If I'm not mistaken you are referring to Liferay, it seems like a CMS focused on ecommerce or business?
If that is that case, you can embed your form using different methods found in our "Embed Form" options here:
You can also use the form's full source code, here's how you can get it: http://www.jotform.com/help/104-How-to-get-the-Full-Source-Code-of-your-Form.
If you are familiar with API and directly fetch data and use it in your Liferay powered system, then you can check our API documentation here: http://api.jotform.com/docs/.
Do let us know if that works
