process: invoke java.lang.NoSuchMethodError
I am using Tomcat 4.0.4, Apache 1.3.12, JDK 1.3.1 on Windows 2000 Server.
When trying to run a jsp file I get the error:

The short answer is... No :-)
A longer answer is that the Connection Pool still provides objects of
type javax.sql.DataSource. This is good, because it means that our
servlet code doesn't change if we switch between no pooling, and pooling
of connections.

I asked this one time in this list but no reply... let's try again.
When we use the pool configuration indicated in tomcat docs, we use
the javax.sql.DataSource interface to get the java.sql.Connection
instances.
To have connection pooling we shouldn't use ConnectionPoolDataSource?

Yes, I have it in my server.xml.
I actually fixed the problem by changing my jdbc url
from
<parameter>
<name>driverName</name>
<value>jdbc:postgresql://postgresql1.blah.com:5432/</value>
</parameter>
TO
<parameter>
<name>driverName</name>
<value>jdbc:postgresql://postgresql1.blah.com:5432/dbname</value>
</parameter>
to include the name of the database at the end of the URL.

First quick look says me that you need one extra line before
<ResourceParams>....</ResourceParams> entry
It should be something like
<Resource name="jdbc/IFDB" auth="Container"
type="javax.sql.DataSource" description="blah blah blah"/>
Do you have it and miss it in you e-mail or you don't have it at all?

postgresql jndi jdbc getConnection() problem
Posted by adam kramer <ad...@monkey.org>.
I saw one other post on the archives about this but it has no resolution.
I have set up Tomcat 4.0.4 to use the jndi resource factory to use pgsql
jdbc connection "pooling" (fake pooling).
Whenever I call the second
line of this code:
Context ctx = (Context) new InitialContext().lookup("java:comp/env");
conn = ((DataSource) ctx.lookup("jdbc/IFDB")).getConnection();
I get a "Something unusual has occured to cause the driver to fail. Please
report this exception: Exception: java.lang.NullPointerException Stack
Trace: java.lang.NullPointerException at
org.postgresql.Connection.openConnection(Connection.java:155)"
error.
My server.xml resource looks like this within the context tag:
<ResourceParams name="jdbc/IFDB">
<parameter>
<name>user</name>
<value>kenjackson</value>
</parameter>
<parameter>
<name>password</name>
<value>29gzy8</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>org.postgresql.Driver</value>
</parameter>
<parameter>
<name>driverName</name>
<value>jdbc:postgresql://postgresql1.eapps.com:5432/</value>
</parameter>
</ResourceParams>
NOTE: I have changed the user parameter to name "username" but that
doesn't help and the tyrex api asks for "user" so I'm assuming that's
right.
and my webapp web.xml:
<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/IFDB
</res-ref-name>
<res-type>
javax.sql.DataSource
</res-type>
<res-auth>
Container
</res-auth>
</resource-ref>
Has anyone else run into a similar problem. From what I have seen on the
list the Tyrex api is a problem, but I'm currently stuck with it.
thanks,
Adam Kramer
