I assume you mean the error is as in the subject, i.e.
Exception in thread "main" java.lang.NoSuchMethodError:
org.apache.http.impl.client.DefaultRequestDirector
Googling "NoSuchMethodError" shows that it has the following Javadoc
description:
>>>
Thrown if an application tries to call a specified method of a class
(either static or instance), and that class no longer has a definition
of that method.
Normally, this error is caught by the compiler; this error can only
occur at run time if the definition of a class has incompatibly
changed.
<<<
So are you using *exactly* the same classpath for compiling and then
running the code?
Are you sure?
