• GWT: Loading different UI's based on URL

  - by jmccartie

  Trying to get a GWT project off the ground and finding it difficult to do any basic routing. Trying to fire up different UI's based on the URL. Thought I could set a string based on the getHash() and then switch off that, but seems cumbersome (and annoying since I can't do string-based switches in Java). There's got to be a best practice for this. I know Gerrit uses hashes for determining this type of information but couldn't find where they do it in the source. Or is this totally not GWT-related? Something I can handle in web.xml? Any help is much appreciated.

• how to get reply from jQuery.get request

  - by BCS

  I have a page that uses the following to submit a AJAX request: function oc() { jQuery.get( "http://somewhere.com:5001/ajax/options/", jQuery('#selectform').serialize(), function(data,statusm,xml){ // I got nothing!!! return; } ); } If I make the request manual from the address bar, things work. And when I make the request from the JS I can see via logging that the server side is working correctly, but in the call back, I can't seem to get the contents of the reply. What am I going wrong?

• iframe problem using javascript

  - by Arjun Singh

  Does anyone know how to get the HTML out of an IFRAME? I have tried several different ways: document.getElementById('iframe01').contentDocument.body.innerHTML, document.frames['iframe01'].document.body.innerHTML, document.getElementById('iframe01').contentWindow.document.body.innerHTML, etc but none of them worked. I believe the reason they're not working is that the content of my iframe doesn't have a body tag (I'm loading XML). Any other way to get all the contents of the iframe? I am open to jQuery too. This: document.getElementById('iframe01').contentWindow.document.body.innerHTML works fine in the IE, but this: document.getElementById('iframe01').contentDocument.body.innerHTML does not work for FF.

• Java String replaceAll with conditions

  - by user1483570

  I am not good in regular expressions and I need help in replacing the string. String str = "Name_XYZ_"; str = "XYZ_NAME_"; So how can I replace "Name_" or "_NAME_" from above two strings with empty string? The conditions are "Name" can be in any case and it can be at index 0 or at any index but preceded by "_". So far I tried, String replacedString = str.replaceAll("(?i)Name_", ""); // This is not correct. This is not the homework. I am working on XML file that needs such kind of processing. Please help. Thank you.

• How can I pass an object as a parameter in the google app engine RPC flow?

  - by jimmartens

  I'm building a pretty basic app, and one thing I want to do is pass an object as a parameter up through the service - async - impl instead of passing up a million separate parameters. so in async, I do something like this: import shared.Profile; ... public interface ProfileServiceAsync { public void addProfile(Profile inProf, AsyncCallback<Void> async); Now, profile is a class in com. ... .shared and I have the following in my ... .gwt.xml <source path='shared'/> That being said when I try to compile I get this error. [ERROR] Errors in 'file:/D:/projects/eclipse/workspace/.../src/com/.../client/ProfileServiceAsync.java' [ERROR] Line 11: No source code is available for type shared.Profile; did you forget to inherit a required module? Any ideas on this?

• Why isn't this simple program working?

  - by user1445478

  I'm writing a very basic program that aims for the text view to display the phrase "Hello" after a button is pressed on the screen. However, I can't get this program to work; every time I run it, it says that the application has stopped unexpectedly. This is the program I wrote: public class EtudeActivityActivity extends Activity{ TextView tvResponse; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final TextView tvResponse = (TextView) findViewById (R.id.tvResponse); } public void updateTV(View v) { tvResponse.setText("Hello"); } } Also, I inserted an android:onClick = "updateTV" into my main.xml file for the button. Thanks for any help!

• iphone dev - loading table content asynchronously

  - by Brian

  My app has a navigation controller which push and pop a series of views. One of the tableViews loads .xml file from URL and it takes 4-5 seconds. If I click the back button on the navigation bar, it will only respond after the content of the table finish loading. Is there an easy way to load the content asynchronously so that the app will still respond to my gesture on the navigation bar? p.s. I search this on the Internet and people are talking about multithreading. I don't know a lot about threads so please be more specific. Thanks in advanced =)

