Bad version number in .class file during deploy

[paoletto]

Hi! Im new to roller!

I tried to deploy it today but i got a strange exception as below.

What i did is:
- used my tomcat5.5 running installation (which has some web app on)

- created a "roller" db on my postgres8.2 server and a roller user and
granted ALL to USER roller for db roller

- configured the roller-custom.properties in tomcat5.5/common/classes/
as follow:

# cat ../common/classes/roller-custom.properties
installation.type=auto
database.configurationType=jdbc
database.jdbc.driverClass=org.postgresql.Driver
database.jdbc.connectionURL=jdbc:postgresql://localhost:5432/roller
database.jdbc.username=roller
database.jdbc.password=xxxxxxxxx
mail.configurationType=properties
mail.hostname=localhost

- put postgresql jdbc drivers along with mail.jar and activation.jar
in common/lib/

- packed the webapp/roller directory into roller.war and copied into
tomcat5.5/webapps


the log is like:

Make sure you are using Sun Java SDK 1.5.
