  • How do you get the selected value of a spinner -- Android

    - by Matthew Hall
    Hi everyone, I'm trying to get the selected items string out of a spinner. So far I've got this: bundle.putString(ListDbAdapter.DB_PRI, v.getText().toString()); This doesn'y work and gives a casting exception (I thought you could cast a view to a widget that inherits it... obviously not!). So how do you get the selected value of a spinner

  • Configure WebLogic MDB to listen to Foreing AMQ Server

    - by eliel.lobo
    I'm trying to create an MDB(EJB 3.0) on WebLogic 10.3.5. to listen to a Queue in an external AMQ server. but after much work and combination of tutorials i get the followin error when deployin on WwebLogic. [EJB:015027]The Message-Driven EJB is transactional but JMS connection factory referenced by the JNDI name: ActiveMQXAConnectionFactory is not a JMS XA connection factory. Here is a brief of the work i have done: I have added the corresponding libraries to my WLS classpath (following thos tuturial http://amadei.com.br/blog/index.php/connecting-weblogic-and-activemq) and I have created the corresponding JMS Modules as indicated in the tutorial. As connection factory I have used ActiveMQConnectionFactory initially and ActiveMQXAConnectionFactory later, I also ignome the jms. notation an just put plain names as testQueue. Then create a simple MDB whit the following structure. I explicitly defined "connectionFactoryJndiName" property because otherwise it assumes a WebLogic connection factory which is not found an then raises an error. @MessageDriven( activationConfig = { @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"), @ActivationConfigProperty(propertyName = "destination", propertyValue = "testQueue"), @ActivationConfigProperty(propertyName = "connectionFactoryJndiName", propertyValue = "ActiveMQXAConnectionFactory") }, mappedName = "testQueue") public class ROMELReceiver implements MessageListener { /** * Default constructor. */ public ROMELReceiver() { // TODO Auto-generated constructor stub } /** * @see MessageListener#onMessage(Message) */ public void onMessage(Message message) { System.out.println("Message received"); } } At this point I'm stuck with the error mentioned above. Even though I use ActiveMQXAConnectionFactory instead of simply ActiveMQConnectionFactory, JNDI resources tree in web logic server shows org.apache.activemq.ActiveMQConnectionFactory as class for my configured connection factory. am i missing something? or is this just a completely wrong way to connect WebLogic whith AMQ? Thanks in advance.

  • Should I use a collection here?

    - by Eva
    So I have code set up like this: public interface IInterface { public void setField(Object field); } public abstract class AbstractClass extends JPanel implements IInterface { private Object field_; public void setField(Object field) { field_ = field; } } public class ClassA extends AbstractClass { public ClassA() { // unique ClassA constructor stuff } public Dimension getPreferredSize() { return new Dimension(1, 1); } } public class ClassB extends AbstractClass { public ClassB() { // unique ClassB constructor stuff } public Dimension getPreferredSize() { return new Dimension(42, 42); } } public class ConsumerA { public ConsumerA(Collection<AbstractClass> collection) { for (AbstractClass abstractClass : collection) { abstractClass.setField(this); abstractClass.repaint(); } } } All hunky-dory so far, until public class ConsumerB { // Option 1 public ConsumerB(ClassA a, ClassB b) { methodThatOnlyTakesA(a); methodThatOnlyTakesB(b); } // Option 2 public ConsumerB(Collection<AbstractClass> collection) { for (IInterface i : collection) { if (i instanceof ClassA) { methodThatOnlyTakesA((ClassA) i); else if (i instanceof ClassB) { methodThatOnlyTakesB((ClassB) i); } } } } public class UsingOption1 { public static void main(String[] args) { ClassA a = new ClassA(); ClassB b = new ClassB(); Collection<AbstractClass> collection = Arrays.asList(a, b); ConsumerA consumerA = new ConsumerA(collection); ConsumerB consumerB = new ConsumerB(a, b); } } public class UsingOption2 { public static void main(String[] args) { Collection<AbstractClass> collection = Arrays.asList(new ClassA(), new ClassB()); ConsumerA = new ConsumerA(collection); ConsumerB = new ConsumerB(collection); } } With a lot more classes extending AbstractClass, both options get unwieldly. Option1 would make the constructor of ConsumerB really long. Also UsingOption1 would get long too. Option2 would have way more if statements than I feel comfortable with. Is there a viable Option3? If it helps, ClassA and ClassB have all the same methods, they're just implemented differently. Thanks for slogging through my code!

  • Value object getter

    - by sarah xia
    Hi, I've got a value object, which stores info for example amount. The getAmount() getter returns amount in cents. However in various places, we need to get amount in dollar. There are 2 approaches I can think of: write a convert method and place it in a utility class. add a getAmountInDollar() getter in the value object. I prefer the second approach. What do you think? What are pros and cons of both approaches?

