I'm working on an app maven java using websphere server 8.5 and elasticsearch 5.4

this is all my dependencies for ES 5

[
org.elasticsearch.client
transport
5.4.1


org.apache.logging.log4j
log4j-api

I when I start my server (of course es 5 is already started on 9200 localhost) I got this error

Please format your code using </> icon as explained in this guide. It will make your post more readable.

Or use markdown style like:

```
CODE
```

1st of all I'd use the Rest client instead of the Transport client.
Then, could you try you sample code outside the context of websphere?

May be share also your sample code?

3

when I tried my code in a separate project (main class) it work fine

4

May be a jar conflict with existing libs in websphere?
Log4j?
