now I am getting these errors

[ERROR] Line 22: Expected a valid parameter type signature in
JSNI method reference
>
obj.@com.example.multisearch.client.JSONRequestHandler::onRequestComplete(
>
---------------------------------------------------------------------------
^

this is the code i have written

private native static void createCallbackFunction(
JSONRequestHandler obj, String callbackName )/*-{
tmpcallback = function( j ){
obj.@com.example.multisearch.client.JSONRequestHandler::onRequestComplete(
Ljava/lang/String;)( j );
};
eval( "window."+callbackName+"=tmpcallback" );
}-*/;


class name is
correct(com.example.multisearch.client.JSONRequestHandler),method also
correct and its parameter also correct but still it generating
error.pls help me

JSNI references must be on a single line; there cannot be new lines between the '@' and the ')'. I haven't checked but actually it might even choke on spaces.
