Ответить Dozer is a Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types. Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping. This includes mapping collection attributes that also need mapping at the element level. Please read the about page for detailed information on Dozer - http://dozer.sourceforge.net/ The main thing we must remember working with Dozer is - valid mapping file and proper location for this. In simplest sample (using Intellij IDEA 7) we've got the part of source file: List myMappingFiles = new ArrayList(); myMappingFiles.add("beanmapping.xml"); in that case our "beanmapping.xml" must be located here: "c:\Java\Projects\ DozerTest\out\production\DozerTest\beanmapping.xml" Remember, it is - "out" directory. (path on local development machine!) In that case we can simply run the project from IDEA IDE. Sample output goes like this: C:\Java\jdk\bin\java -Didea.launcher.port=7553 -Didea.....
