Define common runtimes for web apps
Hi folks,
My requirement is to define common runtimes (several class paths) so that
several apps can use that by mentioning which class paths are using in web
app level. I suppose to do this by defining a runtime name with directory
path in an XML. I found by digging TomEE code that TempClassLoader is
responsible for loading classes and holding class loader definition. Hope
to override the behaviour of this class to achieve this requirement. Am I
in the right path? or any other better way to achieve this?
Thanks
Lakshman

(mvn:group:artifact:version), http path or any custom registered resolver

Hi Romain,
Thanks for the quick reply. In what format I should mention jar in jars.txt
file?
Thanks

Hi
can you add a WEB-INF/jars.txt in the wars needing this behavior? If so in
this file you can put /opt/tomee/libs/*.jar and all apps will inherit from
it.
Otherwise we have a ClassLoaderEnricher API which is intended for that
purpose but it is a bit lower level so can be harder to use (
tomee.classloader.configurer.clazz=my.company.ClassLoaderConfigurerImpl).
