Weblogic 8.1-最简单的ear-不可理解的错误消息



当只有weblogic 8.1服务器在运行时,我不得不在服务器上运行简单的定期任务,所以要求在weblogic上运行该任务。

我从创建最简单的ear开始,它将运行一个类。我在其他项目中发现了weblogic-application.xml中启动类的调用:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE weblogic-application 
          PUBLIC "-//BEA Systems, Inc.//DTD WebLogic Application 8.1.0//EN" 
          "http://www.bea.com/servers/wls810/dtd/weblogic-application_2_0.dtd">
<weblogic-application>
    <startup>
        <startup-class>myStartupClass</startup-class>   
        <startup-uri>my-ejb.jar</startup-uri>
    </startup>
</weblogic-application>

正如我所理解的,java代码必须在单独的EJB项目中,所以我创建了只包含myStartupClass的项目,并将其添加为EJB类型的maven依赖项。我正在使用maven ear插件构建ear:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-ear-plugin</artifactId>
            <configuration>
                <defaultLibBundleDir>lib</defaultLibBundleDir>
            </configuration>
        </plugin>

最后,耳朵建成了,我正在部署它,没有任何信息:

[Deployer:149233]An unexpected error was encountered during the deployment process.
    [Deployer:149033]preparing application finder-ear-1 on myserver
    [Deployer:149033]failed application finder-ear-1 on myserver
    [Deployer:149034]An exception occurred for task [Deployer:149026]Deploy application finder-ear-1 on myserver.: [Deployer:149233]An unexpected error was encountered during the deployment process..

我检查了日志以找到一些细节,但不幸的是,它们没有给我任何weblogic想要我做什么的提示:

你能给我一个提示吗?我做错了什么?从哪里开始?我试图为类似于我的案例找到一些教程(没有web应用程序,没有远程EJB服务,只有简单的定期任务,使用maven构建),但我找不到任何匹配的东西。。。如有任何提示,不胜感激。

我认为,由于启动类的目的是在部署某个EAR之前执行,因此需要将该类放在EAR文件之外。因此,您可以尝试将所有这些内容保留在weblogic-application.xml文件中,但将启动类打包在一个标准jar文件中,该文件部署在weblogic的类路径dir(%WL_HOME%\server\lib)中
