當只有weblogic 8.1服務器運行時,我不得不在服務器上運行簡單的定期任務,因此需要在weblogic上運行該任務。Weblogic 8.1 - 最簡單的耳朵 - 不可理解的錯誤信息
我從創建最簡單的耳朵開始,即運行一個類。我在其他項目中發現的啓動類的調用weblogic-application.xml中:
<?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>
正如我瞭解,Java代碼必須在單獨的EJB項目,所以我創建了項目僅包含myStartupClass,並將其添加爲類型爲ejb的maven依賴項。我用耳朵建設Maven的耳插件:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-ear-plugin</artifactId>
<configuration>
<defaultLibBundleDir>lib</defaultLibBundleDir>
</configuration>
</plugin>
最後,耳朵是建立,我部署它,什麼也沒有說消息:
[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..
我檢查日誌找一些細節,但可惜的是他們給我任何提示,從我想要什麼的WebLogic:

你能不能給我一個提示我做錯了什麼,在哪裏開始呢?我試圖找到類似於我的案例(沒有Web應用程序,沒有遠程EJB服務,只有簡單的定期任務,用maven構建)的一些教程,但我找不到任何匹配...任何提示將不勝感激。
在另一個項目中,來自EAR的類被調用,並且正在進行初始配置。但是,我有可能濫用這個功能,我應該做其他的事情......但是什麼? – 2012-02-23 14:19:19
嗯,但是你確定那個類(從另一個項目工作的類)是否也沒有部署在WebLo類路徑的JAR中? – 2012-02-23 14:20:58
無論如何,我不是WebLo的專家,但是如果你想在你的項目中有一個類,當項目被部署時調用它,爲什麼不做一個普通的香草javax.servlet.ServletContextListener? – 2012-02-23 14:22:26
