  • War wont deploy "Unresolved <ejb-link>" Glassfish 3, Netbeans 7

    - by Ime Imee
    I have enterprise aplication with ejb and war module, and since I created local interface web module wont deploy. It builds fine. EJB project is referenced inside web project. Also when I delete <ejb-local-ref> from web.xml it deploys, but then lookup method fails.

  • Silverlight 4 toolkit, charting and lineSeries is null

    - by Snake
    Hi, I create a Silverlight Chart, with the Silverlight 4 toolkit, the April release.

  • How do I base a style on a Silverlight toolkit theme style

    - by Ian Oakes
    I've being trying to add a theme from the Silverlight toolkit to a project. In the project there are a number of existing styles used in the layout. The problem is when any control has an explict style applied to it does not receive any attributes of the style from the theme. In WPF I would use something like BasedOn={x:Type TextBox}, but this is not supported in Silverlight. I've considered going through the theme and setting a key for every style and then using BasedOn to create both an implicit style to use with the ImplictStyleManager, as well as another explicit style for use with the existing styled controls. Have you got any better ideas?

  • Switching Timezones in Perl's Template::Toolkit plugin Template::Plugin::Date

    - by aidan
    I have a calendar on my website, generated in Perl using Template::Toolkit and Template::Plugin::Date. It highlights the current day. I achieve this by iterating through all the dates (as I print the calendar) and comparing against the current date. Something like this: [% IF cur_date == date.format(format = '%Y-%m-%d') %] ... [% END %] It all works well until someone in Australia looks at it. (They are in a different timezone to me and my server in the UK). What's the best way to get Template::Plugin::Date to use a different time zone? It accepts a 'locale' parameter, but AFAIK this is only used for formatting.

  • Which Java Framework is best suited for a web application with reusable content/behavior

    - by Jacob
    I come from a .NET background and need to do a web project in Java. I have read a bit on all the different Java web frameworks out there: JSF, Stripes, Wicket, Tapestry etc. But I would like to hear from people with real-life expertise with these frameworks. Of course I want a framework that is up to date, supports AJAX, is cool and so on, but one of my main criteria is the ability to somehow create reusable components / tags. The customer needs to be able to move tags/components around without too much problem in order to customize it for their specific needs. In ASP.NET Webforms I would use custom controls and user controls for this, and in ASP.NET MVC I would use user controls as well as home made custom controls. So what Java frameworks excel in this? My own superficial research seems to conclude that JSF supports some kind of custom controls (Bear in mind i am not only talking about layout reuse, but also behavior reuse, so if for example the customer / client wants a customer list on page x and not only on page Y, he would simply put in a <jr:CustomerList runat="server" .... /> (fictional example with ASP.NET Webforms syntax)).

  • Java works under Firefox but crashes Internet Explorer

    - by Dominic Grenier
    Java works under Firefox and Chrome but not under IE. Here's what I tried (the advice normally given on forums): Java applet activated in tools - internet options - security tab - personnalise - Java applets Activated in tools - manage add-ons - tool bars and extensions - Java (tm) SSV2 helper - Activate Activated in tools - internet options - advanced tab - Use JRE for applet I've also deleted my temporary internet files (with Ccleaner), Reinstalled IE8 It is also set as the default Java for IE through the control panel - Java - Advanced tab - default Java for browsers - Microsoft Internet Explorer IE version: 8.0.6001.18702 Java version: 1.7.0_03. (also tried with 1.6.0_31) Windows XP SP3. Any advice? Thanks :) edit: I have activated the ActiveX controls through manage add-ons - all add-ons but now, although the coffe cup loading screen appears (which did not before) it makes IE crash (which is new). I might have fiddled too much with the registry by trying to completely remove Java to reinstall it, so I ran "rereg" (a tool to repair dlls and their registry entries) without success.

  • Subsonic and the VB.net 2005 interop toolkit

    - by wja
    I have an application I am converting over from vb6 to vb.net 2.0/3.5. Using Subsonic 2.2 and the vb.net Interop Toolkit 2005. Cannot seem to get the .net form using subsonic to work inside the interop environment. It keeps saying it cannot find the subsonic service provider in the app.config. But I know it is there. Has anyone used these two toolkits together successfully? Will subsonic even work inside the interop environment in that way? Thanks in advance!

