Hi Experts,
           I have the attached table on my jsp page. As you can see, this is not a pretty table. What I want to achieve is that:
     * Right now I am displaying an equation like 10/100=10%.
     What I want is: Just to display 10% in every cell but when a user rolls his mouse over the value, it should display the calculation 10/100=10% in a small pop up like display.

      Right now I have no clue how to do this. please help me out.

I suppose, the simplest and proven way to achieve the desired behavior is to do the following:
(See the modified line in the attached code snippet)

1. place information you want to display on mouseOver into a value of 'title' attribute of a <TD> element.
2. reduce data amount within <TD></TD> as you've mentioned above.

At run time a value of 'title' attribute will be displayed as "Tooltip" in most browsers.
If it you need more styling/displaying options then you will have to extend this solution by means of JavaScript/CSS.

3. Write JS/CSS code that meet your need and embed it into the page source at a proper place.
4. For each <TD> element generate/add:
   a)  a unique 'id' attribute.
   b) onmouseover="javascript:{funcName}('{ID}')" AND onmouseout="javascript:{funcName}('{ID}')" entries
   {funcName} is the name of your JS mouse event handler (see 3.)
   {ID} is the value of id attribute of that particular <TD> element.

I wish you a lot of success,

<TD align="center" title="<%= totalMetrics==0 ? "NA" : rs1.getInt(5)+"/"+rs1.getInt(6)+"="+rs1.getFloat(7)+"%" %>"><%= totalMetrics==0 ? "NA" : rs1.getFloat(7)+"%" %></TD>

Code and snapshot to be replaced in the question:

<table border="1" cellspacing="1" bgcolor="#FFFFFF" style="font-size:0.9em" width="500">
                <th align="center"><b>App</b></th>
                        Calendar cal = Calendar.getInstance();
                        SimpleDateFormat sdf = new SimpleDateFormat("MMM");
                        cal.set(Calendar.MONTH, Calendar.JULY);
                        for (int i = 0; i < 12; i++) {
                                  java.util.Date month = cal.getTime();
                <TH align="center"><%=sdf.format(month)%></TH>
                        cal.roll(Calendar.MONTH, 1);
                Connection conn = null;
                conn = db.getConnection();
                String sql = "";
                PreparedStatement pstmt, subpstmt = null;
                ResultSet rs, rs1 = null;
                sql = "Select DISTINCT App from SAMPLE_TABLE";
                pstmt = conn.prepareStatement(sql);
                rs = pstmt.executeQuery();
                while ( {
                                String subquery = "Select * from( Select * from SAMPLE_TABLE2 WHERE APPL IN ('"
                                + rs.getString(1)
                                + "') ORDER BY YEAR , DECODE(UPPER(MONTH), 'JAN', 7, 'FEB', 8, 'MAR', 9, 'APR', 10, 'MAY', 11, 'JUN', 12, 'JUL', 1, 'AUG', 2, 'SEP', 3, 'OCT', 4, 'NOV', 5, 'DEC', 6) ) WHERE ROWNUM<=12 and ASP='xyz'";
                                subpstmt = conn.prepareStatement(subquery);
                                rs1 = subpstmt.executeQuery();
                                while ( {
                        int totalMetrics = rs1.getInt(6);
                <TD align="center"><%= totalMetrics==0 ? "NA" :  (rs1.getInt(5)+"/"+rs1.getInt(6)+"="+rs1.getFloat(7)+"%") %></TD>
