  • Weird parsing date string error in Android 2.0 emulator

    - by kknight
    I have a simple test code for testing SimpleDateFormat. This code works well on Eclipse and Android 1.5 emulator, but it failed at Android 2.0 emulator. Does anyone know why? Thanks. public class TemplateActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText(R.string.hello); setContentView(tv); SimpleDateFormat format = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz"); String dateStr = "Mon, 17 May 2010 01:45:41 GMT"; try { Date parsed = format.parse(dateStr); Log.v("Test", parsed.toString()); } catch (ParseException pe) { Log.v("Test", "ERROR: Cannot parse \"" + dateStr + "\""); } } } Log message: V/Test( 400): ERROR: Cannot parse "Mon, 17 May 2010 01:45:41 GMT"

  • Customizing TabWidget in SDK 1.5, API 3

    - by Dylan McClung
    I'm aware that API 3 doesn't allow a view to be set for a tab, but I still need to modify the TextView displayed as the indicator. I'd also like to change the Drawable for the tab, but I don't see a way to do it without a custom tab view as allowed in 1.6, API 4. Working with this generic example below, is there way to retrieve the TextView and modify its properties or change the drawable? TabHost tabHost = getTabHost(); TabHost.TabSpec spec; spec = tabHost.newTabSpec("nearby") .setIndicator("Nearby Activity") .setContent(R.id.nearby_list); tabHost.addTab(spec); spec = tabHost.newTabSpec("friends") .setIndicator("Friends & Favorites") .setContent(R.id.friends_list); tabHost.addTab(spec); tabHost.setCurrentTabByTag("nearby"); Thanks for any help.

  • Benefits of arrays

    - by Vitalii Fedorenko
    As I see it, the advantages of List over array are pretty obvious: Generics provide more precise typing: List<Integer>, List<? extends Number>, List<? super Integer>. List interface has a bunch useful methods: addAll, remove etc. While for arrays all standard operations except get/set must be performed in a procedure manner by passing it to a static method. Collections offer different implementations like ArrayList, LinkedList, unmodifieable and synchronized lists, which can be hidden under common List interface. OOB length control. As disadvantages I can only mention absence of syntactic sugar and runtime type check. At the same time supporting of both structures requires frequent using of asList and toArray methods, which makes code less readable. So I am curious if there are any important benefits of using arrays that I miss.

  • How can I add a .jar to my build path in Eclipse?

    - by Roman
    I try to do it the following way: Right click on the name of the project. Click on Build Path in the drop dawn menu. Click on "Configure Build Path" And then I do not know what to do. Should I select "Source", "Projects", "Libraries", "Order and Export"? In "Libraries" I have "Add JARs..." and "Add External JARs...". What should I select? (I have already a .jar file in the lib folder of my project.) ADDED: If I click on "Add JARs" in the "Libraries" tab, I see the "lib" sub-folder but if I go there I do not see my .jar file there (and I know that it is there).

  • Two collections manyToOne to same primary key

    - by Ethiel
    Hi, guys, I'm coding a web page in Hibernate-JPA and Oracle. I need the following: I have two classes: Place and Home. I need two collections of type Place in every Home: I do the following: Home: @ManyToOne @JoinColumn(name="ID_PLACES") private List<Places>places1; @ManyToOne @JoinColumn(name="ID_PLACES") private List<Places>Places2; However, hibernate got an exception (repeated column) and forces to me to mapping with insert and update to false. How Can I get Two ManyToOne relationship to same primary key with insert a true?.

  • pattern to transfer search model to dao

    - by zeroed
    We have a dao as a project (jar file). Clients use its interfaces and factories to operate with database. Using standard CRUD operations, dao allows you to search an entity by some search criteria. What is the best way to represent this criteria? Is transfer object appropriate pattern in this situation? How should client create SearchModel instance? Please, share. Regards.

  • Why new String(bytes, enc).getBytes(enc) does not return the original byte array?

    - by Bozho
    I made the following "simulation": byte[] b = new byte[256]; for (int i = 0; i < 256; i ++) { b[i] = (byte) (i - 128); } byte[] transformed = new String(b, "cp1251").getBytes("cp1251"); for (int i = 0; i < b.length; i ++) { if (b[i] != transformed[i]) { System.out.println("Wrong : " + i); } } For cp1251 this outputs only one wrong byte - at position 23. For KOI8-R - all fine. For cp1252 - 4 or 5 differences. What is the reason for this and how can this be overcome? I know it is wrong to represent byte arrays as strings in whatever encoding, but it is a requirement of the protocol of a payment provider, so I don't have a choice. Update: representing it in ISO-8859-1 works, and I'll use it for the byte[] part, and cp1251 for the textual part, so the question remains only out of curiousity

  • any way to use ajax with jstl customtags without duplicating tags in javascript?