  • Small Open source and free java applications

    - by user1089770
    I am a Perl Developer who has just stepped into the Java world and I want to be very proficient in Java EE development. However, I have found that, being a Perl guy, I have very high MTI(Mother Tongue Influence). Indians will know what MTI is. For others, it can be defined as an influence of your "main" language whenever you "speak" your new language. In other words, our mind converts/translates what we want to "say" in the new language based on the "main" language, which can be quite absurd or meaning less in the "new" language. Coming back to the point, as a result of this MTI, many lines of my code has this Perl influence and it is absurd and useless for production. Hence, I'd like to see or better do some research on existing small to medium open source java applications, so that I will know how I can "speak" in the native way of the "new" language. Some examples in PHP will be : WordPress, Zend etc. So I'd really appreciate if you guys could suggest any such apps. Apps that have a great commercial value are highly preferred

  • Look Inside WebLogic Server Embedded LDAP with an LDAP Explorer

    - by james.bayer
    Today a question came up on our internal WebLogic Server mailing lists about an issue deleting a Group from WebLogic Server.  The group had a special character in the name. The WLS console refused to delete the group with the message a java.net.MalformedURLException and another message saying “Errors must be corrected before proceeding.” as shown below. The group aa:bb is the one with the issue.  Click to enlarge. WebLogic Server includes an embedded LDAP server that can be used for managing users and groups for “reasonably small environments (10,000 or fewer users)”.  For organizations scaling larger or using more high-end features, I recommend looking at one of Oracle’s very popular enterprise directory services products like Oracle Internet Directory or Oracle Directory Server Enterprise Edition.  You can configure multiple authenicators in WebLogic Server so that you can use multiple directories at the same time. I am not sure WebLogic Server supports special characters in group names for the Embedded LDAP server, but in this case both the console and WLST reported the same issue deleting the group with the special character in the name.  Here’s the WLST output: wls:/hotspot_domain/serverConfig/SecurityConfiguration/hotspot_domain/Realms/myrealm/AuthenticationProviders/DefaultAuthenticator> cmo.removeGroup('aa:bb') Traceback (innermost last): File "<console>", line 1, in ?

Follow the instructions here, being sure to change the authentication credentials to the Embedded LDAP server to some value you know, as by default they are some unknown value.  You’ll need to reboot the WebLogic Server Admin Server after making this change. Now configure JXplorer to connect as described in the documentation.  I’ve circled the important inputs.  In this example, my domain name is “hotspot_domain” which listens on the localhost listen address and port 7001.  The cn=Admin user name is a constant identifier for the Administrator of the embedded LDAP and that does not change, but you need to know what it is so you can enter it into the tool you use. Once you connect successfully, you can explore the entries and in this case delete the group that is no longer desired.

