The first task for configuring Business Space widgets to work in WebSphere® Portal is to set up single sign-on (SSO) with WebSphere Portal and your Business Space server and to make sure the Secure Sockets Layer (SSL) certificates are exchanged between the servers for WebSphere Portal and Business Space.
If WebSphere Portal and your product (WebSphere Business Modeler Publishing Server, WebSphere Process Server, or WebSphere Enterprise Service Bus) reside in separate cells, you must configure single sign-on between the two servers.
Your product offers Representational State Transfer (REST) APIs that can be accessed through the REST gateway. By default, the REST gateway is configured to accept only HTTPS connections. Because some widgets access these REST APIs, WebSphere Portal requires the SSL certificate imported from your product.
For the servers for both WebSphere Portal and your product, you must use the same user name and password to log on to the administrative console.
