ilangocal May 19, 2005 4:27 AM (in response to rawat_tejinder)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:

rawat_tejinder May 26, 2005 6:53 AM (in response to rawat_tejinder)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. -
6. new problem
ilangocal May 26, 2005 8:29 AM (in response to rawat_tejinder)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 -->

UserDatabaseRealm to authenticate users -->

<!-- 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.

<!-- An Engine represents the entry point (within Catalina) that processes

analyzes the HTTP headers included with the request, and passes them
on to the appropriate Host (virtual host). -->
<!-- You should set jvmRoute to support load-balancing via JK/JK2 ie :

<!-- Define the top level container in our container hierarchy -->
<!-- The request dumper valve dumps useful debugging information about
the request headers and cookies that were received, and the response
headers and cookies that were sent, for all requests received by

particular virtual host, or a particular application, nest this
element inside the corresponding or entry instead.
For a similar mechanism that is portable to all Servlet 2.3
containers, check out the "RequestDumperFilter" Filter in the
example application (the source for this filter may be found in
"$CATALINA_HOME/webapps/examples/WEB-INF/classes/filters").
Request dumping is disabled by default. Uncomment the following
element to enable it. -->

<!-- PersistentManager: Uncomment the section below to test Persistent
Sessions.
saveOnRestart: If true, all active sessions will be saved
to the Store when Catalina is shutdown, regardless of
other settings. All Sessions found in the Store will be
loaded on startup. Sessions past their expiration are
ignored in both cases.
maxActiveSessions: If 0 or greater, having too many active
sessions will result in some being swapped out. minIdleSwap
limits this. -1 or 0 means unlimited sessions are allowed.
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.
