If you use RMI/IIOP (Borland Application Server) then you need to "narrow"

Check the jboss.properties. there's a configuration for the RMI dynamic
classloading. I'm not sure if this is a case, but you can try.
By default it is (I think so):
java.
What's in the jndi.properties in JBoss conf/? I think you have to put the

and what does your server.log say about this? usually when you have all

Check if there are your update statements. Another way of debugging is to

Hi,
I think JAWS uses another scheme for obtaining connection (right, danch?):
Class.forName("interbase.interclient.Driver"); // force the JDBC driver to
be loaded
Connection con =
DriverManager.getConnection("jdbc:interbase://localhost/c:/prj/cerpsejb/data
/cerps.gdb", "sysdba", "masterkey");

What kind of exception did you get on server side?
Can you include mapping here?
And, for sure, storing date in String should not be the problem, as long as
JAWS is able to parse it. Also, I would suggest to use VARCHAR sql type
instead of CHAR (JAWS may have problems to parse the empty spaces).
As far as I know Tomcat automatically reloads the WEB-INF/classes and
WEB-INF/lib directories. So if your helper classes are in that folders, they
should be reloaded too. Classes from ${TOMCAT_HOME}/lib directory are loaded
on the start and are not reloaded during tomcat lifetime.

Sorry for not replying to the topic, I was busy by tuning the performance of
database (Firebird 0.9.4 p1). Now everything is ok. I don't use PosgreSQL
any longer, because even the 7.x version is slower than Firebird (also I am
using InterBase since the version 4.0, and I do like it! :))

No, if no jboss.xml found, it uses the standardjboss.xml in the
