JBoss 5.1.0 EAP.随机生成java.lang.NoClassDefFoundError

Question

在我们的EJB 3.0应用程序中,我们发生了随机发生的java.lang.NoClassDefFoundError.

它恰好发生在IDE中.

建立:

OS: Windows 7 32 Bit
Java JDK: 1.6.0_24 (32 Bit)?
IDE: IntelliJ 11.1?
App-Server: JBoss 5.1.0 EAP
EAR-Building with „maven-ear-plugin“?
WAR-Building with Maven „<packaging>war</packaging>“?
EJB-Building with Maven „<packaging>ejb</packaging>“ und „maven-ejb-?plugin“?

EAR看起来像这样:

xxx.ear
?   |___ META-INF
?   |    |___ application.xml (Information about EAR, EJB und WEB-Modul ?configured)?
?   |?
?   |___ xxxEJB.jar?
?   |    |?
?   |    |___ META-INF
?   |    |    |___ persistance.xml (JPA 1.0 configuration)?
?   |    |    |___ jboss.xml (JBoss-Config)?
?   |    |    |___ ejb-jar.xml (EJB 3.0 definition)?
?   |    |?
?   |    |___ country/yyy/xxx/.. (our own compiled classes)
?   |    |___ report/.. (JasperReport-Tamplates)
?   |    |___ quickfix/.. (QuickFixJ-configuration)
?   |    |___ all dependent libraries for our EJB 3.0 project, (74-jar-files)
?   | ?
?   |___ xxxWAR.war?
?        |?
?        |___ META-INF
?        |___ WEB-INF
?             |?
?             |___ lib?
?             |    |___ all dependent libraries for the Servlet-?project, (2-jar-files)
?             |___ classes?
?             |    |___ country/yyy/xxx/.. (our own compiled classes)
?             |___ web.xml (Servlet-configuration)?

Stacktrace看起来像这样:

JVM已使用选项:-verbose:class启动,以查看所有类加载操作.

文件"org/joda/time/tz/DefaultNameProvider"肯定在jar文件jar:file:/ C:/ Workarea/Projects/xxx-trunk/xxx-ear/target/xxx.ear!/xxxEJB.jar

建议:

我们感觉Quarz与它有关.因此,当安排了某些事情时,EJB 3.0远程无状态服务.有时会发生错误.

Quartz-Scheduler最初是在Servlet-Context中创建的,但大部分工作正常.

有人有同样的问题吗？

JBoss部署是通过IntelliJ JBoss插件完成的:

是不是,问题是因为我们使用的部署机制？我们使用intelliJ JBoss插件部署应用程序,因此JBoss说:

09:39:21,614 INFO  [MainDeployer] deploy, url=file:/C:/Workarea/Projects/xxx-trunk/xxx-ear/target/xxx.ear
09:39:33,613 INFO  [Ejb3DependenciesDeployer] Encountered deployment AbstractVFSDeploymentContext@2726974{vfszip:/C:/Workarea/Projects/xxx-trunk/xxx-ear/target/xxx.ear/xxxEJB.jar/}

Answer 1

当我们使用 IntelliJ IDEA JBoss-Run-Configuration 进行部署时，问题就会发生。

感谢 user1516873 的提示，通过 ANT/Maven 手动部署。

我们已经尝试过了。

我们引入了一个 ANT-Task，将 artefact xxx.ear 复制到 JBoss-Deploy-Folder 中。从那时起它工作正常，我们还没有得到 java.lang.NoClassDefFoundError 。

build.xml 看起来像这样：

<project name="xxx-deploy">
    <!-- Copy Artifact to JBoss-Deploy-Folder -->
    <target name="xxx-ear-deploy">
        <copy file="C:/Workarea/Projects/xxx-trunk/xxx-ear/target/xxx.ear"
              todir="C:/Workarea/_tools/jboss-eap-5.1.0-xxx/jboss-as/server/default/deploy"/>
    </target>
</project>
