Question

我们可以在JBoss（WildFly）上为我们的应用设置Application Insights in a Java web project。此步骤没有任何问题，我们可以在Azure门户上看到Web请求的监控数据。

但我们在安装the agent时获得了NoClassDefFoundError。

我试图解决这个问题几天没有任何成功。将代理jar添加到我们的应用程序依赖项（WEB-INF/lib）没有帮助。

作为旁注，我们可以使用New Relic Java代理成功运行我们的应用程序。似乎此问题的原因是Application Insights Java代理特有的。

我们的应用程序在Docker容器上运行：

主机：macOS High Sierra 10.13
Docker ：17.09
Docker容器操作系统：Ubuntu 16.04
Oracle JDK ：1.8
JBoss ：10.1.0.Final

Answer 1

在对Wildfly使用以下配置之前，我遇到了同样的问题

set JAVA_OPTS=%JAVA_OPTS% -javaagent:D:\workspace\applicationinsights-agent-2.1.1.jar
set JAVA_OPTS=%JAVA_OPTS% -Djboss.modules.system.pkgs=org.jboss.byteman,com.singularity,org.jboss.logmanager,com.microsoft.applicationinsights.agent
set JAVA_OPTS=%JAVA_OPTS% -Djava.util.logging.manager=org.jboss.logmanager.LogManager -Xbootclasspath/p:D:/wildfly-10.1.0.Final/modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-2.0.3.Final.jar

Answer 2

第三行无关紧要，但是第二行包含修复程序。我还必须在其中添加另一个值： -Djboss.modules.system.pkgs=org.jboss.byteman,com.microsoft.applicationinsights.agent,org.glowroot.instrumentation.api

您还可以在bin / standalone.conf中进行更改 if [ "x$JBOSS_MODULES_SYSTEM_PKGS" = "x" ]; then JBOSS_MODULES_SYSTEM_PKGS="org.jboss.bytemancom.microsoft.applicationinsights.agent,org.glowroot.instrumentation.api" fi

Application Insights Agent for Java在JBoss 10上导致NoClassDefFoundError
