  • Sound Effects/Manipulation?

    - by Adam
    Hello, I am creating an android app that basically records an applies an "Effect" on the audio track then plays it back. I got my app to record an play back but I am stuck an not sure where do go from here. I have been Googling for days now trying to find a open source audio library or some way to change the audio after I record it. I currently have it setup to play back using SoundPool an I't lets me speed up an slow down the audio. I would like to do things like change pitch an add echo etc. I will appreciate any responses because I am totally stumped right now. Thanks Adam

  • Missing ant-javamail.jar file on Macintosh

    - by Ken
    I've been running the built-in Ant from the command line on a Macintosh (10.5.5) and have run into some trouble with the Mail task. Running the Mail task produces the following message: [mail] Failed to initialise MIME mail: org.apache.tools.ant.taskdefs.email.MimeMailer This is most likely due to a missing ant-javamail.jar file in the /usr/share/ant/lib directory. I see a "ant-javamail-1.7.0.pom" file in this directory but not the appropriate jar file. Anyone know why this jar file might be missing and what the best way to resolve the problem is?

  • Sort ArrayList alphabetically

    - by relyt
    I'm trying to find all permutations of a string and sort them alphabetically. This is what I have so far: public class permutations { public static void main(String args[]) { Scanner s = new Scanner(System.in); System.out.print("Enter String: "); String chars = s.next(); findPerms("", chars); } public static void findPerms(String mystr, String chars) { List<String> permsList = new ArrayList<String>(); if (chars.length() <= 1) permsList.add(mystr + chars); //System.out.print(mystr + chars + " "); else for (int i = 0; i < chars.length(); i++) { String newString = chars.substring(0, i) + chars.substring(i + 1); findPerms(mystr + chars.charAt(i), newString); } Collections.sort(permsList); for(int i=0; i<permsList.size(); i++) { System.out.print(permsList.get(i) + " "); } } } IF I enter a string "toys" I get: toys tosy tyos tyso tsoy tsyo otys otsy oyts oyst osty osyt ytos ytso yots yost ysto ysot stoy styo soty soyt syto syot What am I doing wrong. How can I get them in alphabetical order? Thanks!

  • FindBugs controversial description

    - by Tom Brito
    Am I understanding it wrong, or is the description wrong? Equals checks for noncompatible operand (EQ_CHECK_FOR_OPERAND_NOT_COMPATIBLE_WITH_THIS) This equals method is checking to see if the argument is some incompatible type (i.e., a class that is neither a supertype nor subtype of the class that defines the equals method). For example, the Foo class might have an equals method that looks like: public boolean equals(Object o) { if (o instanceof Foo) return name.equals(((Foo)o).name); else if (o instanceof String) return name.equals(o); else return false; This is considered bad practice, as it makes it very hard to implement an equals method that is symmetric and transitive. Without those properties, very unexpected behavoirs are possible. From: http://findbugs.sourceforge.net/bugDescriptions.html#EQ_CHECK_FOR_OPERAND_NOT_COMPATIBLE_WITH_THIS The description says that the Foo class might have an equals method like that, and after it says that "This is considered bad practice". I'm not getting the "right way".. How should the following method be to be right? @Override public boolean equals(Object obj) { if (obj instanceof DefaultTableModel) return model.equals((DefaultTableModel)obj); else return false; }

  • oracle clob insertion problem in spring

    - by haluk
    Hi, I want to insert CLOB value into my Oracle database and here is the what I could do. I got this exception while inserting operation "ORA-01461: can bind a LONG value only for insert into a LONG column". Would someone able to tell me what should I do? Thanks.

