Anyone heard about intermittent problems in a frame-based page that uses .jsp, but no problems if .jsp page opened in it's own window? We have a frame-based page that allows visitors to submit a query to a goverment website (whose page is opened in our frame-based page). On occastion, we get the following error, which only seems to occur on the frame-based page, but not if we open the goverment page in its own window: 500 Servlet Exception java.lang.NullPointerException at _jsps._caseres__jsp._jspService(/graphics/cris/jsps/caseRes.jsp:44) at com.caucho.jsp.JavaPage.service(JavaPage.java:75) at com.caucho.jsp.Page.subservice(Page.java:485) at com.c   More>>

java.lang.NullPointerException at _jsps._caseres__jsp._jspService(/graphics/cris/jsps/caseRes.jsp:44)



So, what is on line 44 of your caseRes.jsp file, where the exception is apparently being thrown?
