I am trying to configure my web site to use form authentication, with the passwords and login ids being stored in an Oracle database. When I try to authenticate, however, org.apache.cataline.realm.JDBCRealm getPassword is throwing a java.sql.SQLExcpetion, saying invalid column name.
I am assuming that the string I've entered for userCredCol is not mapping to a column in the table I've entered as userTable. However, I've copied and pasted the name of the password column into the <Realm ...> element field, userCredCol.
Any thoughts on how I continue to troubleshoot this? Can I assume that JDBCRealm did find the column associated with userNameCol?

It turns out the the userNameCol in my server.xml did not match the name of the column in the database, so that's why I was getting the "Invalid Column" error.
I had also misunderstood the error message that I was getting. Because it first said, "org.apache.catalina.realm.JDBCRealm getPassword, then threw an invalid column name exception, I thought that this meant that the password column in my database did not match the name I had entered as userCredCol in my Realm element, so I was overly focused on this. However "JDBCRealm getPassword" must refer to the entire authentication process, not just the attempt to get the database's password.
