Port 127.0.0.1:8888 is already is use; you probably still have another session active

Answer 1

你没有提供足够的资料,例如打分和代码。然而,我可以说的是,如果静态的初始化法放弃了暂时的例外,则会出现例外情形。请注意,该例外处理触发时间例外,因此试图查看全部的痕迹并分析。

例如:

public class Test {
    static {
        String s = "hi";
        s.substring(10);
    }

    public static void main(String[] args) {

    }
}

批量打印如下:

java.lang.ExceptionInInitializerError
Caused by: java.lang.StringIndexOutOfBoundsException: String index out of range: -8
    at java.lang.String.substring(String.java:1938)
    at java.lang.String.substring(String.java:1905)
    at Test.<clinit>(Test.java:5)
Exception in thread "main"

<>strong>-EDIT----ED

现在,你提供了更多详情,审视了与你的情况更为具体的其他答复:you要么已经开过另一场关于你的《世界展望》申请的会议,要么还有一些关于当地托管的服务器申请,在8888港听说。

Answer 3

你们还有另一场活跃的会议,其 trace痕非常明显:

[ERROR] Unable to binding socket on Port 9997 -- is another sessionactive/strong>?

java.net。 BindException: Address have in use at java.net.PlainSocketImpl.socket Bind (Nativemeth)

第127.0.0.1号:888号港已经使用;You大概还有另一场活动。

引自这一表面的最优答案:

"Even after you have exited all browser connections, the code server is still running waiting for new connections. You need to stop that connection from your previous launch before starting another one. Also, note that you don t necessarily have to restart it at all -- just make your changes and refresh the browser or launch a new browser."

From my personal experience , try launching the webapp after 1 min or so. This problem would go away. Not a clean way to do stuffs and so there is a bug filed with the GWT team for this case.
