• Ubuntu 12.04 // Likewise Open // Unable to ever authenticate AD users

  - by Rob

  So Ubuntu 12.04, Likewise latest from the beyondtrust website. Joins domain fine. Gets proper information from lw-get-status. Can use lw-find-user-by-name to retrieve/locate users. Can use lw-enum-users to get all users. Attempting to login with an AD user via SSH generates the following errors in the auth.log file: Nov 28 19:15:45 hostname sshd[2745]: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:15:45 hostname sshd[2745]: PAM adding faulty module: pam_winbind.so Nov 28 19:15:51 hostname sshd[2745]: error: PAM: Authentication service cannot retrieve authentication info for DOMAIN\\user.name from remote.hostname Nov 28 19:16:06 hostname sshd[2745]: Connection closed by 10.1.1.84 [preauth] Attempting to login via the LightDM itself generates similar errors in the auth.log file. Nov 28 19:19:29 hostname lightdm: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:19:29 hostname lightdm: PAM adding faulty module: pam_winbind.so Nov 28 19:19:47 hostname lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "DOMAIN\user.name" Nov 28 19:19:52 hostname lightdm: [lsass-pam] [module:pam_lsass]pam_sm_authenticate error [login:DOMAIN\user.name][error code:40022] Nov 28 19:19:54 hostname lightdm: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:19:54 hostname lightdm: PAM adding faulty module: pam_winbind.so Attempting to login via a console on the system itself generates slightly different errors: Nov 28 19:31:09 hostname login[997]: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:31:09 hostname login[997]: PAM adding faulty module: pam_winbind.so Nov 28 19:31:11 hostname login[997]: [lsass-pam] [module:pam_lsass]pam_sm_authenticate error [login:DOMAIN\user.name][error code:40022] Nov 28 19:31:14 hostname login[997]: FAILED LOGIN (1) on '/dev/tty2' FOR 'DOMAIN\user.name', Authentication service cannot retrieve authentication info Nov 28 19:31:31 hostname login[997]: FAILED LOGIN (2) on '/dev/tty2' FOR 'DOMAIN\user.name', Authentication service cannot retrieve authentication info I am baffled. The errors obviously are correct, the file /lib/security/pam_winbind.so does not exist. If its a dependancy/required, surely it should be part of the package? I've installed/reinstalled, I've used the downloaded package from the beyondtrust website, i've used the repository, nothing seems to work, every method of installing this application generates the same errors for me. UPDATE : Hrmm, I thought likewise didn't use native winbind but its own modules. Installing winbind from apt-get uninstalls pbis-open (likewise) and generates failures when installing if pbis-open is installed first. Uninstalled winbind, reinstalled pbis-open, same issue as above. The file pam_winbind.so does not exist in that location. Setting up pbis-open-legacy (7.0.1.918) ... Installing Packages was successful This computer is joined to DOMAIN.LOCAL New libraries and configurations have been installed for PAM and NSS. Clearly it thinks it has installed it, but it hasn't. It may be a legacy issue with the previous attempt to configure domain integration manually with winbind. Does anyone have a working likewise-open installation and does the /etc/nsswitch.conf include references to winbind? Or do the /etc/pam.d/common-account or /etc/pam.d/common-password reference pam_winbind.so? I'm unsure if those entries are just legacy or setup by likewise. UPDATE 2 : Complete reinstall of OS fixed it and it worked seamlessly, like it was meant to and those 2 PAM files did NOT include entries for pam_winbind.so, so that was the underlying problem. Thanks for the assist.

• ADF Mobile - Update through Web Service (with ADF Business Components)

