Instead of recreating the app context class every time why not just
create one and add some setters for result, motor and customer? Then in
the getAppContext method re-query for the results. If you do this
approach I assume your app context class will be static.
Another approach is the pass the result, motor and customer to the
report as url parameters and let the report create the reportData
object. You do this using the EMITTER_OPTIONS key:
HashMap myparms = new HashMap();
HashMap emitmap = new HashMap();
myparms.put("SERVLET_NAME_KEY", "frameset");
myparms.put("FORMAT_KEY", "html");
//myparms.put("RESOURCE_FOLDER_KEY", "c:/myresources");
myparms.put("ALLOW_PAGE", "false");
myparms.put("SHOW_PARAMETER_PAGE", "false");
emitmap.put("myurlparameter", "this is a test");
myparms.put("EMITTER_OPTIONS_KEY", emitmap);
WebViewer.display(rpt, browser, myparms);
In script you can then retrieve the url parameter like:
reportContext.getHttpServletRequest().getParameter("myurlparameter");

In the getAppContext, instead of adding my parameters to the Map passed in, I created a new one. As soon as I added my parameters to the one passed in, everything started working correctly.
