Embedding Web-Content in custom Portlet

[Mario Starlinger，修改在6 年前。]

Hello everybody,

i want to embed a web-content in my custom portlet. But I can't find a suitable solution. In Liferay 6.2 there was a taglib.
What is the best way to embed a web-content in a custom-portlet in .in JSP in Liferay 7?

Thanks in advance!
