  • How to enable logs for sitemesh

    - by atomsfat
    Is ther any form to enable logs for sitemesh ? I already put this in the log4j configuration but it doesn't work <!-- Appenders --> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Target" value="System.out" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-5p: %c - %m%n" /> </layout> </appender> <logger name="com.opensymphony"> <level value="debug"/> </logger> <logger name="org.springframework.beans"> <level value="warn" /> </logger> <logger name="org.springframework.binding"> <level value="debug" /> </logger> <logger name="org.springframework.jdbc"> <level value="warn" /> </logger> <logger name="org.springframework.transaction"> <level value="warn" /> </logger> <logger name="org.springframework.orm"> <level value="warn" /> </logger> <logger name="org.springframework.web"> <level value="debug" /> </logger> <logger name="org.springframework.webflow"> <level value="debug" /> </logger> <!-- Root Logger --> <root> <priority value="warn" /> <appender-ref ref="console" /> </root>

  • Unable to connect on socket across different networks.

    - by maleki
    I am having trouble connecting my online application to others across another network. I am able to give them the hostAddress to connect when we are on the same network but when we are doing it across the internet the generated host address doesn't allow a connection, nor does using the ip address gotten from online sites such as whatismyip.com My biggest issue isn't debugging this code, because it works over intra-network but The server doesn't see attempts when we try to move to different networks. Also, the test ip I am using is 2222. InetAddress addr = InetAddress.getLocalHost(); String hostname = addr.getHostName(); System.out.println("Hostname: " + hostname); System.out.println("IP: " + addr.getHostAddress()); I display the host to the server when it is starting if (isClient) { System.out.println("Client Starting.."); clientSocket = new Socket(host, port_number); } else { System.out.println("Server Starting.."); echoServer = new ServerSocket(port_number); clientSocket = echoServer.accept(); System.out.println("Warning, Incoming Game.."); }

  • Working with Hibernate Queries

    - by jschoen
    I am new to hibernate queries, and trying to get a grasp on how everything works. I am using Hibernate 3 with Netbeans 6.5. I have a basic project set up and have been playing around with how to do everything. I started with essentially a search query. Where the user can enter values into one or more fields. The table would be Person with the columns first_name, middle_name, last_name for the sake of the example. The first way I found was to have a method that took firstName, middleName, and lastName as parameters: Session session = HibernateUtil.getSessionFactory().getCurrentSession(); Transaction tx = session.beginTransaction(); String query = "from Person where (first_name = :firstName or :firstName is null) "+ "and (middle_name = :middleName or :middleName is null) " "and (last_name = :lastname or :lastName is null)"; Query q = session.createQuery(query); q.setString("firstName", firstName); q.setString("middleName", middleName); q.setString("lastName", lastName); List<Person> results = (List<Person>) q.list(); This did not sit well with me, since it seemed like I should not have to write that much, and well, that I was doing it wrong. So I kept digging and found another way: Session session = HibernateUtil.getSessionFactory().getCurrentSession(); Transaction tx = session.beginTransaction(); Criteria crit = session.createCriteria(Person.class); if (firstName != null) { crit.add(Expression.ge("firstName", firstName); } if (middleName != null) { crit.add(Expression.ge("middleName", middleName); } if (lastName != null) { crit.add(Expression.ge("lastName", lastName); } List<Person> results = (List<Person>) crit.list(); So what I am trying to figure out is which way is the preferred way for this type of query? Criteria or Query? Why? I am guessing that Criteria is the preferred way and you should only use Query when you need to write it by hand for performance type reasons. Am I close?

  • Automating Portlet Deployment to WebSphere Portal Server 6.1

    - by GaZ
    I've recently started on a project to develop some portlets which will run on IBM WebSphere Portal Server 6.1. Does anyone know of any scripts, Ant tasks, Maven plugins, etc. for publishing a portlet to Portal Server? In the WebSphere Portlet Factory plugin for eclipse it is possible to "publish" a portlet project to Portal Server instance, however I'd like to know what's going on underneath the hood here (or at least how to replicate the behaviour) so that I can do it in other places (i.e. from continuous integration server). UPDATE: From what I've read it sounds like the Portlet Factory publishes using a WebSphere JMX client. Does anyone know where I can find more details on this?

