在SAR文件中的java.lang.ClassNotFoundException JBOSS AS 7.1.1

Question

我想部署一個sar文件，但是我得到一個與java.lang.ClassNotFoundException相關的錯誤。 我SAR文件是

10:46:27,697 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-7) MSC00001: Failed to start service jboss.mbean.service."backend.actipstation:service=SnmpStationService1".start: org.jboss.msc.service.StartException in service jboss.mbean.service."backend.actipstation:service=SnmpStationService1".start: JBAS017222: Failed to execute legacy service start() method at org.jboss.as.service.StartStopService.start(StartStopService.java:56) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [rt.jar:1.7.0_65] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [rt.jar:1.7.0_65] at java.lang.Thread.run(Thread.java:745) [rt.jar:1.7.0_65] Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [rt.jar:1.7.0_65] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) [rt.jar:1.7.0_65] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.7.0_65] at java.lang.reflect.Method.invoke(Method.java:606) [rt.jar:1.7.0_65] at org.jboss.as.service.AbstractService.invokeLifecycleMethod(AbstractService.java:52) at org.jboss.as.service.StartStopService.start(StartStopService.java:54) ... 5 more Caused by: java.lang.NoClassDefFoundError: org/snmp4j/smi/Variable at cl.auter.sictrav.comunicacion.snmp.backend.SnmpStation.startService(SnmpStation.java:154) at cl.auter.sictrav.comunicacion.snmp.backend.SnmpStationService.start(SnmpStationService.java:11) ... 11 more Caused by: java.lang.ClassNotFoundException: org.snmp4j.smi.Variable from [Module "deployment.sictrav3_actstationservice.sar:main" from Service Module Loader] at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:190) [jboss-modules.jar:1.1.1.GA] at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:468) [jboss-modules.jar:1.1.1.GA] at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:456) [jboss-modules.jar:1.1.1.GA] at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:398) [jboss-modules.jar:1.1.1.GA] at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:120) [jboss-modules.jar:1.1.1.GA] ... 13 more

我SAR文件具有這種結構

+ actstationservice.sar 
|-cl/ 
    |- /* compiled class files here */ 
| snmp4j-1.11.1.jar 
|-META-INF/ 
    |- jboss-service.xml 
    |- jboss-deployment-structure.xml 

JBoss的部署，structure.xml

<?xml version="1.0" encoding="UTF-8"?> 
<jboss-deployment-structure> 
<deployment> 
    <resources> 
     <resource-root path="snmp4j-1.11.1.jar"></resource-root> 
    </resources> 
    <dependencies> 
     <module name="org.snmp4j" export="true" /> 
    </dependencies> 
</deployment> 
</jboss-deployment-structure> 

我的Manifest.MF

Manifest-Version: 1.0 
Dependencies: org.snmp4j export,org.hibernate 

我也有庫/ lib文件夾內

我錯過了什麼？

Answer 1

sar文件不包含META-INF中的jboss-deployment-structure.xml。我添加了它，它起到了魅力的作用。

Answer 2

請嘗試將snmp4j-1.11.1.jar作爲模塊，而不是直接將其作爲jboss-deployment-structure中的資源根。如何做到這一點的詳細信息可以在這裏找到：https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7

，你可以嘗試做的另一件事情是修改的依賴是如何在JBoss中部署，structure.xml定義 -

<jboss-deployment-structure> 
    <deployment> 
    <dependencies> 
     <module name="deployment.sictrav3_actstationservice.sar.snmp4j-1.11.1.jar" /> 
    </dependencies> 
    <resources> 
     <resource-root path="snmp4j-1.11.1.jar" /> 
    </resources> 
    </deployment> 
</jboss-deployment-structure>

希望這有助於。
