In your connections navigator is there any connections there?
If you create a new connection and actually connect to the DB with that connection, Close SQL Developer and reopen it is the connection still there?
What Operating system are you on?
My operating system is windows 7.
When I add some connection and after that close sql developer and open it's again then all my connections are gone, connections navigator is empty.
I tried to change sqldeveloper.conf and delete AppData/Roaming/Sql Developer/... from user's directory.
Maybe it's jdk7 fault?

As you can see from these earlier discussions on the forum, Java 7 is not certified but some have supposedly stayed with it:
SQLDeveloper and JDK 1.7
SQL Developer 3.0 and Java SE 7?
I recommend using the latest available update in the jdk1.6.0 series instead. Normally deleting the AppData/.../SQL Developer/... folders and restarting SQL Developer fixes any problems, but perhaps this problem is some combination of Java 7 and product initialization without any migration.
Hope this helps,
