com.endeca.navigation.ENEException: HTTP Error 404 – Navigation Engine not able to process request

I assume that you are in this page because you got the below given exception while you are querying oracle Endeca MDEX using jsp reference application or using your application code.

Here is the exception..

com.endeca.navigation.ENEException: HTTP Error 404 – Navigation Engine not able to process request ‘http://localhost:15000/search?terms=QuickCam&rank=0&offset=0&irversion=630′.
at com.endeca.navigation.OptiBackendRequest.getContent(Unknown Source)
at com.endeca.navigation.OptiBackend.getDimensionSearch(Unknown Source)
at com.endeca.navigation.HttpENEConnection.query(Unknown Source)

Cause of this exception.

There is an old version of endeca_navigation API jar sitting in your class path. I encountered this issue when I used endeca_navigation-6.3.0.jar instead of endeca_navigation-6.4.1.jar . (by mistake) You should look at <>\ToolsAndFrameworks\3.1.2\assembler\lib to find the correct version of navigation jar. The same jar shall be used in your application class path too.
