Sorry. Of course, 4.0.5 is the JBOSS version. I mean Seam 1.2.1. OK, I think I see why the ExceptionFilter doesn't catch this. MultipartFilter is annotated with @Intercept(NEVER). I'm sure this is there for a very good reason. If I remove it, I get the following exception: 14:13:33,015 ERROR [[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception | java.lang.IllegalAccessException: Class org.jboss.seam.util.Reflections can not access a member of class org.jboss.seam.web.AbstractFilter with modifi | ers "" | at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:65) | at java.lang.reflect.Method.invoke(Method.java:588) | at org.jboss.seam.util.Reflections.invoke(Reflections.java:20) | at org.jboss.seam.intercept.RootInvocationContext.proceed(RootInvocationContext.java:31) | at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:57) | at org.jboss.seam.interceptors.RollbackInterceptor.aroundInvoke(RollbackInterceptor.java:34) | at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:69) | at org.jboss.seam.interceptors.MethodContextInterceptor.aroundInvoke(MethodContextInterceptor.java:27) | at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:69) | at org.jboss.seam.intercept.RootInterceptor.invoke(RootInterceptor.java:113) | at org.jboss.seam.intercept.JavaBeanInterceptor.interceptInvocation(JavaBeanInterceptor.java:151) | at org.jboss.seam.intercept.JavaBeanInterceptor.invoke(JavaBeanInterceptor.java:87) | at org.jboss.seam.web.MultipartFilter_$$_javassist_13.matchesRequestPath(MultipartFilter_$$_javassist_13.java) | at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:47) | at org.jboss.seam.web.SeamFilter.doFilter(SeamFilter.java:84) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.ajax4jsf.framework.ajax.xmlfilter.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:96) | at org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:220) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) | at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) | at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) | at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432) | at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) | at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) | at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) | at org.jboss.web.tomcat.tc5.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:156) | at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) | at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) | at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) | at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) | at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) | at java.lang.Thread.run(Thread.java:619) Is it possible to get exception handling to work with MultipartRequest?
