You can use the REST API to display a report. This page will help you get started, http://community.jaspersoft.com/wiki/jaspersoft-web-services-reference. Also, download the Web Services Guide from the Docs tab.

Thinking about your comment above where you say that when you lose the parameters when you click the refresh (reset) button, it makes sense because the server knows nothing about the parmeters sent in the URL and when you click on reset it just uses the default parameters. You will have to override the refresh button in your application to send the parameters again.  You can remove the refresh button from the tool bar  by editing /WEB-INF/jsp/modules/viewReport/ViewReport.jsp and comment out the following line:

                 <ul class="list buttonSet">

                <!--

                    <li class="leaf"><button id="dataRefreshButton" type="submit" title="<spring:message code="jasper.report.view.button.data.refresh" javaScriptEscape="true"/>" class="button capsule up"><span class="wrap"><span class="icon"></span></span></button></li>

                    -->

                </ul>

Using the HTTP API to display reports is much easier that using REST, so you may want to go that route.

 

Having said that, there is sample code at the bottom of the "Getting Started with the REST Web Service API" page. You'll have to download and install Maven to run it but otherwise it's pretty straight forward. You can also find sample client code in the samples folder in the distribution.
