Question

我在Java中构建了一些库控件来扩展一些（JSF）控件，如Edit Box，Combobox等。我想在JAR文件中打包我的控件（只有java代码），但每次我用jar替换java文件时都会出错。

有人知道我为什么会收到此错误吗？我无法创建插件，因为扩展控件只能在一个NSF中使用。

错误500
HTTP Web服务器：命令未处理异常

以下是日志文件中的完整错误：

Answer 1

我认为你在某个地方有一个空值

引起：java.lang.NullPointerException at java.lang.Class.isAssignableFrom（Native Method）在com.ibm.jscript.types.JavaAccessObject $ ClassInfoCache。（JavaAccessObject.java:1050）

可能在SSJS语句中或在SSJS调用的java类中

引起：com.ibm.xsp.exception.EvaluationExceptionEx：执行JavaScript计算表达式时出错在com.ibm.xsp.binding.javascript。 JavaScriptValueBinding.getValue（JavaScriptValueBinding.java:132）在com.ibm.xsp.model.domino.DominoDocumentData.getComputeWithForm（DominoDocumentData.java:206）

至于将java源导出到jar文件。我假设你在日食工作。右键单击您想要导出的eclipse中的插件并选择“Export”，然后在出现的对话框中选择“Plug-in Development \ Deployable Plug-ins and Fragments”。在下一个对话框中，选择要将插件导出到的路径（可能是％Domino_Program％\ data \ domino \ workspace \ applications \ eclipse文件夹）。然后执行“重启任务http”（您必须使用它，因为它也重新启动JVM）并且您的插件应该可供服务器使用。

由于您还在开发组件，我假设您希望设计器中提供这些组件。由于我不确定您是如何设置设计器的（即通过更新站点安装或通过插件插入的链接目录），我将需要更多信息。如果您使用的是更新站点，请使用google查找如何从eclipse构建更新站点。