  - by Shay Shmeltzer

  In my previous blog entry I went over the basics of exposing ADF Business Components through service interfaces, and developing a simple ADF Mobile application that access and fetches data from those services. In this entry we'll dive a bit deeper  and address an update scenario through these web service interfaces. You can see the full demo video at the end of the post. In the first steps I show how to add an explicit method execution to fetch a specific record we want to update on the second page of a flow. For an update you'll be invoking a service method and passing the record you want to update as a parameter. As in many other Web services scenarios, we need to provide a complete object of specific type to the method. The ADF Web service data control helps you here by offering an object of this type that you can drag and drop into your page. The next step is to make sure to fill that object with the values you want to update. In the demo we do this through  coding in a backing bean that shows how to use the AdfmfJavaUtilities utility. The code gets the value from one field, gets a pointer to the parallel update field, and then copy from one to the other. At the end of the bean we manually execute the call to the update method on the Web service. Here is the demo: &amp;amp;amp;amp;&amp;lt;span id=&amp;quot;XinhaEditingPostion&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;lt;span id=&amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;quot;&amp;amp;amp;amp;gt;&amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;gt; Here is the code used in the backing bean in the demo above. package a.mobile;import oracle.adfmf.amx.event.ActionEvent;import javax.el.MethodExpression;import javax.el.ValueExpression;import oracle.adfmf.amx.event.ActionEvent;import oracle.adfmf.framework.api.AdfmfJavaUtilities;import oracle.adfmf.framework.model.AdfELContext;public class backing {    public backing() {    }    public void copyAndUpdate(ActionEvent actionEvent) {        // Add event code here...        AdfELContext adfELContext = AdfmfJavaUtilities.getAdfELContext();        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentName.inputValue}", String.class);        ValueExpression ve3 =            AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentName1.inputValue}", String.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.ManagerId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.ManagerId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.LocationId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.LocationId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        MethodExpression me = AdfmfJavaUtilities.getMethodExpression("#{bindings.updateDepartmentsView1.execute}", Object.class, new Class[] {});         me.invoke(adfELContext, new Object[] {});        }    }

• Communicating between C# application and Android app via bluetooth

  The android application acts as a server in this case. I have a main activity which creates a Thread to handle serverSocket and a different thread to handle the socket connection. I am using a uuid common to C# and android. I am using 32feet bluetooth library for C#. The errors i am facing are 1) My logcat shows this debug log Error while doing socket.connect()1 java.io.IOException: File descriptor in bad state Message: File descriptor in bad state Localized Message: File descriptor in bad state Received : Testing Connection Count of Thread is : 1 2) When i try to send something via C# app the second time, this exception is thrown: A first chance exception of type 'System.InvalidOperationException' occurred in System.dll System.InvalidOperationException: BeginConnect cannot be called while another asynchronous operation is in progress on the same Socket. at System.Net.Sockets.Socket.DoBeginConnect(EndPoint endPointSnapshot, SocketAddress socketAddress, LazyAsyncResult asyncResult) at System.Net.Sockets.Socket.BeginConnect(EndPoint remoteEP, AsyncCallback callback, Object state) at InTheHand.Net.Bluetooth.Msft.SocketBluetoothClient.BeginConnect(BluetoothEndPoint remoteEP, AsyncCallback requestCallback, Object state) at InTheHand.Net.Sockets.BluetoothClient.BeginConnect(BluetoothEndPoint remoteEP, AsyncCallback requestCallback, Object state) at InTheHand.Net.Sockets.BluetoothClient.BeginConnect(BluetoothAddress address, Guid service, AsyncCallback requestCallback, Object state) at BTSyncClient.Form1.connect() in c:\users\----\documents\visual studio 2010\Projects\TestClient\TestClient\Form1.cs:line 154 I only know android application programming and i designed the C# by learning bit and pieces.

• Manually setting breakpoints in WinDBG

  - by chris

  I am trying to examine the assembly for an executable using WinDBG, but I am having a hard time getting to it. I want to set a breakpoint at the first instruction in my program, but when I try to do that manually (using the address of the module), WinDBG tells me that it is "unable to insert breakpoint" at that location due to an "Invalid access to memory location." I notice that when I create a breakpoint through the source code GUI, the address is not the same as the first part of my module (In my example: "Win32FileOpen", a simple program I wrote.) Is there a header of some sort that requires adding an offset to the address of my module? In another question, I saw the suggestion: "I would attempt to calculate the breakpoint address as: Module start + code start + code offset" but was unsure where to obtain those values. Can somebody please elaborate on this? The reason I don't just use the source GUI is that I want to be able to do this with a program that I may not have the source/symbols for. If there is an easier way to immediately start working with the executable I open, please let me know. (e.g. Opening an .exe Olly immediately shows me the assembly for that .exe, searching for referenced strings gives me results from that module, etc. WinDBG seems to start me off in ntdll.dll, which is not usually useful for me.) 0:000> lm start end module name 00000000`00130000 00000000`0014b000 Win32FileOpen C (private pdb symbols) C:\cfinley\code\Win32FileOpen\Debug\Win32FileOpen.pdb 00000000`73bd0000 00000000`73c2c000 wow64win (deferred) 00000000`73c30000 00000000`73c6f000 wow64 (deferred) 00000000`74fe0000 00000000`74fe8000 wow64cpu (deferred) 00000000`77750000 00000000`778f9000 ntdll (pdb symbols) c:\symbols\mssymbols\ntdll.pdb\15EB43E23B12409C84E3CC7635BAF5A32\ntdll.pdb 00000000`77930000 00000000`77ab0000 ntdll32 (deferred) 0:000> bu 00000000`00130000 0:000> bl 0 e x86 00000000`001413a0 0001 (0001) 0:**** Win32FileOpen!main <-- One that is generated via GUI 1 e x86 00000000`00130000 0001 (0001) 0:**** Win32FileOpen!__ImageBase <-- One I tried to set manually 0:000> g Unable to insert breakpoint 1 at 00000000`00130000, Win32 error 0n998 "Invalid access to memory location." bp1 at 00000000`00130000 failed WaitForEvent failed ntdll!LdrpDoDebuggerBreak+0x31: 00000000`777fcb61 eb00 jmp ntdll!LdrpDoDebuggerBreak+0x33 (00000000`777fcb63)

