tomcat中的webservice调用错误

嗯,我是grails的新手,所以我试图将Web服务称为练习,我在开发环境中工作时没有问题,但是当我尝试将war文件部署到我的tomcat 7服务器时,它只是不起作用。这是我一直在使用的代码

import org.grails.plugins.wsclient.service.WebService
//import groovyx.net.ws.WSClient

class CalculadoraController {
    WebService webService

    def index() { }

    def calcular()
    {
        def wsdlUrl = "http://www.webservicex.net/ConvertTemperature.asmx?WSDL"
        def proxy = webService.getClient(wsdlUrl)
        //def proxy = new WSClient(wsdlUrl, this.class.classLoader)
        //proxy.initialize()
        String res = proxy.ConvertTemp(params.temp,params.from,params.to)

        render res
    }
}

我尝试过使用两种方法,使用webService实例和WsClient类,但两者的结果相同。这是我从tomcat的日志中获得的堆栈跟踪:

有什么建议吗?

感谢先生,对不起我糟糕的英语
