  • Where to put default-servlet-handler in Spring MVC configuration

    - by gigadot
    In my web.xml, the default servlet mapping, i.e. /, is mapped to Spring dispatcher. In my Spring dispatcher configuration, I have DefaultAnnotationHandlerMapping, ControllerClassNameHandlerMapping and AnnotationMethodHandlerAdapter which allows me to map url to controllers either by its class name or its @Requestmapping annotation. However, there are some static resources under the web root which I also want spring dispatcher to serve using default servlet. According to Spring documentation, this can be done using <mvc:default-servlet-handler/> tag. In the configuration below, there are 4 candidate locations that I marked which are possible to insert this tag. Inserting the tag in different location causes the dispatcher to behave differently as following : Case 1 : If I insert it at location 1, the dispatcher will no longer be able to handle mapping by the @RequestMapping and controller class name but it will be serving the static content normally. Cas 2, 3 : It will be able to handle mapping by the @RequestMapping and controller class name as well as serving the static content if other mapping cannot be done successfully. Case 4 : It will not be able to serve the static contents. Therefore, Case 2 and 3 are desirable .According to Spring documentation, this tag configures a handler which precedence order is given to lowest so why the position matters? and Which is the best position to put this tag? <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <context:annotation-config/> <context:component-scan base-package="webapp.controller"/> <!-- Location 1 --> <!-- Enable annotation-based controllers using @Controller annotations --> <bean id="annotationUrlMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <!-- Location 2 --> <bean id="controllerClassNameHandlerMapping" class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/> <!-- Location 3 --> <bean id="annotationMethodHandlerAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> <!-- Location 4 --> <mvc:default-servlet-handler/> <!-- All views are JSPs loaded from /WEB-INF/jsp --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> </beans>

  • Copy object into another

    - by EugeneP
    Is there an easy way how to achieve this: MyObj : (id, name); MyObj myObj_1 = new MyObj(1, "Name 1"); MyObj myObj_2 = new MyObj(2, "Name 2"); instead of myObj_2.setName(myObj_1.getName()) etc do something as following: myObj_2.copyFrom(myObj_1) so that they are different instances, but have equal properties.

  • Hot deploy not longer working on JBoss

    - by Bernhard V
    Hi! I've got a pretty annoying problem with my JBoss AS 4.2.3 GA. Until recently everything was running fine, but now the hot deploy feature is now longer working. And -- as always -- I don't know what I did to cause this behaviour. My projects are built with Maven. I've cleaned every target directory, installed the projects and then deployed them to the server. So the sources in Eclipse and the deployed projects on the server should be identical. Inside a method I've added a simple System.out.println("test"); statement and -- BANG! -- I get the following error: Do you know a way out of my trouble?

  • Better way to set unix permissions when deploying war file

    - by Chris G
    We have a vendor application where we download their updates and deploy a war file. We are deploying the war file on a unix application server running oracle application server 9i. I believe when we deploy the war file, we remove the previous install and then deploy the new war file. When we deploy the war file, sometimes we have to manually set the unix file permissions for the class and other files. We do this so all the unix user ids can run the processes they need. Is there a better way to do this?

  • Debugging JSR 168 Portlet with spring, eclipse & pluto.

    - by mikep
    I am trying to set up a development environment to test Spring Portlet MVC for development of JSR 168 conforming portlets. I have the latest STS installed, which included Spring 2.5 and Eclipse (Catalina). This has been my environment to develop with Spring MVC, and that works fine using Apache as a local server for debugging. I found some instructions on the Pluto portal site on using Pluto as a remote debugging host for portlets. I have implemented those instructions. I am sending Eclipse into debug mode by right clicking on one of the JSPs and going into "debug as". My problem is that when I log into Pluto, it is not sending me into debug mode. I am seeing the default Pluto page as opposed to my portlet. My portlet has not been installed onto Pluto, and the instructions do not seem to require the portlet to be installed. To help, I have a screen shot at http://www.ceruleaninc.ca/pluto%5Fproblem.jpg, showing the following: Eclipse showing the remote debugging to localhost:8000 Tomcat showing the "Listening for transport dt_socket at address: 8000 The Catalina.bat jpda start command The Pluto Portal screen after log in Thanks much! I would welcome any advice on approaches to debugging portlets. I am not tied to pluto. There does seem to be a lack of detailed instructions on this topic.