  • Verizon Wireless Supports its Mission-Critical Employee Portal with MySQL

    - by Bertrand Matthelié

Verizon Wireless built the first wide-area wireless broadband network and delivered the first wireless consumer 3G multimedia service in the US, and offers global voice and data services in more than 200 destinations around the world. To support 4.2 million daily wireless transactions and 493,000 calls and emails transactions produced by 94.2 million retail customers, Verizon Wireless employs over 78,000 employees with area headquarters across the United States. The Business Challenge Seeing the stupendous rise in social media, video streaming, live broadcasting…etc which redefined the scope of technology, Verizon Wireless, as a technology savvy company, wanted to provide a platform to its employees where they could network socially, view and host microsites, stream live videos, blog and provide the latest news. The IT team at Verizon Wireless had abundant experience with various technology platforms to support the huge number of applications in the company. However, open-source products weren’t yet widely used in the organization and the team had the ambition to adopt such technologies and see if the architecture could meet Verizon Wireless’ rigid requirements. After evaluating a few solutions, the IT team decided to use the LAMP stack for Vzweb, its mission-critical, 24x7 employee portal, with Drupal as the front end and MySQL on Linux as the backend, and for a few other internal websites also on MySQL. The MySQL Solution Verizon Wireless started to support its employee portal, Vzweb, its online streaming website, Vztube, and internal wiki pages, Vzwiki, with MySQL 5.1 in 2010. Vzweb is the main internal communication channel for Verizon Wireless, while Vztube hosts important company-wide webcasts regularly for executive-level announcements, so both channels have to be live and accessible all the time for its 78,000 employees across the United States. However during the initial deployment of the MySQL based Intranet, the application experienced performance issues. High connection spikes occurred causing slow user response time, and the IT team applied workarounds to continue the service. A number of key performance indexes (KPI) for the infrastructure were identified and the operational framework redesigned to support a more robust website and conform to the 99.985% uptime SLA (Service-Level Agreement). The MySQL DBA team made a series of upgrades in MySQL: Step 1: Moved from MyISAM to InnoDB storage engine in 2010 Step 2: Upgraded to the latest MySQL 5.1.54 release in 2010 Step 3: Upgraded from MySQL 5.1 to the latest GA release MySQL 5.5 in 2011, and leveraging MySQL Thread Pool as part of MySQL Enterprise Edition to scale better After making those changes, the team saw a much better response time during high concurrency use cases, and achieved an amazing performance improvement of 1400%! In January 2011, Verizon CEO, Ivan Seidenberg, announced the iPhone launch during the opening keynote at Consumer Electronic Show (CES) in Las Vegas, and that presentation was streamed live to its 78,000 employees. The event was broadcasted flawlessly with MySQL as the database. Later in 2011, Hurricane Irene attacked the East Coast of United States and caused major life and financial damages. During the hurricane, the team directed more traffic to its west coast data center to avoid potential infrastructure damage in the East Coast. Such transition was executed smoothly and even though the geographical distance became longer for the East Coast users, there was no impact in the performance of Vzweb and Vztube, and the SLA goal was achieved. “MySQL is the key component of Verizon Wireless’ mission-critical employee portal application,” said Shivinder Singh, senior DBA at Verizon Wireless. “We achieved 1400% performance improvement by moving from the MyISAM storage engine to InnoDB, upgrading to the latest GA release MySQL 5.5, and using the MySQL Thread Pool to support high concurrent user connections. MySQL has become part of our IT infrastructure, on which potentially more future applications will be built.” To learn more about MySQL Enterprise Edition, Get our Product Guide.

  • How do I fix this Windows 7 wireless connectivity issue?

    - by Charles Randall
    I have a laptop with an Intel Wireless Centrino 6300 module. Recently, the machine has stopped properly connecting to my wireless router. It will get stuck in a loop of connecting, then disconnecting and reconnecting. While connected, it will simply say "No Internet Access." Running inSSIDer 2.0, it shows my network jumping around between two channels -- I know this isn't the case, because I've set my router to sit on one single channel. My MacBook Pro, Boxee Box, PS3, and Xbox 360 all connect fine to the wireless and have no problems at all. I know it's not the wireless module, as I bought a second one recently assuming the first had died -- but I get the same behavior with both. Sometimes, I can fix the issue temporarily by deleting the network (Using the Manage Wireless Networks page), and then re-adding it (via standard wireless methods). Then it will work for a few days. But inevitably the problem comes back, and now the laptop simply won't connect to the wireless at all, even if I take steps that usually work. Since I've ruled out the hardware, and it's unlikely some kind of interference issue (because I would expect to see it on any multitude of other devices), I would think at this point that it's a problem with Windows itself. One thing that might be a hint, even though I delete the network, when I add it again, it's always listed as "Wireless Network Connection 2" even though there isn't another in the list.

  • WCF Service, Java JApplet client, transport error 405

    - by Juan Zamudio
    Hi all, I'm having a problem with a WCF Service and Java Client, I will try to give as much information as i can, thanks for your time. The Endpoint of the server is BasicHttpBinding, I tried hosting the server as a Windows Service and in IIS but nothing changed. The weird thing is that the Client works great if I use a simple class, in the moment I switch the class to an JApplet I get the problem mentioned. I'm using Eclipse as an IDE, I tried Axis and Metro to generate the stub with the same bad results. Here is an example of the Java class where everything is working public class TestSoaMetro { public String TestMethod(){ String result=null; IDigitalSignatureService aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); try { result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } Here is the example of the JApplet where I get the error: public class TestSoaMetroApplet extends JApplet { public void init() { Container content = getContentPane(); content.setBackground(Color.white); content.setLayout(new FlowLayout()); String result= this.TestMethod(); JLabel label = new JLabel(result); content.add(label); } public String TestMethod(){ String result=null; IDigitalSignatureService aa = null; try { aa = new DigitalSignatureService().getBasicHttpBindingEndpoint(); result= aa.getData("1", "id002962"); } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) { // TODO Auto-generated catch block e.printStackTrace(); } return result; } } In the moment the Applet loads I get the error, is the exact same call so I don't understand why I get the exception using the Applet. I Also tried to call this from a Silverlight client and I was getting a security exception, this is where I found out about clientaccesspolicy.xml and crossdomain.xml, I added clientaccesspolicy.xml to the service and the Silverlight Client works great, so I decided to try crossdomain.xml and nothing, the Applet still does not work. I will put the stack trace at the end, thanks all for your time.

