In this blog post, we will; Talk to a WS-Addressing enabled service which is hosted in WSO2 Application Server using SOAPUI Assert response SOAP message to validate WS-A headers Pre-requisites: 1. Download and install the free version of SOAPUI 3.0.1 or later 2. Download and install WSO2 Application Server 4.0 Step 1 We are going to invoke the default HelloService which is shipped with WSO2 Application Server. Go to WSO2_APPSERVER/home/bin and start the server by running{ba
