打开宾得数据集成中任何Kettle转换文件时出错

Question

我使用PDI已经很长时间了，在打开以前正常工作的同一个文件时，现在打开后立即显示以下错误：

java.lang.NullPointerException

同一文件在另一台机器中完全打开，并且运行良好。在Spoon调试日志中，我得到以下错误：

我试着卸载和重新安装PDI，但它没有工作。还尝试过清除pentaho_data_integration_dir\data-integration\system\karaf\caches.中的缓存。

编辑:在数据集成中保存新创建的转换/作业时也会出现此错误。

请帮帮忙。谢谢。

Answer 1

啊..。这很难检查，但如果我在你的地方会检查下面的

difference.

• check

1. 所有必需的组件都可以在您打开文件的勺子中使用。
2. 右键单击并比较xml版本的文件，以发现正在运行的java_home设置和java_home服务。
3. 删除该文件并将其替换为备份文件。
4. 将该文件放置在另一个文件夹中，然后尝试打开它。操作accordingly.

可能会出现更多的描述性错误。