  • Register all GUI components as Observers or pass current object to next object as a constructor argu

    - by Jack
    First, I'd like to say that I think this is a common issue and there may be a simple or common solution that I am unaware of. Many have probably encountered a similar problem. Thanks for reading. I am creating a GUI where each component needs to communicate (or at least be updated) by multiple other components. Currently, I'm using a Singleton class to accomplish this goal. Each GUI component gets the instance of the singleton and registers itself. When updates need to be made, the singleton can call public methods in the registered class. I think this is similar to an Observer pattern, but the singleton has more control. Currently, the program is set up something like this: class c1 { CommClass cc; c1() { cc = CommClass.getCommClass(); cc.registerC1( this ); C2 c2 = new c2(); } } class c2 { CommClass cc; c2() { cc = CommClass.getCommClass(); cc.registerC2( this ); C3 c3 = new c3(); } } class c3 { CommClass cc; c3() { cc = CommClass.getCommClass(); cc.registerC3( this ); C4 c4 = new c4(); } } etc. Unfortunately, the singleton class keeps growing larger as more communication is required between the components. I was wondering if it's a good idea to instead of using this singleton, pass the higher order GUI components as arguments in the constructors of each GUI component: class c1 { c1() { C2 c2 = new c2( this ); } } class c2 { C1 c1; c2( C1 c1 ) { this.c1 = c1 C3 c3 = new c3( c1, this ); } } class c3 { C1 c1; C2 c2; c3( C1 c1, C2 c2 ) { this.c1 = c1; this.c2 = c2; C4 c4 = new c4( c1, c2, this ); } } etc. The second version relies less on the CommClass, but it's still very messy as the private member variables increase in number and the constructors grow in length. Each class contains GUI components that need to communicate through CommClass, but I can't think of a good way to do it. If this seems strange or horribly inefficient, please describe some method of communication between classes that will continue to work as the project grows. Also, if this doesn't make any sense to anyone, I'll try to give actual code snippets in the future and think of a better way to ask the question. Thanks.

  • Duplicate column name by JPA with @ElementCollection and @Inheritance

    - by gerry
    I've created the following scenario: @javax.persistence.Entity @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) public class MyEntity implements Serializable{ @Id @GeneratedValue protected Long id; ... @ElementCollection @CollectionTable(name="ENTITY_PARAMS") @MapKeyColumn (name = "ENTITY_KEY") @Column(name = "ENTITY_VALUE") protected Map<String, String> parameters; ... } As well as: @javax.persistence.Entity public class Sensor extends MyEntity{ @Id @GeneratedValue protected Long id; ... // so here "protected Map<String, String> parameters;" is inherited !!!! ... } So running this example, no tables are created and i get the following message: WARNUNG: Got SQLException executing statement "CREATE TABLE ENTITY_PARAMS (Entity_ID BIGINT NOT NULL, ENTITY_VALUE VARCHAR(255), ENTITY_KEY VARCHAR(255), Sensor_ID BIGINT NOT NULL, ENTITY_VALUE VARCHAR(255))": com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Duplicate column name 'ENTITY_VALUE' I also tried overriding the attributes on the Sensor class... @AttributeOverrides({ @AttributeOverride(name = "ENTITY_KEY", column = @Column(name = "SENSOR_KEY")), @AttributeOverride(name = "ENTITY_VALUE", column = @Column(name = "SENSOR_VALUE")) }) ... but the same error. Can anybody help me?

  • How to figure out which jars are needed?

    - by Ari
    How can I systematically determine which jars I'll need, and thus should include in my pom.xml file (I'm using maven as my project management tool)? When learning spring, to keep things simple, added all the jars (even the ones I never used) to the classpath. Right now for the most part, I'm guessing which jars to include. For example, I know in my spring configuration file, I have: <tx:annotation-driven /> <context:annotation-config /> <aop:aspectj-autoproxy /> So, I guess I'll need: spring-context-x.x.x.jar, spring-tx-x.x.x.jar, spring-aop-x.x.x.jar Thanks.

