  • about Select algorithm

    - by matin1234
    Hi I have read about the select algorithm and I have a question maybe it looks silly!!! but why we consider the array as groups of 5 elements ?? can we consider it with 7 or 3 elements??thanks

  • Merging two templates in iText

    - by Shaggy Frog
    Let's say I have two PDF templates created with Adobe Acrobat, which are both single-page, 8.5x11 documents. The first template (A.pdf) has content for the top half of the page. The second template (B.pdf) has content for the bottom half of the page. (It just so happens the content in both templates does not "overlap" each other.) I would like to use iText to take these two templates and create a single, "merged" template from it (C.pdf) that is only a single page (with A.pdf's content on the top half and B.pdf's content on the bottom half). (I do not want to "merge" these two files into a 2-page document. I need the final product to be a single page.) I will be running iText in a servlet environment (Tomcat 6) but I don't think that makes a difference to the answer. Is this possible?

  • ant scp task through a proxy

    - by xask
    I am trying to make an ant build file to remote copy a war file. Ant scp task uses a jsch library for remote copying. How do I make it work through a proxy, the jsch library clearly supports it. does not work for jsch. Jsch does not read environment variables like http_proxy is there another solution ?

  • Multiplication of 2 positive numbers giving a negative result

    - by krandiash
    My program is an implementation of a bloom filter. However, when I'm storing my hash function results in the bit array, the function (of the form f(i) = (a*i + b) % m where a,b,i,m are all positive integers) is giving me a negative result. The problem seems to be in the calculation of a*i which is coming out to be negative. Ignore the print statements in the code; those were for debugging. Basically, the value of temp in this block of code is coming out to be negative and so I'm getting an ArrayOutOfBoundsException. m is the bit array length, z is the number of hash functions being used, S is the set of values which are members of this bloom filter and H stores the values of a and b for the hash functions f1, f2, ..., fz. public static int[] makeBitArray(int m, int z, ArrayList<Integer> S, int[] H) { int[] C = new int[m]; for (int i = 0; i < z; i++) { for (int q = 0; q < S.size() ; q++) { System.out.println(H[2*i]); int temp = S.get(q)*(H[2*i]); System.out.println(temp); System.out.println(S.get(q)); System.out.println(H[2*i + 1]); System.out.println(m); int t = ((H[2*i]*S.get(q)) + H[2*i + 1])%m; System.out.println(t); C[t] = 1; } } return C; } Any help is appreciated.

  • custom tag 'cannot be resolved to a type'

    - by lotus99t
    I have a custom tag, packaged into a library jar that is included in my web apps war file. I get the following error: An error occurred at line: 66 in the jsp file: /WEB-INF/jsp/portlet/portfolio/operations/operationsInfo.jsp org.apache.jsp.tag.meta.form.WidgetFactory_tag cannot be resolved to a type 63: <c:forEach var="fldCfg" items="${config.page.fields}" > 64: <tr> 65: <td><form:Label fld="${fldCfg}"/></td> 66: <td><form:WidgetFactory fld="${fldCfg}" decodesMap="${decodesMap}" command="${operationsInfoBean}" dateFormat="${preferredDateFormat}"/></td> 67: </tr> 68: </c:forEach> 69: </table> But it doesn't seem to complain about Label which is in the same taglib. I've confirmed that the jar is in the war and that the tag file is in the jar and the that the TLD (in META-INF) expressly defines 'WidgetFactory' Why am I getting this error?

  • Quartz Cron Trigger with Spring - triggering new cron before last ended

    - by Trick
    Simple question, I think. I have org.springframework.scheduling.quartz.CronTriggerBean triggering one job once a day. Because this method can last a long time (over 24 hours), will the next day at the same time a new job be executed if the last one is not ended yet? If yes - is it possible to turn off executing new jobs until the last one is finished? My method is trans-coding videos and some days there a lot of videos and could last long.

  • JVM missing Rhino

    - by Andrei
    I have a project that uses the ScriptEngine to process some javascript, and worked well on my machine, but when i send the projects's jar to the server, i had discovered that the server's JVM doesn't have Rhino built-in, returning null when the code calls a new ScriptEngineManager().getEngineByName("javascript"); I went to the rhino's download page, get the most recent version, and extracted the js.jar from it, added the jar on the project, but still have the same problem.

  • How to stream XML data using XOM?

