What is the difference between Liferay PortalEnterprise and Liferay Portal Professional? The Enterprise version of Liferay portal uses Session EJBs to provide heavy scaling and transaction support required by large sites. This version requires an application server such as JBoss or Orion. The professional release of the portal calls java objects directly to provide a light weight facade. This version can be used with a servlet container like Tomcat. However, the source between the two is the essentially the same. A property, "portal.release", within a properties file distinguishes between which is being used.
In most instances, you should use Liferay Portal professional unless you require distributed transactions.
What do I do if I am getting Out of Memory Errors? Out of memory errors can occur for a variety of reasons. One suggestion is to increase the amount of memory in your startup options for your application server/container.
How do I customize the General Guest pages? Log into the portal with as a privileged user to change General Guest layouts. Switch to the General Guest comunity. Configure the page.
