How to pass values for the checkbox

Question

Hi all,
We all have seen the functionality of selecting a check box and then click the button and it performs the task(i.e in the hotmail when you select a line/lines by selecting the checkbox for that line and click the delete button those all mails are deleted). we are trying to implement this functionality. I have written the following code for that, but i get the values for the selected box if the box is the first one but if I did not select the first line and select the second line, i get the values for first line as well as for the secondline separated by comma . In other word it concatinates all values. Can I have some pointers?
<INPUT TYPE="CHECKBOX" NAME="selectedBoxes" UNCHECKED value=<%out.println(" \"" + boxValues + "\" ");
And also I don't know how to use the oncheck event for the check box...
Thanks in advance...

Thanks Kan,
But I am littlebit confuse about how does multiple values have been passed. For Example, i have selected 3 check boxes to delete the record. The value for each check box I need is name, event and hours...Each of these record is separated by '*'. I have three sets of values...for three records..
1) Ameeta*overTime*5.00
2) Ameeta*holiday*6.00
3) Ameeta*weekends*8.00
I have total 5 or 6 records for this person(Ameeta) and I want to delete these listed three...some how if I use the following coding it gives me all records before the last checked box...
while(rs1.next())
isEmpty = false;
eventType = rs1.getString("EVENT_TYPE" ) ; ;
eventDate = rs1.getString("EVENT_DATE" ) ;
hours = rs1.getString("HOURS" ) ;
hash += Double.parseDouble(hours) ;
boxValues += eventDate + "*" + hours + "*" shortEvents "#";
userId = rs1.getString("USER_ID" ) ;
// employeeId = rs1.getString("EMP_ID" ) ;
confirmFlg = rs1.getString("CONFIRM_FLAG");
// out.println("\nrecordQuery:\n" + recordQuery ) ;
%>
<tr>
<td colspan=5 width=100>
<INPUT TYPE="CHECKBOX" NAME="selectedBoxes" value=<%out.println(" \"" + boxValues + "\" "); %>>
<td width="150"><%=eventDate%></td>
<td width="150"><%=eventType%></td>
<td width="150"><%=hours%></td>
<td width="150"><%=location%></td>
<td width="150"><%=confirmFlg%></td>
</tr>
**************************************In this code basically I am concatinating so it is obvious that I get every thing before the check box..so I did the following change by adding the line below in the code
while(rs1.next())
boxValues = "";
everything else is same....
but now I get only the last one that is true too because I am asigning it to the null but I don't know how to pass all checked one.........can anybody help me?      
Thanks in advance...
