这是Catalina的最后一行。对我来说没有任何意义。我怀疑阵列可能会因为它在运行时确定而导致它，我找不到任何其他方法来做到这一点，这里的提示将不胜感激

不幸的是，即使在更改了我认为可能会抛出NPE的代码之后，它仍然没有改变任何东西。我改变了 如果（sexarra [1] == NULL）{....}
要 if（sexarra.lenght == 2）{...}
我收到以下错误：
Errore causata da: (SOAP-ENV:Protocol) :Unsupported response content type "text/html; charset=utf-8", must be: "text/xml". Response was:

答案 0 :(得分：0)
我不确定我理解你为什么要手工构建SOAP请求而不使用某种自动WSDL到类生成器，JDK，Eclipse或NetBeans附带的生成器。这将为您提供类型/结构安全性，但我肯定会在您的代码中看到问题，例如
if(sexarra[1]== null) { ... }
可能会抛出NPE或ArrayIndexOutOfBoundsException。不幸的是，Tomcat的输出对我来说也没有意义，至少不是你的问题。
