Yep, I've looked. There isn't any exception in there.

Hi, Richard! Have you checked tomcat logs? catalina.out namely. They can shed some light.

Most of my stuff is on 5.3, so I haven't been able to dig very deep on this, and I'm not quite sure what I'm missing. I'm running Tomcat 8.5.x. Now, it appears that might be from classpath:org/apache/tapestry5/corelib/pages/ExceptionReport.tml. But something else must be generating the error. I've been able to make it go away with a restart of Tomcat, but not of just the app itself. I'm fairly confused. I think that the exception being reported isn't the actual root cause, but rather the exception that is reported due to an error with reporting the actual exception. 2018-05-23 17:57:10,697 [ERROR] ioc.Registry java.lang.NullPointerException 2018-05-23 17:57:10,698 [ERROR] ioc.Registry Operations trace: 2018-05-23 17:57:10,698 [ERROR] ioc.Registry [ 1] Handling page render request for page Index 2018-05-23 17:57:10,698 [ERROR] ioc.Registry [ 2] Constructing instance of page class edu.ndsu.eci.international_capstone_exchange.pages.Index 2018-05-23 17:57:10,698 [ERROR] ioc.Registry [ 3] Creating ComponentAssembler for edu.ndsu.eci.international_cap stone_exchange.pages.Index 2018-05-23 17:57:10,698 [ERROR] ioc.Registry [ 4] Parsing component template classpath:edu/ndsu/eci/international_capstone_exchange/ pages/Index.tml 2018-05-23 17:57:10,712 [ERROR] TapestryModule.RequestExceptionHandler Processing of request failed with uncaught exception: org.apache.tapestry5.ioc.internal.OperationException org.apache.tapestry5.ioc.internal.OperationException at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.logAn dRethrow(OperationTrackerImpl.java:186) at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.invok e(OperationTrackerImpl.java:90) at org.apache.tapestry5.ioc.internal.PerThreadOperationTracker. invoke(PerThreadOperationTracker.java:72) at org.apache.tapestry5.ioc.internal.RegistryImpl.invoke(Regist ryImpl.java:1260) at org.apache.tapestry5.internal.services.TemplateParserImpl.pa rseTemplate(TemplateParserImpl.java:57) at $TemplateParser_95423bef7.parseTemplate(Unknown Source) at org.apache.tapestry5.internal.services.ComponentTemplateSour ceImpl.parseTemplate(ComponentTemplateSourceImpl.java:190) at org.apache.tapestry5.internal.services.ComponentTemplateSour ceImpl.getTemplate(ComponentTemplateSourceImpl.java:162) at $ComponentTemplateSource_95423bef6.getTemplate(Unknown Source) at org.apache.tapestry5.internal.pageload.PageLoaderImpl$4.invo ke(PageLoaderImpl.java:258) at org.apache.tapestry5.internal.pageload.PageLoaderImpl$4.invo ke(PageLoaderImpl.java:251) at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.invok e(OperationTrackerImpl.java:82) at org.apache.tapestry5.ioc.internal.PerThreadOperationTracker. invoke(PerThreadOperationTracker.java:72) at org.apache.tapestry5.ioc.internal.RegistryImpl.invoke(Regist ryImpl.java:1260) snip Caused by: java.lang.NullPointerException at org.apache.tapestry5.internal.services.XMLTokenStream.getLoc ation(XMLTokenStream.java:487) at org.apache.tapestry5.internal.services.SaxTemplateParser.par se(SaxTemplateParser.java:181) at org.apache.tapestry5.internal.services.TemplateParserImpl$1. invoke(TemplateParserImpl.java:61) at org.apache.tapestry5.internal.services.TemplateParserImpl$1. invoke(TemplateParserImpl.java:58) at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.invok e(OperationTrackerImpl.java:82) ... 102 more 2018-05-23 17:57:10,804 [ERROR] ioc.Registry java.lang.NullPointerException 2018-05-23 17:57:10,804 [ERROR] ioc.Registry Operations trace: 2018-05-23 17:57:10,804 [ERROR] ioc.Registry [ 1] Constructing instance of page class org.apache.tapestry5.corelib.pages.ExceptionReport 2018-05-23 17:57:10,804 [ERROR] ioc.Registry [ 2] Creating ComponentAssembler for org.apache.tapestry5.corelib.pages.ExceptionReport 2018-05-23 17:57:10,804 [ERROR] ioc.Registry [ 3] Parsing component template classpath:org/apache/tapestry5/corelib/pages/ExceptionReport.tml To add to the confusion, I've never had the error trigger when running on my workstation using Tomcat, just as installed on our server. Almost makes me think that it is trying to write somewhere that is causing problems. I just restarted Tomcat, and it now loads. How do I find root cause? I've turned logging all the way up, and then there is too much noise. Since I can't get it to trigger on my workstation, I can't get a debugger connected to figure it out from there.
