I've only imported log4j.jar in my application. Are there some specific preliminary steps that I must do?
我只在我的应用程序中导入了 log4j.jar。是否有一些我必须执行的具体初步步骤？

I suspect that the clue is in the earlier error messages, which (according to Google) says "Error in JNDI name search" in Italian.
我怀疑线索在较早的错误消息中，它（根据 Google 的说法）用意大利语说“JNDI 名称搜索中的错误”。
In short, it would appear that your application is expecting to find the reference to database controller via JNDI, but that it is not there.
简而言之，您的应用程序似乎希望通过 JNDI 找到对数据库控制器的引用，但它并不存在。
By the way, the "error code: -2147467259" is probably just due to the application calling System.exit(-1).
顺便说一句，“错误代码：-2147467259”可能只是由于应用程序调用System.exit(-1).

See this, Java Reporting Component Deployment Guide, especially the section on setting up log4j.
Once you have read the doc you should be able to see error messages in more detail and then report them.
请参阅 Java Reporting Component Deployment Guide，尤其是有关设置 log4j 的部分。
阅读文档后，您应该能够更详细地查看错误消息，然后报告它们。
