• I create a JPanel and GridBagLayout within an object but when I get it in the main object, attributes are missing

When calling the functions in another file, it looks like I just get the JPanel (but without any labels or the layout or other GridBagLayout features). Help?

• Setting JMX attribute on VM as command line paramater

  - by 117440226733149663383

  I've done some searching, but can't seem to find a way to do this. We'd like to proactively monitor our permgen space via JMX. It seems the best way to do this is through the UsageThreshold attribute on the "PS Perm Gen" MemoryPool. By default, this is set to 0. Is there a way to specify this, or any JMX attribute, as a -D parameter to VM so this can be set automatically at startup? Or is there another mechanism to load JMX attributes automatically? Thanks.

• How to remove the file suffix/extension (.jsp and .action) using the Stripes Framework?

  - by Dolph Mathews

  I'm looking to use pretty / clean URL's in my web app. I would like the following URL: http://mydomain.com/myapp/calculator .. to resolve to: com.mydomain.myapp.action.CalculatorActionBean I tried overwriting the NameBasedActionResolver with: public class CustomActionResolver extends NameBasedActionResolver { public static final String DEFAULT_BINDING_SUFFIX = "."; @Override protected String getBindingSuffix() { return DEFAULT_BINDING_SUFFIX; } @Override protected List<String> getActionBeanSuffixes() { List<String> suffixes = new ArrayList<String>(super.getActionBeanSuffixes()); suffixes.add(DEFAULT_BINDING_SUFFIX); return suffixes; } } And adding this to web.xml: <servlet-mapping> <servlet-name>StripesDispatcher</servlet-name> <url-pattern>*.</url-pattern> </servlet-mapping> Which gets me to: http://mydomain.com/myapp/Calculator. But: A stray "." is still neither pretty nor clean. The class name is still capitalized in the URL..? That still leaves me with *.jsp..? Is it even possible to get rid of both .action and .jsp?

• Spring @Autowired and WebApplicationContext in Tomcat

  - by EugeneP

  @Autowired works only once. What to do to make it wire the bean every time the Servlet is recreated? My web-app (Tomcat6 container) consists of 2 Servlets. Every servlet has private fields. Their setters are marked with @Autowired In the init method I use WebApplicationContextUtils ... autowireBean(this); It autowires the properties marked with @Autowired once - during the initialization of the Servlet. Any other session will see these fields values, they will not be rewired after the previous session is destroyed. What to do to make them rewire them each time a Servlet constructor is called? a) Put the autowiring into the constructor? Or better 2) get a web app context and extract a bean from there?

• Issue with multipart/form-data

  - by kbrin80

  I am not able to get values from both files and text input in a servlet when my form includes multipart/form-data. I am using the apache.commons.fileuploads for help with the uploads. Any suggestions. Also in the code below there are some things that I feel should be more efficient. Is there a better way to store these multiple files in a db. public void performTask(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) { boolean promo = false; Database db = new Database(); Homepage hp = db.getHomePageContents(); String part = ParamUtils.getStringParameter(request, "part", ""); if(part.equals("verbage")) { String txtcontent = (String)request.getParameter("txtcontent"); String promoheader = (String)request.getParameter("promoheader"); String promosubheader = (String)request.getParameter("promosubheader"); hp.setBodyText(txtcontent); hp.setPromoHeader(promoheader); hp.setPromoSubHeader(promosubheader); System.err.println(txtcontent); } else { boolean isMultipart = ServletFileUpload.isMultipartContent(request); if (!isMultipart) { } else { FileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); List items = null; try { items = upload.parseRequest(request); //System.err.print(items); } catch (FileUploadException e) { e.printStackTrace(); } Iterator itr = items.iterator(); while (itr.hasNext()) { FileItem item = (FileItem) itr.next(); if(item.getFieldName().equals("mainimg1")) { if(item.getName() !="") hp.setMainImg1(item.getName()); } if(item.getFieldName().equals("mainimg2")) { if(item.getName() !="") hp.setMainImg2(item.getName()); } if(item.getFieldName().equals("mainimg3")) { if(item.getName() !="") hp.setMainImg3(item.getName()); } if(item.getFieldName().equals("promoimg1")) { promo = true; if(item.getName() !="") { hp.setPromoImg1(item.getName()); try { File savedFile = new File("/Library/resin-4.0.1/webapps/ROOT/images/promoImg1.jpg"); item.write(savedFile); //System.err.print(items); } catch (Exception e) { System.err.println(e.getMessage()); } } } if(item.getFieldName().equals("promoimg2")) { if(item.getName() !="") { hp.setPromoImg2(item.getName()); try { File savedFile = new File("/Library/resin-4.0.1/webapps/ROOT/images/promoImg2.jpg"); item.write(savedFile); //System.err.print(items); } catch (Exception e) { System.err.println(e.getMessage()); } } } if(item.getFieldName().equals("promoimg3")) { if(item.getName() !="") { hp.setPromoImg3(item.getName()); try { File savedFile = new File("/Library/resin-4.0.1/webapps/ROOT/images/promoImg3.jpg"); item.write(savedFile); //System.err.print(items); } catch (Exception e) { System.err.println(e.getMessage()); } } } System.err.println("FNAME =" + item.getFieldName() + " : " + item.getName()); if (item.isFormField()) { } else { try { if(!promo) { String itemName = item.getName(); File savedFile = new File("/Library/resin-4.0.1/webapps/ROOT/images/"+itemName); item.write(savedFile); } //System.err.print(items); } catch (Exception e) { System.err.println(e.getMessage()); } } } } } db.updateHomePageContent(hp);

