Titolo: Ripropongo il problema!!! Aiuto!!!

Salve, 
avrei la necessità di far interagire su di un server linux Apache 2.0 e
Tomcat 5.0 tramite il connettore jk2...
Ho provato a configurare tale connettore ma senza successo.
Ho un sito di prova (definito come virtualhost in apache) dove ho inserito
una pagina jsp chiamata index.jsp. Quando la chiamo Apache giustamente la
passa a Tomcat che però carica la sua index.jsp(quella classica di
conferma di avvenuta installazione del Tomcat).
Se poi tento di caricare un'altra pagina jsp mi da errore.
Dove è che sbaglio? Devo fare qualcos'altro?
Grazie mille..
Lupin
P.s. non ho trovato, tra l'altro, una documentazione decente per
quest'argomento....

 Tomcat 5.0 tramite il connettore jk2...
Questa roba l'hai gia' postata ieri, ed abbiamo stabilito che il
problema non sta in Apache o nella configurazione di JK2, ma in
Tomcat che non riconosce il Context. Quindi prima metti a posto
Tomcat, ed assicurati che chiamando direttamente tomcat 
(http:....:8080) si riesca ad accedere all'applicazione, poi il
resto dovrebbe funzionare da se. E non crosspostare su .sys.

Faccio mea culpa..... ho agito cosě perchč ho il fiato sul collo del capo
e non avevo previsto questo problema...mi spiace...
il tomcat risponde bene a http://192.168.1.28:8080....quando invece accedo
a 
http://ssh.minori.it/index.jsp
 il og dice:

Bene, allora cominciano un passo alla volta. Nel tuo
server.xml dovrebbe esserci una voce
<Context path="/quelchee" docBase="/quel/che/e" debug="0" />
Se tu richiami http:....:8080/quelchee devi vedere la tua pagina
index.jsp con tutti gli ammennicoli necessari, finche non e' cosi
e' inutile andare avanti. Se necessario, re-installa Tomcat in modo
da avere un server.xml "pulito".

8080.
         You can also enable an SSL HTTP/1.1 Connector on port 8443 by

         * If your JDK version 1.3 or prior, download and install JSSE

         By default, DNS lookups are enabled when a web application calls
         request.getRemoteHost().  This can have an adverse impact on
         performance, so you can disable it by setting the
         "enableLookups" attribute to "false".  When DNS lookups are
disabled,
         request.getRemoteHost() will return the String version of the
         IP address of the remote client.

the nodes
             mcastPort = the multicast port, has to be the same for all
the nodes
             mcastFrequency = the number of milliseconds in between
sending a "I'm alive" heartbeat
             mcastDropTime = the number a milliseconds before a node is
considered "dead" if no heartbeat is received
             tcpThreadCount = the number of threads to handle incoming
replication requests, optimal would be the same amount of threads as nodes 
             tcpListenAddress = the listen address (bind address) for TCP
cluster request on this host, 
                                in case of multiple ethernet cards.
                                auto means that address becomes
                                InetAddress.getLocalHost().getHostAddress()
             tcpListenPort = the tcp listen port

Selector.select() method in case the OS
                                  has a wakup bug in java.nio. Set to 0
for no timeout
             printToScreen = true means that managers will also print to
std.out
             expireSessionsOnShutdown = true means that 
             useDirtyFlag = true means that we only replicate a session
after setAttribute,removeAttribute has been called.
                            false means to replicate the session after
each request.
                            false means that replication would work for
the following piece of code:
                            <%

                            %>
             replicationMode = can be either 'synchronous' or
'asynchronous'.
                               * Synchronous means that the thread that
executes the request, is also the
                               thread the replicates the data to the other
nodes, and will not return until all
                               nodes have received the information.
                               * Asynchronous means that there is a
specific 'sender' thread for each cluster node,
                               so the request thread will queue the
replication request into a "smart" queue,
                               and then return to the client.
                               The "smart" queue is a queue where when a
session is added to the queue, and the same session
                               already exists in the queue from a previous
request, that session will be replaced
                               in the queue instead of replicating two
requests. This almost never happens, unless there is a 
                               large network delay.

            A session is replicated if and only if all the conditions are
met:
            1. useDirtyFlag is true or setAttribute or removeAttribute has
been called AND
            2. a session exists (has been created)
            3. the request is not trapped by the "filter" attribute
            The filter attribute is to filter out requests that could not

            hence we don't replicate the session after the end of this
request.
            The filter is negative, ie, anything you put in the filter,
you mean to filter out,
            ie, no replication will be done on requests that match one of
the filters.
            The filter attribute is delimited by ;, so you can't escape
out ; even if you wanted to.
            filter=".*\.gif;.*\.js;" means that we will not replicate the
session after requests with the URI
            ending with .gif and .js are intercepted.