  • Speed up compilation with mockito on Android

    - by pbreault
    I am currently developing an android app in eclipse using: One project for the app One project for the tests (Instrumentation and Pojo tests) In the test project, I am importing the mockito library for standard POJO testing. However, when I import the library, the compilation time skyrockets from 1 second to about 30 seconds in eclipse. The cause seems to be that the whole library is converted each time. So basically, each time a make a modification that I want to test, I have to wait 30 seconds. The only workarounds that I have found so far would be: Disable "Build Automatically" Create a project that includes only pojo tests and put mockito only there. Use another library that compiles faster (e.g. easymock) Any other suggestion?

  • Does JAXWS client make difference between an empty collection and a null collection value as returne

    - by snowflake
    Since JAX-WS rely on JAXB, and since I observed the code that unpack the XML bean in JAX-B Reference Implementation, I guess the difference is not made and that a JAXWS client always return an empty collection, even the webservice result was a null element: public T startPacking(BeanT bean, Accessor<BeanT, T> acc) throws AccessorException { T collection = acc.get(bean); if(collection==null) { collection = ClassFactory.create(implClass); if(!acc.isAdapted()) acc.set(bean,collection); } collection.clear(); return collection; } I agree that for best interoperability service contracts should be non ambiguous and avoid such differences, but it seems that the JAX-WS service I'm invoking (hosted on a Jboss server with Jbossws implementation) is returning as expected either null either empty collection (tested with SoapUI). I used for my test code generated by wsimport. Return element is defined as: @XmlElement(name = "return", nillable = true) protected List<String> _return; I even tested to change the Response class getReturn method from : public List<String> getReturn() { if (_return == null) { _return = new ArrayList<String>(); } return this._return; } to public List<String> getReturn() { return this._return; } but without success. Any helpful information/comment regarding this problem is welcome !

  • Best commercial libraries for developing NCPDP-based systems (prescription drug related)

    - by Kaveh Shahbazian
    What are (based on experiences) best commercial libraries for developing NCPDP-based systems? Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

  • android : bluetooth support

    - by Puneet kaur
    i have coded for bluetooth via defining a user task ,which will search the devices in background and set the list on foreground after finishing the search . but sometimes i am getting the data in adapter as "nodevice" "device1" "device2" ...... the problem here is why it is always filling the no device in the list and after that fill the device in list .. private BroadcastReceiver mBlueToothInfoDiscoveryListener = new BroadcastReceiver() { /** * This is an overridden function called by the framework whenever there * is some broadcast message for Bluetooth info discovery listener */ @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); // When discovery finds a device if (BluetoothDevice.ACTION_FOUND.equals(action)) { // Get the BluetoothDevice object from the Intent BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); // If it's already paired, skip it, because it's been listed // already if (device.getBondState() != BluetoothDevice.BOND_BONDED) { mNewBtDevicesArrayAdapter.add(device.getName() + "\n" + device.getAddress()); } // When discovery is finished, change the Activity title } else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) { setProgressBarIndeterminateVisibility(false); setTitle("device list"); if (mNewBtDevicesArrayAdapter.getCount() == 0) { String noDevices = "No devices found"; mNewBtDevicesArrayAdapter.add(noDevices); } } } }; but here why it is sometimes going into else option on start and filling the list with no device then to if part again ... when devices are already on .

  • @Autowire strange problem

    - by Javi
    Hello, I have a strange behaviour when autowiring I have a similar code like this one, and it works @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2{ ... } The problem is that I need that the Class2 implements an interface so I've only changed the Class2 so it's now like: @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2 implements IServiceReference<Class3, Long>{ ... } public interface IServiceReference<T, PK extends Serializable> { public T reference(PK id); } with this code I get a org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type for Class2. It seems that @ Transitional annotation is not compatible with the interface because if I remove the @Transitional annotation or the "implements IServiceReference" the problem disapears and the bean is injected (though I need to have both in this class). It also happens if I put the annotation @Transitional in the methods instead of in the Class. I use Spring 3.0.2 if this helps. Is not compatible the interface with the transactional method? May it be a Spring bug? Thanks

  • Hibernate: How do I link a subclass to its superclass?

