配置一个最简洁的DWR
期工作:
1.dwr官网下载dwr.jar(http://directwebremoting.org/dwr/downloads/index.html)
2.将dwr.jar放在自己的lib目录下(同时引入commons-logging.jar,可能适合dwr记录日志有关系,在下边的zip中lib目录中可以找到)。
3.编辑web.xml,加入如下代码:
?6 测试dwr是否配置成功http://localhost:8080/webapp名称/dwr/index.html
例如我的:http://localhost:8080/emss/dwr/index.html,
如果页面出现
Classes known to DWR:Test (com.Test):字样,恭喜你,dwr配置成功了。
点击Test,进入dwr调试页面,从页面可以看到当前Test的配置信息为(这些信息是需要引入到jsp页面的):
<!-- These paths use .. so that they still work behind a path mapping proxy. The fully qualified version is more cut and paste friendly. -->
Methods For: Test (com.Test)To use this class in your javascript you will need the following script includes:
<script type='text/javascript' src='/emss/dwr/interface/Test.js'></script> <script type='text/javascript' src='/emss/dwr/engine.js'></script>In addition there is an optional utility script:
<script type='text/javascript' src='/emss/dwr/util.js'></script>?
