Dynamically change width of element

I need to create table of contents in JasperReports. I have already achieved this, but cant do anything with lines in TOC.

Currently they have a static width:

Chapter 1          ........ 2
Long Chapter Name  ........ 3
End                ........ 4

I want to stretch dotted lines to the width of the chapter name. Like here:

Chapter 1 ................. 2
Long Chapter Name ......... 3
End ....................... 4

How can I do this? Is there some 'padding' functionality in JR or should I create scriptlet for this task ? Thanks!

P.S. I'm using jasper reports 5.0.1

This wouldn't be a very neat way but I would draw many dots in your text box and hide the end using a frame to allow writing the number of the page.
