Escape <%%> In jsp

I have a field helper jsp file which churns out code for various components. The field helper jsp returns a string which is used by another jsp, which shall be called foo. I need to have the scriplet tags in foo in order to call the URLEncoder encode method. Unfortunately, the field helper jsp is causing errors due to the <% %> in htmlString. Is there any way to escape the <% %> tags in a jsp?

Tech: struts 1.3 & jdk 1.7 excerpt of field helper jsp

<% 
//do stuff here
htmlString.append("<TD> <A HREF=\"fileDownload.jsp?filename=<%=URLEncoder.encode("+example+")%>\" TARGET=\"_BLANK\"> "+foo+" </A></TD>");
return htmlString;%>

I have already tried the following escapes: 

\<% %\n 
<\% \%>
\<\% \%\>

There isn't any need to do so, you can call URLEncoder.encode(String) directly. Something like

htmlString.append("<TD> <A HREF=\"fileDownload.jsp?filename=" 
        + URLEncoder.encode(example) + "\" TARGET=\"_BLANK\">" 
        + foo + " </A></TD>");