• iPhone how to enable or disable UITabBar

  - by Dean Wagstaff

  I have a simple app with a tab bar which based upon user input disables one or more of the bar items. I understand I need to use a UITabBarDelegate which I have tried to use. However when I call the delegate method I get an uncaught exception error [NSObject doesNotRecognizeSelector]. I am not sure I am doing this all right or that I haven't missed something. Any suggestions. What I have now is the following: WMViewController.h import define kHundreds 0 @interface WMViewController : UIViewController { } @end WMViewController.m import "WMViewController.h" import "MLDTabBarControllerAppDelegate.h" @implementation WMViewController (IBAction)finishWizard{ MLDTabBarControllerAppDelegate *appDelegate = (MLDTabBarControllerAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate setAvailabilityTabIndex:0 Enable:TRUE]; } MLDTabBarControllerAppDelegate.h import @interface MLDTabBarControllerAppDelegate : NSObject { } (void) setAvailabilityTabIndex: (NSInteger) index Enable: (BOOL) enable; @end MLDTabBarControllerAppDelegate.m import "MLDTabBarControllerApplicationDelegate.h" import "MyListDietAppDelegate.h" @implementation MLDTabBarControllerAppDelegate (void) setAvailabilityTabIndex: (NSInteger) index Enable: (BOOL) enable { UITabBarController *controller = (UITabBarController *)[[[MyOrganizerAppDelegate getTabBarController] viewControllers ] objectAtIndex:index]; [[controller tabBarItem] setEnabled:enable]; } @end I get what appear to be a good controller object but crash on the [[controller tabBarItem]setEnabled:enable]; What am I missing... Any suggestions Thanks,

• Using Crypt function Python 3.3.2

  - by adampski

  In Windows and Python version 3.3.2, I try and call the python module like so: hash2 = crypt(word, salt) I import it at the top of my program like so: from crypt import * The result I get is the following: Traceback (most recent call last): File "C:\none\of\your\business\adams.py", line 10, in <module> from crypt import * File "C:\Python33\lib\crypt.py", line 3, in <module> import _crypt ImportError: No module named '_crypt' However, when I execute the same file adams.py in Ubuntu, with Python 2.7.3, it executes perfectly - no errors. I tried the following to resolve the issue for my Windows & Python 3.3.2 (though I'm sure the OS isn't the issue, the Python version or my use of syntax is the issue): Rename the directory in the Python33 directory from Lib to lib Rename the crypt.py in lib to _crypt.py. However, it turns out the entire crypt.py module depends on an external module called _crypt.py too. Browsed internet to download anything remotely appropriate to resemble _crypt.py It's not Python, right? It's me...(?) I'm using syntaxes to import and use external modules that are acceptable in 2.7.3, but not in 3.3.2. Or have I found a bug in 3.3.2?