• Tomcat - Redirect to Error Page when ServletContextListener fails

  - by Vic

  When Tomcat starts it calls my ServletContextListener to obtain a database connection, which I will later use in other servlets with getServletContext(). It is called in my web.xml as: listener listener-class org.ppdc.database.DBCPoolingListener /listener-class /listener (I removed the < because they wouldn't display properly in this message. If I cannot connect to the database when Tomcat starts up I get a 404 error, because Tomcat cannot start the application. How can I redirect the user to a custom error page at this point? I tried the following in my web.xml (I have the < brackets in the original): (error-page) (error-code404/error-code) (location/file_not_found.html/location) (/error-page) Any ideas on how to redirect a user to one of my error pages when Tomcat tries to start the application? Thanks Vic

• Drawing to the canvas

  - by Mattl

  I'm writing an android application that draws directly to the canvas on the onDraw event of a View. I'm drawing something that involves drawing each pixel individually, for this I use something like: for (int x = 0; x < xMax; x++) { for (int y = 0; y < yMax; y++){ MyColour = CalculateMyPoint(x, y); canvas.drawPoint(x, y, MyColour); } } The problem here is that this takes a long time to paint as the CalculateMyPoint routine is quite an expensive method. Is there a more efficient way of painting to the canvas, for example should I draw to a bitmap and then paint the whole bitmap to the canvas on the onDraw event? Or maybe evaluate my colours and fill in an array that the onDraw method can use to paint the canvas? Users of my application will be able to change parameters that affect the drawing on the canvas. This is incredibly slow at the moment.

• method names with fluent interface

  - by deamon

  I have a Permissions class with methods in fluent style like this: somePermissions.setRead(true).setWrite(false).setExecute(true) The question is, whether I should name these methods set{Property} or only {property}. The latter would look like this: somePermissions.read(true).write(false).execute(true) If I look at these methods separately I would expect that read reads something, but on the other hand it is closer to the intention to have something like named paramaters like in Scala: Permission(read=true, write=false, execute=true)

• Junit import using * wildcard

  - by Xenorose

  I've noticed that when importing JUnit, the * wildcard doesn't always work. e.g. for the annotation @Test you must import org.junit.Test since org.junit.* doesn't recognize the annotation. Is there a reason for this, is it something that needs setting? or just a quirk in the way somethings like JUnit are. FYI, I am using: Junit 4.6, Intelli-J 8.1.3.

• how can i unmarshall in jaxb and enjoy the schema validation without using an explicit schema file

  - by ekeren

  I am using jaxb for my application configurations I feel like I am doing something really crooked and I am looking for a way to not need an actual file or this transaction. As you can see in code I: 1.create a schema into a file from my JaxbContext (from my class annotation actually) 2.set this schema file in order to allow true validation when I unmarshal JAXBContext context = JAXBContext.newInstance(clazz); Schema mySchema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(schemaFile); jaxbContext.generateSchema(new MySchemaOutputResolver()); // ultimately creates schemaFile Unmarshaller u = m_context.createUnmarshaller(); u.setSchema(mySchema); u.unmarshal(...); do any of you know how I can validate jaxb without needing to create a schema file that sits in my computer? Do I need to create a schema for validation, it looks redundant when I get it by JaxbContect.generateSchema ? How do you do this?

• Interface Design Problem: Storing Result of Transactions

  - by jboyd

  Requirements: multiple sources of input (social media content) into a system multiple destinations of output (social media api's) sources and destinations WILL be added some pseudo: IContentProvider contentProvider = context.getBean("contentProvider"); List<Content> toPost = contentProvider.getContent(); for (Content c : toPost) { SocialMediaPresence smPresence = socialMediaService.getSMPresenceBySomeId(c.getDestId()); smPresence.hasTwitter(); smPresence.hasFacebook(); //just to show what this is smPresence.postContent(c); //post content could fail for some SM platforms, but shoulnd't be lost forever } So now I run out of steam, I need to know what content has been successfully posted, and if it hasn't gone too all platforms, or if another platform were added in the future that content needs to go out for it as well (therefore my content provider will need to not only know if content has gone out, but for what platforms). I'm not looking for code, although sample/pseudo is fine... I'm looking for an approach to this problem that I can implement

