Subject [jira] Commented: (AXIS2-4524) Caching BeanInfo in adb module's BeanUtil improves performance
Date Fri, 24 Dec 2010 12:35:47 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-4524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12974903#action_12974903

Amila Chinthaka Suriarachchi commented on AXIS2-4524:
-----------------------------------------------------

I think the proper way of doing this is to populate these details at the deployment time keep
it in Axis description hierarchy and use it in parsing and serializing. 

Sometimes back I did the axis2-rmi to fix all those issues. But most of the people did not
like it since POJO was there :).

> I've detected that org.apache.axis2.databinding.utils.BeanUtil class can be improved
for performance. It seems that invoking Introspector.getBeanInfo(Class,  Class) takes a lot
of time. By caching java.beans.BeanInfo in this class it doubles up (at least) the performance,
especially when returning a big dataset. I changed this myself and saw a great deal of performance
improvement.
