• 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

• Do Blob properties on entities affect query performance?

  - by Jaroslav Záruba

  Hello I'm trying to make my mind on whether to store a binary representation of an entity as its Blob property, or whether I better keep the blobs in some separate 'wrapping' class. Possible impact on memory heap and/or a query execution time are my concerns in the first case, complexity votes against the other one. I know Blobs are not indexed, i.e. index size is not what I'm worrying about. Also I assume for blobs Datastore puts defaultFetchGroup to false, but does it mean that blobs don't make a difference in queries? Regards J. Záruba

• What's a Java alternative to Google App Engine for developing iPhone Push Notification services?

  - by bpapa

  I'm a Java programmer who is working on an iPhone application. I'd like it to use Push Notification services. I originally thought I could use Google App Engine to provide the payloads to Apple, but I see now that it won't be possible because App Engine doesn't support the low-level socket programming that is needed to communicate with Apple. Are there any alternatives to Google App Engine that let me use Java? In brief, I'm wondering if there is a free hosting platform that supports Java and Socket Programming

• 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.

• Subqueries on Java GAE Datastore

  - by Dmitry

  I am trying to create a database of users with connection between users (friends list). There are 2 main tables: UserEntity (main field id) and FriendEntity with fields: - initiatorId - id of user who initiated the friendship - friendId - id of user who has been invited. Now I am trying to fetch all friends of one particular user and encountered some problems with using subqueries in JDO here. Logically the query should be something like this: SQL: SELECT * FROM UserEntity WHERE EXISTS (SELECT * FORM FriendEntity WHERE (initiatorId == UserEntity.id && friendId == userId) || (friendId == UserEntity.id && initiatorId == userId)) or SELECT * FROM UserEntity WHERE userId IN (SELECT * FROM FriendEntity WHERE initiatorId == UserEntity.id) OR userId IN (SELECT * FROM FriendEntity WHERE friendId == UserEntity.id) So to replicate the last query in JDOQL, I tried to do the following: Query friendQuery = pm.newQuery(FriendEntity.class); friendQuery.setFilter("initiatorId == uidParam"); friendQuery.setResult("friendId"); Query initiatorQuery = pm.newQuery(FriendEntity.class); initiatorQuery.setFilter("friendId == uidParam"); initiatorQuery.setResult("initiatorId"); Query query = pm.newQuery(UserEntity.class); query.setFilter("initiatorQuery.contains(id) || friendQuery.contains(id)"); query.addSubquery(initiatorQuery, "List initiatorQuery", null, "String uidParam"); query.addSubquery(friendQuery, "List friendQuery", null, "String uidParam"); query.declareParameters("String uidParam"); List<UserEntity> friends = (List<UserEntity>) query.execute(userId); In result I get the following error: Unsupported method while parsing expression. Could anyone help with this query please?

• 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)

  Hi! I'd like to use google drawVisualization API.

• How to change order in ordered+persisted collection?

  - by Jaroslav Záruba

  I just need to change order of items in a (previously persisted) ordered collection... I tried simply passing the re-arranged collection to a setter: after committing a transaction the collection is gone. Then I tried to clear() the existing collection and addAll() afterwards: clear() makes persistent manager to mark all the elements as deleted. (But obviously I would like to be able to work with the collection items in the very transaction.) (The collection is not in a default fetch group, so I tried the above also with the named fetch group added into the fetch plan. No luck.) This must be the most stupid question, but I ran out of ideas and I'm stuck here two days already. I swear I googled. :(

  Hello I want to change order of objects in a collection, and then to access+modify fields of those items. Unfortunately the items somehow become 'deleted'. This is what I do... if(someCondition) { MainEvent mainEvent = pm.getObjectById(MainEvent.class, mainEventKey); /* * events in the original order * MainEvent.subEvents field is not in default fetch group, * therefore I also tried to add the named group into the * persistenceManeger fetch plan, no difference * (mainEvent is not instance of the Event sub/class BTW) */ List<Event> subEvents = mainEvent.getSubEvents(); // re-arrange the events according to keysOrdered { Map<Key, Event> eventMap = new HashMap<Key, Event>(); for(Event event : subEvents) eventMap.put(event.getKey(), event); List<Event> eventsOrdered = new LinkedList<Event>(); for(Key eventKey : keysOrdered) eventsOrdered.add(eventMap.put(eventKey, eventMap.get(eventKey))); // } // put the re-arranged items back into the collection property { subEvents.clear(); subEvents.addAll(eventsOrdered); // } pm.makePersistent(mainEvent); eventsOrdered = subEvents; } else eventsOrdered = getEventsUsingAlternateApproach(); /* * so by now the mainEvent variable does not exist; * could it be this lead the persistence manager to mark * my events as abandoned/obsolete/invalid/deleted...? */ for(Event event : eventsOrdered) event.setDate(new Date()); // -> "Cannot write fields to a deleted object" What am I doing wrong please?

• Static files in (Java) App Engine not accessible.

