Of course, don't expect to find anything readable in the Oracle documents, they are made 90% of "if you want to know something about this, follow this link" , or just a dry list of standards, all in a completely unemotional language that puts you immediately to sleep. But their JEE7 Tutorial is quite decent, however it's only meant for Glasshfish development.
Here also plenty of short tutorials https://apexapps.oracle.com/pls/apex/f?p=44785:OLL_SEARCH:116956567220019:::2:P2_SEARCH_TEXT:Weblogic
And of course all the OracleWeblogic youtube videos https://www.youtube.com/user/OracleWebLogic/videos
