Exception running DAS company-webapp sample
I'm testing the DAS company-webapp sample. I followed the steps in
readme.htm, copied derby JAR to lib, edited server.xml and I'm getting
the following exception when I start Tomcat:

I'm trying in my linux env, just to check if it's some linux specific
issued, but in paralel, could you please try to move the resource
declaration :
<!-- Global Datasource for Derby dastest database -->
<Resource name="jdbc/dastest"
type="javax.sql.DataSource" auth="Container"
description="Derby database for DAS Company sample"
maxActive="100" maxIdle="30" maxWait="10000"
username="" password=""
driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
url="jdbc:derby:/tmp/dastest;create=true"/>
Together with other resources, inside the global JNDI Resources element
<!-- Global JNDI resources
Documentation at /docs/jndi-resources-howto.html
-->
<GlobalNamingResources>
....
Please let me know if this makes any difference.
