Please help i am having this error for the past 3 day, but i wasn't
able rectify this error, pls help me,
WEB-INF/
web.xml
classes/
UserDetails.class

Production code belongs in named packages. This directory structure
indicates that the UserDetails is in the default package (no package
statement at the top). Package your code and the problem will most likely
go away.

There's a part of the JLS that says you cannot import a class in the default
package (no package statement) into a class in a named package. I think
that's what you're running into.

It would have been more useful to see the error message than everything you
posted.

Please help i am having this error for the past 3 day, but i wasn't

So what's the error (EXACT text please)? Also include your web.xml.

 

[Michael Scovetta]

I've had similar problems, I fixed it by putting the class into a
package and importing it from JSP. The app server should output the
compilation error. You can also try compiling the JSP directly with
JSPC/Jasper. It probably can't find UserDetails.

Oh, and please remember to .close() your Connections,
[Prepared]Statements, and Recordsets-- letting the GC do it is not a
good idea. I use a simple:

Connection conn = null;
PreparedStatement pstmt = null;
ResultSet rs = null;
try {
conn = DBFactory.getConnection(); // my own factory method
pstmt = conn.prepareStatement( /* Query */ );
rs = pstmt.executeQuery();

while (rs.next()) {
// whatever
}
} catch (SQLException ex) {
// Log the error
} finally {
DBFactory.close(conn, pstmt, rs);
}

Where DBFactory.close() is the big nasty:
/**
* Closes connections to Connection, PreparedStatement, and
ResultSet objects.
* @param conn Connection object, null is alright
* @param pstmt PreparedStatement object, null is alright
* @param rs ResultSet object, null is alright
*/
public static void close( Connection conn,
PreparedStatement pstmt,
ResultSet rs ) {
if (rs != null)
try {
rs.close();
} catch (Exception e) {
}
if (pstmt != null)
try {
pstmt.close();
} catch (Exception e) {
}
if (conn != null)
try {
conn.close();
} catch (Exception e) {
}
}
