Q:

The entity "copy" was referenced, but not declared in jspx

I want to use copyright symbol in jspx, but it is not allowing me to use © . It is throwing me an error.
The entity "copy" was referenced, but not declared.
I googled it out and found that i need to modify escapeMode . But I do not know where I should change it.
Or anyone has the solution, please let me know.

A:

You may need to find the  section of your template and add the entity declaration.
Here's an example with a few common entities:
<!DOCTYPE html [
<!ENTITY nbsp "&#160;">  
<!ENTITY copy "&#169;"> 
<!ENTITY bull "&#8226;"> ]>

Here is a list of the entities in HTML4
