time to study the code. First, you need to add an entry point to package the Java objects into an XML document. As with the Unmarshaller class, it is easiest for other programs to use packaged code from a static method. If there is no option to pass in the Java object, as d

XML configuration files. If portability is not considered, then dom4j is used.2) Jdom and Dom perform poorly during performance testing, and memory overflows when testing 10M documents. In the case of small documents it is also worth considering DOM and Jdom. Although the developers of Jdom have stated that they expect to focus on performance issues before the full release, there is really no merit in the performance point of view. In addition, Dom i
