How to create combobox to display more than one columns

Question

I need kind help with the following question. As the combobox includes two pieces--textbox and the combobox list. Then how to create a combo box bean, which is based on table EMP(empno number(6), ename varchar2(40)) records for example, to achieve these features:
1) allow more than one columns to be displayed in its records list--e.g., I need to show these records:
empno (value) ename (label)
103 David M Baker
104 David M Baker
105 Kelly J Volpe
106 Krista F Carpenter
107 Michelle P Silverman
The two 'David M Baker's are different employees, but unfortunately, with the same name.
2) allow combo box list to return the column value 'empno' even though it shows both columns as above. i.e., if user picks the second record above, then the combobox list returns 104 to the textbox in the background, but the 'David M Baker' is displayed on the textbox. Of course the combobox list may return 'David M Baker' if needed when there is only one column in the list as the current standard feature.
3)allow partial match search by typing in some letters. i.e., if user types in the textbox of the combobox letter 'K' or 'k' then the partially matched records
105 Kelly J Volpe
106 Krista F Carpenter
should be automatically displayed in the combobox list, not the whole list as above; then user may double click to choose one of the two or if user continues to type in 'R' or 'r', then the uniquely matched record 'Krista F Carpenter' is displayed in the textbox and the 106 is returned to the textbox.
4) as a bonus if it's doable, allow combobox to return values to different textboxes when its records list has more than one columns.
The reason I need these features is that I am working on the project migrated from Microsoft Access applications to centralized Java version web application. We at beginning promised to users community that Java swing will provide all the GUI user friendly features Microsoft Access has, but now we got stucked--we ate our words and got tons of complains from our users community. This is just the most needed component I posted here. I really hope that Java would add all the default GUI user-friendly features to compete with MS since its Win95 GUI has been accepted as industry standard. And most users are used to it. They claimed that they don't know and don't care what tool you use the newly created application should be more user friendly, not the opposite.
I would be very much appreciated if any one would help me with this item.

Thanks for your comments. I think nobody expects Sun to write everything including special features for its components. But I do think Sun should provide at least those standard user-friendly features for the GUI components because most users have been used to the GUI user-friendly features provided by Win95 and Access/Excel applications. Then this will help us to productively create applications to beat MS applications.
Other wise like me, to get the existing GUI features, existed in old MS Access application, for our migrated Java application, I must re-create the GUI components library first which is a big burden to me at least, for others it might be fun for coding on their own from scratch, but I have to focus on the timing of project.
If you really can pass the request to Sun and push them move a bit, please pass these words: before Sun starts to revise them, please play around window GUI, e.g., Access/Excel applications, then plan what to do, the bottom line is to equally match or better than them in FUNCTIONALITY(Look and feel is not my focus here). Don't ignore the influence of Windows regardless of you hate it or love it, the reality is most users are so familiar with windows GUI features which are accepted as industry standard. Thus the choice is to match or better to beat them. Don't make your car by closing your door, don't assume users will like what you come out in a closed room.
