What's this?--Exception creating DataSource: org.hsql.jdbcDriver

Question

How to register the MS-SQL Server2000 DataSource in Tomcat4.04?
Hi friends,
     I only have the MS SQL Server 2000 Database,and prog with jsp and Tomcat.
Since the MS issue their JDBC Driver for SQL Server,I always use "DriverManager"
to get the database connection,
eg:
     Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
     Connection conn = DriverManager.getConnection
("jdbc:microsoft:sqlserver://server1:1433","username","password");
Now I want to use "DataSource" to get connection in my prog,and I know it is necessary to register the DataSouce with JNDI in Tomcat before I can use it.
But how to register and use the SQL Server DataSource in Tomcat4.04? I had tried some times and all failed,tomcat throws a exception like this:"javax.servlet.ServletException: Exception creating DataSource: org.hsql.jdbcDriver"
what is "org.hsql.jdbcDriver"? may be it is tomcat's build in,but how can make my sql server driver work?
     Any Commnet Will Be Appreicate!
----Below is my fail trail when try to config the Tomcat--------------------
Fellow the Tomcat's document,I modify the
"$CATALINA_HOME/conf/server.xml" like this.
<Context path="/MySite" docBase ="MySite" debug = "0" privileged = "true">
<Resource name="jdbc/pubsDb" auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/pubsDb">
<parameter>
          <name>user</name>
          <value>LJS</value>
     </parameter>
     <parameter>
          <name>password</name>
          <value>121212</value>
     </parameter>
<parameter>
          <name>driverClassName</name>
<value>com.microsoft.jdbcx.sqlserver.SQLServerDriver</value>
</parameter>
<parameter>
<name>driverName</name>
<value>jdbc:microsoft:sqlserver://localhost:1433/pubs</value>
</parameter>
</ResourceParams>     
</Context>
PS: the MSSQL Sever2000 has installed and had a user named "LJS" which password is 121212
and default database is "pubs".
Then,I modified the $CATALINA_HOME/webapps/MySite/WEB-INF/web.xml like this
     <resource-ref>
          <description>
               Resource reference to a factory for java.sql.Connection
               instances that may be used for talking to a particular
               database that is configured in the server.xml file.
          </description>
          <res-ref-name>
               jdbc/pubsDB
          </res-ref-name>
          <res-type>
               javax.sql.DataSource
          </res-type>
          <res-auth>
               Container
          </res-auth>
     </resource-ref>     
finally I code a DB.jsp like this
<%@ page content="text/html"%>
<%@ page import="java.sql.*,javax.sql.*,java.naming.*"%>
<%
     Context ctx = new InitialContext();
     DataSource ds = (DataSource)(new InitialContext().lookup("java:comp/env/jdbc/pubsDB"));
%>
     after all done, I launch the Tomcat 4.0 and type "http://localhost:8080/MySite/DS.jsp" in
my browser.
     then Tomcat throw exception like this:

Answer 1

Hi,
don't know if you've already found a solution to this problem. Anyway, I had the same problem and the cause turned out to be a non-valid server.xml file.
Here is my (working) server.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Example Server Configuration File --><!-- Note that component elements are nested corresponding to their
parent-child relationships with each other --><!-- A "Server" is a singleton element that represents the entire JVM,
which may contain one or more "Service" instances. The Server
listens for a shutdown command on the indicated port.
Note: A "Server" is not itself a "Container", so you may not
define subcomponents such as "Valves" or "Loggers" at this level.
--><Server debug="0" name="TestServer" port="8005" shutdown="SHUTDOWN">
<!-- 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 -->
<Service name="Tomcat-Standalone">
<!-- 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:
* Download and install JSSE 1.0.2 or later, and put the JAR files
into "$JAVA_HOME/jre/lib/ext".
* Edit "$JAVA_HOME/jre/lib/security/java.security" and add
security.provider.2=com.sun.net.ssl.internal.ssl.Provider
* Execute: keytool -genkey -alias tomcat -keyalg RSA
with a password value of "changeit".
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.
-->
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector acceptCount="10" className="org.apache.catalina.connector.http.HttpConnector" connectionTimeout="60000" debug="0" enableLookups="true" maxProcessors="75" minProcessors="5" port="8080" redirectPort="8443"/>

to -1 -->

<!-- An Engine represents the entry point (within Catalina) that processes
every request. The Engine implementation for Tomcat stand alone
analyzes the HTTP headers included with the request, and passes them
on to the appropriate Host (virtual host). -->
<!-- Define the top level container in our container hierarchy -->
<Engine debug="0" defaultHost="localhost" name="Standalone">
<!-- 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

element inside the corresponding <Host> or <Context> 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
