Description

We recently upgraded from Struts 2.1(don't ask) to Struts 2.5.13 , while the upgrade process was smooth, we are facing some performance issue while JSP is rendering at runtime. This JSP used to load in less then 2 secs before and now it's taking around 40 secs to load. It's a very simple JSP with some text fields and a few select fields. I am just posting a simple select that is taking around 20 secs, I cannot post the whole code because of obvious reasons. The time difference between the two-time statements below is around 20 secs.

I have tried to remove styles, javascript function but still it's taking a long time. Any suggestions in this regard will be helpful. This is happening most of the select boxes.

System.out.println("logging started");
java.util.Date date49 = new java.util.Date();
%>
The time is now <%= date49 %>
                            <s:select cssClass="textBox_normal" cssStyle="width:100%; height:100%" name="showDoc" id="showDoc" multiple="true" size="5" 
	       						  headerKey="-1" 
	       						  list="doclist"
	       						  listKey="id"
	       						  listValue="Description"
	       						  onchange="disableErrormsg('VarLibAssetErrorDiv');"
	       						  />
	                </div>
                    <div style="float:left; width:20%; height:100%; display: none" id="documentTypeDiv">
                    	<%
	System.out.println("logging started");
java.util.Date date5 = new java.util.Date();
%>
The time is now <%= date5 %>
