Need to retain the drop down value after submitting the form

I have a jsp page which contain drop downs and two buttons. One button for Upload and other is Run button. I want to retain the value of drop downs even after the Upload is clicked and submitted the form so that the same values should pass for Run button . I used the below code.

<select name="riskType" class="filter_smalltext" onchange="regAuthChange();">
                                          
                                          <option value="" selected="selected">Choose One</option>
                                          <option value="<%if(request.getParameter("riskType").equals("CR")) {out.println('selected="selected"'); } %>">CR</option>
                                          <option value="<%if(request.getParameter("riskType").equals("MR")) {out.println('selected="selected"'); } %>">MR</option>
                                          <option value="<%if(request.getParameter("riskType").equals("BOTH")) {out.println('selected="selected"'); } %>">BOTH</option>
                              </select></td>

But i am getting this error :
jv_allocation_process.jsp:16:18: Error in "jv_allocation_process.jsp" at line 401: Invalid character constant
<%@ include file="templates/jv_allocation_process.jsp" %>

Probably you have double quotes inside the string. Escape them first and then retry to run the code.

Just look close in what HTML you get with this:

<option value="<%if(request.getParameter("riskType").equals("CR")) {out.println('selected="selected"'); } %>">CR</option>
<option value="<%if(request.getParameter("riskType").equals("MR")) {out.println('selected="selected"'); } %>">MR</option>
<option value="<%if(request.getParameter("riskType").equals("BOTH")) {out.println('selected="selected"'); } %>">BOTH</option>

You get wrong HTML with unclosed quote. You have to do:

<option value="CR" <%if(request.getParameter("riskType").equals("CR")) {out.println('selected="selected"'); } %>">CR</option>
<option value="MR" <%if(request.getParameter("riskType").equals("MR")) {out.println('selected="selected"'); } %>">MR</option>
<option value="BOTH" <%if(request.getParameter("riskType").equals("BOTH")) {out.println('selected="selected"'); } %>">BOTH</option>
