Well, you're right - I never declared that variable because I thought it should be available for every portlet. Isn't it possible to include a certain jar so that I can access "portletSession"? I've seen "portletSession" in various sample codes...
Here is my JSP: | <%@ taglib uri="http://java.sun.com/portlet"; prefix="portlet" %> | | <portlet:defineObjects/> | | <div align="center"> | <%! | java.util.Random random = new java.util.Random(); | int toGuess; | int guessedNumber; | long start; | long end; | long minuten; | long sekunden; | %> | <% | String value = renderRequest.getParameter("guessedNumber"); | | java.util.List <String> list = (java.util.List <String>)portletSession.getAttribute("bereitsGeraten"); | if (portletSession.getAttribute("toGuess")!=null){ | toGuess = (Integer) portletSession.getAttribute("toGuess"); | }else { | toGuess = random.nextInt(1000); | } | if (value != null){ | if (value.equals("neustart")){ | list = new java.util.ArrayList <String> (); | guessedNumber = -1; | toGuess = random.nextInt(1000); | } | else { | if (list == null){ | list = new java.util.ArrayList<String>(); | } | list.add(value); | try { | guessedNumber = Integer.parseInt(value); | }catch (Exception e){ | out.print("Fehler beim Lesen der eingegebenen Zahl!"); | } | } | } | | portletSession.setAttribute("bereitsGeraten",list); | portletSession.setAttribute("toGuess",toGuess); | %> | <form action="<portlet:actionURL><portlet:param name="page" value="mainview"/></portlet:actionURL>" method="POST"> | | <% if (guessedNumber == toGuess){ | end = new java.util.Date().getTime(); | minuten = (end-start)/(60*1000); | sekunden = ((end-start)%(60*1000))/ 1000; | %> | Super! Das war die gesuchte Zahl!!! <br> | Sie haben das Ergebnis in <%=minuten%> Minuten und <%=sekunden%> | Sekunden beim <%= list.size()%>. Versuch gefunden! <br> | <input type=hidden name=guessedNumber value="neustart"> | <input type=submit value=Neustart> | <% }else { | if ((value == null)||(value.equals("neustart"))) { | start = new java.util.Date().getTime();%> | Hallo! <br> Bitte eine Zahl zwischen 0 und 1000 erraten! | <% } else if (guessedNumber > toGuess) { %> | Die zu erratende Zahl ist kleiner! Noch ein Versuch: | <% } else if (guessedNumber < toGuess) { %> | Die zu erratende Zahl ist gröÃer! Noch ein Versuch: | <% } %> | <br> | <input type="text" name="guessedNumber"> | <input type="submit" value="raten"> | <br><br> | Bereits geratene Zahlen: <%=list %> | <%} %> | | </form> | </div> | It's a little game to guess a random number and it worked fine as a jsp-only application.
