can you upload your code here and we try to reproduce it .
It seems that there are some problems in your classpath.

[7年前 に Simone Olita によって更新されました。]

what do you exactly mean with code?

if you mean source code is exactly the same that you posted in this tutorial :
https://dev.liferay.com/develop/tutorials/-/knowledge_base/6-2/writing-your-first-liferay-application

if you mean any other code, would be glad if you would me more specific

thanks
