Problem in accessing Dynamics from a Java Application

Hi,

I followed the link http://msdn.microsoft.com/en-in/library/jj602979.aspx to connect to Micsrosoft Dynamic CRM from a JAVA Application.

The first error which I got was "import org.apache.http.client.HttpClient;" because it could not be resolved.

The reason for this is the library which I was asked to download from http://hc.apache.org/downloads.cgi. I went to this link and selected 4.2.5.tar.gz. I hope I have selected the right option in this link. This had only libraries like httpcore-4.2.4.jar, httpcore-ab-4.2.4.jar and httpcore-nio-4.2.4.jar.

It did not have the httpclient.jar. So then I downloaded the apache-httpcomponents-httpclient.jar from http://www.java2s.com/Code/Jar/a/Downloadapachehttpcomponentshttpclientjar.htm because this is the only place I got the Client jar. It is not inside  http://hc.apache.org/downloads.cgi

Then the errors were gone.

But when I run the app it says: 

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/protocol/ImmutableHttpProcessor

The line which is throwing the error is:

        SecurityData discoverySecurityData = discoeryTokenManager.authenticate(DiscoveryServiceURL, 
                    UserName, 
                    UserPassword,
                    discoveryPolicy.getAppliesTo(),
                    discoveryPolicy.getPolicy(),
                    discoveryPolicy.getIssuerUri());



Please help Me!!!
