[opencms-dev] Java Action class for checking content changed/created

[Alessio Zurleni]

Sriman,

you cast the "resource" key from event data this way  (in case of event
resource modified) :

CmsResource  res = (CmsResource)<event object>.getData().get("resource");

U can access all resource informations with CmsResource methods.

Pay attention to the fact that getData method and keys are event
dependents, so have a
look at the org.opencms.main.I_CmsEventListener class.


Regards,

Alessio
