Error in using WL.Client.invokeProcedure(invocationData,options,useSendInvoke)

Question

Hi i am new to worklight. When i am trying to invoke the adapter using the client side call. There is a parameter in the invoke procedure api call.The parameter is useSendInvoke .What does that mean?

Answer 1

See this question about useSendInvoke: Use of third parameter in the WL.Client.InvokeProcedure

To quote Anton:

This parameter is used internally by WL authentication framework. Technically there should not be a reason for developer to use it.

There are several ways to invoke adapters.

(1) First one is via client application. This is where you use WL.Client.invokeProcedure(invocationData, options) API.

(2) Second is by using adapter invocation service - http://pic.dhe.ibm.com/infocenter/wrklight/v6r0m0/index.jsp?topic=%2Fcom.ibm.worklight.help.doc%2Fdevref%2Fc_adapter_invocation_service.html. Basically issuing an http request to WL server and getting a response from adapter. RPC style.

When you're doing it via (1) - you have two authentication layers - first is security test defined for application, second is security test defined for adapter procedure.

When you're doing it via (2) - there is only one security layer - security test defined for adapter procedure.

UseSendInvoke param (which is, once again, for internal usage) means that your application will go via path (2) instead of regular path (1).
