> In Struts Action we have used below code
> CoverageModel[] cs = (CoverageModel[])coverageCol.toArray(new CoverageModel[0]);
> f.set("coverage", cs);
> We are facing above exception after 6/8 hours of Application restart. . Some time we not facing above exception till 48hrs.
> 5 users accessing application day time.
> e.g.
> If we restart server @ 1 PM then try to login with new browser session at 7 PM or 9 PM, we are facing "java.lang.ClassCastException" on JSP page.
> If we restart Applcation Server then code is working fine. After restart, we not get null pointer class cast exception for next 6/8 hour.
> Please let me know if anybody has any suggestion/solution.
> Thanks and Regards,
