I did it by pre-generating html in callProcedure class. Save it in to String and passed it in a sendEmail method.
String text=
"<table width='100%' border='1' align='center'>"
+ "<tr align='center'>"
+ "<td><b>Product Name <b></td>"
+ "<td><b>Count<b></td>"
+ "</tr>";
for (Map.Entry entry : ProductwiseCount.entrySet()) {
System.out.println(entry.getKey() + " :" + entry.getValue());
text=text+"<tr align='center'>"+"<td>" + entry.getValue() + "</td>"
+ "<td>" + entry.getKey() + "</td>"+"</tr>";
}
sendMail.sendMail(host, port, to, from,text);