  • EJB3 Caching Instance Variables

    - by Justin
    Hi, I've noticed some strange code on a project I am working on - its a SLSB EJB3, and it uses a private instance variable to maintain a cache of data (it even calls it dataCache or something), with a getter/setter. For EJB2 and bellow, this was a typical EJB antipattern - SLSBs are not meant to retain state in between invocations, theres no guarantee you'll see the same data on a subsequent invocation. One of my colleagues said maybe its ok in EJB3 (we don't have much EJB3 experience), but still, its a Stateless Session Bean - why is it trying to maintain state, this doesn't make sense. Can anyone confirm if this is still a bad idea in EJB3 land, or if somehow it is ok? Thanks if you can help, Justin

  • Reloading of persisted entity

    - by Udi
    I'm using OpenJPA in my application as a JPA vendor. The question is theoretical or conceptual: Is there any way to tell an entity manager to load an entity from the DB rather than from it's cache? The problematic scenario: EM1.persist(Entity1) EM2.merge(Entity1) EM1.find(Entity1) <--- Entity1 is the cached version rather than the merged one.. Any elegant way to do it? I really don't want to call em.refresh(entity).

  • Spring Weblfow 2 - Double Submit

    - by John W.
    Hello All, I am investigating a possible issue with double submits and I am looking at the possibilty of a double submit from a webflow execution. I have read many times that webflow will handle double submits, there are plenty references here. However I then came across I a forum response on the spring source forums contradicting what I read saying, SWF synchronizes on the conversation. Only one request will be processed at a time per conversation. Take note that if you're using snapshots, then it's possible repeatedly clicking on the submit button will generate a second request. I would recommend setting history to invalidate or discard in the transition from your view-state. We do have snapshots enabled but the book notes that using snapshots actually allows to solve the double submits. Does anyone have any insight on this? Thanks.

  • Regarding Multiple Tab-Class

    - by Christine
    Hi! I've problem regarding GUI with one Menu and one Order Class. I've created a variable to store how many items have been selected in the Menu Class. private int totalSelected; The var totalSelected is live updated. It can be changed anytime depending on actionPerformed() function.(Exp: totalSelected will add up all the selected items) In the Order Class, how can I access to the live update variable totalSelected in order to retrieve the live update value? When I invoke getTotalSelected() function inside the Menu Class, I will only obtain a 0 value. Thanks for your help ^^!

  • JSP Document/JSPX: what determines how space/linebreaks are removed in the output?

    - by NoozNooz42
    I've got a "JSP Document" ("JSP in XML") nicely formatted and when the webpage is generated and sent to the user, some linebreaks are removed. Now the really weird part: apparently the "main" .jsp always gets all its linebreak removed but for any subsequent .jsp included from the main .jsp, linebreaks seems to be randomly removed (some are there, others aren't). For example, if I'm looking at the webpage served from Firefox and ask to "view source", I get to see what is generated. So, what determines when/how linebreaks are kept/removed? This is just an example I made up... Can you force a .jsp to serve this: <body><div id="page"><div id="header"><div class="title">... or this: <body> <div id="page"> <div id="header"> <div class="title">... ? I take it that linebreaks are removed to save on bandwidth, but what if I want to keep them? And what if I want to keep the same XML indentation as in my .jsp file? Is this doable?

  • Drools Rules: How can I use a method on "when" section?

    - by manoelhc
    Hi, I need to execute a method on "when" section of a DSLR file and I´m not sure if it´s possible. Example: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(isInAgeRange("30-100")==true) Reminder(clickPercentual >= 10) User(haveAtLeastOptIns("1,2,3,4") == true) then $reminder.setPriority(1);update($reminder); end (note: isInAgeRange() and haveAtLeastOptIns() are methods of User) I tried with eval() and no errors appeared, but it didn´t execute. Like this: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(eval($user.isInAgeRange("30-100")==true)) Reminder(clickPercentual >= 10) User(eval($user.haveAtLeastOptIns("1,2,3,4") == true)) then $reminder.setPriority(1);update($reminder); end How can I resolve this problem?

  • Alternative to DITA Open Toolkit

    - by Adam
    I'm working on a web app that will need to process DITA documents from persistent storage (likely a JCR). The DITA Open Toolkit is the only DITA implementation I'm aware of, but it requires all of your documents to exist on the filesystem. Ideally, I'd like something that works like the DITA OT, but allows you to provide a resolver (much like an XSLT URIResolver) to pull referenced content from other sources. If people have other ideas, such as using a virtual filesystem to trick the DITA OT into working, I'd love to hear those too. Thanks!