• iPhone UnitTesting UITextField value and otest error 133

  - by Justin Galzic

  Are UITextFields not meant to be part of the LogicTests and instead part of the ApplicationTest target? I have a factory class that is responsible for creating and returning an (iPhone) UITextField and I'm trying to unit test it. It is part of my Logic Test target and when I try to build and run the tests, I get a build error about: /Developer/Tools/RunPlatformUnitTests.include:451:0 Test rig '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.2.sdk/ 'Developer/usr/bin/otest' exited abnormally with code 133 (it may have crashed). In the build window, this points to the following line in: "RunPlatformUnitTests.include" RPUTIFail ${LINENO} "Test rig '${TEST_RIG}' exited abnormally with code ${TEST_RIG_RESULT} (it may have crashed)." My unit test looks like this: #import <SenTestingKit/SenTestingKit.h> #import <UIKit/UIKit.h> // Test-subject headers. #import "TextFieldFactory.h" @interface TextFieldFactoryTests : SenTestCase { } @end @implementation TextFieldFactoryTests #pragma mark Test Setup/teardown - (void) setUp { NSLog(@"%@ setUp", self.name); } - (void) tearDown { NSLog(@"%@ tearDown", self.name); } #pragma mark Tests - (void) testUITextField_NotASecureField { NSLog(@"%@ start", self.name); UITextField *textField = [TextFieldFactory createTextField:YES]; NSLog(@"%@ end", self.name); } The class I'm trying to test: // Header file #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> @interface TextFieldFactory : NSObject { } +(UITextField *)createTextField:(BOOL)isSecureField; @end // Implementation file #import "TextFieldFactory.h" @implementation TextFieldFactory +(UITextField *)createTextField:(BOOL)isSecureField { // x,y,z,w are constants declared else where UITextField *textField = [[[UITextField alloc] initWithFrame:CGRectMake(x, y, z, w)] autorelease]; // some initialization code return textField; } @end

• OCUnit & NSBundle

  - by kpower

  I created OCUnit test in concordance with "iPhone Development Guide". Here is the class I want to test: // myClass.h #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> @interface myClass : NSObject { UIImage *image; } @property (readonly) UIImage *image; - (id)initWithIndex:(NSUInteger)aIndex; @end // myClass.m #import "myClass.m" @implementation myClass @synthesize image; - (id)init { return [self initWithIndex:0]; } - (id)initWithIndex:(NSUInteger)aIndex { if ((self = [super init])) { NSString *name = [[NSString alloc] initWithFormat:@"image_%i", aIndex]; NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"png"]; image = [[UIImage alloc] initWithContentsOfFile:path]; if (nil == image) { @throw [NSException exceptionWithName:@"imageNotFound" reason:[NSString stringWithFormat:@"Image (%@) with path \"%@\" for current index (%i) wasn't found.", [name autorelease], path, aIndex] userInfo:nil]; } [path release]; } return self; } - (void)dealloc { [image release]; [super dealloc]; } @end And my unit-test (LogicTests target): // myLogic.m #import <SenTestingKit/SenTestingKit.h> #import <UIKit/UIKit.h> #import "myClass.h" @interface myLogic : SenTestCase { } - (void)testTemp; @end @implementation myLogic - (void)testTemp { STAssertNoThrow([[myClass alloc] initWithIndex:0], "myClass initialization error"); } @end All necessary frameworks, "myClass.m" and images added to target. But on build I have an error: [[myClass alloc] initWithIndex:0] raised Image (image_0) with path \"(null)\" for current index (0) wasn't found.. myClass initialization error This code (initialization) works fine in application itself (main target) and later displays correct image. I've also checked my project folder (build/Debug-iphonesimulator/LogicTests.octest/) - there are LogicTests, Info.plist and necessary image files (image_0.png is one of them). What's wrong?

• Create Zip File In Windows and Extract Zip File In Linux

  - by Yan Cheng CHEOK

  I had created a zip file (together with directory) under Windows as follow : package sandbox; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; /** * * @author yan-cheng.cheok */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // These are the files to include in the ZIP file String[] filenames = new String[]{"MyDirectory" + File.separator + "MyFile.txt"}; // Create a buffer for reading the files byte[] buf = new byte[1024]; try { // Create the ZIP file String outFilename = "outfile.zip"; ZipOutputStream out = new ZipOutputStream(new FileOutputStream(outFilename)); // Compress the files for (int i=0; i<filenames.length; i++) { FileInputStream in = new FileInputStream(filenames[i]); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(filenames[i])); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file out.close(); } catch (IOException e) { e.printStackTrace(); } } } The newly created zip file can be extracted without problem under Windows, by using http://www.exampledepot.com/egs/java.util.zip/GetZip.html However, I realize if I extract the newly created zip file under Linux, using http://www.exampledepot.com/egs/java.util.zip/GetZip.html, I will get a file named "MyDirectory\MyFile.txt" instead of MyFile.txt being placed under folder MyDirectory. I try to solve the problem by changing the zip file creation code to String[] filenames = new String[]{"MyDirectory" + "/" + "MyFile.txt"}; But, is this an eligible solution, by hard-coded the seperator? Will it work under Mac OS? (I do not have a Mac to try out)

