  • Freemarker - lack of special character in email subject template cause email content crash

    - by freakman
    im fighting with strange error. Im using seperate freemarker templates for mail subject and body. It is sent using org.springframework.mail.javamail.JavaMailSender. Only templates that contains some special swedish character works in my application ( yes you read right... not the other way). If I delete it my email content crashes. It contains then: MIME-Version: 1.0 Content-Type: text/html;charset=UTF-8 Content-Transfer-Encoding: 7bit .. html code here .. My freemarker.properties file locale=sv_SE classic_compatible=false number_format= date_format=yyyy-MM-dd time_format=HH:mm datetime_format=yyyy-MM-dd HH:mm output_encoding=UTF-8 url_escaping_charset=UTF-8 auto_import=spring.ftl as spring auto_include= default_encoding=UTF-8 localized_lookup=true strict_syntax=true whitespace_stripping=true template_update_delay=10 Ive tried to convert subject file with dos2unix tool. Using 'find -bi subject.ftl' show that encoding is us-ascii. With added special character - utf-8. This thing is suprisingly strange for me... //SOLUTION: use :set bomb and save file in vim.

  • How do I determine if a JDialog has children?

    - by Morinar
    I've got a custom window class that is a couple levels down extending a JDialog. We have windows that we create and sometimes we create new windows as children of existing windows using the constructor that takes a parent argument. I need to put some code somewhere in our custom class that does something different depending on whether not the window has children. I know of getParent(), etc, and I can see that I can loop through the components of the window, but for the life of me, I can't seem to figure out how to determine whether or not my current window has any child windows. Is there a way to do this? Any help is, as always, much appreciated.

  • Correct algorith for checking leap year

    - by Debanjan
    What will be the exact definition of leap year ? AFAIK "A year which is divisible by 4 is a leap year.But for century years' the years which are divisible by 400 is a leap year." But that definition makes 100, 200, 300, 400.... upto 1700 NOT LEAP years! But in Gregorian calender all of them are all leap year,check this out. You can also try "call 1700" in Linux to verify. So the correct algorithm foe leap year would be if ( (year % 4 == 0) && ( year <= 1700 || year % 100 != 0 || year % 400 == 0 )) printf("%d is a leap year.\n", year); else printf("%d is not a leap year.\n", year); But is this specific to Gregorian calender ? Even if that is the case why is it not mentioned here ? Regards, PS:The history of Gregorian callender seems interesting check out the September month of 1752.

  • Intent.getInt() doesn't work on ICS, but works on JB

    - by ObAt
    I use this code to send parameters when I start a new Activity: Intent inputForm = new Intent(getActivity(), InputForm.class); Bundle b = new Bundle(); b.putInt("item", Integer.parseInt(mItem.id)); //Your id inputForm.putExtras(b); //Put your id to your next Intent startActivity(inputForm); And I use this code for reading the parameters in the inputForm Activity: Bundle b = getIntent().getExtras(); if (b != null) { int value = b.getInt("item"); ID = value; } Toast.makeText(getApplication(), "MIJN ID:" + Integer.toString(ID), Toast.LENGTH_LONG).show(); When I run this code on my Samsung Tab 10.1 GT-P7510 ID is alsways 0, when I run the same code on my Galaxy S3 with JB the code just works fine. Can someone help me? Thanks in advance, ObAt

  • 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.

  • Can't read some attributes with SAX

    - by akappa
    Hi all, I'm trying to parse that document with SAX: <scxml version="1.0" initialstate="start" name="calc"> <datamodel> <data id="expr" expr="0" /> <data id="res" expr="0" /> </datamodel> <state id="start"> <transition event="OPER" target="opEntered" /> <transition event="DIGIT" target="operand" /> </state> <state id="operand"> <transition event="OPER" target="opEntered" /> <transition event="DIGIT" /> </state> </scxml> I read all the attributes well, except "initialstate" and "name"... I get the attributes with the startElement handler, but the size of the attribute list for scxml is zero. Why? How I can overcome that problem? Edit: public void startElement(String uri, String localName, String qName, Attributes attributes){ System.out.println(attributes.getValue("initialstate")); System.out.println(attributes.getValue("name")); } that, when parsing the first tag, doesn't work (prints "null" two times). In fact, attributes.getLength(); evaluates to zero. Thanks

  • May the FileInputStream.available foolish me?

    - by Tom Brito
    This FileInputStream.available() javadoc says: Returns an estimate of the number of remaining bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream. The next invocation might be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes. In some cases, a non-blocking read (or skip) may appear to be blocked when it is merely slow, for example when reading large files over slow networks. I'm not sure if in this check: if (new FileInputStream(xmlFile).available() == 0) can I rely that empty files will always return zero?

  • Are JSF 2.x ViewScoped Beans Thread Safe?

    - by Mark
    I've been googling for a couple hours on this issue to no eval. WELD docs and the CDI spec are pretty clear regarding thread safety of the scopes provided. For example: Application Scope - not safe Session Scope - not safe Request Scope - safe, always bound to a single thread Conversation Scope - safe (due to the WELD proxy serializing access from multiple request threads) I can't find anything on the View Scope defined by JSF 2.x. It is in roughly the same bucket as the Conversation Scope in that it is very possible for multiple requests to hit the scope concurrently despite it being bound to a single view / user. What I don't know is if the JSF implementation serializes access to the bean from multiple requests. Anyone have knowledge of the spec or of the Morraja/MyFaces implementations that could clear this up?

