What about
<jsp:useBean id="mes" type="mesto.Mesto" scope="session"/>
instead of
<jsp:useBean id="mes" class="mesto.Mesto" scope="page"/>
PS
Sorry for my previous post - I didn't read carefully your question...

: Hello Werner,
: thank you for your advice, but It didn't helped.
:
: I did now these thinks:
:
: 1) I created new directory
: /usr/adissys/pok_JSP/SB/vzor/WEB-INF/classes/mesto;
: 2) I moved Mesto.java from /usr/adissys/pok_JSP/SB/vzor/WEB-INF/classes
: directory
: to /usr/adissys/pok_JSP/SB/vzor/WEB-INF/classes/mesto directory;
: 3) I added to Mesto.java one line:
: package mesto;
: 4) I compiled Mesto.java at that new directory: OK (was created file
: Mesto.class);
: 5) I replaced at mesto.jsp the old line
: <jsp:useBean id="mes" class="Mesto" scope="page"/>
: to the new line
: <jsp:useBean id="mes" class="mesto.Mesto" scope="page"/>;
: 6) I restarted Tomcat;
: 7) I called mesto.jsp, but the same error persits!
:
: Can you advise why?
:
: Thanks

: Hello Mirek,
: I had the same problem about a week ago.
: You can search the archives for the message entitled :
:
: " JSP : Can not retrieve Object stored from servlet into session"
: The solution as explained by Craig Mc Clanahan is :
: <QUOTE>
: If you want to use a Java class in a <jsp:useBean> action, it *should* be
: in
: a package.
:
: The reason for this has to do with the way that Java compilers look at
: classnames with no packages. They assume that the class is in the same
: package as the calling class itself (in this case, the servlet class that
: is
: generated from your JSP page). However, different servlet containers
: generate these servlets into different packages. In order to be portable,
: you must put your own beans in packages to make this unambiguous.
:
: The values you specify for the "type" or "class" attributes of the
: <jsp:useBean> action must be fully qualified class names (i.e. they must
: include the package prefixes).
: </QUOTE>
:
: That solves your problem !
