Show HTML in JSP (don't “render” HTML)

Question

I have a JSP page that accepts SQL queries, executes them, and then returns the results in a table. Some of the results sometimes have HTML tags in them, i.e. the result is returned:

This is the returned result! I have <br> and <hr> tags!

When it is transmitted through the code to process the return and puts it into the table, he actually "displays" tag <br>and <hr>as HTML, but I want him to just display the actual <br>and <hr>.

Returns are currently being printed using <% = colvalue%>

How can i do this?

You can use the JSTL tag. It has an escapeXML parameter that will do what you want to do.

In PHP you would use htmlentities and htmlspecialchars
