Clinton Begin commented on IBATIS-500:
--------------------------------------
That's a really weird error... all three of those settings have been deprecated
and no longer do anything. I thought I left them in the DTD for backward
compatibility, but looking through the logs, I did indeed remove them. While
harsh, this is actually a good thing... :-/
I'll send a note to the list and close this issue.
> Failure when using maxRequests in settings and misleading error message
> -----------------------------------------------------------------------
>
> Key: IBATIS-500
> URL: https://issues.apache.org/jira/browse/IBATIS-500
> Project: iBatis for Java
> Issue Type: Bug
> Affects Versions: 2.3.1
> Reporter: Stephane Bailliez
>
> Putting that as major even though it is trivial since it affects migration
> and I guess users would scratch their head a bit more than necessary.
> Upgrade from 2.1.7 which had a sqlmap config with settings:
> {noformat}
> <settings
> cacheModelsEnabled="true"
> enhancementEnabled="false"
> lazyLoadingEnabled="false"
> maxRequests="512"
> maxSessions="128"
> maxTransactions="32"
> useStatementNamespaces="true"
> errorTracingEnabled="true"
> />
> {noformat}
> And got an error message that led me scratching my head for a while until I
> digged in the source code to figure out it was no more used. But the message
> is terribly misleading ( 'Attribute "maxRequests" must be declared for
> element type "settings".)
> Removing maxRequests, maxSession, maxTransactions from the settings solves
> the problem.
> {noformat}
