What I mentioned is generic, :myvariable can be a bind variable of ANY language or tool that accepts to pass a variable to a SQL statement.
Here's an example with SQL*Plus (and don't tell me your field is filled by a trigger and mine is not, there is no difference):
SQL> var myvar number
SQL> insert into t values(10) returning col into :myvar;
1 row created.
SQL> print myvar
MYVAR
----------
10
Regards
Michel

Bind a variable to the statement.
You should (most probably) also use a bind for the value you are inserting (unless your app should only ever insert a single value)

I expected this question, so I googled for the following terms: java bind variables
A list of very useful links was returned for those VERY obvious searchterms!