    - by Jonik
    Say I want to output a huge set of search results, as XML, into a PrintWriter or an OutputStream, using XOM. The resulting XML would look like this: <?xml version="1.0" encoding="UTF-8"?> <resultset> <result> [child elements and data] </result> ... ... [1000s of result elements more] </resultset> Because the resulting XML document could be big (tens or hundreds of megabytes, perhaps), I want to output it in a streaming fashion (instead of creating the whole Document in memory and then writing that). The granularity of outputting one <result> at a time is fine, so I want to generate one <result> after another, and write it into the stream. Assume there's already a method that helps with iterating the results and generating Element objects: public nu.xom.Element getNextResult(); So I'd simply like to do something like this pseudocode (automatic flushing enabled, so don't worry about that) : open stream/writer write declaration write start tag for <resultset> while more results: write next <result> element write end tag for <resultset> close stream/writer I've been looking at Serializer, but the necessary methods, writeStartTag(Element), writeEndTag(Element), write(DocType) are protected, not public! Is there no other way than to subclass Serializer to be able to use those methods, or to manually write the start and end tags directly into the stream as Strings, bypassing XOM altogether? (The latter wouldn't be too bad in this simple example, but in the general case it would get quite ugly.) Am I missing something or is XOM just not made for this? With dom4j I could do this easily using XMLWriter - it has constructors that take a Writer or OutputStream, and methods writeOpen(Element), writeClose(Element), writeDocType(DocumentType) etc. Compare to XOM's Serializer where the only public write method is the one that takes a whole Document. Please refrain from answering if you're not familiar with XOM! I specifically want to know if and how you can do this kind of streaming with that library. (This is related to my question about the best dom4j replacement where XOM is a strong contender.)

  • Add a new element to a SortedSet

    - by arjacsoh
    Can someone explain me why this code compiles and runs fine, despite the fact that SortedSet is an interface and not a concrete class: public static void main(String[] args) { Integer[] nums = {4, 7, 8, 14, 45, 33}; List<Integer> numList = Arrays.asList(nums); TreeSet<Integer> numSet = new TreeSet<Integer>(); numSet.addAll(numList); SortedSet<Integer> sSet = numSet.subSet(5, 20); sSet.add(17); System.out.println(sSet); } It prints normally the result: [7, 8, 14, 17] Furthermore, my wonder is heightened by the fact that the SortedSet cannot be instansiated (expectedly). This line does not compile: SortedSet<Integer> sSet = new SortedSet<Integer>(); However, if I try the code: public static void main(String[] args) { Integer[] nums = {4, 7, 8, 14, 45, 33}; List<Integer> numList = Arrays.asList(nums); numList.add(56); System.out.println(numList); } it throws an UnsupportedOperationException. I reckon, this comes from the fact that List is an interface and cannot be handled as a concrete class. What is true about SortedSet?

  • Blob object not working properly even though the class is seralized

    - by GustlyWind
    I have class which is seralized and does convert a very large amount of data object to blob to save it to database.In the same class there is decode method to convert blob to the actual object.Following is the code for encode and decode of the object. private byte[] encode(ScheduledReport schedSTDReport) { byte[] bytes = null; try { ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(bos); oos.writeObject(schedSTDReport); oos.flush(); oos.close(); bos.close(); //byte [] data = bos.toByteArray(); //ByteArrayOutputStream baos = new ByteArrayOutputStream(); //GZIPOutputStream out = new GZIPOutputStream(baos); //XMLEncoder encoder = new XMLEncoder(out); //encoder.writeObject(schedSTDReport); //encoder.close(); bytes = bos.toByteArray(); //GZIPOutputStream out = new GZIPOutputStream(bos); //out.write(bytes); //bytes = bos.toByteArray(); } catch (Exception e) { _log.error("Exception caught while encoding/zipping Scheduled STDReport", e); } decode(bytes); return bytes; } /* * Decode the report definition blob back to the * ScheduledReport object. */ private ScheduledReport decode(byte[] bytes) { ByteArrayInputStream bais = new ByteArrayInputStream(bytes); ScheduledReport sSTDR = null; try { ObjectInputStream ois = new ObjectInputStream(bais); //GZIPInputStream in = new GZIPInputStream(bais); //XMLDecoder decoder = new XMLDecoder(in); sSTDR = (ScheduledReport)ois.readObject();//decoder.readObject(); //decoder.close(); } catch (Exception e) { _log.error("IOException caught while decoding/unzipping Scheduled STDReport", e); } return sSTDR; } The problem here is whenver I change something else in this class means any other method,a new class version is created and so the new version the class is unable to decode the originally encoded blob object. The object which I am passing for encode is also seralized object but this problem exists. Any ideas thanks

  • Invalid method declaration, return type required

    - by Brett Steen
    I am getting an error at public Rectangle(double width, double height){ saying that it's an invalid method declaration, return type required. I'm not sure how to fix it. These are also my instructions for my assignment: Write a super class encapsulating a rectangle. A rectangle has two attributes representing the width and the height of the rectangle. It has methods returning the perimeter and the area of the rectangle. This class has a subclass, encapsulating a parallelepiped, or box. A parallelepiped has a rectangle as its base, and another attribute, its length. It has two methods that calculate and return its area and volume. `public class Rectangle1 { private double width; private double height; public Rectangle1(){ } public Rectangle(double width, double height){ this.width = width; this.height = height; } public double getWidth(){ return width; } public void setWidth(double width) { this.width = width; } public double getHeight(){ return height; } public void setHeight(double height){ this.height = height; } public double getArea(){ return width * height; } public double getPerimeter(){ return 2 * (width + height); } } public class TestRectangle { public static void main(String[] args) { Rectangle1 rectangle = new Rectangle1(2,4); System.out.println("\nA rectangle " + rectangle.toString()); System.out.println("The area is " + rectangle.getArea()); System.out.println("The perimeter is " + rectangle.getPerimeter()); } }`

  • How to perform ant path mapping in war task?

