我已经尝试在C:\Users\MyUser\.p2\pool\plugins\org.mule.tooling.server.3.7.0_5.2.0.201508051354\mule\lib\user中添加jython-2.7.0.jar

在

C:\Users\MyUser\.p2\pool\plugins\org.mule.tooling.server.3.7.0_5.2.0.201508051354\mule\lib\opt

但没有结果。

我还尝试将 jython.jar 作为库添加到项目属性的 java build project 部分中。

我使用的是 Windows 10 和 jdk 1.8.0_66。

你能帮帮我吗？

谢谢

【问题讨论】：

我解决了删除带有扩展的eclipse并使用mule esb 3.8安装anypoint studio

标签： java python mule jython mule-studio

【解决方案1】：

Jython 应该是 Anypoint Studio 中运行时服务器的一部分。在 Package Explorer 和 Mule Server 3.7.0 库图标（书籍）中检查它。企业运行时应该有它，但如果你使用的是社区版，它就没有。

例如版本 3.7.2 EE 包含 jython-standalone-2.7.0 但它可能不像将这个 JAR 添加到库中那么容易。

第一个答案：社区版不支持您的需求。

第二个答案：尝试将 jython-standalone-2.7.0 添加到您的服务器库（运行时 ESB）而不是项目依赖项。

【讨论】：

嗨，大卫，感谢您的回答。服务器库的路径是什么？我已经在 C:\Users\MyUser\.p2\pool\plugins\org.mule.tooling.server.3.7.0_5.2.0.201508051354\mule\lib\user 和 C:\Users\ 中添加了 jython.jar MyUser\.p2\pool\plugins\org.mule.tooling.server.3.7.0_5.2.0.201508051354\mule\lib\opt 但它不起作用。
对于我的应用程序，它是 .classpath 文件中的 MULE_RUNTIME。这意味着它由 Anypoint Studio 设置和指定（路径）。尝试直接在 Eclipse 的 Java Build 区域中添加 JAR。让事情发挥作用，进行研究，然后将其移至真正应该去的地方。我不知道通过定制将社区版更新为企业版的最佳做法是什么。这是我书中的一个高级主题，我不相信您会在网上找到很多关于此的信息。尝试直接添加它，如果可行，请告诉我们。
