2. Re: JBoss 3.2.5 MySQL 4.0 finder Method gives a Finder Excep
pintovc Nov 6, 2006 12:47 AM (in response to pintovc)I performed a "Select * from userprofile" from the MySQL query browser and it worked fine. The mysql check shows that the database is running fine. The JBoss log indicates that it is able to locate and connect to mySQL datasource.

3. Re: JBoss 3.2.5 MySQL 4.0 finder Method gives a Finder Excep
pintovc Nov 6, 2006 3:07 AM (in response to pintovc)So to finally help myself I downloaded the source for JBoss 3.2.5 and am tracing through it. It appears that the exception is thrown on the invocation of the findByUserName method in the TxManager class.
I have not been able to trace further, but it bring to my attention how there can never be a dearth of documentation. And open source is just a poor step above closed source in the absence of good documentation.
:-) Enough said lest I induce myself to start documenting the JBoss code :-) -

6. Re: JBoss 3.2.5 MySQL 4.0 finder Method gives a Finder Excep
pintovc Nov 20, 2006 12:19 AM (in response to pintovc)An update:
So I figured I would try the new JBoss IDE and see if it would resolve my issues. Unfortunately I get the same error.
Hss anyone got the JBoss CMP to work on MySQL? IF kindly provide any help you believe may be useful -

8. Re: JBoss 3.2.5 MySQL 4.0 finder Method gives a Finder Excep
pintovc Nov 22, 2006 10:14 PM (in response to pintovc)Well I finally figured it out. A small piece of advice for those of you trying it out, JBoss is even more picky than hibernate. Check the capitalization of your database table column names, class attribute names and the mapping between them.
If oyu need help you can contact me at pintovc at hotmail dot com