  • iwlwifi on lenovo z570 disabled by hardware switch

    - by Kevin Gallagher
    It was working fine with windows 7. The hardware switch is not disabled. I've toggled it back and forth dozens of times. The wifi light never turns on and it always lists as hardware disabled. I have the latest updates installed. I've been searching for solutions, but none of them seem to work for me. I've tried removing acer-wmi. I've tried setting 11n_disable=1. I've tried resetting the bios. I've tried using rfkill to unblock (only removes soft block). I've rebooted dozens of times. The wifi light turns off as soon as grub loads. Edit: I have a usb edimax wireless nic. It shows hardware disabled as well (although rfkill lists as unblocked). If I unload iwlwifi the usb nic works fine. uname -a `Linux xxx-Ideapad-Z570 3.2.0-55-generic #85-Ubuntu SMP Wed Oct 2 12:29:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linu`x rfkill list 19: phy18: Wireless LAN Soft blocked: no Hard blocked: yes dmesg [43463.022996] Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree: [43463.023002] Copyright(c) 2003-2011 Intel Corporation [43463.023107] iwlwifi 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [43463.023190] iwlwifi 0000:03:00.0: setting latency timer to 64 [43463.023253] iwlwifi 0000:03:00.0: pci_resource_len = 0x00002000 [43463.023257] iwlwifi 0000:03:00.0: pci_resource_base = ffffc900057c8000 [43463.023261] iwlwifi 0000:03:00.0: HW Revision ID = 0x0 [43463.023797] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X [43463.024013] iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Wireless-N 1000 BGN, REV=0x6C [43463.024250] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S [43463.045496] iwlwifi 0000:03:00.0: device EEPROM VER=0x15d, CALIB=0x6 [43463.045501] iwlwifi 0000:03:00.0: Device SKU: 0X50 [43463.045504] iwlwifi 0000:03:00.0: Valid Tx ant: 0X1, Valid Rx ant: 0X3 [43463.045542] iwlwifi 0000:03:00.0: Tunable channels: 13 802.11bg, 0 802.11a channels [43463.045744] iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable radio.

  • setting something disposed or invisible java

    - by OVERTONE
    this might be simple enough as just inserting the right method but i cant seem to get it right. i have a simple program with two buttons. each one changes the picture above them. but anytime i click the buttons i get some odd awt event queue error. i think its because im trying to add something to a frame after its already been made. package icnon; import javax.imageio.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class FrameIconExample extends JFrame implements ActionListener { JLabel j; JPanel p, l, k; JButton picOne, picTwo; Container cPane; public FrameIconExample() { JButton picOne = new JButton("picOne"); JButton picTwo = new JButton("picTwo"); picOne.setName("picOne"); picTwo.setName("picTwo"); picOne.addActionListener(this); picTwo.addActionListener(this); JPanel p = new JPanel(new GridLayout(2, 1)); JPanel l = new JPanel(new FlowLayout()); JPanel k = new JPanel(new FlowLayout()); cPane = getContentPane(); j = new JLabel(new ImageIcon("../meet/src/images/beautiful-closeup-portrait-photography.jpg")); l.add(j); k.add(picOne); k.add(picTwo); p.add(l); p.add(k); add(p); } public static void main(String[] args) { FrameIconExample frame = new FrameIconExample(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(new Dimension(300, 800)); frame.setTitle("Frame Icon Example"); // Display the form frame.setVisible(true); } @Override public void actionPerformed(ActionEvent e) { JButton temp = (JButton) e.getSource(); String src = "../meet/src/images/Majken Kruse portrait - john.jpg"; //System.out.println(src + " " + temp.getName()); if(temp.getName().equalsIgnoreCase("picOne")) { src = "../meet/src/images/beautiful-closeup-portrait-photography.jpg"; System.out.println(src + " " + temp.getName()); Icon img; j = new JLabel(new ImageIcon(src)); l.add(j); System.out.println("1"); } if(temp.getName().equalsIgnoreCase("picTwo")) { src = "../icontest/images/Majken Kruse portrait - john.jpg"; System.out.println(src + " " + temp.getName()); Icon img; j = new JLabel(new ImageIcon(src)); l.add(j); System.out.println("2"); } } } its all just the one program so if you copy paste it into an editor you can see the stack trace. but the source of the image files wont be there. does anyone know how id do it? or where im goin wrong? stack trace: ../meet/src/images/beautiful-closeup-portrait-photography.jpg picOne Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at icnon.FrameIconExample.actionPerformed(FrameIconExample.java:68) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)