    - by eljenso
    I have several JAR file pattern sets, like <patternset id="common.jars"> <include name="external/castor-1.1.jar" /> <include name="external/commons-logging-1.2.6.jar" /> <include name="external/itext-2.0.4.jar" /> ... </patternset> I also have a war task containing a lib element: ... Like this however, I end up with a WEB-INF/lib containing the subdirectories from my patterns: WEB-INF/lib/external/castor-1.1.jar WEB-INF/lib/external/... Is there any way to flatten this, so the JAR files appear top-level under WEB-INF/lib, regardless of the directories specified in the patterns? I looked at mapper but it seems you cannot use them inside lib.

  • Android spinner inside a custom control - OnItemSelectedListener does not trigger

    - by Idan
    I am writing a custom control that extends LinearLayout. Inside that control I am using a spinner to let the user select an item from a list. The problem I have is that the OnItemSelectedListener event does not fire. When moving the same code to an Activity/Fragment all is working just fine. I have followed some answers that was given to others asking about the same issue, and nothing helped. still the event does not fire. This is my code after I followed the answers that suggested to put the spinner inside my layout XML instead of by code. I am getting the same result when I try to just "new Spinner(ctx)"... layout XML: <Spinner android:id="@+id/accSpinner" android:layout_width="0dip" android:layout_height="0dip" /> Initialization function of the control (called on the control constructor): private void init() { LayoutInflater layoutInflater = LayoutInflater.from(mContext); mAccountBoxView = layoutInflater.inflate(R.layout.control_accountselector, null); mTxtAccount = (TextView)mAccountBoxView.findViewById(R.id.txtAccount); mSpinner = (Spinner)mAccountBoxView.findViewById(R.id.accSpinner); mAccountBoxView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { mSpinner.performClick(); } }); setSpinner(); addView(mAccountBoxView); } private void setSpinner() { ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_spinner_item, mItems); dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); mSpinner.setAdapter(dataAdapter); mSpinner.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { String selectedItem = mItems.get(position); handleSelectedItem(selectedItem); } @Override public void onNothingSelected(AdapterView<?> parent) { } }); } The spinner raises just fine when i touch my control and the list of items is there as it should. When I click an item the spinner closes but I am never getting to onItemSelected nor onNothingSelected.. Any ideas?

  • How to find the first declaring method for a reference method

    - by Oliver Gierke
    Suppose you have a generic interface and an implementation: public interface MyInterface<T> { void foo(T param); } public class MyImplementation<T> implements MyInterface<T> { void foo(T param) { } } These two types are frework types. In the next step I want allow users to extend that interface as well as redeclare foo(T param) to maybe equip it with further annotations. public interface MyExtendedInterface extends MyInterface<Bar> { @Override void foo(Bar param); // Further declared methods } I create an AOP proxy for the extended interface and intercept especially the calls to furtherly declared methods. As foo(…) is no redeclared in MyExtendedInterface I cannot execute it by simply invoking MethodInvocation.proceed() as the instance of MyImplementation only implements MyInterface.foo(…) and not MyExtendedInterface.foo(…). So is there a way to get access to the method that declared a method initially? Regarding this example is there a way to find out that foo(Bar param) was declared in MyInterface originally and get access to the accoriding Method instance? I already tried to scan base class methods to match by name and parameter types but that doesn't work out as generics pop in and MyImplementation.getMethod("foo", Bar.class) obviously throws a NoSuchMethodException. I already know that MyExtendedInterface types MyInterface to Bar. So If I could create some kind of "typed view" on MyImplementation my math algorithm could work out actually.

  • B-Tree Revision

    - by stan
    Hi, If we are looking for line intersections (horizontal and vertical lines only) and we have n lines with half of them vertical and no intersections then Sorting the list of line end points on y value will take N log N using mergesort Each insert delete and search of our data structue (assuming its a b-tree) will be < log n so the total search time will be N log N What am i missing here, if the time to sort using mergesort takes a time of N log N and insert and delete takes a time of < log n are we dropping the constant factor to give an overal time of N log N. If not then how comes < log n goes missing in total ONotation run time? Thanks
