Inserting JSTL tags with plugin

I am building a graphical form creator where the user can add in a select list populated via a Java Bean.

I am running into a lot of problems when inserting the Html code. I have protected the JSTL tags with

config.protectedSource.push( /<c:set .*? \/>/g );
    config.protectedSource.push( /<c:forEach .*? \>/g );
    config.protectedSource.push( /<c:out .* \>/g );
    config.protectedSource.push( /<\/c:forEach>/g );

the following is the code in the plugin where I insertHtml

editor.insertHtml("<select name='tool'>"
                            +"<c:set var='toollist' value='${toolBean.tools}' />"
                            +"<option value=''>Select a tool</option>"
                            +"<c:forEach items='${toollist}' var='cur'>"
                            +"<c:out value='<option>${cur}</option>'/>"
                            +"</c:forEach>"
                            +"</select>");

I have tried using elements as well. The results are unsatisfactory as the tags will get filtered by CkEditor during the submit process. With the above, c:set tag is output correctly. "c;forEach" is not opened but closed. "c:out" is also truncated.

I have been searching around for an solution for 2 weeks.

Help is appreciated
