try{
DBResult rst=new DBResult();
}catch(Exception e){}

This means that there is an exception in your program that has not been caught and handled.
Remove the new DBResult() statement from the declared code.
Then add the following statement in the construction method:

try{
rst=new DBResult();
}catch(Exception e){}
or
After writing rst=new DBResult(); into the construction method, declare possible exceptions after the construction method.
Such as:
KhRegist() throws Exception {
    ...
    rst=new DBResult();
    ...
}
