  • Project works in eclipse but not when exported

    - by Mike
    I wrote an application that uses GraphViz to generate some graphs as .gif's according to the DOT syntax. When I run from Eclipse the images are generated fine but when I export it as a jar the images are created but there is no data in them. When I view them in Microsoft Picture Viewer its just the red X. It was working as an exported jar until I put the picture generation in its own thread. I can't seem to figure out whats going on here. Are there any problems exporting multi-threaded projects? Any one have any ideas? Thanks

  • Twitter friends timeline not returning full history

    - by twofivesevenzero
    I am using twitter4J to get a user's friends timeline, but it is not returning the full available history. I know there are pagination limits (200 per request and 3200 total as per http://bit.ly/ck8ysq) and I am well within those. I make a request like so: private static final int MAX_COUNT = 200; private List<Status> getAllStatuses(long sinceID) throws TwitterException { Twitter twitter = new Twitter(username, password); List<Status> friendsTimelineList = new ArrayList<Status>(); List<Status> tempList; int page = 0; do { page++; tempList = twitter.getFriendsTimeline( new Paging(page, MAX_COUNT, sinceID)); if(tempList == null ) break; friendsTimelineList.addAll(tempList); } while(true); return friendsTimelineList; } This results in only 423 statuses being returned across 3 pages. Any idea why this might be happening?

  • How to send HTML as GET-Request parameter?

    - by Mork0075
    I would like to send a html string with a GET request like this with Apaches HttpClient: http://sample.com/?html=<html><head>... This doesnt work at the moment, i think its an encoding problem. Do you have any ideas how to do that? method.setQueryString(new NameValuePair[] {new NameValuePair("report", "<html>....")}); client.executeMethod(method) This fails with org.apache.commons.httpclient.NoHttpResponseException: The server localhost failed to respond. If i replace "<html>" by "test.." it works fine. EDIT It seams to be a problem of URL length after encoding, the server doesnt except such long URls. Sending it as POST solves the problem.

  • Replace carriage returns and line feeds in out.println?

    - by Mike
    I am a novice coder and I am using the following code to outprint a set of Image keywords and input a "|" between them. <% Set allKeywords = new HashSet(); for (AlbumObject ao : currentObjects) { XmpManager mgr = ao.getXmpManager(); if (mgr != null) { allKeywords.addAll(mgr.getKeywordSet()); } } //get the Iterator Iterator itr = allKeywords.iterator(); while(itr.hasNext()){ String str = itr.next(); out.println(str +"|"); } %> I want the output to be like this: red|blue|green|yellow but it prints out: red| blue| green| yellow which breaks my code. I've tried this: str.replaceAll("\n", ""); str.replaceAll("\r", ""); and str.replaceAll("(?:\\n|\\r)", ""); No luck. I'd really appreciate some help!

  • Can I include both Apache Axis 1 and 2 libraries in the same project?

    - by ian_scho_es
    If it sounds like a ridiculous idea then it is. The client only wants to have to install one project on their server. Our web service will be bridging between mobile phones and various SOAP services made in .NET, Apache Axis 1 and 2, which rely on standards to transfer files such as MTOM and DIME. I am looking for an 'architecture' trick, such as develop the Axis 1 calls in a separate project and compile as a jar, to then pass it into the Axis 2 project.... Hmmm. Anything rather than having to download the source code for Axis 1 & 2 and compile them using the same xml libraries, etc. "It can't be done" is an acceptable answer. Thanks!

  • Finding occurrences of element before and after the element in Array

    - by user3718040
    I am writing a algorithm, if an array contain 3 does not contain between two 1s. like this int array={5, 2, 10, 3, 15, 1, 2, 2} the above array contain 3, before 3 there is no 1 and after 3 is one 1 it should return True. int array={3,2,18,1,0,3,-11,1,3} in this array after first element of 3 there is two 1 it should return False. I have try following code public class Third { public static void main(String[] args){ int[] array = {1,2,4,3, 1}; for(int i=0;i<array.length;i++) { if(array[i]==3) { for(int j=0;j<array[i];j++) { if(array[j]==1) { System.out.println("I foud One before "+array[j]); }else { break; } System.out.println("yes i found the array:"+array[i]); } for(int z=0;z>array[i];z++) { if(array[z]==1) { System.out.println("I found after 3 is :"+array[z]); } break; } } } } } I am not getting exact result from my above code which i want.

  • How to change the picture of CustomButtonField on click event?

