jboss未能定義類javax.jms.JMSException

Question

我是JBoss的新手。 WAS上有一個Ear文件可以工作。但是當我在JBoss EAP 7.1上嘗試時，它給了我下面的錯誤。

14:15:18,640 WARN [org.jboss.modules] (MSC service thread 1-6) Failed to define class javax.jms.JMSException in Module "deployment.xxx.ear.yyy.war:mai

從研究，它似乎只是接口的依賴問題。

<dependency> 
    <groupId>javax</groupId> 
    <artifactId>javaee-api</artifactId> 
    <version>6.0</version> 
    <scope>provided</scope> 
</dependency> 

所以我改成

<dependency> 
    <groupId>org.apache.openejb</groupId> 
    <artifactId>javaee-api</artifactId> 
    <version>6.0-5</version> 
    </dependency> 

，但沒有運氣。我也在尋找像j2ee.jar這樣的jar。我可以在JBoss運行時找到一個jboss-ejb-api_3.2_spec-1.0.0.Final-redhat-1.jar。但它不包含任何關於javax.jms。*的內容。

另外我看了一堂課。使用帶有內容的jboss-deployment-structure.xml修補ear文件以消除雙重類加載。

<jboss-deployment-structure> 
    <ear-subdeployments-isolated>true</ear-subdeployments-isolated>  
</jboss-deployment-structure> 

仍然不起作用。有什麼建議麼？

javax.javaee-api.6.0 maven依賴關係有一個單一的well documented問題 - 它需要的任何實現類的字節代碼已被剝離，導致java.lang.ClassFormatError。

您看到這種情況的原因是因爲即使您的dependency說<scope>provided</scope>，此jar的副本泄漏到您的應用程序部署的某處。你需要擺脫它。

完成此操作後，您可以將依賴關係升級到<version>7.0</version>，這樣不存在此問題（對於依賴它的單元測試，這通常只是一個問題）。
