    copied!<p>Try using <code>test.B$C</code> like in the following example:</p> <pre><code>&lt;mapping wildcard="false" map-null="false" map-id="test"&gt; &lt;class-a&gt;test.A&lt;/class-a&gt; &lt;class-b&gt;test.B$C&lt;/class-b&gt; &lt;field&gt; &lt;a&gt;fielda1&lt;/a&gt; &lt;b&gt;fieldc1&lt;/b&gt; &lt;/field&gt; &lt;field&gt; &lt;a&gt;fielda2&lt;/a&gt; &lt;b&gt;fieldc2&lt;/b&gt; &lt;/field&gt; &lt;/mapping&gt; </code></pre> <p>Also note that I changed the second field from <code>fielda1</code> to <code>fielda2</code>, it appeared to be a typo in your example.</p> <p><strong>Note:</strong> Because you set <code>map-id="test"</code> you must include <code>mapId</code> when you call map, like in:</p> <pre><code>B.C destObject = mapper.map(a, B.C.class, "test"); </code></pre> <hr> <p>I tested and this is working correctly:</p> <p><strong>A.java</strong></p> <pre><code>package com.test; public class A { private String fielda1; private String fielda2; public String getFielda1() { return fielda1; } public void setFielda1(String fielda1) { this.fielda1 = fielda1; } public String getFielda2() { return fielda2; } public void setFielda2(String fielda2) { this.fielda2 = fielda2; } } </code></pre> <p><strong>B.java</strong></p> <pre><code>package com.test; import java.util.List; public class B { private List&lt;C&gt; cList; public List&lt;C&gt; getcList() { return cList; } public void setcList(List&lt;C&gt; cList) { this.cList = cList; } public static class C { private String fieldc1; private String fieldc2; public String getFieldc1() { return fieldc1; } public void setFieldc1(String fieldc1) { this.fieldc1 = fieldc1; } public String getFieldc2() { return fieldc2; } public void setFieldc2(String fieldc2) { this.fieldc2 = fieldc2; } } } </code></pre> <p><strong>mapping.xml</strong></p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;mappings xmlns="http://dozer.sourceforge.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://dozer.sourceforge.net http://dozer.sourceforge.net/schema/beanmapping.xsd"&gt; &lt;mapping wildcard="false" map-null="false" map-id="test"&gt; &lt;class-a&gt;com.test.A&lt;/class-a&gt; &lt;class-b&gt;com.test.B$C&lt;/class-b&gt; &lt;field&gt; &lt;a&gt;fielda1&lt;/a&gt; &lt;b&gt;fieldc1&lt;/b&gt; &lt;/field&gt; &lt;field&gt; &lt;a&gt;fielda1&lt;/a&gt; &lt;b&gt;fieldc2&lt;/b&gt; &lt;/field&gt; &lt;/mapping&gt; &lt;/mappings&gt; </code></pre> <p><strong>Main.java</strong></p> <pre><code>package com.test; import java.util.ArrayList; import java.util.List; import org.dozer.DozerBeanMapper; import org.dozer.Mapper; public class Main5 { public static void main(String[] args) throws Exception { List&lt;String&gt; mappingFiles = new ArrayList&lt;String&gt;(1); mappingFiles.add("mapping.xml"); Mapper mapper = new DozerBeanMapper(mappingFiles); A a = new A(); a.setFielda1("fielda1Value"); a.setFielda2("fielda2Value"); B.C destObject = mapper.map(a, B.C.class, "test"); System.out.println(destObject.getFieldc1()); System.out.println(destObject.getFieldc2()); } } </code></pre> <p>This outputs in the console:</p> <pre><code>... fielda1Value fielda1Value </code></pre>
