Finally got it to work. Once I thought about it and looked at the
exception I realized that the mapping was being loaded. I looked into the
mapping file and found a space in front of the definition for SignInRole.
Conclusions: I can't see another way of using CASTOR on the j2ee 1.3
architecture other than binding the JDO to the jndi.
I see potential problems with the dynamic classloaders if another approach
is used.
Trying to put copies of the mapping files in the WEB-INF will work for
servlets but not for EJB's. I don't think EJB can see the WEB-INF/classes
directory - but I could be wrong. Putting the mapping files in the ejb
jars and the web-inf/classes directory is obviously a bad idea.
If weblogic startup classes are used then there are additional problems.
Correct me if I'm wrong but the cleanest approach, the path of least pain,
is binding a jdo to the jndi tree. Hopefully there aren't any performance
hits with this approachs.
Hope someone has a little less pain than I had with this.
Its saturday, my immediate problem is SOLVED, and I am outta here.

JNDI/JDO: can't find a class when using a

Please respond to
castor-dev
Machine 160.129.239.236 is where you mount the JDO into the JNDI. Is it
also the machine from which you try to access that JDO?
If not, I have never gotten that part to work (although I get a different
error). I have only ever been able to access the JDO from the same machine
as where it is bound into the JNDI tree.
I ask because you are explicitly giving the connect parameters on
InitialContext creation which is not necessary if on the same box (in the
same wl instance).

Subject: [castor-dev] JNDI/JDO: can't find a class when using a jdo
retrieved from jndi
I'm using weblogic 6.1 and have verified that the jdo is being bound to the
jndi tree.
Its also being retrieved as is verifiable from the stack trace below.
Maps and database files are fine. This was working prior to my trying the
jndi/j2ee method
All classes except the stubs and skeltons for the ejbs are in the
serverclasses directory which is in the system classpath.
Another copy of the files are in WEB-INF/classes
The class in question SignInRole is also in the ejb jar
Any ideas
catch (DatabaseNotFoundException e)

EDWhiteboardLog.error("**** BaseDAO constructor : DB not found",e);
e.printStackTrace();
throw e;

This is displayed the error displayed int catch above
