  • How to get icons for entities from eclipse?

    - by fastcodejava
    I am writing an eclipse plugin. How do I get the various images from eclipse library? So I don't have have keep a local set of images for the standard entities, e.g classes, interfaces, junits, etc. EDIT : I used PlatformUI.getWorkbench().getSharedImages().getImage(ISharedImages.IMG_OBJ_FILE) from the article : http://www.eclipse.org/articles/Article-Using%20Images%20In%20Eclipse/Using%20Images%20In%20Eclipse.html. That did not work.

  • Hibernate custom join clause on association

    - by myso
    I would like to associate 2 entities using hibernate annotations with a custom join clause. The clause is on the usual FK/PK equality, but also where the FK is null. In SQL this would be something like: join b on a.id = b.a_id or b.a_id is null From what I have read I should use the @WhereJoinTable annotation on the owner entity, but I'm puzzled about how I specify this condition...especially the first part of it - referring to the joining entity's id. Does anyone have an example?

  • Testing code that uses SoftReference<T>

    - by bmargulies
    To get any code with SoftReference<T> to be fully tested, one must come up with some way to test the 'yup, it's been nulled' case. One might more or less mock this by using a 'for-test' code path to force the reference to be null, but that won't manage the queue exactly as the GC does. I wonder if anyone out can share experience in setting up a repeatable, controlled, environment, in which the GC is, in fact, provoked into collecting and nulling?

  • Using custom detectors with FindBugs Maven plugin

    - by Lóránt Pintér
    I have a nice JAR of some custom FindBugs detectors I'd like to use with the FindBugs Maven plugin. There is a way to do this with the plugin via the <pluginList> configuration parameter, but that only accepts local files, URLs, or resources. The only way I found for doing so is to somehow copy my JAR to a local file (maybe via the Dependency plugin) and then configure the FindBugs plugin something like this: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>findbugs-maven-plugin</artifactId> <version>2.3.1</version> <configuration> <pluginList>${project.build.directory}/my-detectors.jar</pluginList> </configuration> </plugin> But this is not very flexible. Is there a way to use Maven's dependency management features together with FindBugs' plugins? I'd like to use something like this: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>findbugs-maven-plugin</artifactId> <dependencies> <dependency> <groupId>com.lptr.findbugs</groupId> <artifactId>my-detectors</artifactId> <version>1.0</version> </dependency> </dependencies> </plugin> ...but this simply overrides the core FindBugs detectors.

  • SWT: cleaning up before application exit

    - by Alexey Romanov
    What is the best way for an SWT application to clean up resources before application exit? I see two options: 1) Add a DisposeListener to main window (or better, to the Display). Will it get run if an uncaught exception happens? 2) Use a shutdown hook. Any problems to be aware of there which aren't mentioned in Design of the Shutdown Hooks API?

  • Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML

    - by phpwns
    Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML tables) generated with Javascript? An embarrassingly simple, though workable solution using Crowbar: <?php function get_html($url) // $url must be urlencode(d) { $context = stream_context_create(array( 'http' => array('timeout' => 120) // HTTP timeout in seconds )); $html = substr(file_get_contents('http://127.0.0.1:10000/?url=' . $url . '&delay=3000&view=browser', 0, $context), 730, -32); // substr removes HTML from the Crowbar web service, returning only the $url HTML return $html; } ?> The advantage to using Crowbar is that the tables will be rendered (and accessible) thanks to the headless mozilla-based browser. The problem, of course, is being dependent on on an external web service, especially given that SIMILE seems to undergo regular server maintenance. :( A pure php solution would be nice, but any functional (and reliable) alternatives would be great.

  • Reflection in unit tests for checking code coverage

    - by Gary
    Here's the scenario. I have VO (Value Objects) or DTO objects that are just containers for data. When I take those and split them apart for saving into a DB that (for lots of reasons) doesn't map to the VO's elegantly, I want to test to see if each field is successfully being created in the database and successfully read back in to rebuild the VO. Is there a way I can test that my tests cover every field in the VO? I had an idea about using reflection to iterate through the fields of the VO's as part of the solution, but maybe you guys have solved the problem before? I want this test to fail when I add fields in the VO, and don't remember to add checks for it in my tests.

  • Extracting startup errors from Spring contexts

    - by sehugg
    Consider the following output from a Tomcat server under Eclipse: INFO: Initializing Coyote HTTP/1.1 on http-8080 INFO: Initialization processed in 634 ms INFO: Starting service Catalina INFO: Starting Servlet Engine: Apache Tomcat/6.0.20 SEVERE: Error listenerStart SEVERE: Context [/MyServlet] startup failed due to previous errors I would like to figure out what exception caused "Error listenerStart", but Spring seems to be preventing me from finding the error via Eclipse. I'd love to start Catalina manually, but that doesn't seem to do anything. What's the best way to find the hidden exception? I'm not afraid to use torture methods.

