Can select resource content in anonymous block, but not in stored procedure

Question

I know the problem relates to the ACLs but am curious about the following behaviour:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod
PL/SQL Release 10.2.0.1.0 - Production
CORE 10.2.0.1.0 Production
TNS for 32-bit Windows: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
running on Windows XP sp2
Trying to access an existing resource '/home/test/test.dtd'
/home is owned by SYS
/home/test is owned by me
/home/test.test.dtd is owned by me
The following SQL and anonymous block retrieve the content of the resource:
select extract(p.res,'/*').getClobVal()
from resource_view p
where p.any_path = '/home/test/test.dtd'
declare
alldata clob;
begin
select extract(p.res,'/*').getClobVal()
into alldata
from resource_view p
where p.any_path = '/home/test/test.dtd'
dbms_output.put_line(substr(alldata, 1, 255));
end;
BUT when I encapsulate the anonymous block in a stored procedure, I am told that the folder '/home/test/' does not exist.
As said, the problem related to the ACL on the folders, what I cannot understand, and caused me considerable confusion, is why I was unable to get the content from a stored procedure when I was able to do so from an anonymous block.
regards
Richard

Use equals_path(res,'/home/test/test.dtd') = 1OK, OK, but how do you use wildcards (if you want to) since any_path like '/home/test%' works?
Who was the stored procedure owned by. Was it a stand-alone stored procedure or a
method on a package. If it was a method on a package is it AUTHID creator or AUTHID
definer.Everything apart from the '/home' folder is owned by the current user.
The PL/SQL was in a packaged procedure, a stand-alone stored procedure, and an anonymous block. It exhibited the same behaviour in each. All were defined with default AUTHID which is definers rights which is the same as the current user in this case.
