Hi
I asked my boss for PL/SQL programming and DB administration training. His answer was "you have strong DB skills no further training needed". That is a joke, I am a DB newbie(OCA 11g), when browsing this forum I am far away from strong DB skills.
My boss pays me training Java SE 7 Fundamentals [1Z0-803] and afterwards the next higher course [1Z0-804].
Now my question: is Java skills useful for DB dev and DBA? Does Java help me if I wish later to switch to a DB role? Is Java a useful language for DB pro?
At the moment I am programming in UNIX Shell.

Oh well. I believe that it is good to know Java. If you are going to use it.
A year ago I got the opportunity to attend 5-days Java classes for absolute beginners. The lecturer left the last day for our questions, so we asked him to create a simple master-detail "application" based on Scott's EMP and DEPT tables (that would be a simple task in Oracle Forms Builder). That poor guy spent several hours (using Eclipse, as a tool) and the result was ... huh, doubtful (we lost patience and asked him to quit). During that time, a man who sat next to me opened his Delphi IDE and created a working solution in a matter of minutes.
Therefore, I'd say that Java is good for many things. You can probably do anything you want using Java. It will work on many platforms. Quite a few "pros". One major "contra": there's nothing I could use Java for in what I currently do.
As of yourself, no idea. If your boss is willing to pay Java training(s) for you, take the chance! (You'd be stupid if you don't). It won't do any harm, but might make some good - maybe not instantly, but you can never know.

I agree.

With netbeans (another EDI) I believe I can create a JAVA application for emp and dept whitin let's say 10 minutes. That's 10 because I' not to experienced.

Indeed, it will never hurt to have some broader knowledge of applications and the way they interact with the database.
So I would take the course.

As with most programming languages, it depends on the frameworks you use. There are a lot of frameworks that simplify the creation of "Database Forms" in Java, for example in this list.
I write most of my frontend stuff in Java, and never found one that suited me, so after few years I have grown my own "in-house" frameworks to make life easier. For exable an "SQL Table" that is based on JTable and generates an editable/sortable/excel exportable/etc... JTable based on a SQL select, tailored to the data that we need to store. For example with a "Article Number Editor/Renderer" where you can not only enter an article number but also search for articles, view further article information in the tool tip etc.. and other stuff that most "general-purpose" frameworks can't do.

Of course it will be useful for you. For that matter, adding new technology skills will always be helpful.
And I firmly believe, any DB application developer should have at least basic knowledge about frontend. I have not yet worked on a left alone DB which does not have any application. Ultimately, it is the application which is developed, supported and maintained. DB tasks are backend.
