Initializer exception when running on windows

Question

Hi,
I've recently tried running one of my applications on windows and was
surprised to see that I was unable to create a PersistenceManager due to the
following exception:
Exception in thread "main" java.lang.ExceptionInInitializerError:
javax.jdo.JDOFatalDataStoreException: gnu/regexp/REException
NestedExceptions:
java.sql.SQLException: gnu/regexp/REException
at
com.techtrader.modules.jdo.impl.jdbc.JDBCPersistenceManagerFactory.setup(JDB
CPersistenceManagerFactory.java:174)
at
com.techtrader.modules.jdo.runtime.PersistenceManagerFactoryImpl.privateSetu
p(PersistenceManagerFactoryImpl.java:496)
at
com.techtrader.modules.jdo.runtime.PersistenceManagerFactoryImpl.getPersiste

at com.hcm.tools.jdo.JDOFactory.<clinit>(JDOFactory.java:101)
at com.hcm.security.SecurityHelper.getStocks(SecurityHelper.java:82)
I'm using a JDBC factory with these settings: optimistic true, retainValues
true, nonTransactionalRead true. This program runs correctly when I run it
on Linux. Could this be some kind of CLASSPATH problem with my windows
environment, or is this a problem with Kodo? What does this exception
mean? Thanks for your help.

Hi Pat,
The new stack trace looks a lot like the original, but maybe this will give
you a little more info. Here it is:

CPersistenceManagerFactory.java:174)Eric,
Can you provide me with a little more information? In JDOFactory,
please intercept the exception and add the following code:
catch (JDOFatalDataStoreException jfdse)
for (int i = 0; i < jfdse.getNestedExceptions ().length; i++)
jfdse.getNestedExceptions ().printStackTrace ();
throw jfdse;
and post the output. This will print out the full stack trace of the
nested exception.
I suspect that somehow, gnu.regexp.REException or some other
gnu.regexp class made its way into your persistent-types array, either
in the database (if you're using the JDO_SCHEMA_METADATAX table for
persistent type storage) or in your system.prefs. Run 'schematool
-action list' and see if there are any mentions of any gnu.regexp
classes there.
My hunch is based on the fact that we do not use the gnu.regexp
package anywhere in our code.
Additionally, I am sure that you and everyone else will be pleased to
know that we are in the process of auditing our exception-throwing
code to ensure that more detailed and useful messages are thrown in
exceptional circumstances.
