  • Jetty 6 to Jetty 7 upgrade: what happened to system property "jetty.lib"? (-Djetty.lib=my/lib/dir)

    - by StaxMan
    Looks like Jetty team wanted to do some spring cleaning between versions 6 and 7, and it looks as if one useful system property, "jetty.lib" either does not exist, does not work, or just has changed in an unspecified way so as to make my jetty 6 set up work easily with Jetty 7. I tried searching through Jetty 7 docs, but about the only reference I saw was that "some commonly used properties (such as "jetty.home") still work as they used to". So, what am I missing? I really would want to avoid messing with things within Jetty distribution dirs (otherwise I could -- and maybe I have to? -- just use JETTY_BASE/lib/ext), and that's what "jetty.lib" was useful for.

  • Unable to connect on socket across different networks.

    - by maleki
    I am having trouble connecting my online application to others across another network. I am able to give them the hostAddress to connect when we are on the same network but when we are doing it across the internet the generated host address doesn't allow a connection, nor does using the ip address gotten from online sites such as whatismyip.com My biggest issue isn't debugging this code, because it works over intra-network but The server doesn't see attempts when we try to move to different networks. Also, the test ip I am using is 2222. InetAddress addr = InetAddress.getLocalHost(); String hostname = addr.getHostName(); System.out.println("Hostname: " + hostname); System.out.println("IP: " + addr.getHostAddress()); I display the host to the server when it is starting if (isClient) { System.out.println("Client Starting.."); clientSocket = new Socket(host, port_number); } else { System.out.println("Server Starting.."); echoServer = new ServerSocket(port_number); clientSocket = echoServer.accept(); System.out.println("Warning, Incoming Game.."); }

  • "org.json.JSONArray implements Serializable": What's the best option to achieve this?

    - by Daxon
    I am using Grails Webflow, what ever object I pass to a view, it must be Serialized. My domain models "implement Serializable", so they work. The problem is when I get a response from a WebService. It is of the org.json.JSONArray class. I just want to pass the whole Array over to the view yet it doesn't implement Serializable, so it fails, Any thoughts on how I can pass this, or my best option? Can I just edit the source of the org.json library and make every class "imp Serializable"? Or process the result into Domain objects that do "imp Serializable"

  • how to reuse the area in a container when any component is removed from it?

    - by vybhav
    hi! i hav a panel and i m trying to remove labels from it which were added to it during run-time. but when labels are removed succesfully i m not able to use the space,left by that label,again to add any label to it. thanks in anticipation of the solution. here is the relevant code snippet: to add label to the panel: JLabel jl = new JLabel(); jl.setOpaque(true); jl.setIcon(new ImageIcon("D:/Project/router2.jpg")); jl.setBounds(x, y,jl.getPreferredSize().width,jl.getPreferredSize().height); for(Component c :lcomponent) { flag=true; Rectangle r4=c.getBounds(); int x1=(int) r4.getX(); int y1=(int) r4.getY(); Rectangle r5 = new Rectangle(new Point(x1-60, y1-60),new Dimension(170,170)); if(r5.contains(p)){ //To ensure that two labels do not overlap or are too close flag = false; // to each other break; }} if(flag) { p2.add(jl); //p2 is a panel Component c2 = p2.getComponentAt(x,y); p2.repaint(); lcomponent.add(c2); //lcomponent is an ArrayList<Component> to store all the labels added to the panel } 2.to remove the label: p2.remove(); p2.repaint();

  • How to change webservice url endpoint ?

    - by EugeneP
    I generated a web-service client using JBoss utils (JAX-WS compatible) using Eclipse 'web service client from a wsdl'. So, the only thing I provided was a url to a web-service. Now, the web service provider tells me to change the "client endpoint" of the web-service. What is it and how to change it?

  • IVR-style dialog system / workflow / menu

    - by unbeli
    I need to build a dialog system similar to IVR used in call centers. My system is not phone-based, but the dialog is similar. Something like System: "Main menu: Enter [1] for menu1, [2] for menu2" User: [1] System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [7] System: "What??" System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [2] ... and so on I want to have a nice declarative description of all the possible options and a nice way to run through that tree, guided by user input. Already considered: ANTLR-generated lexer/parser (seems to be an overkill), SCXML-based state machine (seems like only transitions can be declared, the rest needs to be coded)

  • Why String.replaceAll() don't work on this String ?