  • Quartz Cron Trigger with Spring - triggering new cron before last ended

    - by Trick
    Simple question, I think. I have org.springframework.scheduling.quartz.CronTriggerBean triggering one job once a day. Because this method can last a long time (over 24 hours), will the next day at the same time a new job be executed if the last one is not ended yet? If yes - is it possible to turn off executing new jobs until the last one is finished? My method is trans-coding videos and some days there a lot of videos and could last long.

  • Remove Duplicates from List of HashMap Entries

    - by HonorGod
    I have a List<HashMap<String,Object>> which represents a database where each list record is a database row. I have 10 columns in my database. There are several rows where the values of 2 particular columns are equals. I need to remove the duplicates from the list after the list is updated with all the rows from database. What is the efficient way? FYI - I am not able to do distinct while querying the database, because the GroupName is added at a later stage to the Map after the database is loaded. And since Id column is not primary key, once you add GroupName to the Map. You will have duplicates based on Id + GroupName combination! Hope my question makes sense. Let me know if we need more clarification.

  • How to manage orientation lock in android?

    - by pixel
    I want to create checkbox in my preference Activity that allows user to toggle orientation change. In similar questions people write only about complete orientation lock (by overriding onConfigurationChanged method or adding configChanges in AndroidManifest.xml) or orientation enforcing ( by setRequestedOrientation ). Is there a way to toggle orientation lock?

  • Google App Engine - Uploading blobs and authentication

    - by Keyur
    (I tried asking this on the GAE forums but didn't get an answer so am trying it here.) Currently to upload blobs, the app engine's blob store service creates a unique one- time URL that a user can post blobs to. My requirement is that I only want authenticated / authorized users to post blobs in my application. I can achieve this currently if the page that includes the multipart form to upload blobs is in my application. However, I am looking to providing a "REST API" for my users to upload their blobs. While it is true that the one-time nature of the upload URL mitigates the chances of rogue use but it's still possible. I was wondering if there is anyone on the app engine team here that can consider a feature where developers can register an upload listener. (Or if there is already a way, I'll be all ears). A standard servlet filter could also potentially do the job. This will give us an opportunity to authenticate / validate / decorate requests before the request gets forwarded to the blob store service. Thanks, Keyur

  • Setting up ehcache replication - what multicast settings do I need?

    - by Darren Greaves
    I am trying to set up ehcache replication as documented here: http://ehcache.sourceforge.net/EhcacheUserGuide.html#id.s22.2 This is on a Windows machine but will ultimately run on Solaris in production. The instructions say to set up a provider as follows: <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory" properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1, multicastGroupPort=4446, timeToLive=32"/> And a listener like this: <cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" properties="hostName=localhost, port=40001, socketTimeoutMillis=2000"/> My questions are: Are the multicast IP address and port arbitrary (I know the address has to live within a specific range but do they have to be specific numbers)? Do they need to be set up in some way by our system administrator (I am on an office network)? I want to test it locally so am running two separate tomcat instances with the above config. What do I need to change in each one? I know both the listeners can't listen on the same port - but what about the provider? Also, are the listener ports arbitrary too? I've tried setting it up as above but in my testing the caches don't appear to be replicated - the value added in one tomcat's cache is not present in the other cache. Is there anything I can do to debug this situation (other than packet sniffing)? Thanks in advance for any help, been tearing my hair out over this one!

