如何使用Application Server功能解决WSO2 Carbon 4.0.3中的“未定义包”？-Java 学习之路

我正在尝试从WSO2 Carbon 3.0.0升级到Carbon 4.0.3 . 使用Carbon 3.0.0，在安装必要的功能之后，我能够编写可以调用外部Java库的JavaScript Mashup服务 - 而且由于WSO2 carbon使用Rhino，我可以使用importPackage . 我无法在Carbon 4.0.3上获得相同的功能 .

我遵循的程序是：

下载并解压缩WSO2 Carbon 4.0.3
开始碳
导航到"Feature Management"页面
添加4.0.3 Carbon p2存储库（http://dist.wso2.org/p2/carbon/releases/4.0.3/）
搜索并安装"Application Server"功能
重启碳
部署我的测试Mashup服务
使用"tryit"工具执行测试Mashup服务的echo操作 .

我的测试Mashup服务（TestMashup.js）：

this.serviceName = "TestMashup";

echo.inputTypes = "#raw";
echo.outputType = "#raw";
function echo(parameter) {
    var javaDate = new Packages.java.util.Date();
    var response = "<echo><value>" + parameter.toXMLString() + "</value><timestamp>" + javaDate.getTime() + "</timestamp></echo>";

    return new XML(response);
}

我已将此Mashup服务安装到CARBON_HOME / repository / deployment / server / jsservices / admin /

当我在Carbon 3.0.0上运行此操作时，我得到以下响应：

<echo>
  <value>
    <r>test</r>
  </value>
  <timestamp>1360699125311</timestamp>
</echo>

当我尝试在Carbon 4.0.3上运行此操作时，我得到以下堆栈跟踪：

如何解决这个问题，以便我可以继续使用JavaScript Mashup服务中的Java库？

允许此功能工作的代码已被禁用 .

我花了一些时间浏览carbon SVN存储库，发现 message-receiver mashup组件的修改方式可以防止使用 ImporterTopLevel context创建JavaScript Mashup服务 . 这在 org.wso2.carbon.mashup.javascript.messagereceiver.JavaScriptEngine 中直接可见，其中先前版本扩展 ImporterTopLevel 但较新版本不扩展 . 为了将来参考，此更改是针对修订版129254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版本中以解决该问题 .

在Carbon服务器上安装所需功能时，请查看控制台中是否打印了任何错误 . 可能存在一些依赖性问题 . 安装功能后，使用命令 ./wso2server.sh -DosgiConsole 启动WSO2 AS并使用 ss 命令和 comp 命令查看是否存在任何未解析的OSGi依赖项 . 如果有，请尝试将所需的包放入repository / components / dropins并重新启动服务器 .

此外，我不确定是否只安装Application Server功能将启用您的Mashup要求 . 因此，在该存储库中，查看是否有可用的Mashup Server相关功能 . 如果是这样安装它们 . 在您的服务器中，主机对象“Packages”似乎有一些问题 .

如果由于依赖性问题而无法安装某些功能，则可以尝试在dropins目录中放置必需的bundle . 如果这也失败了，您可能需要签出与该组件相关的代码并将其反向移植到您的服务器版本 .
