  • can a webservice load jars during run time

    - by KItis
    I have created a simple web-service using Java. i want to load jars related to web-service during runtime. I have done this task for normal Java application. there what I did was JarFile jar = new JarFile(f.getPath()); final Manifest manifest = jar.getManifest(); final Attributes mattr = manifest.getMainAttributes(); // Read the manifset in jar files and get the Name attribute // whare it specified the class that need to load //for (Object a : mattr.keySet()) { for (Iterator iter = mattr.keySet().iterator(); iter.hasNext();) { Object obj = (Object)iter.next(); if ("ServiceName".equals(obj.toString())) className = mattr.getValue((Name) obj); //System.out.println(className); } /* * Create the jar class loader and use the first argument passed * in from the command line as the jar file to use. */ JarClassLoader jarLoader = new JarClassLoader(f.getPath()); /* Load the class from the jar file and resolve it. */ Class c = jarLoader.loadClass(className, true); My problem is can I put jars that need to be loaded during run time in to separate folder rather than putting in to WEBINF folder. do i have to put jars both in axis and web-application. thanks in advance for any contribution for this question.

  • Place JComponent On The Top Of JXLayer

    - by Yan Cheng CHEOK
    Hello, currently, I had successful applying JXLayer on my charting component, to draw a yellow information box on the top of it. final org.jdesktop.jxlayer.JXLayer<ChartPanel> layer = new org.jdesktop.jxlayer.JXLayer<ChartPanel>(this.chartPanel); this.chartLayerUI = new ChartLayerUI<ChartPanel>(this); layer.setUI(this.chartLayerUI); At the same time, I wish to add the following JComponent (DefaultDrawingView) on the top of JXLayer. This JComponent has the ability 1) To receive mouse event to draw figures on itself. Within ChartLayerUI, I add the following code @Override @SuppressWarnings("unchecked") public void installUI(JComponent c) { super.installUI(c); JXLayer<JComponent> l = (JXLayer<JComponent>) c; l.getGlassPane().setLayout(new java.awt.BorderLayout()); // this.view is DefaultDrawingView drawing object. l.getGlassPane().add(this.view, java.awt.BorderLayout.CENTER); } However, after having the above code, I get the following outcome 1) My charting component ChartPanel are being blocked by DefaultDrawingView 2) My charting component no longer able to receive mouse event. What I wish is that A) ChartPanel and DefaultDrawingView able to show up B) ChartPanel and DefaultDrawingView able to receive mouse event Is there other steps I had missed out, or did wrong? Thanks.

  • Limit TCP requests per IP

    - by asmo
    Hello! I'm wondering how to limit the TCP requests per client (per specific IP) in Java. For example, I would like to allow a maximum of X requests per Y seconds for each client IP. I thought of using static Timer/TimerTask in combination with a HashSet of temporary restricted IPs. private static final Set<InetAddress> restrictedIPs = Collections.synchronizedSet(new HashSet<InetAddress>()); private static final Timer restrictTimer = new Timer(); So when a user connects to the server, I add his IP to the restricted list, and start a task to unrestrict him in X seconds. restrictedIPs.add(socket.getInetAddress()); restrictTimer.schedule(new TimerTask() { public void run() { restrictedIPs.remove(socket.getInetAddress()); } }, MIN_REQUEST_INTERVAL); My problem is that at the time the task will run, the socket object may be closed, and the remote IP address won't be accessible anymore... Any ideas welcomed! Also, if someone knows a Java-framework-built-in way to achieve this, I'd really like to hear it.

  • google site rank from search word

    - by user72185
    Hi, is it possible (a Google API or something) to get the ranking of a website given a search word? It's the code equivalent of doing a Google search for a word, then browsing through the results until you find the website you look for. By ranking I mean the position in the pages found, e.g. the site is number 4000 when searching for some word. Thanks!

