  • Notification doesn't play sound or show lights even though set to

    - by robintw
    In my android application I have the following code: Notification notification = new Notification(icon, tickerText, when); context = context.getApplicationContext(); CharSequence contentTitle = "UK Radio Guide"; CharSequence contentText = title + " on " + channel_id + " at " + start; Intent notificationIntent = new Intent(context, ViewSchedules.class); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); notification.ledARGB = 0xff00ff00; notification.ledOnMS = 300; notification.ledOffMS = 1000; notification.flags |= Notification.FLAG_SHOW_LIGHTS; notification.sound = Uri.parse("android.resource://com.robinwilson.radioguide/" +R.raw.chimes); notification.vibrate = new long[] { 0, 300, 200, 300, 400, 300 }; // Actually send the notification nm.notify(0, notification); As far as I am aware, I have followed the steps in the documentation to set it to play a sound from the resources folder, and to flash the lights. However, neither of these happen. It does, however, vibrate, as instructed. Any ideas what I'm doing wrong here? I've looked through the permissions that I can give the app in the AndroidManifest.xml file, but I can't see one for letting it flash the light or make sounds.

  • Deploying spring message driven pojo on weblogic 8.1

    - by Igman
    Hello, I am trying to deploy a spring message message driven POJO on weblogic 8.1. It is a simple POJO, and it works fine being run outside of an application server, but the messages do not seem to be picked up at all. I have created empty home and remote interfaces, as well as a container bean class that contains an instance of the pojo which it gets from the application context. I then added this container bean class to the ejb-jar.xml as a . I have not been able to get the messages pick up. Does anyone have any suggestions as to what I am doing wrong? Could anyone point me to a tutorial on how to deploy a MDP? Thanks.

  • getting incorrect error even if the condition is fulfilled

    - by Tapan Desai
    I am trying to show the message based on the text shown on webpage after a particular action. If the webpage contains text MESSAGE HAS BEEN SUBMITTED SUCCESSFULLY, I want to print Message sent successfully on the screen otherwise MESSAGE SENDING FAILED. Everything is working fine but for one thing. PrintWriter printWriter = new PrintWriter(new OutputStreamWriter(sendConnection.getOutputStream()), true); printWriter.print(sendContent); printWriter.flush(); printWriter.close(); //Reading the returned web page to analyse whether the operation was sucessfull BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(sendConnection.getInputStream())); StringBuilder SendResult = new StringBuilder(); String line; while ((line = bufferedReader.readLine()) != null) { SendResult.append(line); } if (SendResult.toString().contains("MESSAGE HAS BEEN SUBMITTED SUCCESSFULLY")) { System.out.println("Message sent to " + phoneNumber + " successfully."); } else { System.err.println("Message could not send to " + phoneNumber + ". Also check login credentials"); } bufferedReader.close(); The problem is that even if the webpage contains the text MESSAGE HAS BEEN SUBMITTED SUCCESSFULLY, the condition always goes into ELSE part and show MESSAGE SENDING FAILED but thats not true because the message has been sent and i see the MESSAGE HAS BEEN SUBMITTED SUCCESSFULLY on the webpage. Can anyone tell me where am i going wrong?

  • printing out prime numbers from array

    - by landscape
    I'd like to print out all prime numbers from an array with method. I can do it with one int but don't know how to return certain numbers from array. Thanks for help! public static boolean isPrime(int [] tab) { boolean prime = true; for (int i = 3; i <= Math.sqrt(tab[i]); i += 2) if (tab[i] % i == 0) { prime = false; break; } for(int i=0; i<tab.length; i++) if (( tab[i]%2 !=0 && prime && tab[i] > 2) || tab[i] == 2) { return true; } else { return false; } //return prime; } thanks both of you. Seems like its solved: public static void isPrime(int[] tab) { for (int i = 0; i < tab.length; i++) { if (isPrimeNum(tab[i])) { System.out.println(tab[i]); } } } public static boolean isPrimeNum(int n) { boolean prime = true; for (long i = 3; i <= Math.sqrt(n); i += 2) { if (n % i == 0) { prime = false; break; } } if ((n % 2 != 0 && prime && n > 2) || n == 2) { return true; } else { return false; } }

  • spymemcached - is it possible to disable the logging system?

