How to append "%" to a string in EL?

Question

I would like to construct a string with "%" in it in a <c:set> tag.

Here it goes:

<c:set var="test" value="${somethingA + '%' }" />

But this always give me a number format exception.

java.lang.NumberFormatException: For input string: "%"

So how do I work around this?

Answer 1

For those who wonder the same.

<c:set var="test" value="${somethingA }%" />

If there are more to come after the %, simply do

<c:set var="test" value="${somethingA }%${somethingElse }" />
