Please download the latest version of buffalo distribution. Create a directory structure as follows:
buffalo-example WEB-INF/classes WEB-INF/lib script
Copy commons-logging.jar, buffalo-version.jar to WEB-INF/lib, copy prototype.js, buffalo.js to script.
Create a web.xml in WEB-INF with content as follow:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <display-name>Buffalo Example Application</display-name> <servlet> <servlet-name>bfapp</servlet-name> <servlet-class>net.buffalo.web.servlet.ApplicationServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>bfapp</servlet-name> <url-pattern>/bfapp/*</url-pattern> </servlet-mapping> </web-app>
Create a text file buffalo-service.properties to WEB-INF/classes with content as follow:
# Example Service helloService=example.HelloService
Create example.jsp in the web root:
<html> <head> <meta http-equiv="Content-Type" content="text/html"> <title>Example::Hello</title> <script language="javascript" src="script/prototype.js"></script> <script language="javascript" src="script/buffalo.js"></script> <script language="javascript"> var END_POINT="<%=request.getContextPath()%>/bfapp"; var buffalo = new Buffalo(END_POINT); function hello() { var p1 = $("myname").value; buffalo.remoteCall("helloService.hello",[p1], function(reply) { alert(reply.getResult()); }); } </script> </head> <body> <p>Buffalo Hello World</p> <p> </p> <form name="form1" method="post" action=""> Your name: <input name="myname" type="text" id="myname"> <input type="button" name="Submit" value="Hello" onclick="hello()"> </form> </body> </html>
package example; public class HelloService { public String hello(String name) { try { // to see the loading status Thread.sleep(2000); } catch (InterruptedException e) { e.printStackTrace(); } return "Hello, " + name; } }
Compile it and copy the binary class file to WEB-INF/classes.
