Greetings!
Okay, I have a JTextPane, somewhere in JTextPanes
content is a small slice of text. I know texts start
position and length. Is there some way to get x, y coordinates of
that texts start position?
And I have another question. How can I create a link between
two JScrollPanes? if I move one scroll bar down,
the other will move down as well.
Thaks, Andrey.

I'm confused a little bit. Do you want to find the location of the caret? Or do you already know where the text is in the String, and you want to find out what row and column it's on?
If it's the former, then look at the getCaretPosition() method of JTextComponent. If it's the latter, there should be a way to look at each line in the pane, and count characters until you get to the index of the substring in the original String. I don't know of any easier way.

Get the JScrollPane that the JTextPane is embedded in. Get the hor. or vert. JScrollBar from the JScrollPane. Add an AdjustmentListener to recieve events when the scroll bar is scrolled. Adjust the second Scrollbar accordingly when the first is changed. Do the same for the other scrollbar.
There are some links that talk about it here:

Thank you for your reply.
Sorry for my bad question. The position I ment is
a Java2D position(x,y). I want to put information about paragraphs
to the panel which will have exact height as JTextPane. Thats why I
need to link two JScrollPanes.
F.E. I want to get something like this:
JPanel JTextPane
Author | <author>The Smith
Text| <text> bla bla bla bla bla bla b
| bla bla bla bla bla bla bla bla
| bla bla bla bla bla bla bla bla
| bla bla bla bla bla bla bla bla
Photo| <foto>This is photo
How can I get <author>, <text> and <foto> tags "y" positions(or is it called axis?) knowing their position in the Document?
Thanks.
