Subject Re: Login fails, then works subsequently (Tomcat 7)
Date Wed, 21 Dec 2011 22:23:07 GMT
Here is the line from <GlobalNamingResources> in server.xml:

 <Resource name="jdbc/aaaaaaaaaaaaaaaaaaaa.com" auth="Container"
type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000"
removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true"
username="*******" password="*********"
driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://
127.0.0.1/aaaaaaaaa?autoReconnect=true"/>

The http trace would show if the id/pw were different.  But that would
pretty much imply that the browser is messing up what it sends.  I guess
that's always a possibility.  But I haven't changed browsers in months.
And it's sending a saved id/pw in all cases.  the login form appears, and
the id/pw is already filled in.  I hit enter.  I get the logon-failed form,
I hit enter again, and it logs me in.  I just don't see how the browser
after all of these years would just all of a sudden start sending bad id/pw
once, and the start coincides with new version of TC.  Again, I guess
anything could happen.  But I think it's unlikely.  This worked fine for
years with the same db and the same browsers.  Drop in a new TC and it
starts failing.

I don't have a custom realm.  I'm just using the default auth code in TC.
I'm not really excited about writing my own realm code for this or
modifying TC source and rebuilding TC from scratch.  Anybody got a jar file
I can drop in that has realm debug stuff already in it?

Thanks.

Jerry