    - by Aloong
    //This source is a line read from a file String src = "23570006,music,**,wu(),1,exam,\"Monday9,10(H2-301)\",1-10,score,"; //This sohuld be from a matcher.group() when Pattern.compile("\".*?\"") String group = "\"Monday9,10(H2-301)\""; src = src.replaceAll("\"", ""); group = group.replaceAll("\"", ""); String replacement = group.replaceAll(",", "#@"); System.out.println(src.contains(group)); src = src.replaceAll(group, replacement); System.out.println(group); System.out.println(replacement); System.out.println(src); I'm trying to replace the "," between \"s so I can ues String.split() latter. But the above just not working , the result is: true Monday9,10(H2-301) Monday9#@10(H2-301) 23570006,music,**,wu(),1,exam,Monday9,10(H2-301),1-10,score, but when I change the src string to String src = "123\"9,10\"123"; String group = "\"9,10\""; It works well true 9,10 9#@10 1239#@10123 What's the matter with the string???

  • comparator with null values.

    - by pvgoddijn
    Hi, We have some code wich sorts a list of addresses based on the distance between their coordinates. this is done through collections.sort with a custom comparator. However from time to time an adress without coordinates is in the list causing a NullPointerException. My initial idea to fix this was to have the comparator return 0 as dististance for addresses where at least one of the coordinates is null. I fear this might lead to corruption of the order the 'valid' elements in the list. so is returning a '0' values for null data in a comparator ok, or is there a cleaner way to resolve this.

  • overwrite blackberry's send sms/mail method

    - by Luis Armando
    I haven't been able to found this on Google, so I thought maybe somene here knew if this was possible and if so, how to implement it =) thanks in advance for any answers! What I am aiming for is overwriting this method so I can perform some actions before the sms/mail gets sent, then just allow it to perform its normal actions.

  • @Autowire strange problem

    - by Javi
    Hello, I have a strange behaviour when autowiring I have a similar code like this one, and it works @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2{ ... } The problem is that I need that the Class2 implements an interface so I've only changed the Class2 so it's now like: @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2 implements IServiceReference<Class3, Long>{ ... } public interface IServiceReference<T, PK extends Serializable> { public T reference(PK id); } with this code I get a org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type for Class2. It seems that @ Transitional annotation is not compatible with the interface because if I remove the @Transitional annotation or the "implements IServiceReference" the problem disapears and the bean is injected (though I need to have both in this class). It also happens if I put the annotation @Transitional in the methods instead of in the Class. I use Spring 3.0.2 if this helps. Is not compatible the interface with the transactional method? May it be a Spring bug? Thanks

  • Algorithm to determine which points should be visible on a map based on zoom

    - by lgratian
    Hi! I'm making a Google Maps-like application for a course at my Uni (not something complex, it should load the map of a city for example, not the whole world). The map can have many layers, including markers (restaurants, hospitals, etc.) The problem is that when you have many points and you zoom out the map it doesn't look right. At this zoom level only some points need to be visible (and at the maximum map size, all points). The question is: how can you determine which points should be visible for a specified zoom level? Because I have implemented a PR Quadtree to speed up rendering I thought that I could define some "high-priority" markers (that are always visible, defined in the map editor) and put them in a queue. At each step a marker is removed from the queue and all it's neighbors that are at least D units away (D depends on the zoom levels) are chosen and inserted in the queue, and so on. Is there any better way than the algorithm I thought of? Thanks in advance!

