ADF/TopLink/Struts - start browsing from a given row position?

Question

I created a web-application to browse a table called "Project" in the database using ADF/TopLink/Struts, following some online tutorials, and successfully deployed it to Tomcat 5.5.7. Now I am able to browse the table using the following link,
http://localhost:8080/Project/browseProject.do
Since there are too many data records in the table, I am wondering if there is a way to jump to a given row using something like,
http://localhost:8080/Project/browseProject.do?Project_ID_No=123
where "Project_ID_No" is the primary key of table "Project".
I understand that we can retrieve the value of the "Project_ID_No" parameter from the HttpServletRequest. The question is how to obtain the currency corresponding to the value of "Project_ID_No" and perform some necessary steps afterwards?
Thanks,
Henry

Sorry I haven't been able to reply, got dragged into an emergency project.
I have it all working very well, and I really should have figured the commit thing out myself, I was just thinking about it way too hard.
I do have one more quick question about something I was able to do, I want to have a link next to each row that will delete that row. In order to do that I need to:
1) Set the current row
2) Delete the row
3) Commit
I was able to do this declarative without having to create any extra data actions by passing three event params on a link such as the following
<a href="engineManagement.do?event=selectRow&rowKeyStr=<c:out value='${Row.rowKeyStr}' />&event=Delete&event=Commit" >Delete</a>
(selectRow is bound to the setCurrentRowWithKey method)
Should I be using the event system in this way?
This seems to work very well, but i'm concerned about the ordering of the events, if they get executed in the wrong order, the wrong row will be deleted or the transaction won't get committed. Will the ADF controller always execute events in the order they appear on the query string?
