Apologies if this is a slightly “lower level” problem than normal but I
think I am going slowly mad.
I have just started working with cocoon 2 and am having some problems
getting this to connect to mySQL. I have followed the tutorials to the
letter and am getting an
Exception in ServerPagesGenerator.generate()
Java.Lang.NullPointerException
My mySQL database appears to be up and running, Cocoon will quite
happily do it's think with xml, xsl and the basic "hello world" xsp
files. This only occurs when I try and access a db with ESQL.
(I'm using mySQL 3.23.52, Cocoon 2.03, Tomcat 4.1, JDK 1.3.1,
mySQL-connector-java-2.0.14, all running on win xp)
My cocoon.xconf contains the following datasources entry
<datasources>
<jdbc logger="core.datasources.autorevs_store"
name="autorevs_store">
<pool-controller min="5" max="10">
<keepalive>SELECT 1;</keepalive>
</pool-controller>
<driver>org.gjt.mm.mysql.Driver</driver>
<dburl>jdbc:mysql://localhost:3306/autorevs</dburl>
<user>web</user>
<password>webpass</password>
</jdbc>
</datasources>
And a fuller stack trace is as follows:
