DWR错误汇总

原因是,没传参数

function add(num){

 

}

 

javascript:add();

 

data is null错误 原因是 dwr.xml没有配置convert(返回值的convert)

 

A server error has occurred

解决办法：log4j关于dwr的配置 .我也不知道该是哪个全设置成Debug.然后看后台报错信息。我的是找不到类。

log4j.logger.org.directwebremoting=DEBUG

# Set this to DEBUG to see what's happening on startup
log4j.logger.org.directwebremoting.log.startup=DEBUG

# Set this to DEBUG to see the created scripts
log4j.logger.org.directwebremoting.log.scripts=DEBUG

# Set these to DEBUG to see session lifecycle information
log4j.logger.org.directwebremoting.log.session=DEBUG

log4j.logger.org.testdwr=DEBUG
log4j.logger.org.springframework=DEBUG
