Hi there,
There are a few things at play here (and I think there's also a Cayenne bug in
3.1 that we need to fix )... So when you do this:
ServerRuntime econfigContext = new
ServerRuntime("conf/cayenne-UntitledDomain.xml")
The location String ("conf/cayenne-UntitledDomain.xml" in your case) is
internally resolved to a "resource" using
org.apache.cayenne.resource.ResourceLocator service. Its default implementation
is ClassLoaderResourceLocator. So the location is interpreted as a Java
resource accessible somewhere on CLASSPATH.
If you decide to move your XML file out of CLASSPATH location and to somewhere
outside the application, you will need to change this strategy from CLASSPATH
resource lookup to filesystem lookup.
org.apache.cayenne.resource.FilesystemResourceLocator supports finding
resources on the filesystem, as the name suggests.
So you will need to create a custom module that configure the default
ResourceLocator to be FilesystemResourceLocator. E.g.:
Module myModule = new Module() {
void configure(Binder binder) {
binder.bind(ResourceLocator.class).toInstance(new
FilesystemResourceLocator(new File("c:\"));
}
}
ServerRuntime econfigContext = new
ServerRuntime("conf/cayenne-UntitledDomain.xml", myModule);
Now Cayenne will look for all locations relative to "c:\". But make sure all
you .map.xml files are also in the same location as the main XML, as they will
be resolved via relative paths.
Now unfortunately there's a glitch with rebinding ResourceLocator in this way
(or at least I think there is, I haven't tried a test to reproduce it) - in
addition to loading user XML files, the default ResourceLocator is also used to
load DbAdapter types.xml file (an internal Cayenne thing that users rarely have
to care about). I will log this bug in Jira to investigate further. As a
temporary workaround, you may grab types.xml from Cayenne sources and put it in
C:\ (or a subfolder of C:\ that you designate as a FilesystemResourceLocator
"root").
Hope this helps.
