I have a servlet which provides a hyperlink to another servlet in which processing pertaining to the hyperlink in the former takes place.Each hyperlink is dynamically generated and is given a unique identity so that it can be acessed in the processing servlet.How do i set a unique identification in the <a href> tag in the first servlet and how can i access the same in the target servlet?
Thanks,

If you generate a timestamp and embed it in the url as a querystring variable, you can retrieve it with request.getParameter("timestamp");

I not sure what you mean by
access the value of a hyperlink (<ahref> tag)
A servlet or JSP writes an HTML page that has HTML tags (including hyperlinks) in it. A hyperlink URL can contain request parameters that appear in a GET request just like form parameters would appear.

You may try this

This will make multiple requests to process the block sequentially and you can get uniqueId.
