“我如何解决？”；“未定义包”；在具有应用服务器功能的WSO2 Carbon 4.0.3中？

我正在尝试从WSO2 Carbon 3.0.0升级到Carbon 4.0.3。使用Carbon 3.0.0，在安装了必要的功能之后，我能够编写JavaScript Mashup服务来调用外部Java库——而且由于WSO2 Carbon使用Rhino，我能够使用importPackage。我在Carbon 4.0.3上无法获得相同的功能

我遵循的程序是：

下载并解压缩WSO2 Carbon 4.0.3

起始碳

导航到“功能管理”页面

添加4.0.3碳p2存储库（）

搜索并安装“应用程序服务器”功能

重新启动碳

部署我的测试Mashup服务

使用“tryit”工具执行我的测试Mashup服务的echo操作

我的测试Mashup服务（TestMashup.js）：

如何修复此问题，以便继续使用JavaScript Mashup服务中的Java库？

当您将所需功能安装到Carbon server时，请查看控制台中是否打印出任何错误。可能存在一些依赖性问题。安装这些功能后，使用命令

/wso2server.sh-DosgiConsole

启动WSO2，并使用

ss

命令和

comp

命令查看是否存在任何未解决的OSGi依赖项。如果有，请尝试将所需的捆绑包放入存储库/组件/dropins并重新启动服务器

而且我也不确定是否只有安装ApplicationServer功能才能满足您的Mashup需求。因此，在该存储库中，可以查看是否有任何与Mashup服务器相关的功能可用。如果是这样，也安装它们。似乎在您的服务器、主机对象“包”中存在一些问题

---

当由于依赖性问题而无法安装某些功能时，可以尝试将所需的捆绑包放入dropins目录。如果同样失败，您可能必须签出与该组件相关的代码，并将其向后移植到您的服务器版本。

允许此功能工作的代码已被禁用

我花了一些时间查看carbon SVN存储库，发现

消息接收器

mashup组件的修改方式阻止了使用

ImporterTopLevel

上下文创建JavaScript mashup服务。这可以在

org.wso2.carbon.mashup.javascript.messagereceiver.JavaScriptEngine

中直接看到，其中以前的版本扩展了

ImporterTopLevel

，但新版本没有扩展。为便于将来参考，此更改是根据129254版提交的

---

我已经能够将3.2.2中的

ImporterTopLevel

代码合并到

messagereceiver

的4.0.3版本中，以解决此问题。

SS显示所有已安装、活动或已解决的模块。我在找什么特别的东西吗？我实际上没有看到任何可以识别“Mashup服务器”的特性；据我所知，Mashup服务器内置于应用服务器中。我应该安装什么来获得此功能？有关OSGi命令，请参阅web中的OSGi文档。使用diag[id\u show\u in\u ss\u command]您可以探索ss命令中显示的每个项目是否存在任何问题。若并没有类似于Mashup服务器的特性，那个么看看是否有任何特性的名称类似于主机对象。只有在Mashup服务器被放弃之后，AFAIK Mashup服务器才会与applicationserver打包。之前有一个单独的服务器，名为mashupserver.Maninda-您至少可以确认它对您有效吗？还是应该仍然有效？？？它不起作用-见上面Josh的评论。为了支持Jaggery/Rhino引擎而不是纯Rhino，ws02打破了将jar文件或本机java导入JS服务引擎的能力。当你们称自己为企业引擎时，破坏事物是不好的。

this.serviceName = "TestMashup";

echo.inputTypes = "#raw";

    return new XML(response);
}
