  • Overlay only draws between first 2 points in Android

    - by LordSnoutimus
    Hi, I am experiencing an unusual error using ItemizedOverlay in Android. I am creating a GPS tracking device that plots a route between waypoints stored in a database. When I provide the first two sets of longitude and latitude points through the emulator in Eclipse, it draws a red line just how I want it, but if I send another GPS point, it animates to the point, but does not draw a line from the last point. public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { points.addElement(point); } public void draw(Canvas canvas, MapView view, boolean shadow) { int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } }

  • Including a JSP Page Programatically

    - by Tom Tucker
    I need to include a JSP page in a Tag class. I believe the standard way to include a JSP page within another JSP page using API is this: request.getRequestDispatcher("included.jsp").include(request, response); However, I noticed that the included page is rendered at the top of the generated page, no matter where the code is located. On the other hand, the <jsp:include> action works as expected, rendering the included page where the tag appears in the JSP file. How do I include a JSP page in a class so that it behaves the same as the <jsp:include>? There's no way to invoke the <jsp:include> action within a Tag class, is there?

  • Load properties file in JAR?

    - by apryor48
    I'm having trouble when one of the jars that my web app depends on tries to load a properties file from within the jar. Here is the code in the jar. static { Properties props = new Properties(); try { props.load(ClassLoader.getSystemResourceAsStream("someProps.properties")); } catch (IOException e) { e.printStackTrace(); } someProperty = props.getProperty("someKey"); } The properties file is in my "src/main/resources" directory of the Maven project. When I run this code from my junit test in Eclipse, it executes just fine. When the project is built with Maven into a jar, and included as a dependency in my webb app, it fails to locate the properties file. I know that the properties file is at the base directory of the depended on jar, I don't know how to fix this. Please help!

  • How to avoid SQLiteException locking errors

    - by TheArchedOne
    I'm developing an android app. It has multiple threads reading from and writing to the android SQLite db. I am receiving the following error: SQLiteException: error code 5: database is locked I understand the SQLite locks the entire db on inserting/updating, but these errors only seems to happen when inserting/updating while I'm running a select query. The select query returns a cursor which is being left open quite a wile (a few seconds some times) while I iterate over it. If the select query is not running, I never get the locks. I'm surprised that the select could be locking the db.... is this possible, or is something else going on? What's the best way to avoid such locks? Thanks TAO

  • Google App Engine - Calling getSession().invalidate(); causes app engine to act weird.

    - by Spines
    When I call hreq.getSession().invalidate(); app engine slows down tremendously. I looked at appstats and saw that on a page where no database calls are made, it was calling memcache.get and datastore.get 23 times each. The stack trace of these calls showed that it was being called from getSession(). This only happens on the production server. Every time I make a request to a page, it makes a bunch of memcache and datastore calls. This slow down goes away though when i restart my browser. When I changed the code to simply set the isLoggedIn property of the session to false, rather than calling hreq.getSession().invalidate();, everything was fine. As a test, I didn't invalidate my session, but I changed the value of my browser's session cookie, and the app engine exhibited the same behavior. Is this a bug with the app engine?

  • The "Why" behind PMD's rules.

    - by James Kingsbery
    Is there a good resource which describes the "why" behind PMD rule sets? PMD's site has the "what" - what each rule does - but it doesn't describe why PMD has that rule and why ignoring that rule can get you in trouble in the real world. In particular, I'm interested in knowing why PMD has the AvoidInstantiatingObjectsInLoops and OnlyOneReturn rules (the first seems necessary if you need to create a new object corresponding to each object in a collection, the second seems like it is a necessity in many cases that return a value based on some criteria). Just to be clear, I know that I can disable these and how to do that, I'm just wondering why they are there in the first place. Sorry if there's something obvious I missed out there, but I did a Google search and SO search before posting this.

  • Adding S3 metadata using jets3t

    - by billintx
    I'm just starting to use the jets3t API for S3, using version 0.7.2 I can't seem to save metadata with the S3Objects I'm creating. What am I doing wrong? The object is successfully saved when I putObject, but I don't see the metadata after I get the object. S3Service s3Service = new RestS3Service(awsCredentials); S3Bucket bucket = s3Service.getBucket(BUCKET_NAME); String key = "/1783c05a/p1"; String data = "This is test data at key " + key; S3Object object = new S3Object(key,data); object.addMetadata("color", "green"); for (Iterator iterator = object.getMetadataMap().keySet() .iterator(); iterator.hasNext();) { String type = (String) iterator.next(); System.out.println(type + "==" + object.getMetadataMap().get(type)); } s3Service.putObject(bucket, object); S3Object retreivedObject = s3Service.getObject(bucket, key); for (Iterator iterator = object.getMetadataMap().keySet() .iterator(); iterator.hasNext();) { String type = (String) iterator.next(); System.out.println(type + "==" + object.getMetadataMap().get(type)); } Here's the output before putObject Content-Length==37 color==green Content-MD5==AOdkk23V6k+rLEV03171UA== Content-Type==text/plain; charset=utf-8 md5-hash==00e764936dd5ea4fab2c4574df5ef550 Here's the output after putObject/getObject Content-Length==37 ETag=="00e764936dd5ea4fab2c4574df5ef550" request-id==9ED1633672C0BAE9 Date==Wed Mar 24 09:51:44 CDT 2010 Content-MD5==AOdkk23V6k+rLEV03171UA== Content-Type==text/plain; charset=utf-8

If so, how can go about solving this?

  • Handling asynchronous responses

What would be a good approach for getting the corresponding code to a command? Below is an example of the output of Filezilla server. The response code is the three digits near the end of each line.
