The user can click on a hexagon to get more information about it (need a trip to the server), and they can also move units from one hexagon to another). Pretty standard stuff, but I want to implement it thin_as_I_can client, and I want to use JSF. I suppose this would be a custom component. Probably an applet would be the easiest way to implement the map, but is there anyway to nicely integrate an applet into the JSF framework, perhaps as a JSF component? ============================================================================== TOPIC: Where to find api of XPath?@@. http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/bc5ec4ab4aef4964 ============================================================================== == 1 of 1 == Date: Tues, Dec 14 2004 9:47 pm From: [EMAIL PROTECTED] (mikeotp) regards: Where to find api of XPath?@@. thank you May god be with you ============================================================================== TOPIC: java socket vs tcp stack parameters in XP http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/0a9d0e05981fa88a ============================================================================== == 1 of 2 == Date: Tues, Dec 14 2004 10:01 pm From: "antoine" Hello, I'm running a java application on my XP Pro box that should send messages to a server. I use a regular java socket, and all is fine on this side. all messages are sent and received with no problem. however, when I analyze the traffic with a sniffer, I can see that, for example, when sending 3 messages in a row (writing 3 the 3 messages on the socket, but with very little interval time < 1ms), then: - the FIRST message is sent immediatly on the wire - the SECOND and THIRD messages are sent TOGETHER, but roughly 100ms AFTER the first one. it looks like the box is waiting for some kind of TCP ACK or heartbeat before sending the second and third messages. I've looked into ways of improving this, and read a few things about TCP/IP stack tuning on solaris (tcp_naglim_def), but have found very little info about XP tcp stack tuning apart from modifying the window size. would anybody know of a good reference to find a solution to this problem ? would you know which tcp parameters are tunable on XP, and how ? what are tcp_deferred_ack_interval ? tcp_nodelay ? any help would be greatly appreciated... thanks !

I am facing a problem in Macintosh. Currently we are testing Oracle based Forms Application using Oracle 9i which is entirely based on Applets. For invoking that application, we will be given an URL, which invokes the instance for starting the oracle, basically being an Oracle 9i Web Services Application, initally the IE loads the Applet screen followed by the application. We need to test it in Safari, Netscape and IE. For Safari and Netscape, we downloaded the MRJ 2.2.5 and installed the Applet Run Time Java (MRJ). The applicaiton is running smoothly in Netscape and Safari. Where as in case of IE, the applet is not recognized while loading the application. I dont know the exact reason. I think it may be the problem of IE, bcoz in preferences settings there is no inclusion of MRJ in Java tab. But we enabled all the predefined settings like "Alert" and so on... Till we are yet into the problem, so thats why i need your suggestion in order to solve the problem. In case of MAc 9.2 we are testing the application using IE 5.1, in that whenever we type the URL in the browser, the status bar says that "Applet-Instance Started".... "Contacting the Server..." and finally it says..."Applet - Error - Closing...". Also the application is not viewing in the browser. Awaiting for your solution...

I want to load a form and submit it. Then I want to go to one of several pages (which are also part of the form). In the form I have some data that needs to be loaded in selects and multiple checkboxes. To do this, it seems I should use beans. First question, how do I define this in the struts-config.xml? I'm using tiles, so in the tiles-config it looks like this: <definition name=".testForm" extends=".main.layout"> <put name="left" value="/pages/left.jsp" /> <put name="body" value="/pages/test.jsp" /> </definition> In the struts-config.xml: <forward name="testForm" path="/testForm.do"/> ... <action path="/testForm" forward=".testForm"/> Where do I add the beans I need. And where do I load the data into them? If I add an action type, how do I forward it? <action path="/testForm" type="test.TestAction" forward=".testForm"/> In the test action class I can load the data into beans, I suppose; public ActionForward execute( ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { HashMap items = getItems(); //request.setAttribute("items", items); //servlet.getServletContext().setAttribute("items", items); HttpSession session = request.getSession(); session.setAttribute("items", items); return mapping.findForward("testForm"); } I could connect to the database and populate a HashMap in the getItems method. But what about the findForward? Doesn't that lead back to the very same action - like an iternal loop? If so, do I need to create a new action, that forwards to this one? <action path="/testForm" type="test.TestAction" forward=".testForm"/> .. <action path="/testForm2" forward=".testForm2"/> .. return mapping.findForward("testForm2"); I guess there is no use to continue before I got these things sorted out.
