I posted an example how to setup a datasource for oracle database (but it
was using tomcat 4.1.9).
Btw, try to upgrade to tomcat 4.1.9, it has some bug fixes regarding JNDI
and datasource.

Hi all!
I have 2 web applications that runs in my Tomcat 4.1.8 server.
Every thing works fine if i run only one of the two applications.
If i run one application and then the other i get this exception
org.apache.jasper.JasperException: Native Library
C:\oracle\ora81\bin\ocijdbc8.dll already loaded in another classloader
I´m trying to create a data source to solve this problem,
i´ve done all i found in tomcat-docs:
1. Create the data source
<Resource name="jdbc/myoracle" auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/myoracle">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:oracle:oci8:[EMAIL PROTECTED]:1521:mysid</value>
</parameter>
<parameter>
<name>username</name>
<value>scott</value>
</parameter>
<parameter>
<name>password</name>
<value>tiger</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>20</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>10</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>-1</value>
</parameter>
</ResourceParams>
2. Configure web.xml (i added this line)
<resource-ref>
<description>Oracle Datasource example</description>
<res-ref-name>jdbc/myoracle</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
3. I have a bean that creates a connection like this
Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("jdbc/myoracle");
Connection conn = ds.getConnection();
The problem is that the connection whit my oracle data base
cannot be creates because i get this execption:
java.sql.SQLException: Cannot load JDBC driver class 'null'
I don´t know if the problem is with the bean or with the server.xml or with
both
How can i check if the Data source is working fine since i found nothing
in the log files.
Thanks in advance
