              throws java.io.IOException,
                     org.apache.http.client.ClientProtocolException

Executes a request using the default context and processes the response using the given response handler.

Specified by:

execute in interface org.apache.http.client.HttpClient

Parameters:

request - the request to execute

responseHandler - the response handler

Returns:

the response object as generated by the response handler.

Throws:

java.io.IOException - in case of a problem or the connection was aborted

org.apache.http.client.ClientProtocolException - in case of an http protocol error

execute

public <T> T execute(HttpUriRequest request,
