Re: OJB and Oracle 9ias

[Wayne Kidd]

This is the right place OJB instead of ojb.  I am sorry if I misled you.

The place to understand is in the CVS for the following 2 classes

org.apache.ojb.broker.util.configuration.impl.ConfigurationAbstractImpl

and

org.apache.ojb.broker.util.configuration.impl.OjbConfiguration

They actually do this stuff. 

You will get an error message if that file is not found

       catch (Exception ignore)
       {
           LoggerFactory.getBootLogger().error("Cannot get OJB properties file, use default 
settings!");
           properties.put("valid", "false");
       }
   }
If you do not get this error, the properties file is found and the next thing to be concerned about is whether the 
following parameter was found in the properties file.  If not, it will default to repository.xml as shown in the code below



repositoryFilename = getString("repositoryFile", "repository.xml");

       
It will then try to read that file.

I have it in WEB-INF/classes.  Is it possible that it's not being found
because the file is OJB.properties instead of ojb.properties?

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).
