1. Re: 4.2.2 Switching name cases from proper case to camel cas
Please post the entire exception stacktrace. As for the case-sensitivity, i think its more on the DB server side than your java code. Make sure that you have correct settings on the DB server to allow case insensitive column names.

2. Re: 4.2.2 Switching name cases from proper case to camel cas
The database is case sensitive base on other requirements. (Not my decision.) However, JBoss is changing the case on many names when the beans are deployed. We did not have this problem until we upgraded from 4.0.5 to 4.2.2. Something in 4.2.2 is forcing names to camel case. We are having to put @Table and @Column tags in all entities. After tagging all of the methods the error goes away. It also camel cased some names in the WSDL that are proper case in the bean.

3. Re: 4.2.2 Switching name cases from proper case to camel cas
JBoss lets Hibernate (the persistence provider) to handle the JPA entities. I guess, you should post this question in the Hibernate forums. The versions of Hibernate in JBoss-4.0.5 and JBoss-4.2.2 have changed, so maybe that's the reason you don't see this behaviour in 4.0.5

4. Re: 4.2.2 Switching name cases from proper case to camel cas
The entity names in the WSDL are also being camel cased. Which really makes it look like the issue is in JBoss. If I add tags, I can force most of the names in the WSDL and DB to match the code case, but that requires touching a lot of code. The 4.0.5 version of JBoss did not require these tags to maintain the case on the names. In most of the languages we use to talk to JBoss, case is important.
Where are the names read out of the jar/ear when a bean is deployed? Could something have been added there to camel case the names?
