Mysql experts - major problem with my mythtv database

Question

I'm running mythtv which uses mysql to store its program data and I'm in over my head.  Basically, when I updated from mythtv 0.21-fixes to 0.22, the database schema needed to get updated as well.  I ran some errors that I don't understand, nor can I find anything meaningful via googling around.
Here is a clip of my /var/log/mythtv/mythbackend.log

I have no idea what these errors are nor how to resolve them.  Any advise is greatly appreciated.

Hello,
First of all:
your validate method signature is:
public ResultSet validateUser( String u, String p) throws SQLException, BUT, String u and String p are never used in the query statement, instead of SELECT ... FROM tblUsers WHERE loginName=? AND password=? and then update query parameters with u and p, you retrieve ALL users to front-end, which is a bad practice, what would web server load be if you have 10000 users on on that DB for that particular application? It's a permormance killer.
Second:
while(rs.next()){
String u1 = rs.getString("name");
String p1 = rs.getString("Password");
if (u1.equals(username) && (p1.equalsI(password))){
break;
%>
<jsp:forward page="err.html" />
<%}
out.println("You Are a Valid User");
because the forward is inside the loop, if the first row in result set doesn't match inputed parameters, loop is not going to be broken and the next statement inside the loop is the forward.
Hope this help
