Once you have imported java class files on forms throgh java import class option..
it creates a pl/sql for the java class that you have imported.
names for the procedures are assigned by machine code, so dont worry about it..
for eg. if the name of a method in java class is Increment and after loading java class file the name of ur pl/sql is increment_1254.
when u call increment_1254 and pass parameter to the procedure ur class incerement will be called and desired operation will be performed.
ora_java.object is the objec that will be used to access the the class file.
as java is object oriented it requires a object to execute method of class.
so u have to initialize the object..
e.g. increment_1234 (ora_java.object,a,b) is ur procedure
to call this procedure do the following
declare
PASS ORA_JAVA.JOBJECT;
a,b integer;
begin
pass := <classname>.new;     --new will be created if ur class is public or u got public constructor in ur class.
increment_1234 (pass,a,b) ; -- increment_1234 (ora_java.object,a,b) ;
end;