• FTP server output and accents

  I've written this little test class to connect up to an FTP server. import java.io.BufferedInputStream; import java.io.IOException; import java.io.InputStream; import java.net.MalformedURLException; import java.net.URL; import java.net.URLConnection; public class FTPTest { public static void main(String[] args) { URL url = null; try { url = new URL("ftp://anonymous:[email protected]"); } catch (MalformedURLException e) { e.printStackTrace(); } URLConnection conn = null; try { conn = url.openConnection(); } catch (IOException e) { e.printStackTrace(); } InputStream in = null; try { in = conn.getInputStream(); } catch (IOException e) { e.printStackTrace(); } BufferedInputStream bin = new BufferedInputStream(in); int b; try { while ((b = bin.read()) != -1) { char c = (char) b; System.out.print("" + (char) b); } } catch (IOException e) { e.printStackTrace(); } } } Here's the output: -rw-r--r-- 1 ftp ftp 4700 Apr 30 2007 premier.java -rw-r--r-- 1 ftp ftp 88576 Oct 23 2007 Serie1_1.doc -rw-r--r-- 1 ftp ftp 1401 Nov 21 2006 tp20061121.txt drwxr-xr-x 1 ftp ftp 0 Apr 23 20:04 répertoire Notice the name of the directory at the end of the list. There should be an "é" (e with acute accent) instead of the double character "é". This reminds me of an issue encountered previously with JSF where there was a mix-up between standards. I have little experience with character-encoding though so I'm not sure what's happening. I'm supposing that the server output is in ASCII so how do I adapt the output so it appears correctly in the console?

• Maven Eclipse plugin and classpath issues in Eclipse

  - by subferno

  I am using Eclipse 3.51, Maven 2.0.9, Java 1.4, with the Maven Eclipse plugin 2.7 with WTP 2.0 (not m2Eclipse). I have a flat multi module project that is set up as follows (module Parent with the parent pom, module A and B is dependent on C). Importing the four modules in for the first time will show compile errors as expected since I have not ran the eclipse plugin. With my local repository empty, running eclipse clean will resolve all compile errors and dependencies within the my local workspace. If I were to make some minor code changes to module B and run the eclipse plugin again, compile errors would show up in module A and B. Compile errors about classes that cannot be found. Its like module C is no longer in the classpath for A and B to see. I look at the .classpath file and its definitely looking at the right modules in the Eclipse workspace. If I delete the maven repository and do the eclipse clean again, the compile errors about unresolved classes are fixed. Also, if I run the eclpse clean command with the useProjectReferences flag to false and then rerun it with true, Eclipse would rebuild my workspace and the errors will go away. Whats going on?

• How do I correctly install dulwich to get hg-git working on Cygwin?

  - by Erik Vold

  I have a similar issue as in this issue, but in my case I am trying to use cygwin. First I followed the instructions here, and I ran: $ easy_install hg-git The I created ~/.hgrc, with: [extensions] hgext.bookmarks = hggit = Then when I typed 'hg' at a command prompt, I'd see: "* failed to import extension hggit: No module named hggit" So I did a search for "hggit" and found /cygdrive/c/Python26/Lib/site-packages/hg_git-0.2.1-py2.6.egg/hggit, so I updated .hgrc: [extensions] hgext.bookmarks = hggit = /cygdrive/c/Python26/Lib/site-packages/hg_git-0.2.1-py2.6.egg/hggit Then when I type 'hg' I get "No module named dulwich.errors" If you read this question, it's the same problem. In python shell I cannot import dulwich: >>> import dulwich Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named dulwich I checked out my easy-install.pth and it does contain the dulwich egg: import sys; sys.__plen = len(sys.path) ./hg_git-0.2.1-py2.6.egg ./dulwich-0.5.0-py2.6-win32.egg import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new) So how can I fix this so that import dulwich works, which should fix my problem using hg-git I assume..

