Solaris + Tomcat Installation Problem

I've been following the instructions on http://confluence.jetbrains.net/display/TCD5/Installing+and+Configuring+the+TeamCity+Server and setting up the Generic J2EE deploy to Tomcat 6 running on Solaris.

I've modified my catalina.sh to include the following line

JAVA_OPTS="-Dlog4j.configuration=file:../conf/teamcity-server-log4j.xml -Dteamcity_logs=../logs/ -Dteamcity.data.path=/opt/teamcity"

I included useBodyEncodingForURI="true"  in the connector tag of server.xml

The TeamCity application appears to be correctly installed according to the Tomcat Service Manager and tomcat is the owner of the data path directory as follows:

total 8
drwsrwsrwx   4 tomcat   tomcat       512 Jul 22 20:23 ./
drwxr-xr-x  15 root     sys          512 Jul 22 20:22 ../
drwxr-sr-x   2 tomcat   tomcat       512 Jul 22 20:23 config/
drwxr-sr-x   5 tomcat   tomcat       512 Jul 22 20:23 system/

However, when I try accessing the application I get the following error (full stack trace attached).

Error creating bean with name 'jspPrecompiler' defined in ServletContext resource [/WEB-INF/buildServerSpringWeb.xml]: Initialization of bean failed; nested exception is java.lang.NullPointerException
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jspPrecompiler' defined in ServletContext resource [/WEB-INF/buildServerSpringWeb.xml]: Initialization of bean failed; nested exception is java.lang.NullPointerException

Any ideas anyone?

Thanks.
