  • Non-empty list with null elements returned from Hibernate query

    - by John
    Hi, I'm new to hibernate so not sure if this is an expected behaviour, anyway: Session session = (Session)entityManager.getDelegate(); Criteria criteria = session.createCriteria(myRequest.class); criteria.add(Restrictions.eq("username", username)); criteria.setProjection(Projections.max("accesscount")); List<myRequest> results = criteria.list(); The returned results is a non-empty list with a single null element. I can't think of any reason why it should behave this way, any idea if this is the expected behaviour or have I done something wrong? System is on hibernate/Syabse. Thanks.

  • Detect months with 31 days

    - by daddycardona
    Is there an analogous form of the following code: if(month == 4,6,9,11) { do something; } Or must it be: if(month == 4 || month == 6 etc...) { do something; } I am trying to write an if statement that checks if this month has more than 31 days.

  • Httpclient not returning entire response

    - by whakojacko
    Using HttpClient 4.0, Im having an issue where the response I get from the ResponseHandler is only about half of what the actual page content should be (~61k bytes in the string vs ~125k in the page returned to a browser). I cant seem to find any place where there might be some sort of limit that would limit this. Any ideas?

  • URL getRequestParameterMap not working

    - by DD
    I'm using IceFaces 1.8.2 and trying to get a parameter from the URL using: ((HttpServletRequest) FacesContext.getCurrentInstance() .getExternalContext().getRequest()).getParameter(name); This works fine on the inital request. However, when I do a partialSubmit on a component, it stops working. I'm assuming that its to do with how requests are processed when partial submits are done. Is there a workaround? At the moment, I'm having to ((HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext() .getRequest()).getQueryString(); and manually pass the query string. Thanks.

  • JQuery Tabs - HTML not displayed in any other tab except default tab

    - by user346347
    I'm pretty new to jquery, but I have a tab structure working and make a $.getJSON call to retrieve the JSON results from the backend. Now, I have 3 tabs: Tab1, Tab2 and Tab3. All the three tabs have the same divs but different content. The content shows up just fine in the first tab which is shown by default, but on clicking the 2nd tab, I make the same $.getJSON call and retrieve the JSON just fine, the same HTML is being constructed on the fly and set in the DIV within the tab but it is not being displayed... Any pointers??

  • starting index from 1 not from 0

    - by M.H
    My question is simple (I think it is silly too) ,how can I start the index in an ArrayList from 1 instead of 0 ? is this possible directly (I mean is there a code for this ) ?. Actually a friend asked me this question today, first I thought that it is a silly question but after a while I thought if there is a direct way to do that and decided to ask it to you (maybe you have some brilliant ideas :) )

  • 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

  • How do I "valueOf" an enum given a class name?

    - by stevemac
    Lets say I have a simple Enum called Animal defined as: public enum Animal { CAT, DOG } and I have a method like: private static Object valueOf(String value, Class<?> classType) { if (classType == String.class) { return value; } if (classType == Integer.class) { return Integer.parseInt(value); } if (classType == Long.class) { return Long.parseLong(value); } if (classType == Boolean.class) { return Boolean.parseBoolean(value); } // Enum resolution here } What can I put inside this method to return an instance of my enum where the value is of the classType? I have looked at trying: if (classType == Enum.class) { return Enum.valueOf((Class<Enum>)classType, value); } But that doesn't work.

  • which delimeter to use while spliting String

    - by London
    I need to split this line string in each line, I need to get the third word(film name) but as you see the delimeter is one big blank character in some cases its small like before the numbers at the end or its big as in front of numbers at front. I tried using string split with(" ") regex, and also \t but get the out of the bounds error. 400115305 Lionel_Atwill The_Song_of_Songs_(1933_film) 7587 400115309 Brian_Aherne A_Night_to_Remember_(1943_film) 7952 Did anyone have the same problem?

  • Union of two or more (hash)maps

    - by javierfp
    I have two Maps that contain the same type of Objects: Map<String, TaskJSO> a = new HashMap<String, TaskJSO>(); Map<String, TaskJSO> b = new HashMap<String, TaskJSO>(); public class TaskJSO { String id; } The map keys are the "id" properties. a.put(taskJSO.getId(), taskJSO); I want to obtain a list with: all values in "Map b" + all values in "Map a" that are not in "Map b". What is the fastest way of doing this operation? Thanks EDIT: The comparaison is done by id. So, two TaskJSOs are considered as equal if they have the same id (equals method is overrided). My intention is to know which is the fastest way of doing this operation from a performance point of view. For instance, is there any difference if I do the "comparaison" in a map (as suggested by Peter): Map<String, TaskJSO> ab = new HashMap<String, TaskJSO>(a); ab.putAll(b); ab.values() or if instead I use a set (as suggested by Nishant): Set s = new Hashset(); s.addAll(a.values()); s.addAll(b.values());

  • MediaType of REST

    - by user357243
    Hi, I am beginner in REST web services. I wrote a program of REST to display the HTML or XML. The @Path annotation's value is @Path("{typeDocument}"). There are two methods for GET : @GET @Produces(MediaType.TEXT_XML) public String getXml(@PathParam("typeDocument") String typeDocument) to display XML file, and @GET @Produces(MediaType.TEXT_HTML) public String getHtml(@PathParam("typeDocument") String typeDocument) to display HTML. The browser Firefox always excutes getHtml() when URL is either http://localhost:8080/sources/html or localhost:8080/sources/xml But IE always excutes getXml(). How to excute the correct method, as defined by URL, in different browser ? Thanks a lot.
