  • How to create a datastore.Text object out of an array of dynamically created Strings?

    - by Adrogans
    I am creating a Google App Engine server for a project where I receive a large quantity of data via an HTTP POST request. The data is separated into lines, with 200 characters per line. The number of lines can go into the hundreds, so 10's of thousands of characters total. What I want to do is concatenate all of those lines into a single Text object, since Strings have a maximum length of 500 characters but the Text object can be as large as 1MB. Here is what I thought of so far: public void doPost(HttpServletRequest req, HttpServletResponse resp) { ... String[] audioSampleData = new String[numberOfLines]; for (int i = 0; i < numberOfLines; i++) { audioSampleData[i] = req.getReader().readLine(); } com.google.appengine.api.datastore.Text textAudioSampleData = new Text(audioSampleData[0] + audioSampleData[1] + ...); ... } But as you can see, I don't know how to do this without knowing the number of lines before-hand. Is there a way for me to iterate through the String indexes within the Text constructor? I can't seem to find anything on that. Of note is that the Text object can't be modified after being created, and it must have a String as parameter for the constructor. (Documentation here) Is there any way to this? I need all of the data in the String array in one Text object. Many Thanks!

  • File permissions question

    - by Camran
    If I need a php-page to have access to upload images and move images from a folder on the server, what permissions would I set on the folder then? I know we have "Owner", "Group", and "Others". But what does the server (or the php-code itself) count as? Owner? Also, would I need to set the php-page with the upload script with some specific permissions to be able to upload the files? Is it execute permissions? Thanks

  • When should I define an hash code function for my types?

    - by devoured elysium
    Is there any other reason for implementing an hash code function for my types other than allowing for good use of hash tables? Let's say I am designing some types that I intend to use internally. I know that types are "internal" to the system, and I also know I will never use those types in hash tables. In spite of this, I decide I will have to redefine the equals() method. Theory says I should also redefine the hash code method, but I can't see any reason why, in this case, I should do it. Can anyone point me out any other reason? This question can be rephrased to : in which situations should we implement a hash code method in our types. PS : I am not asking how to implement one. I am asking when.

  • Cannot submit form when disabling JSF page

    - by Steve
    Simple submit button. <h:commandButton actionListener="#{regBean.findReg}" action="#{regBean.navigate}" value="Search" /> The form tag is displayed like so: <h:form onsubmit="this.disabled=true;busyProcess();return true;"> This is so if the submit button is pressed, the page shows a "busy" icon until request is processed. The problem is, the request is never submitted and it never reaches the backend. However, if I instead take out the "disabled" call like so: <h:form onsubmit="busyProcess();return true;"> Everything works. Any ideas?

  • Renaming the argument name in JAX-WS

    - by user182944
    I created a web service using JAX-WS in RSA 7.5 and Websphere 7 using bottom-up approach. When I open the WSDL in SOAP UI, then the arguments section is appearing like this: <!--Optional--> <arg0> <empID>?</empId> </arg0> <!--Optional--> <arg1> <empName>?</empName> </arg1> <!--Optional--> <arg2> <empAddress>?</empAddress> </arg2> <!--Optional--> <arg3> <empCountry>?</empCountry> </arg3> The service method takes the above 4 elements as the parameters to return the employee details. 1) I want to rename this arg0, arg1, and so on with some valid names. 2) I want to remove the <!--optional--> present above the arg tags. (For removing the <!--optional--> from elements name, I used @XMLElement(required=true)). But I am not sure where exactly to use this annotation in this case :( Please help. Regards,

  • question on reverse array

    - by davit-datuashvili
    we know algorithm how reverse array of n integers for (int i=0;i<n/2;i++){ swap(a[i],a[n-1-i]): } is this method better according the speed of algorithm or not because swap using xor is more fast then in other method here is code public class swap { public static void main(String[]args){ int a[]=new int[]{2,4,5,7,8,11,13,12,14,24}; System.out.println(" array at the begining:"); for (int i=0;i<a.length;i++){ System.out.println(a[i]); } for (int j=0;j<a.length/2;j++){ a[j]^=a[a.length-1-j]; a[a.length-1-j]^=a[j]; a[j]^=a[a.length-1-j]; } System.out.println("reversed array:"); for (int j=0;j<a.length;j++){ System.out.println(a[j]); } } } Result: array at the begining: 2 4 5 7 8 11 13 12 14 24 reversed array: 24 14 12 13 11 8 7 5 4 2

  • Does beginTransaction in Hibernate allocate a new DB connection?

