• Hudson fails to use unix user/group to do authentication

  - by Kane

  I'm trying to use unix user/group database as security realm of hudson. The linux server is using NIS for user management. My account could login the hudson server via ssh. And the hudson server is running by user 'hudson' that is also a member of group 'shadow', so hudson could read /etc/shadow. And I tested the configuration using 'test' button, hudson tells me it works well. But I can't use my unix account and password to login the hudson sever. And I found below java exception in the log of hudson, Jan 12, 2011 8:23:42 AM hudson.security.AuthenticationProcessingFilter2 onUnsuccessfulAuthentication INFO: Login attempt failed org.acegisecurity.BadCredentialsException: pam_authenticate failed : Authentication failure; nested exception is org.jvnet.libpam.PAMException: pam_authenticate failed : Authentication failure at hudson.security.PAMSecurityRealm$PAMAuthenticationProvider.authenticate(PAMSecurityRealm.java:100) at org.acegisecurity.providers.ProviderManager.doAuthentication(ProviderManager.java:195) at org.acegisecurity.AbstractAuthenticationManager.authenticate(AbstractAuthenticationManager.java:45) at org.acegisecurity.ui.webapp.AuthenticationProcessingFilter.attemptAuthentication(AuthenticationProcessingFilter.java:71) at org.acegisecurity.ui.AbstractProcessingFilter.doFilter(AbstractProcessingFilter.java:252) at hudson.security.ChainedServletFilter$1.doFilter(ChainedServletFilter.java:87) at org.acegisecurity.ui.basicauth.BasicProcessingFilter.doFilter(BasicProcessingFilter.java:173) at hudson.security.ChainedServletFilter$1.doFilter(ChainedServletFilter.java:87) at org.acegisecurity.context.HttpSessionContextIntegrationFilter.doFilter(HttpSessionContextIntegrationFilter.java:249) at hudson.security.HttpSessionContextIntegrationFilter2.doFilter(HttpSessionContextIntegrationFilter2.java:66) at hudson.security.ChainedServletFilter$1.doFilter(ChainedServletFilter.java:87) at hudson.security.ChainedServletFilter.doFilter(ChainedServletFilter.java:76) at hudson.security.HudsonFilter.doFilter(HudsonFilter.java:164) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at winstone.RequestDispatcher.forward(RequestDispatcher.java:333) at winstone.RequestHandlerThread.processRequest(RequestHandlerThread.java:244) at winstone.RequestHandlerThread.run(RequestHandlerThread.java:150) at java.lang.Thread.run(Thread.java:595) Caused by: org.jvnet.libpam.PAMException: pam_authenticate failed : Authentication failure at org.jvnet.libpam.PAM.check(PAM.java:105) at org.jvnet.libpam.PAM.authenticate(PAM.java:123) at hudson.security.PAMSecurityRealm$PAMAuthenticationProvider.authenticate(PAMSecurityRealm.java:90) ... 18 more

• [java bean]hibernate Session breaks a java bean?

  - by blow

  Hi all, i have a simple JPanel bean in my projects, now i want to drag my panel bean class into my jframe. My panel bean class is like this: public class BeanPanel extends javax.swing.JPanel { /** Creates new form BeanPanel */ public BeanPanel () { initComponents(); Session session=HibernateUtil.getSessionFactory().openSession(); } This code seem to break the bean: Session session=HibernateUtil.getSessionFactory().openSession(); When i try to drag the class into my JFrame bean i had this error message: This component cannot be instantiated. Please make sure it is a JavaBeans Component If i comment it all works fine. What is the reason of this? Thanks.

