+<overview>
+<p>
+The absence of a matching setter method for a property that is defined in a Spring XML bean causes a validation error when the project is compiled.
+</p>
+
+</overview>
+<recommendation>
+<p>
+Ensure that there is a setter method in the bean file that matches the property name. 
+</p>
+
+</recommendation>
+<example>
+
+<p>The following example shows a bean file in which there is no match for the setter method that is
+in the class.</p>
+
+<sample src="MissingSetters.xml" />
+
+<p>This is the bean class.</p>
+
+<sample src="MissingSetters.java" />
+
+<p>The property <code>transactionHelper</code> should instead have the name <code>helper</code>.</p>
