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.
