• JDOM 1.1: hyphen is not a valid comment character

  - by Stefan Kendall

  I'm using tagsoup to clean some HTML I'm scraping from the internet, and I'm getting the following error when parsing through pages with comments: The data "- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - " is not legal for a JDOM comment: Comment data cannot start with a hyphen. I'm using JDOM 1.1, and here's the code that does the actual cleaning: SAXBuilder builder = new org.jdom.input.SAXBuilder("org.ccil.cowan.tagsoup.Parser"); // build // Don't check the doctype! At our usage rate, we'll get 503 responses // from the w3. builder.setEntityResolver(dummyEntityResolver); Reader in = new StringReader(str); org.jdom.Document doc = builder.build(in); String cleanXmlDoc = new org.jdom.output.XMLOutputter().outputString(doc); Any idea what's going wrong, or how to fix this? I need to be able to parse pages with long comment strings of <!--------- data ------------>

• UriBuilder incorrectly encoding Query Parameters value ?

  - by Fred

  Lets consider the following code sample where a path and single parameter are encoded... Parameter name: "param" Parameter value: "foo/bar?aaa=bbb&ccc=ddd" (happens to be a url with query parameters) String test = UriBuilder.fromPath("https://dummy.com"). queryParam("param", "foo/bar?aaa=bbb&ccc=ddd"). build().toURL().toString(); The encoded URL string returned is: "https://dummy.com?param=foo/bar?aaa%3Dbbb&ccc%3Dddd" Is this correct ? Should not the character "&" (and may be even "?") be encoded in the parameter value string ? Would not the URL produced be interpreted as follow: One first parameter, name="param", value = "ar?aaa%3Dbbb" followed by a second parameter, name="ccc%3Dddd", without value.

• How to keep the highlight border of a JComponent, when custom border is set

  - by Frederik Wordenskjold

  I have a JTextField, where I've set some custom properties: nameField.setPreferredSize(new Dimension(275,40)); nameField.setBackground(bgColor); nameField.setForeground(txtColor); nameField.setFont(new Font("HelveticaNeue",Font.PLAIN,22)); nameField.setBorder(BorderFactory.createLineBorder(Color.WHITE, 2)); When the component has focus, there is no highlight shown around the field. On a Mac, it is usually a blue glowing rectangle, indicating that this component has focus. If I comment out the nameField.setBorder(...), the highlight reappears. How do I keep the highlight, but also my custom border!? Basically, I just want the highlight-border to show when the component has focus, and no border when the component is unfocused.

• How to save file using JFileChooser??

  - by Lokesh Kumar

  Hi, I have a method in my application called "Save as" which Saves the image of my application on computer my into a file. I used the JFileChooser to let the users choose their desired location for saving the file. The problem is unless user explicitly types in the file format, it saves the file with no extension. How can I have formats like jpg, png in the File Type drop down menu. and, how can i get extension from the File Type drop menu for saving my image file. ImageIO.write(image,extension,file);

• httpClient proxy support in apache commons 3.1

  - by user1173339

  I am using apache commons 3.1 to implement httpClient with proxy support. I am trying to connect to a remote host through proxy. The proxy server is configured without any authentication, however the the remote host is configured with authentication. When I am passing the proxy parameters through properties file, it gives warning while execution: WARN - Required proxy credentials not available for BASIC @xx.xx.xx.xx WARN - Preemptive authentication requested but no default proxy credentials availble But the execution goes ahead. On the other hand when I am passing the proxy parameters through the JVM arguments then the again the same warning is given and the execution is stopped. Is there any specific reason for this behavior? Is there any difference in passing the proxy parameters through properties file and through JVM arg? Here is the code: if(System.getProperty("http.proxyHost") != null && System.getProperty("http.proxyPort") != null) { httpClient.getHostConfiguration().setProxy(System.getProperty("http.proxyHost"), Integer.parseInt(System.getProperty("http.proxyPort"))); } else if(AMXAdminTask.props.getProperty("http.proxyHost") != null && AMXAdminTask.props.getProperty("http.proxyPort") != null) { httpClient.getHostConfiguration().setProxy(Propfile.props.getProperty("http.proxyHost"), Integer.parseInt(Propfile.props.getProperty("http.proxyPort"))); }