  • Android ListView appears empty, but contains objects

    - by Lethjakman
    I'm having a really odd problem with my android listview. The listview is inside of a fragment, everything's compiling and I'm no longer getting a nullpointer error, but the listview is appearing empty. Even though it's appearing empty, the log is stating that the listview has 385 objects. I can't figure out why it's empty. I do get a blue fragment, and the listview is populated. Any ideas? How I set the adapter: ActivePackages = getList(); LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); LinearLayout mContainer = (LinearLayout) inflater.inflate(R.layout.tab_frag1_layout, null); ListView activeList = (ListView) mContainer.findViewById(R.id.activelist); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, ActivePackages); Log.i("valueof activeList",String.valueOf(activeList.getCount())); //returns 0 activeList.setAdapter(adapter); adapter.notifyDataSetChanged(); Log.i("valueof activeList",String.valueOf(activeList.getCount())); //returns 385. This is the xml for the fragment: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ListView android:id="@+id/activelist" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#0073fd"> </ListView> </LinearLayout>

  • JAXB: @XmlTransient on third-party or external super class

    - by Phil
    Hi, I need some help regarding the following issue with JAXB 2.1. Sample: I've created a SpecialPerson class that extends a abstract class Person. Now I want to transform my object structure into a XML schema using JAXB. Thereby I don't want the Person XML type to appear in my XML schema to keep the schema simple. Instead I want the fields of the Person class to appear in the SpecialPerson XML type. Normally I would add the annotation @XmlTransient on class level into the Person code. The problem is that Person is a third-party class and I have no possibility to add @XmlTransient here. How can I tell JAXB that it should ignore the Person class without annotating the class. Is it possible to configure this externally somehow? Have you had the same problem before? Any ideas what the best solution for this problem would be?

  • JVM (embarrasingly) parallel processing libraries/tools

    - by Winterstream
    I am looking for something that will make it easy to run (correctly coded) embarrassingly parallel JVM code on a cluster (so that I can use Clojure + Incanter). I have used Parallel Python in the past to do this. We have a new PBS cluster and our admin will soon set up IPython nodes that use PBS as the backend. Both of these systems make it almost a no-brainer to run certain types of code in a cluster. I made the mistake of using Hadoop in the past (Hadoop is just not suited to the kind of data that I use) - the latency made even small runs execute for 1-2 minutes. Is JPPF or Gridgain better for what I need? Does anyone here have any experience with either? Is there anything else you can recommend?

  • How to limit JTextArea max Rows and Coloums?

    - by Billbo bug
    I am using JTextArea in JScrollPane I want to limit the maximum number of lines possible and the maximum chars in each line. I need that the string will be exactly like on the screen, each line will end with '\n' (if there another line after it) and the user will be able to insert only X lines and Y chars in each line. I tried to limit the lines but i don't know exactly how many lines do i have because of the line wrapping, The line wrapping is starting new line visualy on the screen(because of the width of the JTextArea) but in the string of the component it is really the same line with no '\n' to indicate new line. I do not have an idea how to limit the max chars in each line while typing. There are 2 stages: The typing of the string- keep that the user will not be able to type more then X lines and Y chars in each line. (even if the line wrap only visualy or the user typed '/n') Insert the string to the DB- after cliking 'OK' convert the string that every line will end with "/n" even if the user did not typed it and the line was wrapped only visualy. There are few problems if i will count the chars in the line and insert '/n' in the end of the line, thats why i decided to do it in two stages. In the first stage ehile the user is typing i would rather only limit it visualy and force line wrpping or something similar. Only in the second stage when i save string i will add the '/n' even if the user did not typed it in the end of the lines! Does anyone have an idea? I know that i will have to use DocumentFilter OR StyledDocument. Here is sample code that limit only the lines to 3:(but not the chars in row to 19) private JTextArea textArea ; textArea = new JTextArea(3,19); textArea .setLineWrap(true); textArea .setDocument(new LimitedStyledDocument(3)); JScrollPane scrollPane = new JScrollPane(textArea public class LimitedStyledDocument extends DefaultStyledDocument /** Field maxCharacters */ int maxLines; public LimitedStyledDocument(int maxLines) { maxCharacters = maxLines; } public void insertString(int offs, String str, AttributeSet attribute) throws BadLocationException { Element root = this.getDefaultRootElement(); int lineCount = getLineCount(str); if (lineCount + root.getElementCount() <= maxLines){ super.insertString(offs, str, attribute); } else { Toolkit.getDefaultToolkit().beep(); } } /** * get Line Count * * @param str * @return the count of '\n' in the String */ private int getLineCount(String str){ String tempStr = new String(str); int index; int lineCount = 0; while (tempStr.length() > 0){ index = tempStr.indexOf("\n"); if(index != -1){ lineCount++; tempStr = tempStr.substring(index+1); } else{ break; } } return lineCount; } }