    - by Ujjal boruah Vinod
    I have posted this question previously but the answer is not appropiate. The solution provided just change the picture when the custombutton has focus and unfocus. Suppose in my application I need to change the picture if the user clicks on the customButton, n i m doing this by calling the same screen (ie UiApplication.getUiApplication().pushScreen(new Screen2(b));) . Screen2 is the screen which holds the customButton. On the click evevt i m pushing the same screen by passing aint variable pic_status that determines which picture to be drawn in the CustomButton in the new screen. Is there any way to update the picture in the CustomButtonField on click event without pushing the same Screen again and again. //code in Screen2 public void fieldChanged(Field field, int context) { if(field == bf1) { if(pic_status == 0) { pic_status=1; } UiApplication.getUiApplication().pushScreen(new Screen2(pic_status)); } //code in CustomButtonField CustomButtonField(String label,int pic_status,long style) { super(style); this.label = label; this.labelHeight = getFont().getHeight(); this.labelWidth = getFont().getAdvance(label); this.notice = s; if(pic_status ==0) { currentPicture1 = onPicture; currentPicture2 = onPicture; } if(pic_status ==1) { currentPicture1 = clickPicture; currentPicture2 = onPicture; } if( pic_status==2 ) { currentPicture1 = onPicture; currentPicture2 = clickPicture; } } I need a way to update the customButtonField text and picture on the buttonClick event not on focus/unfocus event without pushing the same Screen again and again. If my above description of problem is not satisfactory, plz add a comment n i can give more details explanation of my problem?

  • Activiti Engine: Task Event - User is null

    - by sockeqwe
    I have a problem, which should be simple to solve, but i can't find the method to call to solve this problem: My problem is, that every Task Event (org.activiti.engine.task.Event) returnes null by calling Event.getUserId(); If I take a look into the database I see that the database table ACT_HI_COMMENT has null as value for the column USER_ID_ for every row. I generate these TaskEvents programmatically by calling (for example) processEngine.getTaskService().addComment(task.getId(), null, commentMessage); processEngine.getTaskService().addUserIdentityLink(task.getId(), user.getId(), IDENTITY_LINK_OBSERVER); I guess there is a simple method that I must call to solve this problem, something like processEngine.setCurrentUser(authenticatedUser.getId()); Any suggestions?

  • Android/ORMLite Insert Row with ID

    - by Joe M
    I'm currently using ORMLite to work with a SQLite database on Android. As part of this I am downloading a bunch of data from a backend server and I'd like to have this data added to the SQLite database in the exact same format it is on the backend server (ie the IDs are the same, etc). So, my question to you is if I populate my database entry object (we'll call it Equipment), including Equipment's generatedId/primary key field via setId(), and I then run a DAO.create() with that Equipment entry will that ID be saved correctly? I tried it this way and it seems to me that this was not the case. If that is the case I will try again and look for other problems, but with the first few passes over the code I was not able to find one. So essentially, if I call DAO.create() on a database object with an ID set will that ID be sent to the database and if it is not, how can I insert a row with a primary key value already filled out? Thanks!

  • How to trigger the specific controller action using a button?

    - by Eugene
    I'm creating a simple training project. I've implemented a controller method, which deletes an item from the list. The method is looking like this: @Controller @RequestMapping(value = "/topic") public class TopicController { @Autowired private TopicService service; ... @RequestMapping(value = "/deleteComment/{commentId}", method = RequestMethod.POST) public String deleteComment(@PathVariable int commentId, BindingResult result, Model model){ Comment deletedComment = commentService.findCommentByID(commentId); if (deletedComment != null) { commentService.deleteComment(deletedComment); } return "refresh:"; } } This method is called from the button-tag, which is looking in the following way: _form> _button formaction = "../deleteComment/1" formmethod = "post">delete_/button> _/form> Sorry, but in the form tag I've changed all the '<' characters with the '_', because the tag was invisible. In my project the form-tag is looking like a cliuckable button. But there is a serious problem: controller's method is never triggered. How can I trigger it, using a button-tag? P.S. the call is performed from the page with URI http://localhost:8080/simpleblog/topic/details/2 and controller's URI is the http://localhost:8080/simpleblog/topic/deleteComment/2

  • How do I manipulate a tree of immutable objects?

    - by Frederik
    I'm building an entire application out of immutable objects so that multi-threading and undo become easier to implement. I'm using the Google Collections Library which provides immutable versions of Map, List, and Set. My application model looks like a tree: Scene is a top-level object that contains a reference to a root Node. Each Node can contain child Nodes and Ports. An object graph might look like this: Scene | +-- Node | +-- Node | +- Port +-- Node | +- Port +- Port If all of these objects are immutable, controlled by a top-level SceneController object: What is the best way to construct this hierarchy? How would I replace an object that is arbitrarily deep in the object tree? Is there a way to support back-links, e.g. a Node having a "parent" attribute?

  • How to debug ConcurrentModificationException?

    - by Dani
    I encountered ConcurrentModificationException and by looking at it I can't see the reason why it's happening; the area throwing the exception and all the places modifying the collection are surrounded by synchronized (this.locks.get(id)) { ... } // locks is a HashMap<String, Object>; I tried to catch the the pesky thread but all I could nail (by setting a breakpoint in the exception) is that the throwing thread owns the monitor while the other thread (there are two threads in the program) sleeps. How should I proceed? What do you usually do when you encounter similar threading issues?

  • Click Listener not invoked within ListFragment

    - by membersound
    I'm extending a SherlockListFragment, but it should not matter as my question seems to be more general related to Fragments. Now, I implement a simple click listener for my list, but it does not get called. public class MyListFragment extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.list, container, false); v.setOnClickListener(new OnClickListener() { public void onClick(View view) { Log.i("debug", "single click"); } }); return v; } } Is anything wrong with this? //Solution: listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.i("debug", "single click"); } });
