data-source for default derby maildb is configured with a relative path

Data source is configured with a relative path in config.xml:

<dburl>jdbc:derby:../apps/james/var/derbydb;create=true</dburl>

The path is relative to the current directory when starting james. Calling run from the bin folder is allright. Calling it from James root directory bin\run.bat causes the db to be created in the uplevel directory.

Possible solutions:

• add a "cd PHOENIX_HOME" in start scripts
• evaluate the PHOENIX_HOME enviroment variable in James
