[jira] [Commented] (AXIS2-4524) Caching BeanInfo in adb module's
BeanUtil improves performance
[ https://issues.apache.org/jira/browse/AXIS2-4524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13041583#comment-13041583 ]
Leon Fleysher commented on AXIS2-4524:
--------------------------------------
Do you guys think that a temporary workaround could be opening the adb jar into a directory and putting it in the classpath -- as I understood from AXIS2-4878 most of the time goes on scanning the axis2 jar(s) for non-existing bean info.
Or may be providing the optional bean info can help?
If none of the above -- may be moving to JAXB data binding can help resolving this problem?

> 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.
