LinuxQuestions.org - Deploy Apache Continuum on Tomcat6

Hi,

I have ubuntu 10.04LTS server.
Open jdk and tomcat6 installed from synaptic package manager.
I run different war files on tomcat6.
I downloaded apache-continuum-1.3.7.war.
I followed the instructions on apache continuum web site.
http://continuum.apache.org/docs/1.3...on/tomcat.html

1)I wrote /etc/init.d/tomcat6 this commands:
CONTINUUM_HOME=/var/lib/tomcat6
JAVA_OPTS="-Dappserver.home=$CONTINUUM_HOME -Dappserver.base=$CONTINUUM_HOME"
2)I put jar files to /var/lib/tomcat6/webapps/apache-continuum-1.3.7/WEB-INF/lib and /var/lib/tomcat6/common/lib also
3)I installed postfix as a smtp server
4)I created context.xml file /var/lib/tomcat6/webapps/apache-continuum-1.3.7/META-INF/context.xml

<Context path="/apache-continuum-1.3.7"
docBase="/var/lib/tomcat6/webapps/apache-continuum-1.3.7.war">

<Resource name="jdbc/users"
auth="Container"
type="javax.sql.DataSource"
username="sa"
password=""
driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
url="jdbc:derby:database/users;create=true" />

<Resource name="jdbc/continuum"
auth="Container"
type="javax.sql.DataSource"
username="sa"
password=""
driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
url="jdbc:derby:database/continuum;create=true" />

<Resource name="mail/Session"
auth="Container"
type="javax.mail.Session"
mail.smtp.host="localhost"/>
</Context>

5) But I can't run continuum. I have these error in my log file. (catalina.out)
It creates continuum.log also.
