Hello <%= (request.getRemoteUser() != null? ", " + request.getRemoteUser() : "") %> ! I am Connection Caching JSP.


Session Level Connection Caching.

<% try { ods.setURL(connStr); ods.setUser("scott"); ods.setPassword("tiger"); Connection conn = ods.getConnection (); Statement stmt = conn.createStatement (); ResultSet rset = stmt.executeQuery ("SELECT ename, sal " + "FROM scott.emp ORDER BY ename"); if (rset.next()) { %> <% while (rset.next()) { %> <% } %>
Employee Name Salary
<%= rset.getString(1) %> $<%= rset.getDouble(2) %>
<%= rset.getString(1) %> $<%= rset.getDouble(2) %>
<% } else { %>

Sorry, the query returned no rows!

<% } rset.close(); stmt.close(); conn.close(); // Put the Connection Back into the Pool } catch (SQLException e) { out.println("

" + "There was an error doing the query:"); out.println ("

" + e + "
\n

"); } %>
