• How to putExtra() in Searchable Dictionary Example

  - by sirlunchalot

  Hi, based on the Searchable Dictionary sample I tried to put extra data to a different activity. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Spinner distance = (Spinner) findViewById(R.id.distanceSpinner); ArrayAdapter<CharSequence> adapterDistance = ArrayAdapter.createFromResource( this, R.array.distance, android.R.layout.simple_spinner_item); adapterDistance.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); distance.setAdapter(adapterDistance); Intent intent = getIntent(); if (Intent.ACTION_VIEW.equals(intent.getAction())) { // handles a click on a search suggestion; launches activity to show word mapIntent = new Intent(this, Map.class); mapIntent.setData(intent.getData()); mapIntent.putExtra("Distance", distance.getSelectedItemPosition()); startActivity(mapIntent); finish(); } } In my Map Class Distance is always zero because distance.getSelectedItemPostion() gets the initialized value. How can I putExtra data with a click on a search suggestion? Thanks

• How can I change the arrow style in a JComboBox

  - by Stephane Grenier

  Let's say I want to use a custom image for the arrow in JComboBox, how can I do this? I understand it's possible using the synth xml files, or maybe even UIManager.put(...), but I don't know how. All I want to do at this time is change the arrow image to something else, either programatically or even just overriding the image it uses. How exactly can I do this?

• Final enum in Thread's run() method

  - by portoalet

  Hi, Why is the Elvis elvis definition has to be final to be used inside the Thread run() method? Elvis elvis = Elvis.INSTANCE; // ----> should be final Elvis elvis = Elvis.INSTANCE elvis.sing(4); Thread t1 = new Thread( new Runnable() { @Override public void run() { elvis.sing(6); // --------> elvis has to be final to compile } } ); public enum Elvis { INSTANCE(2); Elvis() { this.x = new AtomicInteger(0); } Elvis(int x){ this.x = new AtomicInteger(x); } private AtomicInteger x = new AtomicInteger(0); public int getX() { return x.get(); } public void setX(int x) {this.x = new AtomicInteger(x);} public void sing(int x) { this.x = new AtomicInteger(x); System.out.println("Elvis singing.." + x); } }

• 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 ); } } }

• Getting a JFrame's actual current location

  - by Ian Fellows

  Hello community, I am trying to create a (child) JFrame which slides out from underneath one side of a second (parent) JFrame. The goal is to then have the child follow the parent around when it is moved, and respond to resizing events. This is somewhat related to this question. I have tried using a ComponentListener, but with this method the child only moves once the parent has come to a stop, whereas I would like the child to move as the parent is dragged around the screen. Another option I attempted was to start a new refresher thread that continually updated the child's location using getLocation() or getLocationOnScreen(), but the lag was the same as with ComponentListener. Is there a way to get the true actual location of a JFrame even in the midst of a drag? or if not, is there a way to get the effect of a sheet sliding out from underneath and following the Frame around?

• Text input for multi-valued attribute

  - by Sean

  I need to create an input form that will allow a user to enter any number of values for a particular attribute. I've tried several approaches, all of which seem to have various levels of failure. The latest model bean looks something like: public class Product { private String name; private String[] tags; ...accessors... } The input fields look something like: <h:inputText id="name" value="#{product.name}"></h:inputText> <h:inputText id="tag0" value="#{product.tag[0]}"></h:inputText> My plan was to allow the user is to use javascript to add additional form fields as needed. This type of setup gives me a 'Target Unreachable' error. What am I missing? I am using JSF 1.1 on WebSphere 6.1

• Is there a JVM aimed at debugging concurrent software?

  - by Roger Wernersson

  I've used Concurrent Pascal, a tool which helps debug concurrent algorithms because when it runs your code, it randomizes which thread to swap to at every possible step, trying out as many paths as possible. Is there a JVM that can do this?

• How to determine whether a spread-sheet cell contains a date, or a real number?

  - by Everyone

  When a cell in a spreadsheet contains a simple date (mm/dd/yyyy) the poi API flags the cell-type as 'numeric'. This is probably because spreadsheets ( IMO ) historically recognize only strings and real numbers. It is possible to hard-code the cell-index, and use it conditionally to call 'getDateCellValue'. But this feels like a hack. What other ways are there in the poi API to determine whether the content in a cell is a Date rather than a real number?

• How to call SOAP web service in Android

  - by BobbyShaftoe

  I am having a lot of trouble finding good information on how to call a standard SOAP/WSDL web service with Android. All I've been able to find are either very convoluted documents and references to "kSoap2" and then some bit about parsing it all manually with SAX. OK, that's fine, but it's 2008 so I figured there should be some good library for calling standard web services. The web service is just basically one created in NetBeans. I would like to have IDE support for generating the plumbing classes. I just need the easiest/most-elegant way to contact a WSDL based web service from an Android based phone.

• Would you take a paycut [closed]

  - by arinte

  I make 90K doing JEE5 (it is open I can use any tech I want which is nice) but don't like what I am doing to because it is too hw related. I have an offer for 88K and a bonus that would be 10% (almost assured) that I would guess would be paid in the 4th quarter. It is a j2ee, supposed to be moving to jee5 and there are no hw dependencies (banking type work). I think I would be interested, but I have always been told you do not take a pay cut and don't move laterally (go to another job at the same pay). I have been on other interviews but this is the only one that has panned out. Also with the current job there is 401k match, but with the new one there is 401k also and a pension. What would you do?

• How to prevent the other threads from accessing a method when one thread is accessing a method?

  - by geeta

  I want to search for a string in 10 files and write the matching lines to a single file. I wrote the matching lines from each file to 10 output files(o/p file1,o/p file2...) and then copied those to a single file using 10 threads. But the output single file has mixed output(one line from o/p file1,another line from o/p file 2 etc...) because its accessed simultaneously by many threads. If I wait for all threads to complete and then write the single file it will be much slower. I want the output file to be written by one thread at a time. What should i do? My source code:(only writing to single file method) public void WriteSingle(File output_file,File final_output) throws IOException { synchronized(output_file){ System.out.println("Writing Single file"); FileOutputStream fo = new FileOutputStream(final_output,true); FileChannel fi = fo.getChannel(); FileInputStream fs = new FileInputStream(output_file); FileChannel fc = fs.getChannel(); int maxCount = (64 * 1024 * 1024) - (32 * 1024); long size = fc.size(); long position = 0; while (position < size) { position += fc.transferTo(position, maxCount, fi); } } }

• JPQL: What kind of objects contains a result list when querying multiple columns?

  - by Bunkerbewohner

  Hello! I'm trying to do something which is easy as pie in PHP & Co: SELECT COUNT(x) as numItems, AVG(y) as average, ... FROM Z In PHP I would get a simple array like [{ numItems: 0, average: 0 }] which I could use like this: echo "Number of Items: " . $result[0]['numItems']; Usually in JPQL you only query single objects or single columns and get Lists types, for example List or List. But what do you get, when querying multiple columns?
