BeanAlreadyExistsException - Oracle WebLogic

BeanAlreadyExistsException - Oracle WebLogic

提问by JonH

I deployed an app on my web server and now I am trying to deply another one on the web server and I am getting a BeanAlreadyExistsException. I thought it might be due to the fact that I have two beans with the same name in the two different projects. So I removed the first project from the server - however that didn't work - I still ended up getting this exception when deploying the second app.

我在我的网络服务器上部署了一个应用程序，现在我试图在网络服务器上部署另一个应用程序，但我收到了一个 BeanAlreadyExistsException。我想可能是因为我在两个不同的项目中有两个同名的 bean。所以我从服务器中删除了第一个项目——但是那没有用——我在部署第二个应用程序时仍然得到了这个异常。

Here is the stack trace:

这是堆栈跟踪：

You may try getting rid of "app-deployment" section from the /base_domain/config/config.xml, which contains the ear/war **

您可以尝试从 /base_domain/config/config.xml 中删除“ app-deployment”部分，其中包含 ear/war **

**

回答by Oleg Kaploun

Open youu weblogic.xmlfile .And see the library-reftags . Most probably there is a duplication reference to the webapp.encoding.default( this is library that mentioned in your log )

打开您的 weblogic.xml文件。并查看 library-ref标记。很可能存在对webapp.encoding.default的重复引用 （这是您日志中提到的库）

回答by NITIN

simply remove multiple library reference from weblogic-application.xml file .

只需从 weblogic-application.xml 文件中删除多个库引用。

1. cd $DOMAIN_HOME
2. cd config/jdbc
3. Delete to xml file of config
4. Restart server

1. cd $DOMAIN_HOME
2. cd config/jdbc
3. 删除到配置的xml文件
4. 重启服务器
