Re: OJB and Oracle 9ias

[Wayne Kidd]

The real question is where do you put ojb.properties.  Nothing else 
really matters.  Once the system can find that, it can be told to find 
anything.  It must be in the direct classpath of OC4J.  If you put it in 
a package structure (lower than classes), it will not be found because 
the property loader needs the fully qualified "classname" of the 
properties file.  This is a strange sounding term, but it means that 
when reading properties from the classpath, the loader of properties 
works a lot like a class loader.  What it does is take the file name 
(first part).  and uses it like a class name (case is important).  It 
assumes that the filetype (in MS terms) is .properties instead of 
.class.  It treats the folder structure like a package name.  You could 
set a startup parameter to change the "fully qualified "classname"" to 
something else.  But, if you want to do it vanilla, then you must 
arrange that the ojb.properties file does not have a package (is not in 
a folder structure).

I definitely appreciate that bit of information.  However, I don't think
that OJB.properties file is found, so whatever I put in there is moot at
this point.  Do I need to setup the system property for OJB.properties
too?
Thanks,

I use OJB with 9ias.   Here are the special things that I do 
to make it 
happen.

1).  I place ojb.properties into WEB-INF/classes
2).  I also place xxx.xml (repository.xml) into the same 
directory and I 
describe it in ojb.properties as:
repositoryFile=/xxx.xml   The forward slash there is required.

With these parameters set, you can get your system running.  
If you are 
working with standalone and you are using eclipse, then you 
must place 
your ojb.properties in the top level of the java source 
folder.  That 
will cause it to end up in classes.

If you are trying to run some of your code (probably for testing or 
something) from a java application (main), you will need to have an 
ojb.properties that specifies a repository that does not 
haave the slash 
(differences in classloaders for app servers)
