From e6e0950a506d814415d8036e68e54d2034b6d3e7 Mon Sep 17 00:00:00 2001 From: Christof Rabensteiner Date: Thu, 22 Aug 2019 10:05:03 +0200 Subject: Fix: JAXB + Java >= 9 Class Loader Bug & Ensure Tomcat Deployment - Problem: Jaxb + JAVA >= 9 Runtime + Tomcat = ClassNotFoundException: ContextFactory. Reason: Apparently, jaxb uses the "wrong" classloader (the system classloader via the thread classloader) and this classloader does not know about jaxb api's and implementations at runtime since oracle decided to move jaxb* out of JRE. Solution: create a new thread, override the thread's "thread" classloader with the "class" classloader and do all jaxb interactions in that thread. See: https://sjhannah.com/blog/2018/11/21/jaxb-hell-on-jdk-9/ - Move "run jaxb interactions in own thread with class class loader" code into own component (JaxbClassNotFoundFix, runInTheadWithClassClassLoader) and wrap ClientFactory and Marshaller code into the "runInTheadWithClassClassLoader". - Ensure that app can be deployed in a Tomcat container (by following this guide: https://www.baeldung.com/spring-boot-war-tomcat-deploy) --- src/main/java/at/gv/egiz/moazs/backend/DeliveryRequestBackend.java | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src/main/java/at/gv/egiz/moazs/backend') diff --git a/src/main/java/at/gv/egiz/moazs/backend/DeliveryRequestBackend.java b/src/main/java/at/gv/egiz/moazs/backend/DeliveryRequestBackend.java index 72f8ba0..46b0c2c 100644 --- a/src/main/java/at/gv/egiz/moazs/backend/DeliveryRequestBackend.java +++ b/src/main/java/at/gv/egiz/moazs/backend/DeliveryRequestBackend.java @@ -11,7 +11,8 @@ import at.gv.zustellung.app2mzs.xsd.DeliveryRequestType; import at.gv.zustellung.msg.xsd.App2ZusePort; import at.gv.zustellung.msg.xsd.DeliveryRequestStatusType; import at.gv.zustellung.tnvz.xsd.TNVZServicePort; -import org.apache.log4j.Logger; +import org.slf4j.Logger; +import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Profile; import org.springframework.stereotype.Component; @@ -28,7 +29,7 @@ import static java.lang.String.format; @Profile("!cluster") public class DeliveryRequestBackend implements Consumer { - private static final Logger log = Logger.getLogger(DeliveryRequestBackend.class); + private static final Logger log = LoggerFactory.getLogger(DeliveryRequestBackend.class); private static final String MZS_PIPELINE_ERROR_MSG = "An error occured while processing the DeliveryRequest with AppDeliveryID=%s.
