Glassfish 4 deployment error
提问by galovics
I added some libraries to my JavaEE project and then deploy the application works. I modified something and I got this error message in Eclipse:
我在我的 JavaEE 项目中添加了一些库，然后部署应用程序工作。我修改了一些东西，我在 Eclipse 中收到了这个错误消息：
Cannot Deploy ProjectName
deploy is failing=Error occurred during deployment: Keys cannot be duplicate.
Old value of this key property, nullwill be retained.
Please see server.log for more details.
java.lang.LinkageError: loader (instance of
org/glassfish/web/loader/WebappClassLoader):
attempted duplicate class definition for name:
"org/glassfish/web/loader/JdbcLeakPrevention"
loader (instance of org/glassfish/web/loader/WebappClassLoader): attempted duplicate
class definition for name: "org/glassfish/web/loader/JdbcLeakPrevention"
I made some research and I found out that it is not an Eclipse bug. I'm working with Kepler but I tested with Juno too. Got the same error message. I downloaded Glassfish 3.1.2.2 and the message gone.
我做了一些研究，发现它不是 Eclipse 错误。我正在使用 Kepler，但我也使用 Juno 进行了测试。得到同样的错误信息。我下载了 Glassfish 3.1.2.2 并且消息消失了。
Why am I getting this message?
为什么我会收到这条消息？

Try to clean autodeploy directory, restart the server. Also clean the project deployment directory.
尝试清理 autodeploy 目录，重新启动服务器。还要清理项目部署目录。

I also had this issue, and I was also using the SVNKit library plus its dependencies so it looks like there is some kind of conflict there. I can get around it by cleaning out the osgi-cache folder & restarting glassfish, but I have to do this every time I want to deploy, so not a great solution.
我也遇到了这个问题，而且我还使用了 SVNKit 库及其依赖项，因此看起来那里存在某种冲突。我可以通过清除 osgi-cache 文件夹并重新启动 glassfish 来解决它，但是每次我想部署时都必须这样做，所以不是一个很好的解决方案。

I Had the same error. I stopped the GLassfish server and then I cleaned the project (Project -> Clean... ). Started the server and worked
我有同样的错误。我停止了 GLassfish 服务器，然后我清理了项目（项目 -> 清理...）。启动服务器并工作

Was somehow related to a single @Singletonbean. Converted it to @Statelessand everything worked fine. Not quite sure why this happened...
不知何故与单个@Singleton豆有关。将其转换为@Stateless，一切正常。不太清楚为什么会这样......

In my Glassfish logfile it says:
在我的Glassfish 日志文件中，它说：
Application with name ws is already registered. Either specify that redeployment must be forced, or redeploy the application. Or if this is a new deployment, pick a different name
名称为 ws 的应用程序已经注册。要么指定必须强制重新部署，要么重新部署应用程序。或者，如果这是新部署，请选择其他名称
Following my logs instructions I deployed the app with --forceoption:
按照我的日志说明，我使用以下--force选项部署了应用程序：
asadmin deploy --force=true ws.war
and it worked. More info on deploy --force=true
它奏效了。有关deploy --force=true 的更多信息

Try to remove all the files under osgi-cache and generated directories. It worked for me.
尝试删除 osgi-cache 和生成目录下的所有文件。它对我有用。

following steps worked for me.
以下步骤对我有用。
- stop the glassfish server(if running)
- kill all the java process (using terminal or activity monitor)
- now try redeploy.
- 停止 glassfish 服务器（如果正在运行）
- 杀死所有 java 进程（使用终端或活动监视器）
- 现在尝试重新部署。