• Java: library that does nice formatted log outputs

  - by WizardOfOdds

  I cannot find back a library that allowed to format log output statements in a much nicer way than what is usually seen. One of the feature I remember is that it could 'offset' the log message depending on the 'nestedness' of where the log statement was occuring. That is, instead of this: DEBUG | DefaultBeanDefinitionDocumentReader.java| 86 | Loading bean definitions DEBUG | AbstractAutowireCapableBeanFactory.java| 411 | Finished creating instance of bean 'MS-SQL' DEBUG | DefaultSingletonBeanRegistry.java| 213 | Creating shared instance of singleton bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java| 383 | Creating instance of bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java| 459 | Eagerly caching bean 'MySQL' to allow for resolving potential circular references DEBUG | AutowireCapableBeanFactory.java| 789 | Another debug message It would shows something like this: DEBUG | DefaultBeanDefinitionDocumentReader.java| 86 | Loading bean definitions DEBUG | AbstractAutowireCapableBeanFactory.java | 411 | Finished creating instance of bean 'MS-SQL' DEBUG | DefaultSingletonBeanRegistry.java | 213 | Creating shared instance of singleton bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java | 383 | Creating instance of bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java | 459 | |__ Eagerly caching bean 'MySQL' to allow for resolving potential circular references DEBUG | AutowireCapableBeanFactory.java | 789 | |__ Another debug message This is an example I just made up (VeryLongCamelCaseClassNamesNotMine). But I remember seeing such cleanly formatted log output and they were really much nicer than anything I had seen before and, in addition to being just plain nicer, they were also easier to read for they reproduced some of the logical organization of the code. Yet I cannot find anymore what that library was. I'm pretty sure it was fully compatible with log4j or sl4j.

• MKL Accelerated Math Libraries for Java...

  - by Kaopua

  I've looked at the related threads on StackOverflow and Googled with not much luck. I'm also very new to Java (I'm coming from a C# and .NET background) so please bear with me. There is so much available in the Java world it's pretty overwhelming. I'm starting on a new Java-on-Linux project that requires some heavy and highly repetitious numerical calculations (i.e. statistics, FFT, Linear Algebra, Matrices, etc.). So maximizing the performance of the mathematical operations is a requirement, as is ensuring the math is correct. So hence I have an interest in finding a Java library that perhaps leverages native acceleration such as MKL, and is proven (so commercial options are definitely a possibility here). In the .NET space there are highly optimized and MKL accelerated commercial Mathematical libraries such as Centerspace NMath and Extreme Optimization. Is there anything comparable in Java? Most of the math libraries I have found for Java either do not seem to be actively maintained (such as Colt) or do not appear to leverage MKL or other native acceleration (such as Apache Commons Math). I have considered trying to leverage MKL directly from Java myself (e.g. JNI), but me being new to Java (let alone interoperating between Java and native libraries) it seemed smarter finding a Java library that has already done this correctly, efficiently, and is proven. Again I apologize if I am mistaken or misguided (even in regarding any libraries I've mentioned) and my ignorance of the Java offerings. It's a whole new world for me coming from the heavily commercialized Microsoft stock so I could easily be mistaken on where to look and regarding the Java libraries I've mentioned. I would greatly appreciate any help or advice.

• Use a non-coalescing parser in Axis2

  - by Nathan

  Does anyone know how I can get Axis2 to use a non-coalescing XMLStreamReader when it parses a SOAP message? I am writing code that reads a large base64 binary text element. Coalescing is the default behaviour, and this causes the default XMLStreamReader to load the entire text into memory rather than returning multiple CHARACTERS events. The upshot of this is that I run out of heap space when running the following code: reader = element.getTextAsStream( true ); The OutOfMemory error occurs in com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next: java.lang.OutOfMemoryError: Java heap space at com.sun.org.apache.xerces.internal.util.XMLStringBuffer.append(XMLStringBuffer.java:208) at com.sun.org.apache.xerces.internal.util.XMLStringBuffer.append(XMLStringBuffer.java:226) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanContent(XMLDocumentFragmentScannerImpl.java:1552) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:2864) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:607) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSDocumentScannerImpl.java:116) at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:558) at org.apache.axiom.util.stax.wrapper.XMLStreamReaderWrapper.next(XMLStreamReaderWrapper.java:225) at org.apache.axiom.util.stax.dialect.DisallowDoctypeDeclStreamReaderWrapper.next(DisallowDoctypeDeclStreamReaderWrapper.java:34) at org.apache.axiom.util.stax.wrapper.XMLStreamReaderWrapper.next(XMLStreamReaderWrapper.java:225) at org.apache.axiom.util.stax.dialect.SJSXPStreamReaderWrapper.next(SJSXPStreamReaderWrapper.java:138) at org.apache.axiom.om.impl.builder.StAXOMBuilder.parserNext(StAXOMBuilder.java:668) at org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java:214) at org.apache.axiom.om.impl.llom.SwitchingWrapper.updateNextNode(SwitchingWrapper.java:1098) at org.apache.axiom.om.impl.llom.SwitchingWrapper.<init>(SwitchingWrapper.java:198) at org.apache.axiom.om.impl.llom.OMStAXWrapper.<init>(OMStAXWrapper.java:73) at org.apache.axiom.om.impl.llom.OMContainerHelper.getXMLStreamReader(OMContainerHelper.java:67) at org.apache.axiom.om.impl.llom.OMContainerHelper.getXMLStreamReader(OMContainerHelper.java:40) at org.apache.axiom.om.impl.llom.OMElementImpl.getXMLStreamReader(OMElementImpl.java:790) at org.apache.axiom.om.impl.llom.OMElementImplUtil.getTextAsStream(OMElementImplUtil.java:114) at org.apache.axiom.om.impl.llom.OMElementImpl.getTextAsStream(OMElementImpl.java:826) at org.example.UploadFileParser.invokeBusinessLogic(UploadFileParser.java:160)

