Hi, I tried to configure Sentry with Tomcat but I failed. I would like to use the Java Logging appender. I guess I have to add sentry jars to bootstrap jars, so I created setenv.sh with this content:
jackson-core-2.8.10.jar sentry-1.7.29.jar slf4j-api-1.7.24.jar Of course I set logging.properties and sentry system properties too. It works (I see Sentry entries in server database), but the web application won't work anymore. Deploying fails with this error message: 10-Nov-2020 19:05:06.846 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive [/opt/tomcat/apache-tomcat-8.5.23/webapps/ReplicationService-0.0.1-SNAPSHOT.war] 10-Nov-2020 19:05:07.096 SEVERE [localhost-startStop-1] org.apache.catalina.core.ContainerBase.addChildInternal ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/ReplicationService-0.0.1-SNAPSHOT]] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:167) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:752) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:728) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:734) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:988) at org.apache.catalina.startup.HostConfig$DeployWar.run(HostConfig.java:1860) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.NoClassDefFoundError: javax/servlet/ServletContainerInitializer at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:368) at java.net.URLClassLoader$1.run(URLClassLoader.java:362) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:361) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338) at java.lang.ClassLoader.loadClass(ClassLoader.java:411) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1277) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1119) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at org.apache.catalina.startup.WebappServiceLoader.loadServices(WebappServiceLoader.java:188) at org.apache.catalina.startup.WebappServiceLoader.load(WebappServiceLoader.java:159) at org.apache.catalina.startup.ContextConfig.processServletContainerInitializers(ContextConfig.java:1622) at org.apache.catalina.startup.ContextConfig.webConfig(ContextConfig.java:1135) at org.apache.catalina.startup.ContextConfig.configureStart(ContextConfig.java:775) at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:299) at org.apache.catalina.util.LifecycleBase.fireLifecycleEvent(LifecycleBase.java:94) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5105) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) ... 10 more Caused by: java.lang.ClassNotFoundException: javax.servlet.ServletContainerInitializer at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 38 more If I remove setenv.sh then the application itself works, but Sentry doesn't. Do you have any idea why configuring Sentry jars cause this problem? Why Servlet API won't be found for the app? Thanks, Tamás