• Perl OO frameworks and program design - Moose and Conway's inside-out objects (Class::Std)

  - by Emmel

  This is more of a use-case type of question... but also generic enough to be more broadly applicable: In short, I'm working on a module that's more or less a command-line wrapper; OO naturally. Without going into too many details (unless someone wants them), there isn't a crazy amount of complexity to the system, but it did feel natural to have three or four objects in this framework. Finally, it's an open source thing I'll put out there, rather than a module with a few developers in the same firm working on it. First I implemented the OO using Class::Std, because Perl Best Practices (Conway, 2005) made a good argument for why to use inside-out objects. Full control over what attributes get accessed and so on, proper encapsulation, etc. Also his design is surprisingly simple and clever. I liked it, but then noticed that no one really uses this; in fact it seems Conway himself doesn't really recommend this anymore? So I moved to everyone's favorite, Moose. It's easy to use, although way way overkill feature-wise for what I want to do. The big, major downside is: it's got a slew of module dependencies that force users of my module to download them all. A minor downside is it's got way more functionality than I really need. What are recommendations? Inconvenience fellow developers by forcing them to use a possibly-obsolete module, or force every user of the module to download Moose and all its dependencies? Is there a third option for a proper Perl OO framework that's popular but neither of these two?

• Custom Java ListCellRenderer - Can't click JCheckBox

  - by Spencer

  Made a custom ListCellRenderer: import java.awt.Component; import javax.swing.JCheckBox; import javax.swing.JLabel; import javax.swing.JList; import javax.swing.JPanel; import javax.swing.ListCellRenderer; /** * * @author Spencer */ public class TaskRenderer implements ListCellRenderer { private Task task; private JPanel panel = new JPanel(); private JCheckBox checkbox = new JCheckBox(); private JLabel label = new JLabel(); public TaskRenderer() { panel.add(checkbox); panel.add(label); } public Component getListCellRendererComponent( JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { task = (Task) value; label.setText(task.getName()); return panel; } } Have a JList with each cell in it rendered using the above class, but the checkboxes in the panels for each cell cannot be clicked. Thought it had to do with it not getting focus. Any ideas? Thanks, Spencer

Why? I suppose that it's because I do not see frame from the run method of the Thread.

• Prevent Ninject from calling Initialize multiple times when binding to several interfaces

  - by Ahe

  Hi We have a concrete singleton service which implements Ninject.IInitializable and 2 interfaces. Problem is that services Initialize-methdod is called 2 times, when only one is desired. We are using .NET 3.5 and Ninject 2.0.0.0. Is there a pattern in Ninject prevent this from happening. Neither of the interfaces implement Ninject.IInitializable. the service class is: public class ConcreteService : IService1, IService2, Ninject.IInitializable { public void Initialize() { // This is called twice! } } And module looks like this: public class ServiceModule : NinjectModule { public override void Load() { this.Singleton<Iservice1, Iservice2, ConcreteService>(); } } where Singleton is an extension method defined like this: public static void Singleton<K, T>(this NinjectModule module) where T : K { module.Bind<K>().To<T>().InSingletonScope(); } public static void Singleton<K, L, T>(this NinjectModule module) where T : K, L { Singleton<K, T>(module); module.Bind<L>().ToMethod(n => n.Kernel.Get<T>()); } Of course we could add bool initialized-member to ConcreteService and initialize only when it is false, but it seems quite a bit of a hack. And it would require repeating the same logic in every service that implements two or more interfaces. Thanks for all the answers! I learned something from all of them! (I am having a hard time to decide which one mark correct). We ended up creating IActivable interface and extending ninject kernel (it also removed nicely code level dependencies to ninject, allthough attributes still remain).

• Is there a better way to refresh WebView?

  - by cdg

  Hi all. Ok. I have looked EVERYWHERE and my little brain just can't understand a better way to refresh an activity. Any suggestions that I can understand would be great. :) Here is the java code: package com.dge.dges; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.webkit.WebView; import android.widget.Button; public class dgeActivity extends Activity { WebView mWebView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mWebView = (WebView) findViewById(R.id.webview); mWebView.getSettings(); mWebView.loadUrl("http://www.websitehere.php"); Button newButton = (Button)findViewById(R.id.new_button); newButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Intent intent = new Intent(dgeActivity.this, dgeActivity.class); startActivity(intent); } }); } } And here is the main.xml <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#000000" > <WebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="wrap_content" android:scrollbars="none" /> <Button android:id="@+id/new_button" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:text="Refresh" /> </RelativeLayout> I don't like the idea of just re-stacking activity after activity.
