1. Put the package of DWR mainly dwr.jar; (copy the package in the Demo WAR in DWR to your application), there is another Xalan.jar package (this package is not included in the DWR Demo WAR) Copy to the application's web-inf / lib directory 2. Modify the web.xml file, which is as follows: Code:
XMLns = "http://java.sun.com/xml/ns/j2ee"
XMLns: xsi = "http://www.w3.org/2001/xmlschema-instance"
XSI: SchemAlocation = "http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd ">
DWR-Invoker
DWR Servlet
Direct Web Remoter Servlet
Org.directWebremoting.Servlet.dwrServlet
debug
True

DWR-Invoker
/ dwr / *
3. Write the dwr.xml file to save the code with the same directory with Web.xml:
Value = "com.ceun.demo" />
4. Write com.ceun.Demo class code:
Package com.ceun;
Public class demo {
Public string hello () {
Return "Hello";
}
}
5. Write JSP code:
<% @ page language = "java" PageEncoding = "GB2312"%>
