Non-reproducible after clearing the JSP cache (see workaround section for details)
解决办法
Please try after deleting the JSP cache.1. cd <install location>/arcgis/server10.0/java/manager/service/managerappserver/work/Catalina/localhost2. remove folder arcgis_rest (JSP cache will be regenerated again) 3. It is not required to restart the server/service.4. refresh the html page (on port:8399) in the browser.If REST handler is deployed on a external appserver, delete the JSP cache on that server.