    - by illscience
    Hi folks - Just wondering if beginning a new transaction in Hibernate actually allocates a connection to the DB? I'm concerned b/c our server begins a new transaction for each request received, even if that request doesn't interact with the DB. We're seeing DB connections as a major bottleneck, so I'm wondering if I should take the time narrow the scope of my transactions. Searched everywhere and haven't been able to find a good answer. The very simple code is here: SessionFactory sessionFactory = (SessionFactory) Context.getContext().getBean("sessionFactory"); sessionFactory.getCurrentSession().beginTransaction(); sessionFactory.getCurrentSession().setFlushMode(FlushMode.AUTO); thanks very much! a

  • How to invoke a Servlet (doGet) in a web application on startup?

    - by Dan
    I need to invoke a Servlet on application startup since it contains some application initialization logic. I know I can set load-on-startup configuration, but this will only invoke Servlet’s init method. I need to invoke a doGet method and pass some Url parameters to it. Servlet doGet method expects ServletRequest and ServletResponse objects. Also, since this is clustered application, I need to know exactly what node I am accessing (since one option is just to open a socket and invoke a Servlet). What is the best option to perform this?

  • Call OnDraw in another method, then "refresh" that call in ANOTHER method.

    - by Aidan
    Hey guys, Hopefully this will actually make sense and sorry if its a stupid / obvious question. Basically I'm calling the onDraw method like so... requestWindowFeature(Window.FEATURE_NO_TITLE); Preview mPreview = new Preview(this); DrawOnTop mDraw = new DrawOnTop(this); setContentView(mPreview); addContentView(mDraw, new LayoutParams (LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); You see I'm drawing it on top of a Camera view and the information being drawn is subject to change. I have a listener setup which will update the variables being drawn at the appropriate time but I now want to "refresh" this draw in that listener. How would I do such a thing?

    - by bhavna raghuvanshi
    here is the whole program: public class ListMerge { public static void main( String[] args) { Scanner input = new Scanner(System.in); System.out.println ("Input length of arraylist 1:"); int n = input.nextInt(); ArrayList x = new ArrayList(); ArrayList y = new ArrayList(); for (int i = 0; i < n; i++) { System.out.println ("Input x[ " + i +"] :" ); x.add(new Integer(i)); } System.out.println ("Input length of arraylist 2:"); int m = input.nextInt(); for (int i = 0; i < m; i++) { System.out.println ("Input y[ " + i +"] :" ); y.add(new Integer(i)); } } list int merge(ArrayList x, ArrayList y) { List all = new ArrayList(); all.addAll(x); all.addAll(y); System.out.println(all); return all; } } also tell me how do i call the function merge?

  • Netbeans IDE tutorials

    - by James P.
    I mostly use Eclipse but have mentionned Netbeans on my cv. Are there any good concise and up-to-date tutorials apart from the official ones that could bring me up to speed on how to use the IDE efficiently (shortcuts, debugging, views ...)? This excludes programming tutorials as I don't really need them unless there's a special manipulation involved.

  • Solution to compiler warning for generic varargs

    - by TJR
    A puzzle from this blog. Similar to SO1445233. Given the following source listing, explain why the compiler is producing a warning at invocation to the list method and give a solution for removing the warning without resorting to @SuppressWarnings annotation. public class JavaLanguagePuzzle3 { public static void main(String[] args) { list("1", 2, new BigDecimal("3.5")); } private static <T> List<T> list(T... items) { return Arrays.asList(items); } } Warning: Type safety: A generic array of Object&Serializable&Comparable<?> is created for a varargs parameter

  • Adding interfaces that won't be actually used

    - by devoured elysium
    I currently have two interfaces(that I'll name here IA and IB): interface IA { int Width; int Height; ... } interface IB { int Width; int Height; ... } that share the same two properties: they both have a Width and a Height property. I was thinking if there is any point in defining an IMatrix interface containing a Width and Height properties: interface IMatrix { int Width; int Height; } The thing is that although they share both the same properties, I won't make use of polymorphism with IMatrix in any of my coding: i.e., there won't by any situation where I'll want to use an IMatrix, I'll just want to use IA and IB. Adding an IMatrix seems more like over-engineering than other thing, but I'd like to ask you guys what your opinion is on the matter. Thanks

  • HashMap.containsValue - What's the point?

    - by Frederik
    I've got a HashMap and I need to fetch an item by its integer value. I notice there's a containsValue() function, but it would appear I still have to iterate through the map to find the correct index anyway. My question is; why use containsValue() if I'm required to traverse it afterwards? Also, am I missing the point completely? ;-)

  • hibernate.properties classpath conflict

    - by Adam B
    I have a jar on the classpath which contains a hibernate.properties. This causes problems when my app starts because hibernate tries to use the settings from this file. Is there a way to explicitly specify the file that hibernate should look for, or tell it to ignore the properties file in the dependency jar?
