  • Inconsistent GWT behavior in IE 8

    - by Don Branson
    All, I have a web site that's built with GWT at https://penwag.com/penwag/. If you just hit the site and see the main page, there's supposed to be a login/registration area that displays, along with a teaser for the site. I've tried the site with most of the main browsers - FF 3 & 3.5, IE 6 & 8, Safari, and Chrome, and all appears well to me. However, I have a non-geek user that has visited the site from both work and home. The work computer can see the intro page fine, but the home computer shows only the static content, and non of the javascript-based portion, that is the login/registration and teaser. Both computers are using IE 8. He checked the computer where the site fails, and scripting is enabled. Can anyone else see the problem? (You don't have to register to see the problem, just hit the main page.) Anything else I should check or have him try? Thanks! Edit: The site is implemented using GWT 1.7.0. I'll have to find out about the OS versions. Edit: The one that works is running Windows XT, the failing one is running Windows Vista. (There's a shocker!) I myself have viewed it successfully with both OSs. Edit: I've since completely re-structured the site, and documented the changes here: http://penwag.blogspot.com/2010/04/april-penwag-update.html So, the site is no longer the same as when I asked this question.

  • How to align Button to the right, without being overlapped by TextView?

    - by Kilnr
    Hello, I'm trying to get something like this: http://img202.imageshack.us/img202/552/layoutoy.png. I'm using this as a list item (technically as the group view of an ExpandableListView). Here's the XML file: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight"> <TextView android:id="@+id/list_item_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:ellipsize="end" /> <Button android:id="@+id/list_item_button" android:text="Click me!" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_toRightOf="@id/list_item_text" /> </RelativeLayout> But this doesn't work. The Button doesn't wrap its contents, instead it uses all available horizontal space. The TextView does wrap its contents, but what I want it to do is to cut off when it overlaps the Button. In other words, I want all the buttons to be of the same width, regardless of the amount of text in the textviews. Is this at all possible?

  • req.getParameter returns values wrong character encoding

    - by coder247
    I'm trying to get values from a JSP using getParameter which includes ü,é,à etc. But get wrong values in servlet. I've checked the content type with firebug and found that Content-Type text/html;charset=UTF-8 checked the POST section with firebug and found the correct value there, when I try to access it in servlet it is wrong. Gives ö instead of ö req.getCharacterEncoding(); returns null. Tried with setting req.setCharacterEncoding("UTF-8"); at the beginning of servlet but didn't help.

  • Validating parameters according to a fixed reference

    - by James P.
    The following method is for setting the transfer type of an FTP connection. Basically, I'd like to validate the character input (see comments). Is this going overboard? Is there a more elegant approach? How do you approach parameter validation in general? Any comments are welcome. public void setTransferType(Character typeCharacter, Character optionalSecondCharacter) throws NumberFormatException, IOException { // http://www.nsftools.com/tips/RawFTP.htm#TYPE // Syntax: TYPE type-character [second-type-character] // // Sets the type of file to be transferred. type-character can be any // of: // // * A - ASCII text // * E - EBCDIC text // * I - image (binary data) // * L - local format // // For A and E, the second-type-character specifies how the text should // be interpreted. It can be: // // * N - Non-print (not destined for printing). This is the default if // second-type-character is omitted. // * T - Telnet format control (<CR>, <FF>, etc.) // * C - ASA Carriage Control // // For L, the second-type-character specifies the number of bits per // byte on the local system, and may not be omitted. final Set<Character> acceptedTypeCharacters = new HashSet<Character>(Arrays.asList( new Character[] {'A','E','I','L'} )); final Set<Character> acceptedOptionalSecondCharacters = new HashSet<Character>(Arrays.asList( new Character[] {'N','T','C'} )); if( acceptedTypeCharacters.contains(typeCharacter) ) { if( new Character('A').equals( typeCharacter ) || new Character('E').equals( typeCharacter ) ){ if( acceptedOptionalSecondCharacters.contains(optionalSecondCharacter) ) { executeCommand("TYPE " + typeCharacter + " " + optionalSecondCharacter ); } } else { executeCommand("TYPE " + typeCharacter ); } } }

    - by Amir Rachum
    Hi all, I'm using the PMD plugin for eclipse and it gives me an error when using System.out.println() with the explanation: System.(out|err).print is used, consider using a logger. My question is - What is a Logger? How is it used to print to the screen? Why is it better? Thanks.

