Discovering Web Applications

The application discovery feature enables you to discover (retrieve the list of applications) from an application server, and import them as proxy applications in a few steps. All the necessary default settings are pre-populated by the discovery system so that you do not need to manually enter the information.

Configuring WSO2 Application Server permissions

Follow the steps below to provide a set of minimal permissions to query WSO2 AS and retrieve the applications hosted in it.

1. Download WSO2 AS, and start the server. For instructions on starting WSO2 AS server, see Getting Started.

   Change the value of the <Offset> element in the <AS_HOME>/repository/conf/carbon.xml file, to set a port offset to the default WSO2 AS port. This prevents port conflicts that occur when you start more than one WSO2 products on the same server. 

2. Create a user role in WSO2 AS with the following permissions as follows. For instructions on creating a user role in WSO2 AS, see Configuring Users and Roles.
   
3. Create a user by assigning the role created in the above step.
