Question

我有一个使用elasticsearch官方java客户端的Web应用程序。在使用IBM JVM Java 7在Websphere 8.5.5上使用该Web应用程序时，我收到以下错误。我尝试使用传输客户端和节点客户端。还尝试使用Oracle JavaSE 7和8作为Elasticsearch的JVM。但没有成功。 Elasticsearch不在IBM JVM上运行，而Websphere仅在IBM JVM上运行。

有没有人知道从Websphere上的应用程序使用elasticsearch官方java客户端的方法？

以下是错误堆栈跟踪：

此问题的唯一解决方法是为两个Java应用程序使用相同的JVM。使用不同更新版本的相同 JVM之间的Java异常序列化可能不一致，显然这是IBM的JVM与您使用Elasticsearch运行的JVM之间的问题。

具体来说，Elasticsearch不能在IBM JVM上运行，因为IBM JVM has bugs in it that prevent it from working correctly。

幸运的是，前景在这里变得更好。 IBM is working with Elasticsearch to get it working properly 和 Elasticsearch is removing serialization in Elasticsearch 2.0。
