Question

尝试从同一浏览器中的多个选项卡登录时，

icCube IDE会引发异常。你知道可能是什么原因吗？

清除Cookie会有所帮助，但这是一种非常不舒服的解决方法。

IDE显示一个带有AUTHENTICATIONERROR：

的弹出窗口

com.google.gwt.user.client.rpc.StatusCodeException: 500 The call failed on the server; see server log for details

服务器日志显示异常：

如果您在同一个网址上共享多个icCube的等值（不同的端口是不够的），您将与JSESSION Cookie发生冲突。这两个URL很可能会发生冲突：

  myIcCube.myCompany.com:8282/icCube/icCube.html
  myIcCube.myCompany.com:8283/icCube/icCube.html

对于此设置，您需要取消注释icCube.xml文件的webApp部分，以使其在您的服务器中唯一。例如，对于8282服务器：

<webApp>
        <!--
            An example showing how to change the name of the JSESSIONID cookie; handy for example
            when having icCube part of a complex Web App (e.g., behind a proxy).
        -->
                <context-param>
                    <param-name>org.eclipse.jetty.servlet.SessionCookie</param-name>
                    <param-value>IC3_JSESSIONID_8282</param-value>
                </context-param>
                <context-param>
                    <param-name>org.eclipse.jetty.servlet.SessionIdPathParameterName</param-name>
                    <param-value>ic3_jsessionid_8282</param-value>
                </context-param>
    </webApp>

重新启动服务器后应该没问题（我们的测试服务器上也存在此问题）。

这也是改变icCube默认JSESSION的好方法，以防你在基于Java Servlet的Web服务器之后。
