Ok...
1) I don't see a tomcat version, could you post that?
2) Are you sure the tomcat version on the production environment the
same as your dev system?
3) This is probably not causing the immediate problem, but <res-type>
... </res-type> in your web.xml should be javax.sql.Datasource, not
oracle.jdbc.pool.OracleDataSource.

Seems like such a generic error would have a root cause. Was there
anything more to the stack trace?

Hi,
I am trying to connect to an oracle database but cant seem to get the jdbc
connection to work. I am developing the application on a Windows desktop
and
transferring it onto a Unix box.
When i test it on the Windows environmnet it does manage to connect but if
i
test it on unix then i get an error. My gut feeling is that the
installation
on the unix environment is missing a library but i cant figure out what it
is.
Here is how i am trying to get the jndi connection.
[code]
String fullname;
if (jndiPrefix != null && jndiPrefix.length() > 0)
fullname = jndiPrefix + datasource;
else
fullname = datasource;
// JNDI
Context ctx = null;
DataSource ds = null;
Connection conn = null;
try
{
ctx = new InitialContext();
Context envContext = (Context)ctx.lookup("java:/comp/env");
if (ctx != null)
{
ds = (DataSource)envContext.lookup(fullname);
if (ds != null)
{
conn = ds.getConnection();
}
}
}
[/code]
And here is the Configuration.
Context.xml (User and password modified)
[code]
<Resource name="jdbc/theDb" auth="Container"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@localhost:1521:webdev"
username="webuser" password="webuser" maxActive="20"
maxIdle="10"
maxWait="-1"/>
[/code]
web.xml
[code]
<resource-ref>
<description>Oracle Datasource</description>
<res-ref-name>jdbc/theDb</res-ref-name>
<res-type>oracle.jdbc.pool.OracleDataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
[/code]
And here is the stack trace of the error

What i dont understand is why it works on the installation on the windows
environment but not in the Unix environment. I check all the libraries and
everything under common/lib is the same for both environments.
Thanks