  • JDialog setResizable(false) is not working in Window Title Bar Menu

    - by jolonaleur
    JDialog setResizable(false) is not working in Window Title Bar Menu Windows XP SP2 Java JRE 1.6.0_11-b03 Behavior varies. Sometimes, the Maximize and Minimize item on the window menu is disabled and sometimes enabled. Steps to reproduce enabled Maximize and Minimize button: Show the JDialog with setResizable(false) Open another window, say for example Notepad. Right-click on the window title bar of Notepad and click Maximize. Go to your JDialog and right click on the window title bar. Maximize window is enabled. Likewise, to disable the Maximize item for the JDialog, go to the maximized Notepad window and right click on title bar. Maximize item is disabled in the Notepad window. Go the your JDialog and right click on the title bar, notice that the Maximize item is also disabled. Note that my application can not use the defaultLookAndFeel method of java dialogs. The bug report related to this was for Solaris OS but that was already ages ago. bug report Is there any workaround? Thanks.

  • Alternatives to static methods on interfaces for enforcing consistency

    - by jayshao
    In Java, I'd like to be able to define marker interfaces, that forced implementations to provide static methods. For example, for simple text-serialization/deserialization I'd like to be able to define an interface that looked something like this: public interface TextTransformable<T>{ public static T fromText(String text); public String toText(); Since interfaces in Java can't contain static methods though (as noted in a number of other posts/threads: here, here, and here this code doesn't work. What I'm looking for however is some reasonable paradigm to express the same intent, namely symmetric methods, one of which is static, and enforced by the compiler. Right now the best we can come up with is some kind of static factory object or generic factory, neither of which is really satisfactory. Note: in our case our primary use-case is we have many, many "value-object" types - enums, or other objects that have a limited number of values, typically carry no state beyond their value, and which we parse/de-parse thousands of time a second, so actually do care about reusing instances (like Float, Integer, etc.) and its impact on memory consumption/g.c. Any thoughts?

  • Start developing a database application using Oracle + Net Beans

    - by Ranhiru
    I have thought of creating my first database application for one of my projects using Oracle and Java. I have chosen Netbeans as my development environment. I have a few questions to getting started. Please bare with me as I'm a complete beginner to Oracle + Netbeans This will be a data intensive (yet still for a college project) database application. I do not need 1000 user concurrency or any other very advanced features but basic stuff such as triggers, stored procedures etc. Will the 11g "Express" (XE) suffice for my requirements? Do i need any Java to Oracle bridge (database connectivity driver eg. ODBC etc) for Netbeans to connect to the oracle database? If yes, what are they? Does Netbeans support Oracle databases natively? Any easy to follow guide on how do i connect to the database and insert/retrieve/display data on a J2SE application? (I know that i should Google this but if there's any guide previously followed by anyone and is considered easy, it would be greatly appreciated.)

  • Convert SVG to PDF

    - by Adrian Smith
    How would one go about converting a SVG file to a PDF programatically? (I need to alter the SVG in certain respects before generating the PDF so simply pre-converting it using a tool won't be sufficient.) Ideally using Java but Perl or PHP would be fine too. Obviously I am basically considering Apache FOP and Batik with Java. However no matter how long I search I cannot find a simple introduction on how to do it. Things like SVGConverter have descriptions like "Defines the interface for classes that are able to convert part or all of a GraphicContext", but I don't really know what that means. I have this feeling there must be an API to do this quite simply, provided by FOP or Batik, but I'm just not able to find it at the moment (or perhaps it really doesn't exist.) In terms of the supported SVG features I need, the file has some paths which are filled with some linear gradients. Ideally if I could pass the SVG in as a DOM Document that would be ideal; then I would load my template SVG file, change it as specified by the user, and then generate the PDF.

  • Which web framework or technologies would suit me?

    - by Suraj Chandran
    Hi, I had been working on desktop apps and server side(non web) for some time and now I am diving in to web first time. I plan to write a scalable enterprise level app. I have worked with Java, Javascript, Jquery etc. but I absolutely hate jsp. So is there any framework that focuses on developing enterprise level web apps without jsp. I liked Wicket's approach, but I think there is a little lack of support of dynamic html in it and jquery(yes i looked at wiquery). Also I feel making wicket apps scalable would take some sweat. Can Spring MVC, Struts2 etc. help me make with this with just using say Java, JavaScript, and JQuery. Or are there any other options for me like Wicket. Please do forgive if anything above looks insane, I am still working on my understanding with enterprise web apps. NOTE: If you think that I should take a different direction or approach, please do suggest!