  • So LibGDX / Java or XNA / C# [on hold]

    - by Israel G.
    I am curious to know what will be better for me - LibGDX / Java or XNA / C#. I am on the same level with C# and Java (I am pretty advanced with both of them). I really want to get into game development, develop indie games and such. So what are the pros and cons of XNA and LibGDX, what do you prefer personally and why? Java - LibGDX is cross platform and uses OpenGL. C# - XNA is for windows only ( you can use monogame but it will hurt performance and other things), Unfortunately, XNA is not going to be supported anymore but I still see people that recommend it over libGDX. (XNA is more popular and has more tutorials then libGDX). So please help me to pick, I really don't know what to choose. Thanks a lot!

  • Connecting to Magento Web Services with Java

    - by kerry
    I was in the unenviable position of needing to connect to Magento, a PHP ecommerce platform, web services using Java.  It was kind of difficult to get the classes generated from the WSDL so I figured I would throw the results up on my github account for any other poor sap in a similar position. First, pull down the project using git: git clone git://github.com/webdevwilson/magento-java.git and build it with maven: mvn install Here is a quick example of how to pull an order using the generated classes: MagentoServiceLocator serviceLocator = new MagentoServiceLocator(); String url = "http://domain.com/index.php/api/v2_soap"; Mage_Api_Model_Server_V2_HandlerPortType port = serviceLocator.getMage_Api_Model_Server_V2_HandlerPort(url); String sessionId = port.login("username", "key"); SalesOrderEntity salesOrder = port.salesOrderInfo(sessionId, orderId); I also have some wrapper code in there that makes it a little easier to call the API. Checkout the project at https://github.com/webdevwilson/magento-java There is another option. it’s called Magja and it is located at google code.

  • Java code generation from class diagram

    - by Sanjay
    I'm on the way developing a Java application where user can provide a class diagram and get the corresponding Java code. I don't know how can I let the user interactively draw a class diagram in Java. I am currently getting the required parameters like attributes, functions directly from the user, and then I render a class diagram for him. I show the class diagram on a jdialog. Is there a better way to do this? This is an example of a class diagram, I need to generate this from a Java program, given the values and relationship.

  • Java or Python for internet application?

    - by jpartogi
    In choosing a technology for internet applications where the number of users may scale over time, which one should we consider: Java or Python? What are the considerations in choosing one and not the other? If speed and scalability is our main criteria, which one should we use? We have looked around and it seems that there are more websites that use Python [i.e : Quora, digg, reddit, bitbucket and disqus] than Java. Based on that, can we say that Python is more suitable for internet applications where speed and scalability is the main criteria? However we have browsed around and found some comments saying that Java is actually faster than Python. Thank you for your insights.

  • Submitting Java Code with Junit unit test

    - by LivingThing
    I have mostly work on simple java programs and compiled and run it with eclipse on Windows. So, i have no experience of using command prompt for compiling Java projects and do not have much info about what actually happens beneath the play button in Eclipse. Now i have to submit a Java application which will have basic operation on XML. My project also will have (JUnit) Unit Test. My question is related to submission of this Project. Which files would be necessary to submit the code. So, it executes properly? Does chosing eclipse as an IDE or junit as a unit testing framweork produces any dependenices i.e the executor of the program should have eclipse/libraries to execute the program on his machine?