    - by Markus
    Hey there! I'm having a little problem setting up my webshop project. Thing is, I have a User() superclass and two subclasses, PrivateUser and BusinessUser. Now, I'm not quite sure how to get my head around storing this relationship via hibernate. For the purpose of this question, the User() class contains only one field: String address; the PrivateUser contains: String firstName; and the BusinessUser contains: String CompanyName; Each field has its getter and setter. As is right now, I would only store and be able to get firstName and companyName. When I fetch a user from my DB using Hibernate I would get a PrivateUser/BusinessUser with a null address. Bottom line is, could someone point me towards a useful tutorial or better yet show a similar example code? Thanks!

  • controlling threads flow

    - by owca
    I had a task to write simple game simulating two players picking up 1-3 matches one after another until the pile is gone. I managed to do it for computer choosing random value of matches but now I'd like to go further and allow humans to play the game. Here's what I already have : http://paste.pocoo.org/show/201761/ Class Player is a computer player, and PlayerMan should be human being. Problem is, that thread of PlayerMan should wait until proper value of matches is given but I cannot make it work this way. Logic is as follows: thread runs until matches equals to zero. If player number is correct at the moment function pickMatches() is called. After decreasing number of matches on table, thread should wait and another thread should be notified. I know I must use wait() and notify() but I can't place them right. Class Shared keeps the value of current player, and also amount of matches. public void suspendThread() { suspended = true; } public void resumeThread() { suspended = false; } @Override public void run(){ int matches=1; int which = 0; int tmp=0; Shared data = this.selectData(); String name = this.returnName(); int number = this.getNumber(); while(data.getMatches() != 0){ while(!suspended){ try{ which = data.getCurrent(); if(number == which){ matches = pickMatches(); tmp = data.getMatches() - matches; data.setMatches(tmp, number); if(data.getMatches() == 0){ System.out.println(" "+ name+" takes "+matches+" matches."); System.out.println("Winner is player: "+name); stop(); } System.out.println(" "+ name+" takes "+matches+" matches."); if(number != 0){ data.setCurrent(0); } else{ data.setCurrent(1); } } this.suspendThread(); notifyAll(); wait(); }catch(InterruptedException exc) {} } } } @Override synchronized public int pickMatches(){ Scanner scanner = new Scanner(System.in); int n = 0; Shared data = this.selectData(); System.out.println("Choose amount of matches (from 1 to 3): "); if(data.getMatches() == 1){ System.out.println("There's only 1 match left !"); while(n != 1){ n = scanner.nextInt(); } } else{ do{ n = scanner.nextInt(); } while(n <= 1 && n >= 3); } return n; } }

  • Complex HashMap has different hashCode after serialization

    - by woezelmann
    I am parsing a xml file into a complex HashMap looking like this: Map<String, Map<String, EcmObject> EcmObject: public class EcmObject implements Comparable, Serializable { private final EcmObjectType type; private final String name; private final List<EcmField> fields; private final boolean pages; // getter, equals, hashCode } EcmObjectType: public enum EcmObjectType implements Serializable { FOLDER, REGISTER, DOCUMENT } EcmField public class EcmField implements Comparable, Serializable { private final EcmFieldDataType dataType; private final EcmFieldControlType controlType; private final String name; private final String dbname; private final String internalname; private final Integer length; // getter, equals, hashCode } EcmFieldDataType public enum EcmFieldDataType implements Serializable { TEXT, DATE, NUMBER, GROUP, DEC; } and EcmFieldControlType public enum EcmFieldControlType implements Serializable{ DEFAULT, CHECKBOX, LIST, DBLIST, TEXTAREA, HIERARCHY, TREE, GRID, RADIO, PAGECONTROL, STATIC; } I have overwritten all hashCode and equal methods by usind commons lang's EqualsBuilder and HashCodeBuilder. Now when I copy a A HashMap this way: Map<String, Map<String, EcmObject>> m = EcmUtil.convertXmlObjectDefsToEcmEntries(new File("e:\\objdef.xml")); Map<String, Map<String, EcmObject>> m2; System.out.println(m.hashCode()); ByteArrayOutputStream baos = new ByteArrayOutputStream(8 * 4096); ObjectOutputStream oos = new ObjectOutputStream(baos); oos.writeObject(m); ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray()); ObjectInputStream ois = new ObjectInputStream(bais); m2 = (Map<String, Map<String, EcmObject>>) ois.readObject(); System.out.println(m.hashCode()); System.out.println(m2.hashCode()); m.hashCode() is not equal to m2.hashCode() here is my output: -1639352210 -2071553208 1679930154 Another strange thing is, that eg. 10 times m has the same hashcode and suddenly on the 11th time the hashcode is different... Any ideas what this is about?

