当我尝试从使用部署在 tomcat 7 上的 GWT 编写的服务器 java 调用 Web 服务时，出现此错误：

如果我部署在另一个应用程序服务器（如码头）上，我没有错误。tomcat 有什么问题？

这是调用 Web 服务的代码：

static String skosClassifier(String repository,String message) throws AxisFault {
    RPCServiceClient serviceClient = new RPCServiceClient();
    Options opt = serviceClient.getOptions();
    opt.setTo(targetEPR);
    QName opEcho = new QName("http://service.project.me","skosClassifier");
    BufferedReader console=new BufferedReader(new InputStreamReader(System.in));
    try{
        Object[] opEchoArgs=null;
        Class[] returnTypes=new Class[]{String.class};
        Object[] response=null;
        opEchoArgs=new Object[]{repository,message,false};
        response=serviceClient.invokeBlocking(opEcho, opEchoArgs, returnTypes);
        String returnValue = (String)response[0];
        return returnValue;
    } catch (Exception e){
        e.printStackTrace();
    }
    return "SERVER ERROR";

我正在查看显示 NumberFormatException 的堆栈跟踪。

查看文件 HTTPProxyConfigurationUtil（我正在检查axis2-1.6.2），该行正在解析代理端口。下面是相关代码。

String port = System.getProperty(HTTP_PROXY_PORT);
        if(port != null) {
            proxyPort = Integer.parseInt(port);
        }

您是否为 HTTP_PROXY_PORT 设置了有效的整数值？您需要检查传递给 JVM 的参数。

请检查web.xml标题是否正确。通常错误是通过web.xml.
