Exception in component tRESTClient

Hey Everyone,
Does the below error mean that I am missing a jar file in my configuration? 
I am trying to do a very simple task (GET, Accept Type JSON, Use Basic HTTP Authentication) using tRESTClient.
Exception in component tRESTClient_1

Re: Exception in component tRESTClient

Hi Brian,
Based on the Talend version, we need to add the javax.ws.rs.jar ( in my case I have added javax.ws.rs-api-2.0-m10.jar for the TOS 5.5.1 )  file under Talend open studio installation directory.
Mostly java library will be under *\TOS_ESB-r118616-V5.5.1\Studio\lib\java directory.
I hope it will solve your problem.

Re: Exception in component tRESTClient

tRESTClient creates exceptions reflectively, this error means that the target server endpoint is either not active or has no handler allocated to handle a given request URI
