"Portlet is temporarily unavailable" error in liferay 6.0.6 tomcat

[fatima zohra, modificado hace 11 años.]

I'm using Liferay 6.0.6 tomcat. I'm developping a liferay mvc portlet to display a form. But I get the message "Portlet is temporarily unavailable". I can't figure out what the problem is.

While adding the portlet to the portal I get these errors:

There's a problem in your jsp page causing an infinite loop.

You may be missing an import. If you're using Liferay IDE, check if there aren't any errors being tagged.
