Liferay on GlassFish: deployment fails

Could anybody give a short-list what to do when deployment to Liferay (with Glassfish) fails? For me it is taking extensively time for getting to know new ways tha开发者_如何学运维t the process can fail.

If you deploy a portlet to Glassfish and then try to see it in Liferay and you DO NOT see anything, check:
- Is the deploy failed?
- Is there a restart made before you go to see results?
- Does the server give you any errors on log?
- If deployment does not work one way, try another. You can use Liferay menu Plugins Installation-> Upload File or try the method on this post
