After configuration, the test runs and the following error occurs:

I found a lot of information on the Internet, said less of the JDOM package, plus the following URL of the jdom-1.0.jar package
Http://mirrors.ibiblio.org/pub/mirrors/maven/jdom/jars/jdom-1.0.jar
(Add the corresponding package,
Http://www.findjar.com/jar/jdom/jars/jdom-1.0.jar.html
Http://www.java2s.com/Code/Jar/Spring-Related/Downloadjsfapijar.htm)
the operation still encountered an error, but this time there were fewer errors. Error:

This error is really troublesome. I made a round trip on the internet, and I still couldn't find the cause of the Error. Some people say it's a problem with the xalan package. I did it, but I still can't do it, sorry, I am dead. It took several hours to waste. The last time I tried to change the doctype header file, the problem was solved. You can have a good night's sleep! The following is my correct DWR. xml file:
<? XML version = "1.0" encoding = "UTF-8"?>
<! Doctype DWR public
"-// Getahead limited // DTD direct Web remoting 1.0 // en"