    - by Kico Lobo
    Hi, we are using the spymemcached memcached client but we didn't discovered how we could disable the logging system. How could we at runtime change the current logging system to something like log4j or sl4j? Notice: We could pass some VM arguments, but the problem is: we can't change our server configuration. Is it possible to pass these VM arguments at runtime? If possible, how could we do that?

  • JSF/Seam - new component instance on submit?

    - by purecharger
    And my confusion with JSF continues. This is a continuation of a question asked yesterday, but I feel it warrants a new question. I have a single seam component that expects a URL parameter to be injected for retrieving a List<String> from a method. This works perfectly on the first navigation to the page. The List is used to display many different selectOneRadio groups that populate a <h:form/>. Now on the submit, I cannot get the URL parameter to be injected or otherwise set on the component! Adding <h:inputHidden/> causes FacesExceptions to be thrown. Then I tried setting the List as an instance variable on the object, and when the subsequent call is made on the submit (which I also do not understand why that is done) I check to see if the variable is non-null: if it isn't, return it. Now I found that a new instance of the component is created on submit!!! getList() called this.toString(): .BeanAction@5fd98420 #### This is when submit is clicked getList() called this.toString(): .BeanAction@22aacbce The component has the following annotations: Stateful @Scope(ScopeType.CONVERSATION) @Name("bean") @Restrict("#{identity.loggedIn}") Can someone explain why there is a new instance of the component created? I'm really not quite sure how to go about handling this. I thought the hidden parameter would work, because that is how I would do it with straight HTML, and I'm a little surprised that its not working for JSF/Seam.

  • JDBC CommunicationsException with MySQL Database

    - by Dominik Siebel
    I'm having a little trouble with my MySQL- Connection- Pooling. This is the case: Different jobs are scheduled via Quartz. All jobs connect to different databases which works fine the whole day while the nightly scheduled jobs fail with a CommunicationsException... Quartz-Jobs: Job1 runs 0 0 6,10,14,18 * * ? Job2 runs 0 30 10,18 * * ? Job3 runs 0 0 5 * * ? As you can see the last job runs at 18 taking about 1 hour to run. The first job at 5am is the one that fails. I already tried all kinds of parameter-combinations in my resource config this is the one I am running right now: <!-- Database 1 (MySQL) --> <Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true" type="javax.sql.DataSource" name="jdbc/appDbProd" username="****" password="****" url="jdbc:mysql://127.0.0.1:3306/appDbProd?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=UTF-8" testWhileIdle="true" testOnBorrow="true" testOnReturn="true" validationQuery="SELECT 1" timeBetweenEvictionRunsMillis="1800000" /> <!-- Database 2 (MySQL) --> <Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true" type="javax.sql.DataSource" name="jdbc/prodDbCopy" username="****" password="****" url="jdbc:mysql://127.0.0.1:3306/prodDbCopy?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=UTF-8" testWhileIdle="true" testOnBorrow="true" testOnReturn="true" validationQuery="SELECT 1" timeBetweenEvictionRunsMillis="1800000" /> <!-- Database 3 (MSSQL)--> <Resource auth="Container" driverClassName="net.sourceforge.jtds.jdbc.Driver" maxActive="30" maxIdle="30" maxWait="100" removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true" name="jdbc/catalogDb" username="****" password="****" type="javax.sql.DataSource" url="jdbc:jtds:sqlserver://127.0.0.1:1433;databaseName=catalog;useNdTLMv2=false" testWhileIdle="true" testOnBorrow="true" testOnReturn="true" validationQuery="SELECT 1" timeBetweenEvictionRunsMillis="1800000" /> For obvious reasons I changed IPs, Usernames and Passwords but they can be assumed to be correct, seeing that the application runs successfully the whole day. The most annoying thing is: The first job that runs first queries Database2 successfully but fails to query Database1 for some reason (CommunicationsException): Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 39,376,539 milliseconds ago. The last packet sent successfully to the server was 39,376,539 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. Any ideas? Thanks!

  • Is using the Class instance as a Map key a best practice?

