Here is the client code I'm using to access the finder method


try {
Context context = new InitialContext();

MemberLocalHome home = (MemberLocalHome) context
.lookup(MemberLocalHome.JNDI_NAME);
Collection members = home.findByLastName("Patel");
Iterator i = members.iterator();
while (i.hasNext()) {
MemberLocal member = (MemberLocal) i.next();
System.out.println("************* "
+ member.getFirstName());
}
} catch (Exception e) {
e.printStackTrace();
}

Since it is a SQL Exception and not jboss parser exception, there is
something wrong with the way jboss is generating the SQL. I am not a
postgres user but maybe members is reserved? Try setting the log
setting to DEBUG just to see exacty what JBoss is asking your database.
