The following was posted a couple of days ago, and the bug marked as RESOLVED
and FIXED. However, there was also the comment included below which seems to
indicate that the resolution was *not* to place JDBC drivers in the
common/lib directory, but rather add the JDBC jar to the classpath manually.
This is rather confusing. This is a different behavior to Tomcat 4.0.4 (which
I'm using now), and is undocuented. Ideally it should be fixed so that the
common/lib directory is used, as is the case with older versions.

I have been dealing with the same problem for a few days and managed to find
one solution for it.
I'm using Tomcat 4.1.27 and Sybase database running on Win2K(also tried in XP
and same assembly worked fine).
In my server.xml I have Context under <host> as follows:
<Context path="/MyApp"
docBase="MyApp"
debug="5"
reloadable="true"
crossContext="true">
<Resource name="jdbc/dbref"
auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/dbref">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>10</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>2</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>10000</value>
</parameter>
<parameter>
<name>username</name>
<value>report</value>
</parameter>
<parameter>
<name>password</name>
<value>report</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>com.sybase.jdbc2.jdbc.SybConnectionPoolDataSource</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:sybase:Tds:xxx:5000/dbname</value>
</parameter>
<parameter>
<name>removeAbandoned</name>
<value>true</value>
</parameter>
<parameter>
<name>removeAbandonedTimeout</name>
<value>60</value>
</parameter>
</ResourceParams>
</Context>
In my web.xml I have:
<resource-ref>
<description>Sybase Datasource</description>
<res-ref-name>jdbc/dbref</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
,and in Java:
Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup("java:/comp/env");
dataSource = (javax.sql.DataSource)envContext.lookup(dataSourceName);
Connection con = dataSource.getConnection();
I installed Java 2 Runtime Environment 1.4.2_01 and modified system variables:
JAVA_HOME = "j2re 1.4.2_01 install dir"
CLASSPATH = "3rd party database driver jar directory"
CATALINA_HOME = "Tomcat install dir"
Although Jakarta Tomcat 4.1 "JNDI Datasource HOW-TO" docs adviced not to
install 3rd party database drivers anywhere else than in
$CATALINA_HOME/common/lib I tried adding jar into CLASSPATH and it worked
fine.
Make sure you have jre installed and JAVA_HOME set into that dir and it should
work fine.
