I have the following controller:




And when I use it like this to display the contents in a display table on JSP/HTML, it works fine:


So I can see a list of file names under :Cleanup File column and similar for coment and Ready column.

Instead of displaying them in the table, I want to have it displayed as a list. So I was trying something ike this:



But it doesn't displays file names in the dropdown list. Do I need to have form tag and have everything inside form to achieve this?

HTML select elements are largely un-stylable. What are you trying to achieve?

P.S. If you want to get fancy with CSS and are targeting only modern browsers, here's an article that might be helpful.

I would like to display all the filenames in a dropdown list. It works fine in case of display table as I mentioned but I am little confused how to make it work for select options tag of HTML

Your HTML for the select element should contain only options elements, and optionally optgroup and hr elements.

The only thing in the dropdown I see is "--Please Select--" which is hardcoded by me. It's not displaying anything related to "cleanupFile.fileName" in the dropdown list. Anything wrong I'm doing to display this?

I revised my post. You'd need to loop through your list and create an option element for each choice.

Can you show me an example? I mean I know how to do it via jQuery and Javascript but I am wondering in JSP, how would I figure out upto what length I need to loop etc. Thanks!

That depends on what tag library you are using. It will likely have tags for looping over a list or array of data.

Then you would use <c:forEach> to iterate over your data.

Thanks. I modified my code to use that and it looks like this:



Could you take a look and see if it is looking fine?

Does the class CleanupFileWrapper have a method like getFileName()?  Can you show the declaration of the field you're attempting to access, and its getter?

CleanupFileWrapper has following declarations inside it:



The getFileName() is defined inside CleanupFile. So I guess I am trying to access it correctly in my JSP if I do it like this : cleanupFile.fileName , cleanupFile.cleanupFileId ?




Similarly, when I tested the following:



I ended up getting the error:



Seems like it's not going one more level deep or I'm accessing it incorrectly?

The error message suggests that the thing you're calling a "cleanupFile" is actually a CleanupFileWrapper.  And from your code, CleanupFileWrapper has a property named cleanupFile, not cleanupFileId.  And what you really want is the fileName inside the CleanupFile which is inside the CleanupFileWrapper.  So I think you need something like this:
