Performance issue in JSP

[Naresh Talluri]

Hi All,

I had a small performance problem in my JSP , iam pulling thousands of values from DateBase, it is not taking much time but while constructing this data in JSP
it is taking much time, iam using struts tags to construct HTMl, in Tomcat 6.0,
Here is sample code ,

 <logic:equal value="<%=lResourceBundle.getString("messageform.formfield.statedropdown").trim()%>" name="lOptionData" property="optionTypeId">
	      <bean:define id="optionsDTO" name="lOptionData" type="com.acti.jms.objects.DTO.OptionsDTO" />
	        <logic:iterate id="states" name="lOptionData" type="com.acti.common.objects.LabelBean" property="stateList">
	           <%lXml += "<Value><Stepid>"+lMessageFormList.getStepId()+"</Stepid><OptionDataid>"+states.getValue()+"</OptionDataid><Jobid>"+lMessageFormList.getJobId()+"</Jobid><Instruction>"+states.getLabel()+"</Instruction><SpecifyRequired>null</SpecifyRequired><ParentStepId>"+lMessageFormList.getParentStep()+"</ParentStepId><OptionTypeId>"+null+"</OptionTypeId><Required>"+lMessageFormList.getTextBoxRequired()+"</Required><OutputOrder>"+lMessageFormList.getOutputOrder()+"</OutputOrder></Value>"; %>
	        </logic:iterate>    
	     </logic:equal>   

Here iam declaring one global variable as lXml to add data each and every iteration. i cannot avoid scriplet in this case , if we can how .?
I do have some more conditions like this in my JSP.
please suggest me how can i reduce load time of JSP..

Highly appriciated if you have any solutions

Thanks.

that is why,Paging(Pagination) Concept is introduced .

Exactly, but in my case it has to load the complete data,
can you please suggest..

why? you need to show all the datas in one page to the user? if yes what is the benefit ?

If this is the case. You can write some AJAX asynchronous calls to retrieve bunch of data from server. So that user can continue with data which is already loaded.

Does your user really need to see all this on the browser? Browser pages are so ephemeral - if they once look away, you have to regen the whole monster.

Consider creating a .pdf document in a separate Thread and giving a link to it when ready.
