如何在glassfish中使用第三方库？ [英] How to use 3rd party libraries in glassfish?

问题描述

我需要从我的EJB3应用程序连接到一个MongoDB实例，运行在glassfish 3.0.1上。 Mongo项目提供了一组驱动程序，我可以在独立的Java应用程序中使用它们。

I need to connect to a MongoDB instance from my EJB3 application, running on glassfish 3.0.1. The Mongo project provides a set of drivers, and I'm able to use them in a standalone Java application.

我如何在Java EE应用程序中使用它们？或者也许更好的措辞：当我的应用程序运行在EJB容器中时，如何使第三方库可用？

How would I use them in a Java EE application? Or maybe better phrasing: how would I make a 3rd party library available to my application when it runs in an EJB container?

目前，我得到一个java .lang.NoClassDefFoundError当部署一个
尝试从库中导入的bean时：

At the moment, I'm getting a java.lang.NoClassDefFoundError when deploying a bean that tries to import from the library:

[#|2010-03-24T11:42:15.164+0100|SEVERE|glassfishv3.0|global|_ThreadID=28;_ThreadName=Thread-1;|Class [ com/mongodb/DBObject ] not found. Error while loading [ class mvs.core.LocationCacheService ]|#]

我尝试添加它到网络Beans项目（属性 - >库 - >编译 - >添加Jar，启用'Package'），我也尝试手动将jar文件复制到$ GF_HOME / glassfish / domains / domain1 / lib（其中mysql连接器已经驻留） 。

I tried adding it to the NetBeans project (Properties -> Libraries -> Compile -> Add Jar, enable 'Package'), and I also tried manually copying the jar file to $GF_HOME/glassfish/domains/domain1/lib (where the mysql-connector already resides).

我需要向容器注册库吗？通过注释引用它？扩展容器的类路径以包含库？

Do I need to 'register' the library with the container? Reference it via Annotation? Extend the classpath of the container to include the library?

推荐答案

嗯...不应该把这个驱动程序放入 glassfishv3 / glassfish / domains / domain1 / lib / ext ？

Hmm... Shouldn't you put this "driver" in glassfishv3/glassfish/domains/domain1/lib/ext?
