Question: How to print out html markup with h:outputText?

Answer: The h:outputText has attribute escape that allows to escape the html markup. By default, it equals to "true". It means all the special symbols will be replaced with '&' codes. If you set it to "false", the text will be printed out without ecsaping.

For example, <h:outputText value="<b>This is a text</b>"/>

will be printed out like:

<b>This is a text</b>

In case of <h:outputText escape="false" value="<b>This is a text</b>"/>

you will get:

This is a text
