I've gone over the SQL mapping twice; Granted I may be missing something, but I can't find it. The message that comes to the screen is no help since all it prints is a '?'.

org.hibernate.PropertyAccessException: exception getting propert
y value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) getter of us.tx.state.oag.PeopleSoft.hbm.HbmPsJobCodeTable.?

Looks like the code isn't supplying a substitution value.

Name and version of the database you are using:
Sybase 12.x

Do it again with hibernate.cglib.use_reflection_optimizer set to false, so that there's more info.

You might as well set hibernate.show_sql to true, while you're at it. The error might be obvious in the generated SQL.

Where would I put that setting? I'm using the Hibernate Deployer inside of JBoss. Does it go in the session factory definition, like this:

<mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.jca:service=HbmApplicationSecurity">
<!-- datasource settings -->
<attribute name="DatasourceName">java:/applicationSecurity</attribute>
<attribute name="Dialect">org.hibernate.dialect.SybaseDialect</attribute>
<!-- bind the hibernate service to jndi -->
<attribute name="SessionFactoryName">java:/hibernate/SfApplicationSecurity</attribute>
<attribute name="CacheProviderClass">org.hibernate.cache.HashtableCacheProvider</attribute>
<!-- logging -->
<attribute name="ShowSqlEnabled">true</attribute>
<attribute name="cglib.use_reflection_optimizer">true</attribute>
</mbean>

?

Found the setting syntax. Here's the mbean for each of my four session factories...

<mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.jca:service=HbmCommon">
<!-- datasource settings -->
<attribute name="DatasourceName">java:/common</attribute>
<attribute name="Dialect">org.hibernate.dialect.SybaseDialect</attribute>
<!-- bind the hibernate service to jndi -->
<attribute name="SessionFactoryName">java:/hibernate/SfCommon</attribute>
<attribute name="CacheProviderClass">org.hibernate.cache.HashtableCacheProvider</attribute>
<!-- logging -->
<attribute name="ShowSqlEnabled">true</attribute>
<attribute name="ReflectionOptimizationEnabled">false</attribute>
</mbean>

but it doesn't help. In fact, it doesn't seem to have any effect:

org.hibernate.PropertyAccessException: exception getting propert
y value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) getter of us.tx.state.oag.PeopleSoft.hbm.HbmPsJobCodeTable.?

Obviously that's not the place that hibernate is looking for it. Oh well, I guess that's a bust.

The ? thing is worrying, I've never seen anything like that before. Usually that exception happens when a type in your entity doesn't match the type in your mapping, and it's particularly common with composite keys. And since you have an unnamed composite key, there's lots of places where you could get this error. Go over your class and mapping, verify that every property in the mapping file has the appropriate non-final getter and setter in the java class. Consider using a named composite key (add the class="???" attribute to the composite-id element).
