The adapter software is installed, see Installation tasks.
When you installed the adapter, you installed it into an existing JTS server installation. That JTS server can be running on an Apache Tomcat application server or a WebSphere Application Server. The adapter web application was placed into one of those application servers for later deployment.
If your JTS is running the Apache Tomcat or WebSphere Application Server, set up the Tomcat server or the WebSphere Application Server.