• Blackberry read local properties file in project

  - by Dachmt

  Hi, I have a config.properties file at the root of my blackberry project (same place as Blackberry_App_Descriptor.xml file), and I try to access the file to read and write into it. See below my class: public class Configuration { private String file; private String fileName; public Configuration(String pathToFile) { this.fileName = pathToFile; try { // Try to load the file and read it System.out.println("---------- Start to read the file"); file = readFile(fileName); System.out.println("---------- Property file:"); System.out.println(file); } catch (Exception e) { System.out.println("---------- Error reading file"); System.out.println(e.getMessage()); } } /** * Read a file and return it in a String * @param fName * @return */ private String readFile(String fName) { String properties = null; try { System.out.println("---------- Opening the file"); //to actually retrieve the resource prefix the name of the file with a "/" InputStream is = this.getClass().getResourceAsStream(fName); //we now have an input stream. Create a reader and read out //each character in the stream. System.out.println("---------- Input stream"); InputStreamReader isr = new InputStreamReader(is); char c; System.out.println("---------- Append string now"); while ((c = (char)isr.read()) != -1) { properties += c; } } catch (Exception e) { } return properties; } } I call my class constructor like this: Configuration config = new Configuration("/config.properties"); So in my class, "file" should have all the content of the config.properties file, and the fileName should have this value "/config.properties". But the "name" is null because the file cannot be found... I know this is the path of the file which should be different, but I don't know what i can change... The class is in the package com.mycompany.blackberry.utils Thank you!

• Defining jUnit Test cases Correctly

  - by Epitaph

  I am new to Unit Testing and therefore wanted to do some practical exercise to get familiar with the jUnit framework. I created a program that implements a String multiplier public String multiply(String number1, String number2) In order to test the multiplier method, I created a test suite consisting of the following test cases (with all the needed integer parsing, etc) @Test public class MultiplierTest { Multiplier multiplier = new Multiplier(); // Test for 2 positive integers assertEquals("Result", 5, multiplier.multiply("5", "1")); // Test for 1 positive integer and 0 assertEquals("Result", 0, multiplier.multiply("5", "0")); // Test for 1 positive and 1 negative integer assertEquals("Result", -1, multiplier.multiply("-1", "1")); // Test for 2 negative integers assertEquals("Result", 10, multiplier.multiply("-5", "-2")); // Test for 1 positive integer and 1 non number assertEquals("Result", , multiplier.multiply("x", "1")); // Test for 1 positive integer and 1 empty field assertEquals("Result", , multiplier.multiply("5", "")); // Test for 2 empty fields assertEquals("Result", , multiplier.multiply("", "")); In a similar fashion, I can create test cases involving boundary cases (considering numbers are int values) or even imaginary values. 1) But, what should be the expected value for the last 3 test cases above? (a special number indicating error?) 2) What additional test cases did I miss? 3) Is assertEquals() method enough for testing the multiplier method or do I need other methods like assertTrue(), assertFalse(), assertSame() etc 4) Is this the RIGHT way to go about developing test cases? How am I "exactly" benefiting from this exercise? 5)What should be the ideal way to test the multiplier method? I am pretty clueless here. If anyone can help answer these queries I'd greatly appreciate it. Thank you.

• MINA: Performing synchronous write requests / read responses

  - by Matt Huggins

  I'm attempting to perform a synchronous write/read in a demux-based client application with MINA 2.0 RC1, but it seems to get stuck. Here is my code: public boolean login(final String username, final String password) { // block inbound messages session.getConfig().setUseReadOperation(true); // send the login request final LoginRequest loginRequest = new LoginRequest(username, password); final WriteFuture writeFuture = session.write(loginRequest); writeFuture.awaitUninterruptibly(); if (writeFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // retrieve the login response final ReadFuture readFuture = session.read(); readFuture.awaitUninterruptibly(); if (readFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // stop blocking inbound messages session.getConfig().setUseReadOperation(false); // determine if the login info provided was valid final LoginResponse loginResponse = (LoginResponse)readFuture.getMessage(); return loginResponse.getSuccess(); } I can see on the server side that the LoginRequest object is retrieved, and a LoginResponse message is sent. On the client side, the DemuxingProtocolCodecFactory receives the response, but after throwing in some logging, I can see that the client gets stuck on the call to readFuture.awaitUninterruptibly(). I can't for the life of me figure out why it is stuck here based upon my own code. I properly set the read operation to true on the session config, meaning that messages should be blocked. However, it seems as if the message no longer exists by time I try to read response messages synchronously. Any clues as to why this won't work for me?