  • Google datastore stats

    - by Keyur
    I am querying the __Stat_Kind__ kind. It does not return me entities about kinds that currently exist in the datastore but it includes entities about kinds that I had deleted more than a week ago. I am not so much concerned about it returning me the non-existent kinds - the doc does mention this scenario after all. But I am concerned that it does not return me info about my current kinds. Is this a known issue or am I doing something wrong? To folks on the app engine team: Also, on the dev server neither __Stat_Kind__ nor __Stat_Total__ return any entities. Which means I need to deploy my app to appspot before I can test this behavior. It would be nice if the dev server did return some basic info. Thanks, Keyur

  • JLabel with separate text and icon background colours

    - by emeraldjava
    Hey, I have a simple Jlabel element with text and icon setting the background changes the full label colour. I want to be able to only render the background colour on the text section of the label, ie - to have separate backgrounds/foregrounds for the icon and text. Selecting/deselecting the label will flip the colour behind the icon and text. Is this possible to do this by just extending JLabel, and if so which methods should i be looking to customise? My alternative idea is to create a panel with two separate label elements, one with an icon the other with text. It seems a bit messy, and before i start i'm wondering is there a smarter way of achieving this with Swing.

  • How to modularize a JSF/Facelets/Spring application with OSGi?

    - by lexicore
    I'm working with very large JSF/Facelets applications which use Spring for DI/bean management. My applications have modular structure and I'm currently looking for approaches to standardize the modularization. My goal is to compose a web application from a number of modules (possibly depending on each other). Each module may contain the following: Classes; Static resources (images, CSS, scripts); Facelet templates; Managed beans - Spring application contexts, with request, session and application-scoped beans (alternative is JSF managed beans); Servlet API stuff - servlets, filters, listeners (this is optional). What I'd like to avoid (almost at all costs) is the need to copy or extract module resources (like Facelets templates) to the WAR or to extend the web.xml for module's servlets, filters, etc. It must be enough to add the module (JAR, bundle, artifact, ...) to the web application (WEB-INF/lib, bundles, plugins, ...) to extend the web application with this module. Currently I solve this task with a custom modularization solution which is heavily based on using classpath resources: Special resources servlet serves static resources from classpath resources (JARs). Special Facelets resource resolver allows loading Facelet templates from classpath resources. Spring loads application contexts via the pattern classpath*:com/acme/foo/module/applicationContext.xml - this loads application contexts defined in module JARs. Finally, a pair of delegating servlets and filters delegate request processing to the servlets and filters configured in Spring application contexts from modules. Last days I read a lot about OSGi and I was considering, how (and if) I could use OSGi as a standardized modularization approach. I was thinking about how individual tasks could be solved with OSGi: Static resources - OSGi bundles which want to export static resources register a ResourceLoader instances with the bundle context. A central ResourceServlet uses these resource loaders to load resources from bundles. Facelet templates - similar to above, a central ResourceResolver uses services registered by bundles. Managed beans - I have no idea how to use an expression like #{myBean.property} if myBean is defined in one of the bundles. Servlet API stuff - use something like WebExtender/Pax Web to register servlets, filters and so on. My questions are: Am I inventing a bicycle here? Are there standard solutions for that? I've found a mentioning of Spring Slices but could not find much documentation about it. Do you think OSGi is the right technology for the described task? Is my sketch of OSGI application more or less correct? How should managed beans (especially request/session scope) be handled? I'd be generally graefult for your comments.

  • What is the best IDE?

    - by venom
    Hello. As a not so experienced man in programming, I start to use netbeans PLATFORM. And I am really impressed by its power (for rich desktop app). I have been learning the programming in another way on university. I have never thought that something as powerful as nb Platform exists. My idea was that 30 people work on some rich desktop app for more than year to make it "beta". Now I know, that it is much more easier. But, I have never be satisfied with my own opinions about "something is best". I am still looking for better mouse trap. So the question is: What is most powerful IDE you know? (it does not strongly depends on language, it means if some combination of language/IDE is really powerful, feel free to answer.)

  • Just curious, in NetBeans IDE 6.1 how can i get icons for my custom GUI components in the GUI editor

    - by Coder
    This is by no means really important, i was just wondering if the community knows how to put icons for my custom GUI components that show up in the NetBeans GUI designer. What i did was make several Swing components and then i use the menu options to add them to the GUI pallete, but they show up with "?" icons. It would be nice if they showed up with icons similar to swing components such as JButtons, especially for components which are subclassed for Swing components. Thanks!
