I am an old hand at cl, but java is still a bit of a mystery to me. I am particularly puzzled as to why, when trying to use the apache http components library to do a simple http get in abcl, I cannot make it work. My code: (defun http-get (url) (let* ((url (jnew (jclass "java.lang.String") url)) (client-class (jclass "org.apache.http.impl.client.DefaultHttpClient")) (client-obj (jnew client-class)) (get-class (jclass "org.apache.http.client.methods.HttpGet")) (get-obj (jnew get-class url))) (jcall (jmethod client-class "execute") client-obj get-obj))) And the java code from the apache tutorial http://hc.apache.org/httpcomponents-client-4.0.3/tutorial/html/fundamentals....: HttpClient httpclient = new DefaultHttpClient(); HttpGet httpget = new HttpGet("http://localhost/"); HttpResponse response = httpclient.execute(httpget); ... For some reason, my code fails with No such method: org.apache.http.impl.client.DefaultHttpClient.execute(). I do have the appropriate jars in my class path. The java code specifically calls the execute method on its instantiated httpclient, but I cannot do the same from abcl. This method is inherited from org.apache.http.impl.client.AbstractHttpClient, in case that makes a difference. (http://hc.apache.org/httpcomponents-client-4.0.3/httpclient/apidocs/index.ht...). Thanks for any insight! -Kevin