• Can Scala be considered a functional superset of Java?

  - by Giorgio

  Apart from the differences in syntax, can Scala be considered a superset of Java that adds the functional paradigm to the object-oriented paradigm? Or are there any major features in Java for which there is no direct Scala equivalent? With major features I mean program constructs that would force me to heavily rewrite / restructure my code, e.g., if I had to port a Java program to Scala. Or can I expect that, given a Java program, I can port it to Scala almost line-by-line?

• Setting httponly in JSESSIONID cookie (Java EE 5)

  - by mythandros

  I'm trying to set the httponly flag on the JSESSIONID cookie. I'm working in Java EE 5, however, and can't use setHttpOnly(). First I tried to create my own JSESSIONID cookie from within the servlet's doPost() by using response.setHeader(). When that didn't work, I tried response.addHeader(). That didn't work either. Then, I learned that the servlet handled converting the session into a JSESSIONID cookie and inserting it into the http header so if I want to play with that cookie, I'll have to write a filter. I wrote a filter and played with setHeader()/addHeader() there, again to no avail. Then, I learned that there's some flush/close action going on in the response object before it gets to the filter so if I want to manipulate the data, I need to extend HttpServletResponseWrapper and pass that to filterChain.doFilter(). This is done but I'm still not getting results. Clearly I'm doing something wrong but I don't know what. I'm not sure if this is at all relevant to the question at hand but no html document is being returned by the servlet to the browser. All that's really happening is that some objects are being populated and returned to a JSP document. I've sort of assumed that The Session object is turned into a JSESSIONID cookie and wrapped -- along with the objects added to the request -- in an http header before being sent to the browser. I'd be happy to post some code but I want to rule out the possibility that my difficulties stem from a misunderstanding of the theory first.

• Showing ImageView next to TextView in a ListView

  - by KDEx

  So I have a listview that is displaying correctly. When the item is "turned on" the text is white and when it's turned off it's grey. That part all functions great. However when I add the ImageView into the mix I get a null pointer exception. I don't understand why. I've tried using bitmaps as well and get the same problem. Here is some code: @Override public void bindView(View view, Context context, Cursor cursor) { TextView rRule = (TextView) view.findViewById(R.id.rule_text); TextView rType = (TextView) view.findViewById(R.id.rule_type);