  • Problem processing large data using Applet-Servlet communication

    - by Marquinio
    Hi everyone. I have an Applet that makes a request to a Servlet. On the servlet it's using the PrintWriter to write the response back to Applet: out.println("Field1|Field2|Field3|Field4|Field5......|Field10"); There are about 15000 records, so the out.println() gets executed about 15000 times. Problem is that when the Applet gets the response from Servlet it takes about 15 minutes to process the records. I placed System.out.println's and processing is paused at around 5000, then after 15 minutes it continues processing and then its done. Has anyone faced a similar problem? The servlet takes about 2 seconds to execute. So seems that the browser/Applet is too slow to process the records. Any ideas appreciated. Thanks.

  • "Zoom" text to be as big as possible within constraints/box

    - by stolsvik
    First problem: You have 400 pixels width to go on, and need to fit some text within that constraint as large as possible (thus, the text shall use that amount of space). Throw in a new constraint: If the text is just "A", then it shall not zoom this above 100 pixels (or some specific font size). Then, a final situation: Linebreaks. Fit some text in the largest possible way within e.g. 400 x 150 pixels. An obvious way is to simply start with point 1, and then increase until you can't fit it anymore. This would work for all three problems, but would be very crude. The fitting of a single line within bounds could be done by writing it with some fixed point size, check the resulting pixel bounds of the text, and then simply scale it with a transform (the text scales properly too then, check out TransformUI). Any ideas of other ways to attack this would be greatly appreciated!

  • Long To XMLGregorianCalendar and back to Long

    - by JD.
    I am trying to convert from millisecond time stamp to XMLGregorianCalendar and back, but I seem to be getting wrong results. Am I doing something wrong? It seems I am gaining days. // Time stamp 01-Jan-0001 00:00:00.000 Long ts = -62135740800000L; System.out.println(ts); System.out.println(new Date(ts)); // Sat Jan 01 00:00:00 PST 1 .. Cool! // to Gregorian Calendar GregorianCalendar gc = new GregorianCalendar(); gc.setTimeInMillis(ts); // to XML Gregorian Calendar XMLGregorianCalendar xc = DatatypeFactory.newInstance().newXMLGregorianCalendar(gc); // back to GC GregorianCalendar gc2 = xc.toGregorianCalendar(); // to Timestamp Long newTs = gc2.getTimeInMillis(); System.out.println(newTs); // -62135568000000 .. uh? System.out.println(new Date(newTs)); // Mon Jan 03 00:00:00 PST 1 .. where did the extra days come from?

  • Why my HttpPost can't receive all response data?

    - by Johnny
    I'm on Android 1.5, and my code is like this: HttpPost httpPost = new HttpPost(url); HttpEntity entity = new UrlEncodedFormEntity(params, HTTP.UTF_8); httpPost.setEntity(entity); HttpResponse response = httpClient.execute(httpPost); HttpEntity respEntity = response.getEntity(); String result = EntityUtils.toString(respEntity, DEFAULT_CHARSET); After successfully executed these codes, the result is a stripped string. I've tried using browser to test the url+param, it works fine and got all data. What's wrong with this code? Is there any parameters I need to specified?

  • Tile Engine: Entity location wrong

    - by Trizicus
    I've made a tile engine that has 30px by 30px. I've ran into a problem with an object for example. I've loaded an object 20px by 20px and when I do a collision check I have to use x/y position which is top left in Java2D. How can I do collision detection based on the entire object? This is relevant code: boolean checkCol() { int currentGridX = ship.getX()/30; int currentGridY = ship.getY()/30; if(test[currentGridX][currentGridY] == 0) return true; System.out.println("collision"); return false; }

  • A beginner's JSF question about form validation

    - by Nitesh Panchal
    Hello, I am having a form and many input elements in that. I want certain fields to be validated, so i keep validateLenth etc on those. And i want some fields to not be validated. For example, i have contact information and address information both on the same page. I want to treat contact information as one group. So if some fields are invalid they should not be submitted and address information to be independent of contact information. Thus, if address information is corrected it should be submitted. I have one form only on the page but two buttons, one for address and one for contact. Simply put :- What is the equivalent of validationGroup of Asp.Net in JSF?
