*Hi,*
**
*I'm trying to make http cilent with jersey1.10.*
*I made an simple code as follows.*

Client client = Client.create();
WebResource wr =
client.resource("http://www.yahoo.co.jp/<http://www.google.com/url?sa=D&q=http://www.yahoo.co.jp/&usg=AFQjCNH8Oq_RDLTkjGHXSm_BA4I_MPqjNg>");

String result = wr.get(String.class); // NullPointerException

But I got the following error.
I use two jars.
*jersey*-client-1.10.jar
*jersey*-core-1.10.jar
How can I fix this problem?
