Elastic Java Client jar throwing this error when I load from wso2

Do you have all the dependencies of the client jar? The missing class is in the server jar, which is currently a dependency.

5

Yes I do.. It is working fine when I have tested on eclipse ie...,, elastic search java client sample.. But when I placed this jar in wso2 components lib.. its throwing error while restarting.,..

am really clueless on this..

6

@rjernst: Can you be more specific ?

The elastic search java client sample is working fine with same dependencies. But, its not working when I placed it in the wso2 components/lib ... its throwing error like that in starting the server?