  • How can I update information in an Android Activity from a background Service

    - by tmm
    Hello, I am trying to create a simple Android application that has a ActivityList of information, when the application starts, I plan to start a Service that will be constantly calculating the data (it will be changing) and I want the ActivityList to be in sync with the data that the service is calculating for the life of the app. How can I set up my Activity to be listening to the Service? Is this the best way to approach this problem? For example, if you imagine a list of stock prices - the data would be being changed regularly and need to be in sync with the (in my case) Service that is calculating/fetching the data constantly. Thanks in advance

  • jna call to kernel32.CreateToolhelp32Snapshot in shutdown hook crashes the VM

    - by jumar
    If a thread sets a shutdown hook using Runtime.getRuntime().addShutdownHook(); calls via jna the method: kernel32.CreateToolhelp32Snapshot (0x00000002, 0) it crashes the VM. If I call the same method in the WindowListener.windowClosing() hook, the call does not crashes the VM. Any idea why? I can post part of the VM crash error report if it could be of any use. edit: see the VM crash report on pastebin

  • No long-running conversations - IllegalArgumentException: Stack must not be null

    - by Markos Fragkakis
    Hi all, I have a very simple application with just 2 pages on WebLogic 10.3.2 (11g), Seam 2.2.0.GA. I have a command button in each, which makes a redirect-after-post to the other. This works well, as I see the URL of the current page I am seeing in the address bar. BUT, even though I have no long-running conversations defined, after a random number of clicks, and - I think - after a random number of seconds (~10s - 60s) I get the lovely exception at the end of this post. Now, if I have understood how temporary conversations work when redirecting this happens: When I first see my application, the url is http://localhost:7001/myapp When I click the button in pageA.xhtml, I end up in "pageB.xhtml?cid=26". This is normal because Seam extends the temporary conversation of the first request to last until the renderResponse phase of the redirect. So, it uses the cid (Conversation Id) of the extended temporary conversation to find any propagated parameters. When I click the button in pageB.xhtml, I end up in pageA.xhtml?cid=26 The same cid was given to the new extended temporary conversation. This is normal because the conversation ended at the end of the previous redirect-after-post, and not the number 26 is free to use as a cid. Is this all correct? If yes, why does this happen: If I re-type the applications home address (showing pageA) and re-click, I end up in pageB.xhtml?cid=29, which is a different number than 26. But 26 has ended after the previous RenderResponse phase, befire I re-types the url. Why is it not used instead of 29? So, to sup up, 2 questions: Why do I get the exception, even though I have not started any long-running conversations? What happens exactly with the cid? On what basis does it change? Cheers,

  • Assigning outcome of another JSTL tag as value of one JSTL tag

    - by NoozNooz42
    I've got this, which is working: <c:choose> <c:when test="${sometest}"> Hello, world! </c:when> <c:otherwise> <fmt:message key="${page.title}" /> </c:otherwise> </c:choose> And I want to change it to this: <c:choose> <c:when test="${sometest}"> <c:set var="somevar" scope="page" value="Hello, world!"/> </c:when> <c:otherwise> <c:set var="somevar" scope="page" value="<fmt:message key="${page.title}">" </c:otherwise> </c:choose But of course the following line ain't correct: <c:set var="somevar" scope="page" value="<fmt:message key="${page.title}">" How can I assign to the somevar variable the string resulting from a call to fmt:message?

  • NetBeans and Eclipse-like "run configurations"

    - by auramo
    Is it possible to create anything similar to Eclipse's "run configurations" in NetBeans? I am working on a huge project which is currently not divided into any subprojects in Eclipse. There are in fact many applications in the project which have their own main-methods and separate classpaths. I know, it's a mess. I'm considering about migrating the project to NetBeans. In the long run it would be sensible to create many projects but for now it would be a real life-saver if I could do similar stuff in NetBeans than in Eclipse: create "launchers" which have their own classpaths. Is this possible? If it's easy to emulate this behaviour with "external" projects, hints about that are welcome as well.

