Question

Tomcat版本：7.0.41（也尝试过8.0.32）
JRE：6u42
写了一个非常简单的JAX-WS应用程序（作为测试）。当＆＃34;？wsdl＆＃34;时，应用程序只显示wsdl文件。使用，当给出SOAP请求时，我只返回一个字符串。

@WebService
public class SOAPWithWS
{
    @WebMethod
    public String HelloTest(String sMessage)
    {
        return "Received : " + sMessage;
    }
}

当我尝试取消部署上下文时，它会给我一个警告，如下所示：

每次测试都会发生这种情况。在GlassFish服务器上也没有发生同样的事情（只是试图测试这种情况）。知道发生了什么以及如何消除这个问题吗？

您的应用程序中存在内存泄漏。查看此主题，它可能会有所帮助;

What are these warnings in catalina.out?

Answer 2

当将JAX-WS实现添加为相应项目的库时，将显示此警告。

不是将JAX-WS实现添加到项目中，而是将其添加到Tomcat本身的库列表中。例如：在Linux上，如果Tomcat安装在/ usr / java / Tomcat-7内，则JAX-WS库必须包含在/ usr / java / Tomcat-7 / lib /中。

如果不想将库直接添加到Tomcat中，请确保在取消部署上下文时完全重新启动Tomcat。如果在取消部署上下文时每次都重新启动Tomcat，则可以安全地忽略该警告。

取消部署时，Tomcat会抛出严重警告
