两个服务不能具有相同的名称。系统中已存在具有wso2carbon sts[null]名称的服务

我正在尝试在wso2esb 4.8.1上安装API Manager 1.6.0。我已在此上安装了所选功能，在尝试重新启动时，出现以下异常

`[2014-03-25 09:16:52,021] ERROR {org.wso2.carbon.utils.deployment.Axis2ServiceRegistry} -  Error building service from bundle : Symbolic Name: org.wso2.carbon.sts,Bundle Version: 4.2.0, ID: 545

谁能帮我一下吗

我想同时使用API管理器和wso2 esb特性。那么，实现这一点的最佳实践是什么呢？是否可以在wso2 carbon中安装这两个组件

---

我已经尝试了很多，没有从任何地方得到正确的响应，，，请在这方面帮助我。

建议分别运行WSO2ESB和API Manager

---

是的，可以在WSO2 Carbon中安装这两个组件

ESB中介引擎已经是API管理器的一部分。例如，通过将相关的代理服务工件复制到文件系统中，您应该能够在API manager中部署代理服务，而不会出现任何问题。 您能解释一下AM需要使用什么类型的ESB功能吗？是否要使用代理服务/序列编辑器UI

谢谢

谢谢你的回复。。但在wso2carbon中安装这两个组件时，我面临着这个问题。。如何在wso2carbon中安装这两个。你能帮我吗，请，，，我想同时使用这两个方法在carbon中安装这两个。我使用的是wso2carbon 4.2.0，哪一个需要安装第一个ESB或API管理器，因为我是wso2的新手，你能在这个PLS上帮助我吗？如果你尝试功能安装UI。功能已分组。请尝试以下链接：感谢您的回复，，我想在wso2 carbon上安装fresh ESB（所有功能），还需要安装API manager。。有可能这样做吗，，，
