Issue while using Apache HttpComponents (Httpclient-4.5.jar) and other libraries in Apps deployed on

Nimanshu ParekhJul 23 2015 — edited Aug 7 2015

Hi,

We are trying to build a page and call a RightNow (Oracle Service Cloud) web service to show Incident Data on this page.

Creation of the proxy for the RightNow webservice in JDeveloper failed. The error was due to duplicate declarations and there was not much that could be done to fix that as the RightNow WSDL as it is very generic in nature.

Hence we achieved retrieving data from RightNow service by making a HTTP POST request. To achieve this, we used Libraries like httpclient-4.5

Code snippet from the java class.

this code works perfectly while the app is deployed in the local/integrated weblogic server. But when we try to deploy the application the the JCS, we are seeing some compilation failure errors as below.