  • Persistence with Vaadin

    - by palto
    Hi I'm trying to learn vaadin. I'm really confused how to do any kind of application development with persistence because if I have a reference to my service layer objects, they get stored in session and I really don't want that. Persistence stuff just isn't serializable. My case is that I have an already made application that uses Spring and I'm creating a new UI for it with Vaadin. I can inject the spring stuff to my Vaadin application but that gets stored in the session. Any tips? By the way how do you post in the Vaadin forums? I can't find a post button or way to register :)

  • PE Header Requirements

    - by Pindatjuh
    What are the requirements of a PE file (PE/COFF)? What fields should be set, which value, at a bare minimum for enabling it to "run" on Windows (i.e. executing "ret" instruction and then close, without error). The library I am building first is the linker: Now, the problem I have is the PE file (PE/COFF). I don't know what is "required" for a PE file before it can actually execute on my platform. My testing platform is Vista. I get an error message, saying "This is not a valid Win32 executable." when I execute it by double-clicking, and I get an "Access Denied." when executing it with CLI cmd. I have two sections, .text and .data. I've implemented the PE headers as provided by several online documents, i.e. MSDN and some other thirdparty documentation. If I use a hex-editor, it looks almost like a regular PE file. I don't use any imports, nor IAT, nor any directories in the PE header. Edit: I've added an import table, still not a valid .exe-file, says my Windows. I've tried to use values which are also mentioned at the smallest PE-file guide. No luck. Really the only thing I can't seem to figure out is what is required and what isn't. Some guides tell me everything is required, whilst others say about deprications: and it can be zero. I hope this is enough information. Thank you, in advance.

  • Android: Context menu doesn't show up for ListView with members defined by LinearLayout?

    - by RandomEngy
    I've got a ListActivity and ListView and I've bound some data to it. The data shows up fine, and I've also registered a context menu for the view. When I display the list items as just a simple TextView, it works fine: <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/nametext" android:layout_width="wrap_content" android:layout_height="wrap_content"/> However when I try something a bit more complex, like show the name and a CheckBox, the menu never shows up: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/nametext" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <CheckBox android:id="@+id/namecheckbox" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> Can long-presses work on more complex elements? I'm building on 2.1.

  • Problem locating file in a classpath

    - by Gandalf StormCrow
    I'm trying to read in file content, ex : public void myMethod(){ FileInputStream fstream = new FileInputStream(fileLocation); // Get the object of DataInputStream DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String strLine; while ((strLine = br.readLine()) != null) { .... .... ..... end while end method And I have at the begining of the class body private String fileLocation; and at the end of a class I have a getter and setter for it. Now I'm trying inject this file location from spring inside bean from this class and I specify the init-method of this class. But I get error cannot find the specified file as if its not on a classpath but it is inside war file? I'm building the project with maven and I put file in src/main/resources This is the error I get when trying to read file : Error: src\main\resources\ids.txt (The system cannot find the path specified) That is when I tried this : FileInputStream fstream = new FileInputStream("src\\main\\resources\\ids.txt"); how to reference the properly from the classpath? EDIT When I edit my code according to @BalusC solution , here is how it looks but I still get null error : ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); InputStream input = classLoader.getResourceAsStream("src/main/resources/ids.txt"); // Get the object of DataInputStream BufferedReader br = new BufferedReader(new InputStreamReader(input)); String strLine; while ((strLine = br.readLine()) != null) { .... .... ..... end while end method

  • Spring MVC Best Practice Handling Unrecoverable Exceptions In Controller

    - by jboyd
    When you have a controller that does logic with services and DAO's that may throw an unrecoverable exception, what is the best practice in dealing with those method calls? Currently an app I'm working on has very lengthy try catch methods that simply err.out exception messages, this doesn't seem very robust and I think that this code smells, is there any cookie cutter best practice for handling this in spring-mvc?

  • Eclipse: How to build an executable jar with external jar?

    - by Ben
    Hi all, I am trying to build an executable jar program which depends on external jar downloaded. In my project, I included them in the build path and can be run and debug within eclipse. When I tried to export it to a jar, I can run the program but I can't when I try to press a button which includes function calls and classes from the external jar. I have edited the environment variables (Windows XP) CLASSPATH to include paths of all the external jar, but it doesn't work. A point to note is that I got compile warnings while exporting my executable jar, but it doesn't show up any description about the warnings. Would someone kindly provide a thorough guide on how to include an external jar program using eclipse? Best regards, KWAN Chiu Yin, Ben

  • Apache POI HWPF Nested Lists?

    - by Mahadevan
    Hi, I used the following code to read list structures from a word file using hwpf. My question is how to read a list structure that is nested ie a list within a list within a list and so on. if (p instanceof ListEntry) { ListEntry entry = (ListEntry) p; outText = entry.text(); outText = "<li>" + outText + "</li>"; // verifca prima e ultimo if (i > 1) { pPrev = range.getParagraph(i - 1); if (!(pPrev instanceof ListEntry)) outText = "<ul>" + outText; } if (i < nParagrafi - 1) { pNext = range.getParagraph(i + 1); if (!(pNext instanceof ListEntry)) outText = outText + "</ul>"; } if (i == nParagrafi - 1) { outText = outText + "</ul>"; }
