Right, I would also expect these three files in conf/


Is it possible you can post the startup log output?

If you can set the "" log category to  
"DEBUG" that should print the location of the and files, which will help us see where they are ending  
up.  You can set that via the InitialContext properties or as a system  
property (or in your file, but it sounds like that  
is getting overwritten).

That is very interesting.  Our check for the file  
uses this logic:

     File confDir = SystemInstance.get().getBase().getDirectory("conf");
     File loggingPropertiesFile = new File(confDir,  

So all should be good if openejb.base (or openejb.home) is set.  The  
other strange thing is I was pretty certain we didn't aggressively  
create a "logs" directory if you didn't already have one and instead  
resorted to logging to System.out when there wasn't a "logs" dir under  

On a side note, you shouldn't need to setup a directory structure to  
get configuration control if you don't want to.  Everything you can  
configure in an openejb.xml file and file can be  
configured in properties that are in a file in the  
classpath, feed to the InitialContext as properties, or set as system  
properties.  And then you really only need to specify what you want  
handled differently than what OpenEJB would normally do.

Here's an example file you could include in your  

   # set the initial context factory
   java.naming.factory.initial =  

   # change some logging
   log4j.category.OpenEJB.options = debug
   log4j.category.OpenEJB.startup = debug
   log4j.category.OpenEJB.startup.config = debug

   # create some resources
   movieDatabase = new://Resource?type=DataSource
   movieDatabase.JdbcDriver = org.hsqldb.jdbcDriver
   movieDatabase.JdbcUrl = jdbc:hsqldb:mem:moviedb

   # override properties on your "movie-unit" persistence unit
   movie-unit.hibernate.dialect = org.hibernate.dialect.HSQLDialect

   # set some openejb flags
   openejb.jndiname.format = {ejbName}/{interfaceClass}
   openejb.descriptors.output = true
   openejb.validation.output.level = verbose

Hope this helps!  Happy to take a look at your log info when you get it.
