Hi Raj, I'm only guessing, but it looks like the version of OC4J that's embedded in your version of JDeveloper does not support the "handlePageException(Throwable)" method. As far as I can tell, this method was introduced in J2EE 1.3. So I guess your JDeveloper only supports the "handlePageException(Exception)" method. I suppose this is not sufficient for your purposes, eh? I see there is a 126.96.36.199 Maintenance Release of JDeveloper available for download from Oracle's Technet Web site. Perhaps this will fix your problem? (Since I don't use JDeveloper, I can't say for sure :-) Good Luck, Avi.