  - by fiXedd

  The example documentation says that you simply need to place your files in war/ (or a subdirectory) and they should be accessible from the host (as long as they aren't JSPs or in WEB-INF). For example, if you place foo.css in war/ then you should be able to access it at http://localhost:8080/foo.css. However, this isn't working for me at all. NONE of my static files are accessible. The docs on appengine-web.xml say that you can also specifically denote certain types as static. I've tried this as well and it makes no difference. Am I missing something obvious? UPDATE: Turns out one of the mappings in my web.xml was a little too aggressive. The following was the culprit: <servlet> <servlet-name>Main</servlet-name> <servlet-class>MainServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Main</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> It seems that it was grabbing everything that wasn't grabbed be one of the other rules, which I don't understand because there was no * on the end of the url-pattern. It also seems to be directly contradictory to the documentation that says: Note: Static files, files that are served verbatim to users such as images, CSS or JavaScript, are handled separately from paths mentioned in the deployment descriptor. A request for a URL path that matches a path to a file in the WAR that's considered a static file will serve the file, regardless of servlet and filter mappings in the deployment descriptor. You can exclude files from those treated as static files using the appengine-web.xml file. So, how can I have a rule that matches the base of my domain (eg. http://www.example.com/) and still allows the static files to filter through?

• Timeout with GAE Java

  - by user242153

  Hi, I am having some issues with an app I have deployed on GAE. Specifically, I am intermittently running into the DeadlineExceededException where the server is not responding within the 30 seconds required. What is odd is that the code is not overly complex, it should run in milliseconds. My guess is that the delay is in dealing with the persistence manager and accessing the datastore. 2 questions: 1) What is the best way to track where all of the CPU time on the server is being used up? Log files do not seem helpful and to make things more complicated the code runs very fast when I am running it locally 2) Any tips / best practices in dealing with the 30 second exception? What are the biggest drivers of this? Datastore? HTTP requests / responses? Thanks

• Google search ajax api is to restrictive. Any alternatives?

  - by boomhauer

  The google search ajax api is terrific, and the .net wrapper available on codeplex makes using it from a .net project very simple. However, the api itself is crippled so that it only returns 64 results per query. Not very useful for many applications. Ignoring the likely TOS problems, are there known .net libraries that can query the root google website and scrape the results into a resultset? I'm assuming this could result in much larger result counts than the ajax version enabled.

• PHP - JSON Steam API query

  - by Hunter

  First time using "JSON" and I've just been working away at my dissertation and I'm integrating a few features from the steam API.. now I'm a little bit confused as to how to create arrays. function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530'); $test = decode_url($api); var_dump($test['response']['players'][0]['personaname']['steamid']); } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $data = file_get_contents($url); $data_output = json_decode($data, true); return $data_output; } So ea I've wrote a simple method to decode Json as I'll be doing a fair bit.. But just wondering the best way to print out arrays.. I can't for the life of me get it to print more than 1 element without it retunring an error e.g. Warning: Illegal string offset 'steamid' in /opt/lampp/htdocs/lan/lan-includes/scripts/class.steam.php on line 48 string(1) "R" So I can print one element, and if I add another it returns errors. EDIT -- Thanks for help, So this was my solution: function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530,76561197960435530'); $data = decode_url($api); foreach($data ['response']['players'] as $player) { echo "Steam id:" . $player['steamid'] . "\n"; echo "Community visibility :" . $player['communityvisibilitystate'] . "\n"; echo "Player profile" . $player['profileurl'] ."\n"; } } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $json = file_get_contents($decodeURL); $data_output = json_decode($json, true); return $data_output; } Worked this out by taking a look at the data.. and a couple json examples, this returns an array based on the Steam API URL (It works for multiple queries.... just FYI) and you can insert loops inside for items etc.. (if anyone searches for this).

• How to read an xs:any response using CXF Generated Client?

  - by mfcabrera

  Hi, When consuming a webserice with CXF 2.1.4 (the generated client) I am having problem getting the response based on the following XSD snippet in the WSDL. CXF Generates a List representing it, but when I execute the service, the response comes null. I used wireshark to what I was reciving and indeed the response XMl is coming as expected, but CXF just give me null object. Below the XSD of the response object. And <!--- chunk --> <s:element name="GestionSIIFResponse"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="GestionSIIFResult"> <s:complexType mixed="true"> <s:sequence> <s:any /> </s:sequence> </s:complexType> </s:element> </s:sequence> </s:complexType> </s:element> <!--- chunk --> And this is the response I am getting from the service: <soap:Body> <GestionSIIFResponse xmlns="http://tempuri.org/"> <GestionSIIFResult> <Siif xmlns=""> <Pagina>NUY001B</Pagina> <Exitos> <ExitoRep> <CodExito>SIL0082</CodExito> <DesExito>La transaccion se ha aplicado satisfactoriamente</DesExito> </ExitoRep> </Exitos> <InformacionCab/> <Repeticiones/> </Siif> </GestionSIIFResult> </GestionSIIFResponse>
