Throw exception error everywhere in JSP!

Question

I've wrote a JSP to access SQL Server database in J2SE sucessfully, but when
I try that on a different server using Java 1.1 I get the same type of
errors complaining about
"the method " blah blah blah" can throw the checked exception
"java/lang/ClassNotFoundException", but its invocation is neither enclosed
in a try statement that can catch that exception nor in the body of a method
or constructor that "throws" that exception."
this is another sample of my errors
31. Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
<------------------------------------------->
*** Error: The method "java.lang.Class forName(java.lang.String $1);" can
throw the checked exception "java/lang/ClassNotFoundException", but its
invocation is neither enclosed in a try statement that can catch that
exception nor in the body of a method or constructor that "throws" that
exception.
33. Connection con=DriverManager.getConnection(url, "ema", "ema");
<-------------------------------------------->
*** Error: The method "java.sql.Connection getConnection(java.lang.String
$1, java.lang.String $2, java.lang.String $3);" can throw the checked
exception "java/sql/SQLException", but its invocation is neither enclosed in
a try statement that can catch that exception nor in the body of a method or
constructor that "throws" that exception.
Am I missing some libraries or calling the method incorrectly because of the
version of Java was older?
Here I also attached my code
<%
//connection and query
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url="jdbc:odbc:DB";
Connection con=DriverManager.getConnection(url, "sa", "password");
PreparedStatement query = con.prepareStatement("select Quarter, Month,
WeekDay, statusCode, Responded, CNT from REQUEST",
ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
ResultSet rs = query.executeQuery();
rs.last();
int numrows = rs.getRow();
rs.beforeFirst();
%>
Thanks in advanced
