I have javax.transaction.UserTransaction in WEB-INF\lib\jta.jar
I don't understand why the error is happening ...
I can not have the jta.jar?
well, no, unless you are willing to work harder. jta is a server
component, so if you include it in your app and set classloading so
your app classes are loaded first, you are certain to run into
trouble. I thought the error you are getting was moderately clear
about the problem that is occuring.
I'm afraid my imagination is not up to thinking of a scenario in
which having a transaction api jar in your app would provide any
benefit. However, if you want to keep it, you can override the
effect of <inverse-classloading/> for particular packages using <non-
overrideable-classes> filters.
<non-overridable-classes>
<filter>javax.transaction.</filter>
</non-overridable-classes>
I'm generally against default restrictions on how an application
classloader can be set up but maybe we should think about including
javax.transaction in the default non-overridable-classes filters.
thanks