    - by Pangea
    I have read somewhere that using the class instances as below is not a good idea as they might cause memory leaks. Can someone tell me if if that is a valid statement? Or are they any problems using it this way? Map<Class<?>,String> classToInstance=new HashMap(); classToInstanceMap.put(String.class,"Test obj");

  • Powermock Slows Down Test Startup on Eclipse/Fedora 10 when on NTFS partition

    - by MrWiggles
    I've just started having a proper play with Powermock and noticed that it slows down test startup immensely. A quick look at top while it was running shows that mount.nfts-3g was taking up most of the CPU. I moved Eclipse and my source directory to ext3 partitions to see if that was a problem and the tests now startup quicker but there's still a noticeable delay. Is this normal with Powermock or am I missing something obvious?

  • Which layer implement Transaction mechanism

    - by didxga
    I knew ORM tools, such as Hibernate, have their own transaction management mechanism. We can also harness transaction by using JDBC directly. And DBMS has its transaction facilities either. I wonder that in which layer(s) the transaction is actually implemented in a J2EE application? Regards!

  • How to make a try-catch block that iterates through all objects of a list and keeps on calling a met

    - by aperson
    Basically iterating through a list and, - Invoke method on first object - Catch first exception (if any); if there are no more exceptions to catch, return normally. Otherwise, keep on invoking method until all exceptions are caught. - Move on to next object. I can iterate through each object, invoke the method, and catch one exception but I do not know how to continuously invoke the method on it and keep on catching exceptions :S Thanks :)

  • How to make Spring accept non-void setters?

    - by Chris
    Hi, I have an API which I am turning into an internal DSL. As such, most methods in my PoJos return a reference to this so that I can chain methods together declaratively as such (syntactic sugar). myComponent .setID("MyId") .setProperty("One","1") .setProperty("Two","2") .setAssociation(anotherComponent) .execute(); My API does not depend on Spring but I wish to make it 'Spring-Friendly' by being PoJo friendly with zero argument constructors, getters and setters. The problem is that Spring seems to not detect my setter methods when I have a non-void return type. The return type of this is very convenient when chaining together my commands so I don't want to destroy my programmatic API just be to compatible with Spring injection. Is there a setting in Spring to allow me to use non-void setters? Chris

  • JPA optimistic lock - setting @Version to entity class cause query to include VERSION as column

    - by masato-san
    I'm using JPA Toplink Essential, Netbean6.8, GlassFish v3 In my Entity class I added @Version annotation to enable optimistic locking at transaction commit however after I added the annotation, my query started including VERSION as column thus throwing SQL exception. None of this is mentioned in any tutorial I've seen so far. What could be wrong? Snippet public class MasatosanTest2 implements Serializable { private static final long serialVersionUID = 1L; @Id @Basic(optional = false) @Column(name = "id") private Integer id; @Column(name = "username") private String username; @Column(name = "note") private String note; //here adding Version @Version int version; query used: SELECT m FROM MasatosanTest2 m Internal Exception: com.microsoft.sqlserver.jdbc.SQLServerException Call: SELECT id, username, note, VERSION FROM MasatosanTest2

  • Invoke a subclass method of an anonymous class

    - by arjacsoh
    I am trying right now to dig into anonymous classes and one question was just arised I 'd prefer not to refer to much details and to pose my question straightforward: How can I invoke the method sizzle() in the following anonymous class: public class Popcorn { public void pop() { System.out.println("popcorn"); } } class Food { Popcorn p = new Popcorn() { public void sizzle() { System.out.println("anonymous sizzling popcorn"); } public void pop() { System.out.println("anonymous popcorn"); } }; public void popIt() { p.pop(); // OK, Popcorn has a pop() method p.sizzle(); // Not Legal! Popcorn does not have sizzle() } } It is known and definite in polymorphism rules that a refernce of a superclass cannot invoke methods of subclass without downcasting (even if it refers to an object of the given subclass). However in the above case what is the "key" to invoke the sizzle() method?

  • Can any framework project use Struts-taglib

    - by ChronoXIII
    I have read here that one disadvantage that some may find with using Spring MVC over Struts is that Struts has tags that output HTML code, while Spring has tags that don't generate HTML. My question is can't you just use the Struts tag-lib in a Spring MVC project (or any other kind of framework project), by dropping the right jar into the WEB-INF/lib folder? Any clarification is appreciated, thanks.