• Cursor while loop returning every value but the last

  - by LordSnoutimus

  Hello, I am using a while loop to iterate through a cursor and then outputing the longitude and latitude values of every point within the database. For some reason it is not returning the last (or first depending on if I use Cursor.MoveToLast) set of longitude and latitude values in the cursor. Here is my code: public void loadTrack() { SQLiteDatabase db1 = waypoints.getWritableDatabase(); Cursor trackCursor = db1.query(TABLE_NAME, FROM, "trackidfk=1", null, null, null,ORDER_BY); trackCursor.moveToFirst(); while (trackCursor.moveToNext()) { Double lat = trackCursor.getDouble(2); Double lon = trackCursor.getDouble(1); //overlay.addGeoPoint( new GeoPoint( (int)(lat*1E6), (int)(lon*1E6))); System.out.println(lon); System.out.println(lat); } } From this I am getting: 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 2.0 04-02 15:39:07.416: INFO/System.out(10551): 2.0 04-02 15:39:07.493: INFO/System.out(10551): 1.0 04-02 15:39:07.493: INFO/System.out(10551): 1.0 7 Sets of values, where I should be getting 8 sets.

• Should I use a collection here?

  - by Eva

  So I have code set up like this: public interface IInterface { public void setField(Object field); } public abstract class AbstractClass extends JPanel implements IInterface { private Object field_; public void setField(Object field) { field_ = field; } } public class ClassA extends AbstractClass { public ClassA() { // unique ClassA constructor stuff } public Dimension getPreferredSize() { return new Dimension(1, 1); } } public class ClassB extends AbstractClass { public ClassB() { // unique ClassB constructor stuff } public Dimension getPreferredSize() { return new Dimension(42, 42); } } public class ConsumerA { public ConsumerA(Collection<AbstractClass> collection) { for (AbstractClass abstractClass : collection) { abstractClass.setField(this); abstractClass.repaint(); } } } All hunky-dory so far, until public class ConsumerB { // Option 1 public ConsumerB(ClassA a, ClassB b) { methodThatOnlyTakesA(a); methodThatOnlyTakesB(b); } // Option 2 public ConsumerB(Collection<AbstractClass> collection) { for (IInterface i : collection) { if (i instanceof ClassA) { methodThatOnlyTakesA((ClassA) i); else if (i instanceof ClassB) { methodThatOnlyTakesB((ClassB) i); } } } } public class UsingOption1 { public static void main(String[] args) { ClassA a = new ClassA(); ClassB b = new ClassB(); Collection<AbstractClass> collection = Arrays.asList(a, b); ConsumerA consumerA = new ConsumerA(collection); ConsumerB consumerB = new ConsumerB(a, b); } } public class UsingOption2 { public static void main(String[] args) { Collection<AbstractClass> collection = Arrays.asList(new ClassA(), new ClassB()); ConsumerA = new ConsumerA(collection); ConsumerB = new ConsumerB(collection); } } With a lot more classes extending AbstractClass, both options get unwieldly. Option1 would make the constructor of ConsumerB really long. Also UsingOption1 would get long too. Option2 would have way more if statements than I feel comfortable with. Is there a viable Option3? If it helps, ClassA and ClassB have all the same methods, they're just implemented differently. Thanks for slogging through my code!

• handling filename* parameters with spaces via RFC 5987 results in '+' in filenames

  - by Peter Friend

  I have some legacy code I am dealing with (so no I can't just use a URL with an encoded filename component) that allows a user to download a file from our website. Since our filenames are often in many different languages they are all stored as UTF-8. I wrote some code to handle the RFC5987 conversion to a proper filename* parameter. This works great until I have a filename with non-ascii characters and spaces. Per RFC, the space character is not part of attr_char so it gets encoded as %20. I have new versions of Chrome as well as Firefox and they are all converting to %20 to + on download. I have tried not encoding the space and putting the encoded filename in quotes and get the same result. I have sniffed the response coming from the server to verify that the servlet container wasn't mucking with my headers and they look correct to me. The RFC even has examples that contain %20. Am I missing something, or do all of these browsers have a bug related to this? Many thanks in advance. The code I use to encode the filename is below. Peter public static boolean bcsrch(final char[] chars, final char c) { final int len = chars.length; int base = 0; int last = len - 1; /* Last element in table */ int p; while (last >= base) { p = base + ((last - base) >> 1); if (c == chars[p]) return true; /* Key found */ else if (c < chars[p]) last = p - 1; else base = p + 1; } return false; /* Key not found */ } public static String rfc5987_encode(final String s) { final int len = s.length(); final StringBuilder sb = new StringBuilder(len << 1); final char[] digits = {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'}; final char[] attr_char = {'!','#','$','&','\'','+','-','.','0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','^','_','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','|', '~'}; for (int i = 0; i < len; ++i) { final char c = s.charAt(i); if (bcsrch(attr_char, c)) sb.append(c); else { final char[] encoded = {'%', 0, 0}; encoded[1] = digits[0x0f & (c >>> 4)]; encoded[2] = digits[c & 0x0f]; sb.append(encoded); } } return sb.toString(); } Update Here is a screen shot of the download dialog I get for a file with Chinese characters with spaces as mentioned in my comment.