• Java SE 7u10: Enhanced Security Features and Support for New Platforms

  - by Tori Wieldt

  On December 11, 2012 Oracle released Java SE 7 Update 10 (Java SE 7u10). This release includes enhanced security features and support for new platforms. Enhanced Security Features The JDK 7u10 release includes the following security enhancements: The ability to disable any Java application from running in the browser. This mode can be set in the Java Control Panel or (on Microsoft Windows platform only) using a command-line install argument. The ability to select the desired level of security for unsigned applets, Java Web Start applications, and embedded JavaFX applications that run in a browser. Four levels of security are supported. This feature can be set in the Java Control Panel or (on Microsoft Windows platform only) using a command-line install argument. New dialogs to warn you when the JRE is insecure (either expired or below the security baseline) and needs to be updated. For more information, read Henrik Stahl's blog Oracle JDK 7u10 Released with New Security and the documentation Setting the Level of Security for the Java Client. New Supported Platforms Java SE 7 Update 10 (Java SE 7u10) supports Windows 8 Desktop Mode1 with IE 10, and Mac OS 10.8.? For more information, refer to the Oracle Certified System Configurations page.  Download and Release Notes Java SE 7u10 is available on OTN Download Page.

Everything about java is correctly installed but when I try to run java ("java -version" forexample) I get this error : Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I don't think this is a java centered problem, Out of memory for sure. I contacted the vps admin, but he says everything is fine, you have 2gb ram, expandable to 4gb! I did a bit search on the subject, here is my BEANS file (numbers converted to humanredable form using a script). By the way do JVM heap memory allocs count on kmemsize or privvmpages ? How much ram does that configuration allows me to allocate with jvm for a single process? resource held maxheld barrier limit failcnt kmemsize 2.25 mb 2.35 mb 13.71 mb 14.10 mb 0 lockedpages 0 0 1024.00 kb 1024.00 kb 0 privvmpages 20.54 mb 21.33 mb 256.00 mb 272.00 mb 156 shmpages 5.00 mb 5.00 mb 84.00 mb 84.00 mb 0 numproc 13 14 240 240 0 physpages 9.36 mb 9.45 mb 0 MAX_ULONG 0 vmguarpages 0 0 132.00 mb MAX_ULONG 0 oomguarpages 9.36 mb 9.45 mb MAX_ULONG MAX_ULONG 0 numtcpsock 3 3 360 360 0 numflock 3 3 188 206 0 numpty 2 2 16 16 0 numsiginfo 0 1 256 256 0 tcpsndbuf 69.17 kb 69.17 kb 1.64 mb 2.58 mb 0 tcprcvbuf 48.00 kb 48.00 kb 1.64 mb 2.58 mb 0 othersockbuf 6.80 kb 6.80 kb 1.07 mb 2.00 mb 0 dgramrcvbuf 0.00 kb 0.00 kb 256.00 kb 256.00 kb 0 numothersock 9 10 360 360 0 dcachesize 0.00 kb 0.00 kb 3.25 mb 3.46 mb 0 numfile 704 746 9312 9312 0 numiptent 10 10 128 128 0 Thanks in advance!

• Java ME SDK 3.0.5 Integrated with NetBeans 7.1.1

  - by SungmoonCho

  NetBeans 7.1.1 now integrates Java ME SDK 3.0.5, so you do not have to download them separately. Java ME SDK was packaged in NetBeans Mobility Pack, a mobile application development toolkit for NetBeans. Therefore, Java ME SDK is no longer a separate menu on NetBeans. For those who have not downloaded Java ME SDK yet, please simply visit NetBeans website and download the latest version. For those who already have Java ME SDK integrated with NetBeans 7.1 or earlier, and want to update NetBeans IDE to 7.1.1, don't worry. They can co-exist. To use NetBeans plug-ins such as Device Selector, profiler, and Internationalization Resource Manager, you have to install "Java ME SDK Tools" from NetBeans. Here is how. 1.  Go to "Tools - Plug-ins" from NetBeans menu. You can find all the plug-ins you can install into NetBeans. Locate "Java ME SDK Tools" from the list. 2. Follow the instruction to install Java ME SDK Plug-ins. 3. Once completed, you will see new menu options. For example, you can find Device Selector under Tools - Java ME. (If you used old version of Java ME, you will notice that there is not 'Java ME' menu any more. This is because all the sub-menus were integrated into appropriate places in NetBeans.) There is one thing to keep in mind; Since NetBeans 7.1.1 already includes Java ME SDK 3.0.5 and Java ME SDK 3.0.5 plug-ins must be installed through NetBeans plug-in menu, you should not download Java ME SDK 3.0.5 separately and try to integrate it with NetBeans. This may cause issues.