  • Keeping messages in queue in case of receiver crash

    - by John Doe
    Hi, We've a Spring JMS message listener container for receiving messages asynchronously. Using DefaultMessageListenerContainer and in sessionTransacted mode. I understand being in sessionTransacted mode means in case of an exception the message will be put back into the queue. But how can I make sure the message won't be deleted from the queue even if the receiver (which is picked the message) crashes or just the machine running it looses power? At first I thought CLIENT_ACKNOWLEDGE acknowledge mode should save me, but apparently it's not the case, Spring calls .acknowledge() no matter what. So here's my question, how can I guarantee the delivery? Using a custom MessageListenerContainer? Using a transaction manager?

  • Programatically Add a AnnotationSessionFactoryBean

    - by user146714
    Hi, I have a class that implements BeanDefinitionRegistryPostProcessor. I am trying to add an AnnotationSessionFactoryBean to my Spring Context in either postProcessBeanFactory or postProcessBeanDefinitionRegistry. I need to do this programatically so that I can configure the object at runtime. I am trying to do: @Override public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry bdr) throws BeansException { RootBeanDefinition bd = new RootBeanDefinition( AnnotationSessionFactoryBean.class); // fails here.. can not cast AnnotationSessionFactoryBean asfb = (AnnotationSessionFactoryBean)bd; bdr.registerBeanDefinition("sessionFactory", asfb); thanks for your help --updated with solution: had to do a: GenericBeanDefinition bd = new GenericBeanDefinition(); bd.setBeanClass(AnnotationSessionFactoryBean.class); bd.getPropertyValues().add("dataSource", dataSource); bdr.registerBeanDefinition("sessionFactory", bd);

  • Determining if a coordinate is on a line

    - by TGCBraun
    I´m coding a little app that allows the user to draw multiple shapes and then remove or resize them. It´s working perfectly on rectangles and ovals, but I´m having issues with lines. Here´s a method that I wrote to find if the clicked spot on the screen is part of a specific line: public boolean containsLocation(int x, int y) { int m = (getY2() - getY()) / (getX2() - getX()); int b = getY() - (m * getX()); if (y == (m * x) + b) { return true; } return false; I´m using the famous y = mx + b formula and replacing y and x to find if the clicked spot is part of the line. The problem is when I click on the screen to remove the line, it only works if I click on the very fist coordinate (x,y) where the line starts. Nothing happens when I click anywhere else along the line. Can anyone shed a light on what I´m doing wrong? Thanks a lot.

  • Running multiple jvms for different applications in same machine

    - by Rajesh
    We are getting frequent out of memory errors in our dev. machines We are running webshpere, eclipse, soap UI and maven in it. Our server gets down due to this "out of memory errors" when we restart our applications in websphere 2/3 times, We already increased the virtual memory setting in wesphere to 1GB. So what i did was copied the jre we use in eclipse and maven folders so that each of these uses individual jvms. But the performance of websphere is same. 2/3 restarts and out of memory errors. Is there any may of making eclipse and maven use different jvms other than websphere's?

  • Jboss Seam Booking Example Extract Shared Libs From Ear

    - by michael lucas
    Example Booking Application, which JBoss Seam is shipped with, build into EAR file of about 7 MB. That's pretty much if you consider deploying this package to a remote Jboss server and possibly redeploying it package many times during your regular work. Lib files like richfaces and jsf-facelet make the lion's share of that EAR size. Why can't we just extract lib files into jboss-web.deployer directory on JBoss 4.2.0 GA server?

  • getResourceAsStream returns HttpInputStream not of the entire file

    - by khue
    Hi, I am having a web application with an applet which will copy a file packed witht the applet to the client machine. When I deploy it to webserver and use: InputStream in = getClass().getResourceAsStream("filename") ; The in.available() always return a size of 8192 bytes for every file I tried, which means the file is corrupted when it is copied to the client computer. The InputStream is of type HttpInputStream (sun.net.protocol.http.HttpUrlConnection$httpInputStream). But while I test applet in applet viewer, the files are copied fine, with the InputStream returned is of type BufferedInputStream, which has the file's byte sizes. I guess that when getResourceStream in file system the BufferedInputStream will be used and when at http protocol, HttpInputStream will be used. How will I copy the file completely, is there a size limited for HttpInputStream? Thanks a lot.

  • Where to handle fatal exceptions

    - by Stephen Swensen
    I am considering a design where all fatal exceptions will be handled using a custom UncaughtExceptionHandler in a Swing application. This will include unanticipated RuntimeExceptions but also custom exceptions which are thrown when critical resources are unavailable or otherwise fail (e.g. a settings file not found, or a server communication error). The UncaughtExceptionHandler will do different things depending on the specific custom exception (and one thing for all the unanticipated), but in all cases the application will show the user an error message and exit. The alternative would be to keep the UncaughtExceptionHandler for all unanticipated exceptions, but handle all other fatal scenarios close to their origin. Is the design I'm considering sound, or should I use the alternative?
