                Hi Rawat
                I have a similar problem, because Apache is giving me the same error. I am running JBoss 2.4.2 though. Please let me know whether you got your problem and how you went out solving this:

                My problem goes like this:

                I have been unable to get Budi Kurniawan's application to read anything from the database TassieDB . I am not sure what is wrong. I downloaded the database from the CD. Then since this was an older version of Access, I had to let my Access convert it to the newer form.

                I then configured the Database the way I thought I should in order for it to work. I created a Data Source Name called TassieDB, by following the procedure to create a System DSN on Windows. I selected the Microsoft Access Driver and associated my Database which I named TassieDB1, which I deposited under C:\budibookstore which also contains the package com.brainysoftware.tassie.servlet.ejb

                When I access the SearchServlet page and type in "Computer" in the search box nothing turns up. I wonder what is going on?

                The following errors are spewed out by Apache in this process:

                  hello ilangocal,
                  it is a configuration problem, make sure that you have configured the things apprpriately, send the more details if you have not got the solution yet.

                    Hi Rawat
                    I managed to solve this problem, with the use of the proper jars in their respective places.
                    However I now have a new problem. I keep getting HTTP status code 404 in my pages. I have a package structure as follows: ( i have not used a WAR file)

                    C:\tomcatj\webapps\bookstore\WEB-INF\classes\com\brainysoftware\tassie\ejb

                    here bookstore is my document base. I also have a directory called servlets under tassie called servlets under which I store all the servlet class files.

                    now com\brainysoftware\tassie\ejb
                    and com\brainysoftware\tassie\servlet

                    are the packages that i use in the servlet java files and the EJBs.

                    I suspect that I am unable to load my pages because of a possible error in the Context path setting in the server.xml. My server.xml file is as follows:




                    <!-- Comment these entries out to disable JMX MBeans support -->
                    <!-- You may also configure custom components (e.g. Valves/Realms) by
                    including your own mbean-descriptor file(s), and setting the
                    "descriptors" attribute to point to a ';' seperated list of paths
                    (in the ClassLoader sense) of files to add to the default list.
                    e.g. descriptors="/com/myfirm/mypackage/mbean-descriptor.xml"
                    -->


                    <!-- Global JNDI resources -->

                    <!-- Test entry for demonstration purposes -->

                    <!-- Editable user database that can also be used by
                    UserDatabaseRealm to authenticate users -->

                    pathname
                    conf/tomcat-users.xml



                    <!-- A "Service" is a collection of one or more "Connectors" that share
                    a single "Container" (and therefore the web applications visible
                    within that Container). Normally, that Container is an "Engine",
                    but this is not required.

                    Note: A "Service" is not itself a "Container", so you may not
                    define subcomponents such as "Valves" or "Loggers" at this level.
                    -->
                    <!-- Define the Tomcat Stand-Alone Service -->

                    <!-- A "Connector" represents an endpoint by which requests are received
                    and responses are returned. Each Connector passes requests on to the
                    associated "Container" (normally an Engine) for processing.

                    By default, a non-SSL HTTP/1.1 Connector is established on port 8080.
                    You can also enable an SSL HTTP/1.1 Connector on port 8443 by
                    following the instructions below and uncommenting the second Connector
                    entry. SSL support requires the following steps (see the SSL Config
                    HOWTO in the Tomcat 4.0 documentation bundle for more detailed
                    instructions):
                    * Download and install JSSE 1.0.2 or later, and put the JAR files
                    into "$JAVA_HOME/jre/lib/ext".
                    * Execute:
                    %JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows)
                    $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA (Unix)
                    with a password value of "changeit" for both the certificate and
                    the keystore itself.

                    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.

                    If it is not possible to swap sessions new sessions will
                    be rejected.
                    This avoids thrashing when the site is highly active.
                    minIdleSwap: Sessions must be idle for at least this long
                    (in seconds) before they will be swapped out due to
                    activity.
                    0 means sessions will almost always be swapped out after
                    use - this will be noticeably slow for your users.
                    maxIdleSwap: Sessions will be swapped out if idle for this
                    long (in seconds). If minIdleSwap is higher, then it will
                    override this. This isn't exact: it is checked periodically.
                    -1 means sessions won't be swapped out for this reason,
                    although they may be swapped out for maxActiveSessions.
                    If set to >= 0, guarantees that all sessions found in the
                    Store will be loaded on startup.
                    maxIdleBackup: Sessions will be backed up (saved to the Store,
                    but left in active memory) if idle for this long (in seconds),
                    and all sessions found in the Store will be loaded on startup.
                    If set to -1 sessions will not be backed up, 0 means they
                    should be backed up shortly after being used.

                    To clear sessions from the Store, set maxActiveSessions, maxIdleSwap,
                    and minIdleBackup all to -1, saveOnRestart to false, then restart
                    Catalina.

                    Could you suggest what is going on? I am really stuck and I need the help of experts like yourself.
                    Thanks a lot in advance
