Hello Ted-
I'm a newb w/ Hibernate and not Struts. With some difficulties but
i've managed to install struts-hibernate example on Tomcat-4.1.24 and
Firebird-1.0. And have a lot of questions.
What should this example show? I mean how to play with this example? I
did not find any help, only readme about how to install this example. Well,
I've installed it. What next? I see a text entry with Submit button and 3
links at http://localhost/eg1/Welcome.do. What should I enter? And what
shall I expect after pressing submit? Really lost.
Moreover, when i press submit butoom (whatever i enter) the result is
always error. Why? I see message - Could not execute query. And find it:
public static String HQL_FIND_USER = "FROM user IN class eg.User WHERE
user.userName = ?";
Is it really a problem in this query? Its incompleteness? Tomcat
complaints on dot. Or is this a firebird sql specific problem?
Really appreciate your comments,
Sergei.
