Hello Cayenne people,
First off, thank god for Cayenne. Its made my life a lot better and
Hibernate is but a nightmare now. Thanks.
Ok so my issue. I have a stand-alone app. In this app it uses the ant
api to create a derby database in the users home directory. Some
snippets:
I config ant as :
p.setProperty("dbFile", System.getProperty("user.home")
+ "/portfolioDB");
And then my build.xml says:
<database url="jdbc:derby:${dbFile}"
driverClassName="org.apache.derby.jdbc.EmbeddedDriver" username=""
password="" />
This allows me to inject my ddl into the database on first run and
have the database be localized to the user account across platforms.
I need a way to inject this same ${dbFile} context into the
*Node.driver file so that Cayenne accesses the database I just created
and populated at first run.
Currently mine says:
<url value="jdbc:derby:/portfolioDB;create=true"/>
Which obviously is not dynamic. It would be great if I could set it to
<url value="jdbc:derby:${dbFile};create=true"/>
Is this possible? I am imagining a way to set an environment variable
or some sort of custom config class that sets this. This app is
launched from a webstart so rewriting the config file is not a good
answer for me unless I absolutely have to. That would obviously
require a custom config class of some sort but is a level of
complexity that feels unnecessary.
Thanks, this is a bit into the internals for me and I lose my way quickly.