  • How do I set the jax-ws client request timeout programatically on jboss?

    - by Jonas Andersson
    I am trying to set the request (and connection) timeout for a jax-ws-webservice-client generated with the jaxws-maven-plugin. When running my app under tomcat or jetty the timeout works, but when deployed under jboss it doesn't "take". private void setRequestAndConnectionTimeout(Object wsPort) { String REQUEST_TIMEOUT = BindingProviderProperties.REQUEST_TIMEOUT; // "com.sun.xml.ws.request.timeout"; ((BindingProvider) wsPort).getRequestContext().put(REQUEST_TIMEOUT, timeoutInMillisecs); ((BindingProvider) wsPort).getRequestContext().put(JAXWSProperties.CONNECT_TIMEOUT, timeoutInMillisecs); } What is the correct way to do this for JBoss?

  • Simple Xml list parsing problem

    - by Hubidubi
    I have this xml: <root> <fruitlist> <apple>4</apple> <apple>5</apple> <orange>2</orange> <orange>6</orange> </fruitlist> </root> I'm writing a parser class, although I can't figure out how to deal with multiple node types. I can easily parse a list that contains only one node type (eg. just apples, not oranges) @ElementList(name = "fruitlist") private List<Apple> exercises; with more than one node type it also wants so parse non Apple nodes which doesn't work. I also tried to make another list for oranges, but it doen't work, I can't use fruitlist name more than once. @ElementList(name = "fruitlist", entry = "orange") private List<Orange> exercises; The ideal would be two seperate list for both node types. Hubi EDIT: After more searching & fiddling this question is a duplicate: Inheritance with Simple XML Framework

  • Axis2 attachments are vanishing in the response

    - by Shamik
    I am using axis2 to come up with a basic web service which will get the file name as parameter and produces a response SOAP packet which will have the file attached along with the SOAP. Here is the way I am creating the service code (its simple and inspired by Axis2 sample code) public String getFile(String name) throws IOException { MessageContext msgCtx = MessageContext.getCurrentMessageContext(); File file = new File (name); System.out.println("File = " + name); System.out.println("File exists = " + file.exists()); FileDataSource fileDataSource = new FileDataSource(file); System.out.println("fileDataSource = " + fileDataSource); DataHandler dataHandler = new DataHandler(fileDataSource); System.out.println("DataHandler = " + dataHandler); String attachmentID = msgCtx.addAttachment(dataHandler); System.out.println("attachment ID = " + attachmentID); return attachmentID; } Now The client side code - MessageContext response = mepClient .getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE); SOAPBody body = response.getEnvelope().getBody(); OMElement element = body.getFirstElement().getFirstChildWithName( new QName("http://service.soapwithattachments.sample","return")); String attachementId = element.getText(); System.out.println("attachment id is " + attachementId); Attachments attachment = response.getAttachmentMap(); DataHandler dataHandler = attachment.getDataHandler(attachementId); Problem is that dataHandler is always null. Though I think at the server side, the file was read and attached along with the SOAP packet. Am I doing something wrong ? EDIT : I have put <parameter name="enableSwA" locked="false">true</parameter> in the axis2.xml file.

  • Best way for allowing subdomain session cookies using Tomcat

    - by Andrew Ingram
    By default tomcat will create a session cookie for the current domain. If you are on www.example.com, your cookie will be created for www.example.com (will only work on www.example.com). Whereas for example.com it will be created for .example.com (desired behaviour, will work on any subdomain of example.com as well as example.com itself). I've seen a few Tomcat valves which seem to intercept the creation of session cookies and create a replacement cookie with the correct .example.com domain, however none of them seem to work flawlessly and they all appear to leave the existing cookie and just create a new one. This means that two JSESSIONID cookies are being sent with each request. I was wondering if anybody has a definitive solution to this problem.
