如何使用jbi-maven-plugin集成servicemix共享庫？

Question

我使用ServiceMix 3.5 我有多個ServiceAssemblies，每個ServiceUnit。 服務單位有許多共同的圖書館，所以我在maven pom中用'提供'範圍標記它們。 共享庫包含我想要服務單元共享的所有庫。 我根據以下Maven pom.xml中的內置，但效果是一個簡單的異常：

拋出java.lang.ClassNotFoundException： org.apache.commons.dbcp.BasicDataSource類加載器 org.apache.xbean。 spring.context.FileSystemXmlApplicationContext

我可以做什麼（可能使用jbi-maven-plugin）以便我的服務單元使用共享庫中的jar？

共享庫服務單元POM：

服務集合的出海我想你誤會JBI組件/ SharedLib/SA/SU或JBI是如何工作的類加載器的一些概念，請大家看看here得到更多細節。

我不明白「共享庫服務單元pom」是什麼意思，按照JBI規範，SharedLib不應該有任何服務單元，它只是由JBI組件引用，如servicemix-camel，所有servicemix JBI組件僅引用一個名稱爲servicemix-shared的默認SharedLib。

類org.apache.commons.dbcp.BasicDataSource是公地dbcp.jar但公地dbcp.jar不在smx3.x默認sharedlib ServiceMix的共享 - $ {}版本-installer.zip ，所以這意味着默認情況下，除非您在SU的xbean.xml中明確添加，否則所有servicemix-camel su都不能看到此類。