  • Vehicle 2 Vehicle Communication Questions

    - by pinnacler
    I have a rare opportunity to meet the man in charge of implementing vehicle 2 vehicle communication for the US Department of Transportation with 2 others in a few hours. Do YOU have any questions for him? I know this is a little outside the normal, but this is a 'reverse' thread and I felt he has some great knowledge on the subject that I want to share with this community. I'll post his answers later today to his questions. Ask about V2V implementation, privacy issues, use cases, or if you've thought of a great way to use V2V and want me to share it with him, he can at least think about it. He is in charge of panel that creates the standard. Or anything else...

  • Getting the OpenID URL from a Grails Controller/Service

    - by firnnauriel
    I'm using acegi 0.5.2 and enabled OpenID support. I would like to know how to accesss the URL (or username) returned by a provider (i.e. Google, Yahoo!). I can't find any docs about that so I traced the code of acegi and found this in GrailsOpenIdAuthenticationProvider: OpenIDAuthenticationToken response = (OpenIDAuthenticationToken) authentication OpenIDAuthenticationStatus status = response.status // handle the various possibilites if (status == OpenIDAuthenticationStatus.SUCCESS) { // Lookup user details UserDetails userDetails = _userDetailsService.loadUserByUsername(response.identityUrl) return new GrailsOpenIdAuthenticationToken(userDetails, response.status, response.identityUrl) } it seems that the response.identityUrl contains what i need. How can get it from a controller's (or service's) space? Thanks.

  • What is the purpose of Managers / Transactions?

    - by maxdj
    I'm building a spring application for the first time. I'm running into lots of problems with concurrency, and I suspect that there is something wrong with the way I'm managing the backend. The only difference I can see between my backend code and examples I've seen are manager classes. In my code, I have my model (managed by hibernate) and my DAOs on top of that to do CRUD/searching/etc on the models. In example code I have looked at, they never use the DAO directly. Instead, they use manager classes that call the DAOs indirectly. To me, this just seems like pointless code duplication. What are these manager classes for? I've read that they wrap my code in "transactions," but why would I want that?

  • Just curious, in NetBeans IDE 6.1 how can i get icons for my custom GUI components in the GUI editor

    - by Coder
    This is by no means really important, i was just wondering if the community knows how to put icons for my custom GUI components that show up in the NetBeans GUI designer. What i did was make several Swing components and then i use the menu options to add them to the GUI pallete, but they show up with "?" icons. It would be nice if they showed up with icons similar to swing components such as JButtons, especially for components which are subclassed for Swing components. Thanks!

  • Does overloading Grails static 'mapping' property to bolt on database objects violate DRY?

    - by mikesalera
    Does Grails static 'mapping' property in Domain classes violate DRY? Let's take a look at the canonical domain class: class Book {      Long id      String title      String isbn      Date published      Author author      static mapping = {             id generator:'hilo', params:[table:'hi_value',column:'next_value',max_lo:100]      } } or: class Book { ...         static mapping = {             id( generator:'sequence', params:[sequence_name: "book_seq"] )     } } And let us say, continuing this thought, that I have my Grails application working with HSQLDB or MySQL, but the IT department says I must use a commercial software package (written by a large corp in Redwood Shores, Calif.). Does this change make my web application nobbled in development and test environments? MySQL supports autoincrement on a primary key column but does support sequence objects, for example. Is there a cleaner way to implement this sort of 'only when in production mode' without loading up the domain class?
