    Partial JSP render issue

    Jasim Jamal Newbie

      We’ve recently migrated our application from Weblogic to JBoss EAP 6.4 and facing one issue of partial JSP render.

       

      Brief Overview of the Application Flow: In "Reports and Analysis(name of the application)" we have several Tabs from where we select the criteria and generate Reports. On submission reports are queued and processed sequentially. After the report is processed it is displayed in HTML,XLS,PDF and CSV format using jasper templates.

       

      Issue: XLS, CSV and PDF reports  are getting generated successfully with complete display of data but HTML format has some aberrations. It is not getting rendered as expected . Report content appears fine but other included JSP’s in ReportsResults.JSP fail to render successfully.. Please refer below images for more clarity.

       

      JBoss version of Report (display as expected)

      Weblogic version of Report (display as expected)

      Resolutions we already tried :

      ·    Increased JSP page Buffer.

      ·    Incorporated trimDirectiveWhitespaces="true"

      ·    Changed the page encoding from ISO -8859 to UTF-8 <Earlier, nothing was being displayed after this change atleast report content is getting displayed>

      ·    Used “Include” directive as well but didn’t work.

      ·    Modfied JSP configuration of Jboss to set trimDirectiveWhitespaces="true".

       

      This page displayed above is ReportsResults.jsp which further contains some includes and below mentioned

      scriplet code that prints the output data inside a section.

       

      But included jsp's are not appearing as an outcome only HTML_OUTPUT content is getting displayed.

       

      Below is the scriplet code that prints the HTML output:

       

      <%String data = (String) request.getAttribute("HTML_OUTPUT");

      response.setContentType("text/html");

      PrintWriter outWriter = new PrintWriter(response.getOutputStream());

      outWriter.print(data);

      outWriter.flush();

      outWriter.close();

      %>

      <% out.clear();out = pageContext.pushBody();%>

       

       

      For reference, I’ve attached the jsp files too. Please let us know if you need further detail.

      Appreciate if you can lend a helping hand in solving this problem.