    - by CodeMonkeyB
    I am working on a page where part of the content is loaded normally and the pages are rendered using jsps. The product images and links generated on that page are by custom jstl tags. When the user scrolls more products are requested from the server in a JSON response and then using UnderscoreJS templates they are rendered and added to the bottom of the page. Is there any way I can use the JSTL tags in Javascript without recreating them using a javascript function (it won't be possible to re-create all of them in javascript). What is the best way to handle this scenario? I guess I could return a rendered html response for the ajax call, but that would mean I have some ajax requests which use json and some that use rendered html...

  • How to integrate maven generated vaadin project into eclipse vaadin plugin?

    - by float_dublin
    Eclipse Vaadin plugin has cool autobuild feature. Just clicking "restart application" in debug console will bring up to date application version to live. Unfortunately importing maven generated vaadin project(using m2e) and copy-pasting .project buildCommands and natures from vaadin eclipse plugin generated project does not works. I'm unnable to "Run on server...", tomcat does not deploy app for unknown reason. I can see app in wtpapps folder but it still does not deploys.

  • Is it possible to use instanceof when passing objects between Threads?

    - by Risser
    I've run into an issue where instanceof works, and then it doesn't. Going into details is difficult, but I think this might be the problem: Reading this: http://www.theserverside.com/news/thread.tss?thread_id=40229 (search for Thread.currentThread), it seems to imply that, even if the two objects are the same class, if you pass them between threads with different class loaders, instanceof (and isAssignableFrom) might still fail. This certainly would explain the behavior I'm having, but I was wondering if anyone could verify it? (I wish the article linked at the beginning of the discussion was still available, but it doesn't seem like it is.) Thanks, Peter

  • Business Tier | client state in desktop application- way around Stateful Session Beans?

    - by arthur
    I read positive inputs on the following posts concerning client state management: Stateful EJBs in web application?, here, and here. I want to know how implement such client state management for desktop applications (Swing, AWT, SWT, and other). let's assume there are n desktop clients supposed to use some (remote) services provided on an Application Server. How to maintain a separate and permanent data state for each client , distinct from the other without have to use using stateful session Beans (SFSB) ? is that even possible on this application type ? With Webapp(Servlets / JsSF and JSP) some can avoid using SFSB by HttpSession object and/or coupling it with stateless session beans (SLSB). HttpSession object would keep information for each (Web)client separate and the SLSB would play the business logic music. But HttpSession objects aren't present on desktop application and I go stuck with only SFSB and SLSB. Knowing the problems(Concurrency, Error Handling, usw ) of SFSB, I would have not wanted to use it. What would be the other options? is there only SFSB available? Thanks in advances

  • Injecting the application TransactionManager into a JPA EntityListener

    - by nodje
    I want to use the JPA EntityListener to support spring security ACLs. On @PostPersist events, I create a permission corresponding to the persisted entity. I need this operation to participate to the current Transaction. For this to happen I need to have a reference to the application TransactionManager in the EntityListener. The problem is, Spring can't manage the EntityListener as it is created automatically when EntityManagerFactory is instantiated. And in a classic Spring app, the EntityManagerFactory is itself created during the TransactioManager instantiation. <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> So I have no way to inject the TransactionManager with the constructor, as it is not yet instantiated. Making the EntityManager a @Component create another instance of the EntityManager. Implementing InitiliazingBean and using afterPropertySet() doesn't work as it's not a Spring managed bean. Any idea would be helpful as I'm stuck and out of ideas.

    I have deployed my project to tomcat root, and it works fine without any problem. To acheive this I created a ROOT file TOMCAT_HOME/conf/Catalina/localhost/ROOT.xml with content below: <Context docBase="/home/user/project.war" path="" reloadable="true" /> So right now I can see my project under localhost:8080/ without any problem.. but I don't know where my project has been extracted, there is even no ROOT directory under TOMCAT_HOME/webapps, any idea?

  • How can I retrieve cookies for webserver A when my project is deployed on webserver B?

    - by medopal
    The project is multiple modules, each of them is deployed to a separate webserver. All of them on the same mainframe. (same IP address) I have a main menu where I login and then list all the available modules on all servers. From here I can click and go to any of them modules. I send cookies in the response (when logging in, say Server A), then on Server B (one of the modules) when I want to go back to the main menu, I check the cookies to see if the user is logged in. The problem is, Server B isn't seeing cookies generated by Server A. So each time I return to main menu, the user will be logged out. Is there anyway to store cookies to be used by multiple virtual webservers (on same IP) or any other idea?

  • Share Link - Perform action in background

    - by Justin
    I have an application that will accept URLs from the built in web browser via the "Share page" menu item. I'm using the send intent and it works just fine. However, I'd like to accept a URL and process it in the background without bringing my application to the front. I don't want the user to have to actually leave the web browser. It will notify the user it has finished processing the URL with a Toast message. I'm just not sure what type of activity should be used for this. A good example of this behavior is the "Read Later" instapaper application in the android market. Any help would be greatly appreciated.
