Why am I getting Error 500: java.lang.NoSuchMethodError: org/apache/http/conn/scheme/Scheme when accessing https:///rs/rootservices

After configuring the environment for Jazz reporting service and installing and deploying it on Websphere Application Server, I am unable to register it to my JTS server.
I am accessing https://<server:port>/rs/rootservices and I get
Error 500: java.lang.NoSuchMethodError: org/apache/http/conn/scheme/Scheme.<init>(Ljava/lang/String;ILorg/apache/http/conn/scheme/SchemeSocketFactory;)V

in the systemOut.log I have:
[7/30/15 14:48:25:297 EDT] 00000074 ServletWrappe E com.ibm.ws.webcontainer.servlet.ServletWrapper service Uncaught service() exception thrown by servlet RootServicesServlet: java.lang.NoSuchMethodError: org/apache/http/conn/scheme/Scheme.<init>(Ljava/lang/String;ILorg/apache/http/conn/scheme/SchemeSocketFactory;)V