  • Preserving timestamps on Clojure .clj files when building shaded jar via Maven Shade Plugin

    - by Dereference
    When using the maven-shade-plugin to package our jar artifact that contained a few Clojure libs and some Java. We were using AOT compilation for our Clojure code. When we loaded the jar, it was having very slow load times. AOT compilation is supposed to help this quite a bit, but that wasn't what we were seeing. We noticed in java jar -verbose output that there was a lot of JVM__DEFINE_CLASS calls happening when Clojure classes were being loaded. This didn't make sense, since more of our Clojure code was AOT compiled to .class files. Turns out the maven-shade-plugin creates all new files, with new timestamps in the final artifact Clojure uses the timestamp information on a .clj file vs. a .class file, to determine if the file needs to be recompiled. The maven-shade-plugin was causing the .clj file and it's associated .class file to have the same timestamp, so Clojure always chose to dynamically recompile the source. The only workaround that we have been able to figure out, at this point, is to write a script that would re-open the shaded jar and bump the .clj file timestamps back to some time in the past, so that they wouldn't be equal to the timestamps of their associated .class files. Does anyone know of a better approach?

  • Is there a JSON library that can serialize Proxy objects?

    - by gmoore
    Using ActiveObjects as my ORM and Gson as my JSON processor. Ran into a problem going toJson from persisted objects. The problem is that my persisted class is actually an Interface and AO is proxying that object under the hood. Here's some sample code: Venue venue = manager.get(Venue.class, id); gson.toJson(venue); Comes up with this exception: java.lang.UnsupportedOperationException: Expecting parameterized type, got interface java.lang.reflect.InvocationHandler. Are you missing the use of TypeToken idiom? See http://sites.google.com/site/gson/gson-user-guide#TOC-Serializing-and... Because venue.getClass().getName() gives: $Proxy228 I've tried a few solutions in various combinations: gsonBuilder.registerTypeAdapter(Venue.class, newVenueSerializer()); Type listType = new TypeToken<Venue>() {}.getType(); Nothing has worked so far and I'm using a wonky field-by-field workaround. Any suggestions? I'm not married to Gson, so if there's an alternative library that can do this I'd be happy to use it.

  • SWT: cleaning up before application exit

    - by Alexey Romanov
    What is the best way for an SWT application to clean up resources before application exit? I see two options: 1) Add a DisposeListener to main window (or better, to the Display). Will it get run if an uncaught exception happens? 2) Use a shutdown hook. Any problems to be aware of there which aren't mentioned in Design of the Shutdown Hooks API?

  • Problem painting JLabel class to another JPanel class

    - by jjpotter
    I have created a class that extends JLabel to use as my object moving around a JPanel for a game. import javax.swing.*; public class Head extends JLabel { int xpos; int ypos; int xvel; int yvel; ImageIcon chickie = new ImageIcon("C:\\Users\\jjpotter.MSDOM1\\Pictures\\clavalle.jpg"); JLabel myLabel = new JLabel(chickie); public Head(int xpos, int ypos, int xvel, int yvel){ this.xpos = xpos; this.ypos = ypos; this.xvel = xvel; this.yvel = yvel; } public void draw(){ myLabel.setLocation(xpos, ypos); } public double getXpos() { return xpos; } public double getYpos() { return ypos; } public int getXvel() { return xvel; } public int getYvel() { return yvel; } public void setPos(int x, int y){ xpos = x; ypos = y; } } I am then trying to add it onto my JPanel. From here I will randomly have it increment its x and y coordinates to float it around the screen. I can not get it to paint itself onto the JPanel. I know there is a key concept I am missing here that involves painting components on different panels. Here is what I have in my GamePanel class import java.awt.Dimension; import java.util.Random; import javax.swing.*; public class GamePanel extends JPanel { Random myRand = new Random(); Head head = new Head(20,20,0,0); public GamePanel(){ this.setSize(new Dimension(640, 480)); this.add(head); } } Any suggestions on how to get this to add to the JPanel? Also, is this a good way to go about having the picture float around the screen randomly for a game?