• Variable cannot be resolved

  - by Devel

  Hi, I am trying to create an item list, diffrent for each i and j variable. My code is: if (i == 0) { if (j == 0) { final CharSequence[] items = {"4:45", "5:00"} } else if (j == 1) { final CharSequence[] items = {"4:43", "4:58"} } else if (j == 2) { final CharSequence[] items = {"4:41", "4:56"} } else { final CharSequence[] items = {"4:38", "4:53"} } ... new AlertDialog.Builder(this) .setTitle("Hours") .setItems(items, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialoginterface, int i) { // getStation(i); } }) .show(); } I get an error in the line .setItems(items,: items cannot be resolved I think that the compiler thinks that the CharSequence[] items may not be initialised or something... How can I make this programme run?

• Jalopy comments indentation

  - by Neil Wightman

  Hi All. We use jalopy to format our code to the sun standard (well 99%). I have 1 issue with it. It keeps moving comments to the right of the line. E.g // Panel "JPanel.border", new LazyValue(packageName + "PanelBorder"), //frozen // Button "Button.background", new ColorUIResource(251, 251, 251), //frozen "Button.foreground", new ColorUIResource(0, 0, 0), //frozen But jalopy always moves the // Button to the far right. // Panel "JPanel.border", new LazyValue(packageName + "PanelBorder"), //frozen // Button "Button.background", new ColorUIResource(251, 251, 251), //frozen "Button.foreground", new ColorUIResource(0, 0, 0), //frozen Is there any way to stop this? Thanks Neil

• Perf4j Not Logging to Separate File

  - by Jehud

  I setup some stop watch calls in my code to measure some code blocks and all the messages are going into my primary log and not into the timing log. The perfStats.log file gets created just fine but all the messages go to the root log which I didn't think was supposed to happen according to the docs I've read. Is there something obvious I'm missing here? Example log4j.xml <!-- This file appender is used to output aggregated performance statistics --> <appender name="fileAppender" class="org.apache.log4j.FileAppender"> <param name="File" value="perfStats.log"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%m%n"/> </layout> </appender> <!-- Loggers --> <!-- The Perf4J logger. Note that org.perf4j.TimingLogger is the value of the org.perf4j.StopWatch.DEFAULT_LOGGER_NAME constant. Also, note that additivity is set to false, which is usually what is desired - this means that timing statements will only be sent to this logger and NOT to upstream loggers. --> <logger name="org.perf4j.TimingLogger" additivity="false"> <level value="INFO"/> <appender-ref ref="CoalescingStatistics"/> </logger> <root> <priority value="info"/> <appender-ref ref="STDOUT-DEBUG"/> </root>

• Pentaho - Reporting Tool - Is the .prpt file (report template file) contains datasource information

  - by Yatendra Goel

  I am new Pentaho Reporting Tool. I have the following question: When I created a report using Pentaho Report Designer, it output a report file having .prpt extension. After that I found an example on internet where the following code were used to display the report in html format:| protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ResourceManager manager = new ResourceManager(); manager.registerDefaults(); String reportPath = "file:" + this.getServletContext().getRealPath("sampleReport.prpt"); try { Resource res = manager.createDirectly(new URL(reportPath), MasterReport.class); MasterReport report = (MasterReport) res.getResource(); HtmlReportUtil.createStreamHTML(report, response.getOutputStream()); } catch (Exception e) { e.printStackTrace(); } } And the report got printed successfully. So as we haven't specified any datasource information here, I think that the .prpt file contains that information in it. If that's true than Isn't Jasper is better Reporting tool than Pentaho because when we display Jasper reports, we have to provide datasource details also so in that way our report is flexible and is not bound to any particular database.

• Parsing a string, Grammar file.

