Life is full of ups and downs.
Few months back in Nov 2009, I was still in the Philippines preaching Sun Glassfish Web Space Server. (See here)
Now that Oracle has completed its acquisition of Sun, many middleware from Sun are discontinued from further development.
One product that is definitely going to be discontinued is Sun Portal Server or Sun Glassfish Web Space Server.
Oracle already own Oracle Portal Server. After the acquisition of Weblogic, it has another Portal solution in Oracle WebLogic Portal Server. These 2 products then become part of Oracle WebCenter Suite.
It simply cannot maintain another Portal solution.
So what is going to happen to existing customers using Sun Portal solutions?
Simply put: Wait for EOL, then let's upgrade you to Oracle WebCenter Suite.
Oracle WebCenter Suite datasheet can be found here.
