JSP- getting array data into jsp from java

Question

I have to display data fetched from DB to JSP. I am using spring MVC. I have stored data in List in java. Now i need to access this list in JSP and display it in tabular form.

Answer 1

You can add your data in session and access it in table.jsp.

Once you get data on JSP you can easily render as you want using html + jsp combination.

Hope this helps.

Answer 2

List<List<?>> data = new ArrayList<List<?>>();
int col = -1;
List<?> row;
while(rs.next())
{
  if (col != rs.getInt(1))
  {
    col = rs.getInt(1);
    row = new ArrayList<?>();
    data.add(row);
  }
  row.add(rs.getObject(3));
}
getRequest().setAttribute(data);

Answer 3

• Process it on servlet and store it in 2D array of String or List<List<String>>

• Set it as attribute to request, forward request to jsp.

• on jsp use JSTL to represent data. using <c:forEach>
