Problem:

Ambiguous Error Message when Distributed Caching via RMI is Enabled and Server is not Connected to a NetworkIf you’ve configured your ehcache.xml file for clustering via RMI and you are not connected to a network, ColdFusion will throw an error if you try to perform any caching activities.  This bit me at MAX when my network connection dropped before I started showing my examples.  When I tried running any of my examples, I got the following error:The web site you are accessing has experienced an unexpected error.Please contact the website administrator. error setting options  The error occurred in C:\_web\default\wwwroot\MAX2009\cache_get_put_function.cfm: line 11 : <cfset getArtists = cacheGet("artistQuery")>2 : 3 : ________________________________________Resources: •Check the ColdFusion documentation to verify that you are using the correct syntax.•Search the Knowledge Base to find a solution to your problem.Browser  Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3Remote Address  127.0.0.1Referrer  http://localhost/max2009/Date/Time  23-Oct-09 11:26 AMStack Trace at cfcache_get_put_function2ecfm561514261.runPage(C:\_web\default\wwwroot\MAX2009\cache_get_put_function.cfm:1) net.sf.ehcache.CacheException: error setting optionsat net.sf.ehcache.distribution.MulticastRMICacheManagerPeerProvider.init(MulticastRMICacheManagerPeerProvider.java:93)at net.sf.ehcache.CacheManager.init(CacheManager.java:241)at net.sf.ehcache.CacheManager.<init>(CacheManager.java:221)at net.sf.ehcache.CacheManager.create(CacheManager.java:415)at net.sf.ehcache.CacheManager.getInstance(CacheManager.java:436)at coldfusion.tagext.io.cache.ehcache.GenericEhcache.createCache(GenericEhcache.java:294)at coldfusion.tagext.io.cache.ehcache.GenericEhcache._getCache(GenericEhcache.java:288)at coldfusion.tagext.io.cache.ehcache.GenericEhcache.getCache(GenericEhcache.java:255)at coldfusion.tagext.io.cache.ehcache.GenericEhcache.get(GenericEhcache.java:72)at coldfusion.tagext.io.cache.CacheTagHelper.getFromCache(CacheTagHelper.java:226)at coldfusion.runtime.CFPage.CacheGet(CFPage.java:8025)at cfcache_get_put_function2ecfm561514261.runPage(C:\_web\default\wwwroot\MAX2009\cache_get_put_function.cfm:1)at coldfusion.runtime.CfJspPage.invoke(CfJspPage.java:231)at coldfusion.tagext.lang.IncludeTag.doStartTag(IncludeTag.java:416)at coldfusion.filter.CfincludeFilter.invoke(CfincludeFilter.java:65)at coldfusion.filter.ApplicationFilter.invoke(ApplicationFilter.java:342)at coldfusion.filter.RequestMonitorFilter.invoke(RequestMonitorFilter.java:48)at coldfusion.filter.MonitoringFilter.invoke(MonitoringFilter.java:40)at coldfusion.filter.PathFilter.invoke(PathFilter.java:87)at coldfusion.filter.LicenseFilter.invoke(LicenseFilter.java:27)at coldfusion.filter.ExceptionFilter.invoke(ExceptionFilter.java:70)at coldfusion.filter.BrowserDebugFilter.invoke(BrowserDebugFilter.java:74)at coldfusion.filter.ClientScopePersistenceFilter.invoke(ClientScopePersistenceFilter.java:28)at coldfusion.filter.BrowserFilter.invoke(BrowserFilter.java:38)at coldfusion.filter.NoCacheFilter.invoke(NoCacheFilter.java:46)at coldfusion.filter.GlobalsFilter.invoke(GlobalsFilter.java:38)at coldfusion.filter.DatasourceFilter.invoke(DatasourceFilter.java:22)at coldfusion.filter.CachingFilter.invoke(CachingFilter.java:53)at coldfusion.CfmServlet.service(CfmServlet.java:200)at coldfusion.bootstrap.BootstrapServlet.service(BootstrapServlet.java:89)at jrun.servlet.FilterChain.doFilter(FilterChain.java:86)at coldfusion.monitor.event.MonitoringServletFilter.doFilter(MonitoringServletFilter.java:42)at coldfusion.bootstrap.BootstrapFilter.doFilter(BootstrapFilter.java:46)at jrun.servlet.FilterChain.doFilter(FilterChain.java:94)at jrun.servlet.FilterChain.service(FilterChain.java:101)at jrun.servlet.ServletInvoker.invoke(ServletInvoker.java:106)at jrun.servlet.JRunInvokerChain.invokeNext(JRunInvokerChain.java:42)at jrun.servlet.JRunRequestDispatcher.invoke(JRunRequestDispatcher.java:286)at jrun.servlet.ServletEngineService.dispatch(ServletEngineService.java:543)at jrun.servlet.jrpp.JRunProxyService.invokeRunnable(JRunProxyService.java:203)at jrunx.scheduler.ThreadPool$ThreadThrottle.invokeRunnable(ThreadPool.java:428)at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66)This error only happens if you have RMI enabled in ehcache.xml and you aren’t connected to a network.  I don’t expect this would ever be a problem in a production environment, but it could pop up on development machines – especially if people develop disconnected.  At a minimum, I’d like to potentially see a more meaningful error message (even though you can narrow it down to RMI via the stack trace).
