I am trying WSO2 API Manager 2.0 and failed to start the server. Would you like give a hand? Thanks a lot Michael
以下是版本信息.
[wso2@srv11 bin]$ ./wso2server.sh --version
WSO2 API Manager v2.0.0
WSO2 Carbon Framework v4.4.7
但是当我使用wso2server.sh --start"命令启动API Manager时，我在wso2carbon.log中发现了以下错误信息.
But when I start the API Manager with "wso2server.sh --start" command, I found following error information in wso2carbon.log.

推荐答案
出现此警告可能是由于 Java 首选项子系统无法写入目录/etc/.java/.systemPrefs.您能否验证您的系统中是否存在/etc/.java/.systemPrefs 目录?如果存在，它对运行 JVM 实例的用户是否可写?如果没有，请提供权限并重新启动 APIM.
This warning could occur due to Java Preferences subsystem not being able to write to the directory /etc/.java/.systemPrefs. Can you verify that the the directory /etc/.java/.systemPrefs exist in your system? If it exists, is it writable for the user running the JVM instance? If not please provide permission and restart APIM.
如果上述方法不起作用，您也可以尝试以下解决方法.
If the above does not work you can also try the below workaround.
1) 在运行 JVM 的用户可以访问的地方创建一个目录，并具有以下子结构./.java/.systemPrefs
1) Create a directory in a place accessible to the user running the JVM and have the following substructure. /.java/.systemPrefs
2) 使用 Java 选项 -Djava.util.prefs.systemRoot=
2) Start WSO2 APIM server with the Java option -Djava.util.prefs.systemRoot=<CREATED_DIR>/.java