• Set Hibernate session's flush mode in Spring

  - by glaz666

  I am writing integration tests and in one test method I'd like to write some data to DB and then read it. @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath:applicationContext.xml"}) @TransactionConfiguration() @Transactional public class SimpleIntegrationTest { @Resource private DummyDAO dummyDAO; /** * Tries to store {@link com.example.server.entity.DummyEntity}. */ @Test public void testPersistTestEntity() { int countBefore = dummyDAO.findAll().size(); DummyEntity dummyEntity = new DummyEntity(); dummyDAO.makePersistent(dummyEntity); //HERE SHOULD COME SESSION.FLUSH() int countAfter = dummyDAO.findAll().size(); assertEquals(countBefore + 1, countAfter); } } As you can see between storing and reading data, the session should be flushed because the default FushMode is AUTO thus no data can be actually stored in DB. Question: Can I some how set FlushMode to ALWAYS in session factory or somewhere else to avoid repeating session.flush() call? All DB calls in DAO goes with HibernateTemplate instance. Thanks in advance.

• Can't find .js file in my mainBundle?!

  - by Nic Hubbard

  This is driving me crazy as I cannot figure out what in the world is going on. I load up files form you main bundle all the time, xml files, html files, etc. But, now I am trying to get the contents of a javascript file but it can never find it. I am using: NSData *jsData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"]]; if (jsData) { NSLog(@"%@", jsData); } else { NSLog(@"Can't find file"); return; } Even checking the [[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"] string returns null. My globaly.js file is in my Resources folder, the exact location where my other files are location that work totally fine using the above method. Why can't it find my js file?

• How to make a resolution independent camera preview on android?

  - by histeria

  Hi all, I'm making an android 1.6 app that uses phone's camera. In order to do this app resolution independent, I need to set a compatible aspect ratio for previewing camera on a SurfaceLayout. In 1.6 sdk there is no way to get supported sizes for the camera preview. It is possible to use a 4:3 or 3:2 aspect ratio and get no errors whith that? On the other hand, I need a way to make a xml layout that represents this Surfacelayout in this (unknown) aspect ratio in every resolution. I assume that is not possible to change the SurfaceLayout size in runtime. Can I do it with "dp" units? The other way is making this layout programmatically? There are some apps like Vignette or android camera application with some tricks to make something like that, like black bars (vignette) or fixed buttons bar, but I don't know how to do it in any kind of resolution. Any ideas? Thanks!

• Flex: Load images and swf's dynamically

  - by Lizzan

  I'm building a slide-show like application in Flex and I'm trying to load images dynamically. The images are in a folder outside the application folder. This is the folder structure: /Bildvisare-debug/ Bildvisare.html Bildvisare.swf /Images/ 01_02_01_01_B.jpg 01_02_01_01_T.JPG I'm reading the image names from an XML file and get them with a path of ../Images/01_03_01_01_B.jpg. In my mxml-file I've got an SWFLoader named picture and I try to load the images with the following code: this.picture.source = images[currentImg]; //E.g. ../Images/01_03_01_01_B.jpg this.picture.load(); The problem is that the images never show up, I only get the icon for a missing image. Can anyone help?

• What is a good solution to link different tables in Hibernate based on some field value?

  - by serg555

  I have article table and several user tables a_user, b_user, ... with exactly the same structure (but different data). I can't change anything in *_user tables except their table name prefix but can change everything else (user tables contain only user information, there is nothing about article or user_type in them). I need to link article to a user (many-to-one), but user table name is defined by user_type field. For example Article table record: ... user_id="5" user_type="a" means that it is linked to a user with id=5 from a_user table (id 5 is not unique in users scope, each user table can have its id 5). Any suggestions how to handle this situation? How can I map this relation in Hibernate (xml mapping, no annotations) so it will automatically pick up correct user for an article during select/update? How should I map user tables (one or multiple classes?)? I would need to run some queries like this: from Article a where a.userType=:type and a.user.name=:name Thanks.

• Print an EObject ?

  - by tul

  I am writing some eclipse emf code and would like to print the content of an EObject (not store it to disk). Here is what I try: public static void print(EObject obj) { Resource eResource = obj.eResource(); try { eResource.save(System.out, null); } catch (IOException e) { e.printStackTrace(); } } but that gives a NullPointerException. I have tried this instead: public static void print(EObject obj) { ResourceSet resourceSet = new ResourceSetImpl(); resourceSet.getResourceFactoryRegistry().getProtocolToFactoryMap() .put("*", new XMIResourceFactoryImpl()); Resource resource = resourceSet.createResource(URI.createURI("dummyfile.xml")); resource.getContents().add(obj); try { resource.save(System.out, null); } catch (IOException ioe) { ioe.printStackTrace(); } } This works, but is it not possible to print to screen without specifying a dummy URI??

