本文介绍了WebLogic中的JEE共享库的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我将我的应用程序移植到WebLogic作为企业库，以便我的EJB和MDB可以调用其中的代码。
I am porting my application to WebLogic as an Enterprise Library so that my EJB and MDB can invoke code in it.
我为Lib1.ear和Lib2.ear选择了一个EAR包装，其中包含APP-INF / lib目录并且两者都有100个罐子。我还更新了两者的 MANIFEST.MF 以包含规范 - 版本和实施 - 版本。两者都已成功部署并可供使用。
I have chosen a EAR packaging for both say Lib1.ear and Lib2.ear which contains APP-INF/lib directory and have 100's of jars in both. I also have updated the MANIFEST.MF of both to contains Specification-Version and Implementation-Version. Both are deployed successfully and available to be used.
现在我更新了包含我的EJB和MDB的耳朵，并在 weblogic-application中添加了以下内容。 xml ;
Now I updated my ear which contains my EJB and MDB and added following in weblogic-application.xml;
<wls:library-ref>
<wls:library-name>Lib1</wls:library-name>
<wls:specification-version>18</wls:specification-version>
</wls:library-ref>
<wls:library-ref>
<wls:library-name>Lib2</wls:library-name>
<wls:specification-version>18</wls:specification-version>
</wls:library-ref>
但是当我部署我的EAR（其中包含EJB等）时，它在第一步失败时抱怨它没有找到接口，它是在我的EJB实现之一中定义并打包在 Lib1.ear 共享库中的那。我已启用调试日志，但我无法从WebLogic中找到任何指引我到正确路径的信息。我的所有EJB都使用远程名称等进行初始化，但后来我的日志中出现单行错误，后跟 ClassNotfoundException ;
But when I am deploying my EAR (which constains EJB etc) it fails on the first step complaining that it does not find an interface which is defined and packaged in Lib1.ear shared lib as my one of my EJB implements that. I have enabled debug log but I am unable to find any information from WebLogic which directs me to the right path. All my EJB are initialising with the remote name etc but then I get a single line error in my log followed by a ClassNotfoundException;
<28-Nov-2017 15:26:18,005 o'clock GMT> <Error> <J2EE> <BEA-160228> <AppMerge failed to merge your application. If you are running AppMerge on the command-line, merge again with the -verbose option for more details. See the error message(s) below.>

我错过了什么吗？
推荐答案
只为其他人回答，以便他们能够快速完成这项工作。如果打包共享库，则WAR只能由其他WAR引用而不是EAR引用。所以我将我的包更新为EAR。正如我上面所说的，我想分享我的库，这些是POJO，我必须使用以下结构，我的EAR能够成功地看到类。
Just to answer for others so that they can get this done quickly. If shared lib is packaged as WAR can only be referenced by other WAR's not an EAR. So I updated my package to be an EAR. As I stated above all I wanted to share my libs which are POJO's I had to use following structure and my EAR was able to see classes successfully.
LIB1.ear
META-INF
application.xml
weblogic-application.xml
MANIFEST.MF
APP-INF
lib
*.jar (all pojo's here and WebLogic will add these into Application Classpath)
dummyejb-1.0.0.jar (just so that I can deploy this ear in server otherwise it won't continue)
