 The constructor can't be passed to \code{JAVA:JCALL}, but instead should
 be passed as an argument to \code{JAVA:JNEW}.

+\subsubsection{Accessing Java object fields}
+
+Fields in Java objects can be accessed using the getter and setter functions
+\code{JAVA:GETFIELD} and \code{JAVA:PUTFIELD}. This applies to values stored in object
+instances. If you want to access static fields: see the next section.
+
+Like \code{JAVA:JCALL} and friends, values returned from these accessors carry
+an intended class around and values which can be converted to Lisp values will
+be converted.
+
+\subsubsection{Accessing Java static fields}
+
+Static fields in Java objects (class fields) can be accessed using the getter
+and setter functions \code{JAVA:GETSTATIC} and \code{JAVA:PUTSTATIC}. Values
+stored in object instance fields can be accessed as described in the previous
+section.
+
+Like \code{JAVA:JCALL} and friends, values returned from these accessors carry
+an intended class around and values which can be converted to Lisp values will
+be converted.