  • Thoughts on using Alpha Five v10 with Codeless AJAX for building an AJAX database app in a short amo

    - by william Hunter
    I need to build an AJAX application against our MS SQL Server database for my company. the app has to have user permissions and reporting and is pretty complex. I am really under the gun in terms of time. The company that I work for needs the app for an important project launch. A colleague/friend of mine in a different company recommended that I look at a product from Alpha Software called Alpha Five v10 with Codeless AJAX. He has told me that he has used it extensively and that it saves him a "serious boat load of time" and he says that he has not run into limitations because you can also write your own JavaScript or you wire in jQuery. Before I commit to Alpha Five v10, I would like to get any other opinions? Thanks. Norman Stern. Chicago

  • How do you use stereotype annotations in Spring 2.5.x?

    - by grigory
    When moving to Spring 2.5.x I found that it adds more stereotype annotations (on top of @Repository from 2.0): @Component, @Service and @Controller. How do you use them? Do you rely on implicit Spring support or you define custom stereotype specific functions/aspects/features? Or is it predominately for marking beans (compile time, conceptual, etc.)?

  • Invert bitmap colors

    - by Alex Orlov
    I have the following problem. I have a charting program, and it's design is black, but the charts (that I get from the server as images) are light (it actually uses only 5 colors: red, green, white, black and gray). To fit with the design inversion does a good job, the only problem is that red and green are inverted also (green - pink, red - green). Is there a way to invert everything except those 2 colors, or a way to repaint those colors after inversion? And how costly are those operations (since I get the chart updates pretty often)? Thanks in advance :) UPDATE I tried replacing colors with setPixel method in a loop for(int x = 0 ;x < chart.getWidth();x++) { for(int y = 0;y < chart.getHeight();y++) { final int replacement = getColorReplacement(chart.getPixel(x, y)); if(replacement != 0) { chart.setPixel(x, y, replacement); } } } Unfortunetely, the method takes too long (~650ms), is there a faster way to do it, and will setPixels() method work faster?

  • Hibernate save() and transaction rollback

    - by Marco
    Hi, In Hibernate when i save() an object in a transaction, and then i rollback it, the saved object still remains in the DB. It's strange because this issue doesn't happen with the update() or delete() method, just with save(). Here is the code i'm using: DbEntity dbEntity = getDbEntity(); HibernateUtil.beginTransaction(); Session session = HibernateUtil.getCurrentSession(); session.save(dbEntity); HibernateUtil.rollbackTransaction(); And here is the HibernateUtil class (just the involved functions, i guarantee the getSessionFactory() method works well - there is an Interceptor handler, but it doesn't matter now): private static final ThreadLocal<Session> threadSession = new ThreadLocal<Session>(); private static final ThreadLocal<Transaction> threadTransaction = new ThreadLocal<Transaction>(); /** * Retrieves the current Session local to the thread. * <p/> * If no Session is open, opens a new Session for the running thread. * * @return Session */ public static Session getCurrentSession() throws HibernateException { Session s = (Session) threadSession.get(); try { if (s == null) { log.debug("Opening new Session for this thread."); if (getInterceptor() != null) { log.debug("Using interceptor: " + getInterceptor().getClass()); s = getSessionFactory().openSession(getInterceptor()); } else { s = getSessionFactory().openSession(); } threadSession.set(s); } } catch (HibernateException ex) { throw new HibernateException(ex); } return s; } /** * Start a new database transaction. */ public static void beginTransaction() throws HibernateException { Transaction tx = (Transaction) threadTransaction.get(); try { if (tx == null) { log.debug("Starting new database transaction in this thread."); tx = getCurrentSession().beginTransaction(); threadTransaction.set(tx); } } catch (HibernateException ex) { throw new HibernateException(ex); } } /** * Rollback the database transaction. */ public static void rollbackTransaction() throws HibernateException { Transaction tx = (Transaction) threadTransaction.get(); try { threadTransaction.set(null); if ( tx != null && !tx.wasCommitted() && !tx.wasRolledBack() ) { log.debug("Tyring to rollback database transaction of this thread."); tx.rollback(); } } catch (HibernateException ex) { throw new HibernateException(ex); } finally { closeSession(); } } Thanks