  - by defn

  How would I separate the below string into its parts. What I need to separate is each < Word including the angle brackets from the rest of the string. So in the below case I would end up with several strings 1. "I have to break up with you because " 2. "< reason " (without the spaces) 3. " . But Let's still " 4. "< disclaimer " 5. " ." I have to break up with you because <reason> . But let's still <disclaimer> . below is what I currently have (its ugly...) boolean complete = false; int begin = 0; int end = 0; while (complete == false) { if (s.charAt(end) == '<'){ stack.add(new Terminal(s.substring(begin, end))); begin = end; } else if (s.charAt(end) == '>') { stack.add(new NonTerminal(s.substring(begin, end))); begin = end; end++; } else if (end == s.length()){ if (isTerminal(getSubstring(s, begin, end))){ stack.add(new Terminal(s.substring(begin, end))); } else { stack.add(new NonTerminal(s.substring(begin, end))); } complete = true; } end++;

• How can I set partial text color in JTextArea

  - by ComputerJy

  I want to set color for specific lines in the text area. What I've found so far, was the following // Declarations private final DefaultStyledDocument document; private final MutableAttributeSet homeAttributeSet; private final MutableAttributeSet awayAttributeSet; // Usage in the form constructor jTextAreaLog.setDocument(document); homeAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(homeAttributeSet, Color.blue); StyleConstants.setItalic(homeAttributeSet, true); awayAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(awayAttributeSet, Color.red); // Setting the style of the last line final int start = jTextAreaLog.getLineStartOffset(jTextAreaLog.getLineCount() - 2); final int length = jTextAreaLog.getLineEndOffset(jTextAreaLog.getLineCount() - 1) - start; document.setCharacterAttributes(start, length, awayAttributeSet, true); But this is not working. What am I doing wrong?

• how to programmatically create menu items while creating nodes?

  - by sprugman

  I'm creating some nodes programmatically, thus: foreach ($titles as $t) { $n = new stdClass(); $n->type = 'myType'; $n->uid = 1; $n->title = $t; $menu = array(); $menu['link_title'] = $t; $menu['menu_name'] = 'primary-links'; // this attempt at placing the menu item in a particular place in the // menu hierarchy didn't work: $menu['parent'] = 'primary-links:867'; $menu['depth'] = 3; $menu['p1'] = '580'; $menu['p2'] = '867'; $n->menu = $menu; node_save($n); } I've got a menu structure like this: primary-links Parent 1 Child 1 Child 2 Parent 2 Child 3 I want the new menu items to appear as children of Child 3. I was able to create menu items at the same time as the nodes, and they appeared in the correct menu, but not in the correct place in the hierarchy. What am I missing?

• Retrieve data from .dat file.

  - by Zach

  We have an application which requires us to read data from a file (.dat) dynamically using deserialization. We are actually getting first object and it throws null pointer exception when we are accessing other objects using a "for" loop. File file=null; FileOutputStream fos=null; BufferedOutputStream bos=null; ObjectOutputStream oos=null; try{ file=new File("account4.dat"); fos=new FileOutputStream(file,true); bos=new BufferedOutputStream(fos); oos=new ObjectOutputStream(bos); oos.writeObject(m); System.out.println("object serialized"); amlist=new MemberAccountList(); oos.close(); } catch(Exception ex){ ex.printStackTrace(); } Reading objects: try{ MemberAccount m1; file=new File("account4.dat");//add your code here fis=new FileInputStream(file); bis=new BufferedInputStream(fis); ois=new ObjectInputStream(bis); System.out.println(ois.readObject()); while(ois.readObject()!=null){ m1=(MemberAccount)ois.readObject(); System.out.println(m1.toString()); }/mList.addElement(m1); // Here we have the issue throwing null pointer exception Enumeration elist=mList.elements(); while(elist.hasMoreElements()){ obj=elist.nextElement(); System.out.println(obj.toString()); }/ } catch(ClassNotFoundException e){ } catch(EOFException e){ System.out.println("end"); } catch(Exception ex){ ex.printStackTrace(); }

• Google Maps v3 InfoWindow Too Wide

  - by ryan

  In Google Maps v3, I can't seem to get my infoWindow to a width smaller than 200px. Here is the code I'm using: var latlng = new google.maps.LatLng(-34.397, 150.644); var myOptions = { zoom: 15, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var myMap = new google.maps.Map(document.getElementById("map_canvas"), myOptions); var gmarker = new google.maps.Marker({position: latLng,title:'Example'} ); var infoWindow = new google.maps.InfoWindow(); infoWindow.setOptions({maxWidth: 110}); window_content = '<div style="width:110px;height:110px;">Test</div>'; infoWindow.setContent(window_content); infoWindow.open(myMap, gmarker); Is there a way to get the infoWindow more narrow? Or am I stuck with a minimum width?
