+Java* Objects
+-------------
+
+.. class:: JavaClass
+
+    Base for reflecting a Java class. The idea is to subclass this JavaClass,
+    add few :class:`JavaMethod`, :class:`JavaStaticMethod`, :class:`JavaField`,
+    :class:`JavaStaticField`, and you're done.
+
+    You need to define at minimun the :data:`__javaclass__` attribute, and set
+    the :data:`__metaclass__` to :class:`MetaJavaClass`.
+
+    So the minimun class definition would look like::
+
+        from jnius import JavaClass, MetaJavaClass
+
+        class Stack(JavaClass):
+            __javaclass__ = 'java/util/Stack'
+            __metaclass__ = MetaJavaClass
+
+    .. attribute:: __metaclass__
+
+        Must be set to :class:`MetaJavaClass`, otherwise, all the
+        methods/fields declared will be not linked to the JavaClass.
+
+    .. attribute:: __javaclass__
+
+        Represent the Java class name, in the format org/lang/Class. (eg:
+        'java/util/Stack')
+
+    .. attribute:: __javaconstructor__
+
+        If not set, we assume the default constructor to take no parameters.
+        Otherwise, it can be a list of all possible signatures of the
+        constructor. For example, a reflection of the String java class would
+        look like::
+
+            class String(JavaClass):
+                __javaclass__ == 'java/lang/String'
+                __metaclass__ = MetaJavaClass
+                __javaconstructor__ == (
+                    '()V',
+                    '(Ljava/lang/String;)V',
+                    '([C)V',
+                    '([CII)V',
+                    # ...
+                )
+
+.. class:: JavaMethod
+
+    Reflection of a Java method.
+
+    .. method:: __init__(signature, static=False)
+
+        Create a reflection of a Java method. The signature is in the JNI
+        format. For example::
+
+            class Stack(JavaClass):
+                __javaclass__ = 'java/util/Stack'
+                __metaclass__ = MetaJavaClass
+
+                peek = JavaMethod('()Ljava/lang/Object;')
+                empty = JavaMethod('()Z')
+
+        The name associated to the method is automatically set from the
+        declaration within the JavaClass itself.
+
+        The signature can be found with the `javap -s`. For example, if you
+        want to fetch the signatures available for `java.util.Stack`::
+
+            $ javap -s java.util.Stack
+            Compiled from "Stack.java"
+            public class java.util.Stack extends java.util.Vector{
+            public java.util.Stack();
+              Signature: ()V
+            public java.lang.Object push(java.lang.Object);
+              Signature: (Ljava/lang/Object;)Ljava/lang/Object;
+            public synchronized java.lang.Object pop();
+              Signature: ()Ljava/lang/Object;
+            public synchronized java.lang.Object peek();
+              Signature: ()Ljava/lang/Object;
+            public boolean empty();
+              Signature: ()Z
+            public synchronized int search(java.lang.Object);
+              Signature: (Ljava/lang/Object;)I
+            }
+
+.. class:: JavaStaticMethod
+
+    Reflection of a static Java method.
+
+.. class:: JavaField
+
+    Reflection of a Java field.
+
+    .. method:: __init__(signature, static=False)
+
+        Create a reflection of a Java field. The signature is in the JNI
+        format. For example::
+
+            class System(JavaClass):
+                __javaclass__ = 'java/lang/System'
+                __metaclass__ = MetaJavaClass
+
+                out = JavaField('()Ljava/io/InputStream;', static=True)
+
+        The name associated to the method is automatically set from the
+        declaration within the JavaClass itself.
