Hi,
I just tried to run my app with Merlin CVS, normally I'm running version
3.2.5.
It seems that it ignores the path I specify with the -library CLI option
(though it does show up as merlin.anchor in the environment listing),
and instead tries to use the current working directory.
After some digging around in the merlin code I came up with this:
- the "-library" option gets transfered to
KernelCriteria.getAnchorDirectory(), which in the API is described as
the directory "to be used when resolving library declarations in
classload specifications." Further this path gets set as an attribute
called "urn:composition:anchor" in the Context object supplied to the
SystemContextFactory. This context key doesn't seem to be used anywhere.
- The directory which however seems to be used is
SystemContext.getBaseDirectory(), described in the API as "the base
directory from which relative references should be resolved" (doesn't
say 'library' references per se, but from inspecting the usages of that
method I guess that's the purpose). However, the value used for that is
InitialContext.getInitialWorkingDirectory().
I've attached a patch with a possible solution. It simply sets the base
directory explicitely on the SystemContextFactory, as is done for the
other (home/temp) directories.
If I got it right that base and anchor are the same directories, maybe
they would better share the same name?