  • Swing: Scroll to bottom of JScrollPane, conditionally on current viewport location

    - by I82Much
    Hi all, I am attempting to mimic the functionality of Adium and most other chat clients I've seen, wherein the scrollbars advance to the bottom when new messages come in, but only if you're already there. In other words, if you've scrolled a few lines up and are reading, when a new message comes in it won't jump your position to the bottom of the screen; that would be annoying. But if you're scrolled to the bottom, the program rightly assumes that you want to see the most recent messages at all times, and so auto-scrolls accordingly. I have had a bear of a time trying to mimic this; the platform seems to fight this behavior at all costs. The best I can do is as follows: In constructor: JTextArea chatArea = new JTextArea(); JScrollPane chatAreaScrollPane = new JScrollPane(chatArea); // We will manually handle advancing chat window DefaultCaret caret = (DefaultCaret) chatArea.getCaret(); caret.setUpdatePolicy(DefaultCaret.NEVER_UPDATE); In method that handles new text coming in: boolean atBottom = isViewAtBottom(); // Append the text using styles etc to the chatArea if (atBottom) { scrollViewportToBottom(); } public boolean isAtBottom() { // Is the last line of text the last line of text visible? Adjustable sb = chatAreaScrollPane.getVerticalScrollBar(); int val = sb.getValue(); int lowest = val + sb.getVisibleAmount(); int maxVal = sb.getMaximum(); boolean atBottom = maxVal == lowest; return atBottom; } private void scrollToBottom() { chatArea.setCaretPosition(chatArea.getDocument().getLength()); } Now, this works, but it's janky and not ideal for two reasons. By setting the caret position, whatever selection the user may have in the chat area is erased. I can imagine this would be very irritating if he's attempting to copy/paste. Since the advancement of the scroll pane occurs after the text is inserted, there is a split second where the scrollbar is in the wrong position, and then it visually jumps towards the end. This is not ideal. Before you ask, yes I've read this blog post on Text Area Scrolling, but the default scroll to bottom behavior is not what I want. Other related (but to my mind, not completely helpful in this regard) questions: Setting scroll bar on a jscrollpane Making a JScrollPane automatically scroll all the way down. Any help in this regard would be very much appreciated.

  • JMS have javax.jms.InvalidDestinationException when client stop working

    - by Tran
    I use JMS for sending requests from a client to a server. My client sends a request to the server. While the server is working with my request, my client stops (network problem) before the server finishes. When the server is finished, it'll return to the client, but the server can't see the client which sent the request to server, at which point, the server will return an exception in log file. The exception is : javax.jms.InvalidDestinationException: Cannot publish to a deleted Destination: temp-queue://ID:PC0092-49463-1344231871819-0:0:9 [^] My question is: what do I need to do in this case? Can I catch or disable this exception? And how can I do it? (Sorry, If my english is not good.)

  • Finding the second highest number in array

    - by Richard Jackson
    I'm having difficulty to understand the logic behind the method to find the second highest number in array. The method used is to find the highest in the array but less than the previous highest (which has already been found). The thing that I still can't figure it out is why || highest_score == second_highest is necessary. For example I input three numbers: 98, 56, 3. Without it, both highest and second highest would be 98. Please explain. int second highest = score[0]; if (score[i] > second_highest && score[i] < highest_score || highest_score == second_highest) second_highest = score[i];

  • null != null - any ideas on how to re-arrange the code or prevent this?

    - by Alex
    Currently debugging, and found an if-statement which for no (I thought...) reason gave me an NPE, obviously for a reason. Which seemed to be that the statement turned out to be if(false && (null != null || null != Color)). if(destination != null && (destination.getPiece() != null || destination.getPiece().getColour() != pieceColour)) - the if-statement Both destination can be null and piece can be. The getColour() method returns an attribute of type Color from piece, which must be null if the piece is null. The piece at destination has a different pieceColour attribute then the one in the if-statement. Specifically, how do I re-arrange (destination.getPiece() != null) ?

  • Create user variable in Intellij File Template

    - by Matt Broekhuis
    I am trying to use Intellij's file templates (not live templates) to help mitigate how much boilerplate code I use when making Services, daos, and their interfaces. I am able to use all the system defined variables just fine, such as ${PACKAGE_NAME} What I want though, is to be able to use my own variable names, like ${MY_USER_INPUT} however, when i do this like above, I get an error The documentation says : It is also possible to specify arbitrary number of custom variables in format ${<VARIABLE_NAME>}. and then Intellij is supposed to prompt the user for the value. However, this just plain doesn't work for me. What am I missing?

  • Setting up ehcache replication - what multicast settings do I need?

    - by Darren Greaves
    I am trying to set up ehcache replication as documented here: http://ehcache.sourceforge.net/EhcacheUserGuide.html#id.s22.2 This is on a Windows machine but will ultimately run on Solaris in production. The instructions say to set up a provider as follows: <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory" properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1, multicastGroupPort=4446, timeToLive=32"/> And a listener like this: <cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" properties="hostName=localhost, port=40001, socketTimeoutMillis=2000"/> My questions are: Are the multicast IP address and port arbitrary (I know the address has to live within a specific range but do they have to be specific numbers)? Do they need to be set up in some way by our system administrator (I am on an office network)? I want to test it locally so am running two separate tomcat instances with the above config. What do I need to change in each one? I know both the listeners can't listen on the same port - but what about the provider? Also, are the listener ports arbitrary too? I've tried setting it up as above but in my testing the caches don't appear to be replicated - the value added in one tomcat's cache is not present in the other cache. Is there anything I can do to debug this situation (other than packet sniffing)? Thanks in advance for any help, been tearing my hair out over this one!

  • Swing code in sockets

    - by asb
    I am learning swings for making GUI. I was thinking which is the best possible way in case of socket with swings. 1. The whole swing code goes in the server file. All the handlers and logic in on server side. Client only create socket. 2. The server have logic part. The code for the swing to display interface goes on client side. Client Creates stream to send / rec. data from server. Whch is the good way out of 2 ?
