用于解决Dwr+Tomcat+Eclipse开发时报错的三个包：xalan_2_7_1.jar,serializer.jar,jdom.jar 如：Probably not an issue: org.jdom.Document is not available so the jdom converter will not load. This is only an problem if you wanted to use it.

jdom.rar - jdom 是一个处理xml文件的java类库，可以方便地对xml文件进行读或写-jdom is a processing xml file java class library, can easily read or write xml file
