我已在 xml 文件中创建了流程定义。 在此过程中，我有一个步骤应该将数据插入 mysql 数据库，但是当我运行代码时，出现以下错误:
Exception in thread "main" org.activiti.engine.ActivitiException: problem evaluating
script: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError:"ReportingUtil"is
not defined.(<Unknown source>#7) in <Unknown source> at line number

org.activiti.engine.impl.scripting.ScriptingEngines.evaluate(ScriptingEngines.java:89)
...
Caused by: javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError:

我从 java 类启动我的流程引擎。
这是我的流程定义:

我在这里读过关于需要使用绑定(bind)吗？ 有什么建议吗？
谢谢
最佳答案
importPackage(org.activiti.explorer.reporting.ReportUtil);
您正在尝试import一个类作为一个包。使用importClass。
我假设使用 Java 8 和 Nashorn。
