Why do I get Nullpointer exception when I create a hibernate mapping XML file?

Question

I am a newbie to hibernate and trying to create a hibernate XML mapping file for a particular class. I am using Spring Tool Suite with hibernate plugin installed and also using Maven. Why do I get the null pointer exception and what could be the reason for it? A screenshot is also attached

It says see error log. But I do not know where the error log exists. I tried a google search too, but could not find a good answer. Any kind of help will be highly appreciated. Thank You all !!!!!!

Answer 1

I could solve this problem by using a different version. As said by one of my friends I think the problem was with the version that I was using. Then I tried it with Eclipse Kepler and the problem was gone :)

设置休眠配置就可以了，有一个名为“休眠配置”的选项卡，您可以在其中添加项目，然后在其中进行一些配置。
