WSO2 BAM REST-API示例執行

Question

我在Windows 7和Cygwin 1.7.18上安裝了WSO2BAM V2.2.0。 當我嘗試運行REST-API示例時，在BAM控制台中出現以下錯誤。
誰能讓我知道可能出什么問題以及如何解決該問題？

Answer 1

我不確定，但是請查看您的Java版本是否為JDK 1.7。 如果是這樣，請更改為JDK 1.6。

Answer 2

此問題不應歸因於Cygwin問題或通過rest API將數據發布到BAM時。 並行運行多個Hive腳本時，似乎已經出現了此問題。 遇到此問題時，您安裝了多少個工具箱？

Answer 3

請嘗試在linux中進行配置，它可能會起作用。
