Question

i am using httpclient-4.1.2 jar file in my project,and write code:

HttpClient client = new DefaultHttpClient();

but its throwing an exception

Exception in thread "main" java.lang.VerifyError: (class: org/apache/http/impl/client/DefaultHttpClient, method: setDefaultHttpParams signature: (Lorg/apache/http/params/HttpParams;)V) Incompatible argument to function

Answer 1

You have to have the other jars for the httpclient as well (httpcore for example, a lots of the apache commons as well).

Answer 2

The parameter "HttpParams" is in fact an interface which needs to be sent as parameter to setDefaultHttpParams .

Are you constructing this and is it being sent? In order to send it, you need to have some other jar, and this is the problem.