• Set plugin’s version on the command line in maven 2

  - by larry cai

  I generate default quickstart maven example, and type mvn checkstyle:checkstyle, it always try to use the lastest SNAPSHOT version, probably it is wrong in my nexus server, but How can I set plugin's version on the command line in maven2, like 2.5 for checkstyle instead of 2.6-SNAPSHOT C:\HelloWorld>mvn checkstyle:checkstyle [INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'checkstyle'. [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Error building POM (may not be this project's POM). Project ID: org.apache.maven.plugins:maven-checkstyle-plugin Reason: Error getting POM for 'org.apache.maven.plugins:maven-checkstyle-plugin' from the repository: Failed to resolve artifact, possibly due to a repository list that is not appropriately equipped for this artifact's metadata. org.apache.maven.plugins:maven-checkstyle-plugin:pom:2.6-SNAPSHOT from the specified remote repositories: nexus (http://localhost:9081/nexus/content/groups/public) for project org.apache.maven.plugins:maven-checkstyle-plugin I guess it could be "mvn checkstyle:2.5:checkstyle", unfortunately it is not. Surely if I set build dependance in pom.xml, it will work, but I want to see how command line can works

• Java Hibernate Lazy=false

  - by Noor

  When setting Lazy=false, then hibernate will automatically loads the objects into the required sets e.g. <set name="Options" table="ATTRIBUTEOPTION" inverse="false" cascade="all" lazy="false"> <key> <column name="ATTRIBUTEID" /> </key> <one-to-many class="com.BiddingSystem.Models.AttributeOption" /> </set> but if in my xml mapping, I place lazy=true and in some place in my application i decide that i want to load all attribute options, should i do it manually, or is there a technique which lets tells hibernate that now i want to set lazy=false??

• Can not make a request to google map

  Hi I am making a restful request to google map, but I run into following error; java.io.IOException: Server returned HTTP response code: 400 for URL: http://maps.googleapis.com/maps/api/distancematrix/xml?origins=Washington, DC USA&destinations=Los+Angeles+CA+USA&mode=driving&sensor=false at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1436) at java.net.URLConnection.getContent(URLConnection.java:688) I believe its making a correct connection as I can get the correct response by copying the above URL into my browser, I am wondering why I am getting 400 error code in my console and I dont get the correct response when java is sending the request.

• Communicating between an overlayed iFrame and the underlying page (LAMP)

  - by stef

  I have a small form is to be filled in. If the user is logged in, the form is submitted as normal. If the user is not logged in, I show an overlayer with an iframe'd page that contains a login box where he enters his credentials. If the credentials are correct I can "break out" of the frame to "return" to the main page, but how can I update this main page for example to show "you are now logged in" and to change the JS / PHP login that determines whether or not the form can be submitted normally and not be intercepted again by the overlayer prompt? Afaik, these two separate pages are not aware of each other so I'm struggling to find a solution to this problem. This is in a LAMP / jQuery / CodeIgniter environment. EDIT: Could CodeIgniter's XML RPC class be useful for this?

How can a construct a small ant script that builds my src/ and test/ Java classes then runs all my JUnit tests?

• C#.NET Reload configuration settings from an external config file during run-time.

  - by user569850

  I'm writing a game server in C#.Net and would like to reload or refresh settings from a config file while the server is running. Ideally I would like to save the settings in an XML file, have the ability to edit the file while the game server is running and then send the server the command to reload the settings from the file. I know I can use a database to do this as well, but the game server is fairly small and I think it would be more practical to just save settings in a flat-file. I will have file-level access to the machine the server will run on. What should I use?

  - by Mike

  I have some xml files, which are used in my application. They are stored in the same folder with application , in subfolder DATA: "C:\MyProject\DATA\". To get the DATA folder path i use this code : static public string GetDataFolderPath() { string s = System.IO.Directory.GetCurrentDirectory().Replace(@"\bin\Debug", ""); int i = s.LastIndexOf(@"\"); s = s.Substring(0, i); i = s.LastIndexOf(@"\"); s= s.Substring(0, i); return s + @"\Data\"; } So when i want to deploy my application, i create a setup project, and add the DATA folder to Application folder. But after i install the program f.e. "C:\Project"(DATA folder- "C:\Project\DATA" i got the error: "folder C:\DATA is not found". What i need to change to make things working after deployment. Why it looks for the DATA folder on 1 level higher?
