  • Using IvyDE with different workspaces on different branches

    - by James Woods
    I am having problems using IvyDE when I have different workspaces for different branches. I have "Resolve dependencies in workspace" switched on. But everytime I change to a different workspace I have to remember to manually clean the caches out. This is because IvyDE always uses the default cache for resolving dependencies within a workspace, so when switching between workspaces the cache can be polluted by different versions. It would seem that it is impossible to work with two different workspaces at the same time. I cannot find a way to configure the location that IvyDE uses to cache the project dependencies. It does not appear to use the caches defined in the ivysettings.xml

  • Check if BigDecimal is integer value

    - by Adamski
    Can anyone recommend an efficient way of determining whether a BigDecimal is an integer value in the mathematical sense? At present I have the following code: private boolean isIntegerValue(BigDecimal bd) { boolean ret; try { bd.toBigIntegerExact(); ret = true; } catch (ArithmeticException ex) { ret = false; } return ret; } ... but would like to avoid the object creation overhead if necessary. Previously I was using bd.longValueExact() which would avoid creating an object if the BigDecimal was using its compact representation internally, but obviously would fail if the value was too big to fit into a long. Any help appreciated.

  • Intersecting boundaries with lucene

    - by Silvio Donnini
    I'm using Lucene, and I'm trying to find a way to index and retrieve documents that have a ranged property. For example I have: Document 1: Price:[30 TO 50] Document 2: Price:[45 TO 60] Document 3: Price:[60 TO 70] And I would like to search for all the documents whose ranges intersect a specific interval, in the above example, if I search for Price in [55 TO 65] I should get Document 2 and Document 3 as results. I don't think NumericRangeQueries alone would do the trick, I need to work on the index with something similar to R-trees, but are they implemented in Lucene? Also, I suppose that what I need should be a subclass of MultiTermQuery, because the query Price in [55 TO 65] has two boundaries, but I don't see anything suitable among MultiTermQuery's subclasses. Any help is appreciated, thanks, Silvio P.S. I'm using Lucene 2.9.0, but I can update to the latest release if needed.

  • Netbeans Editor Library?

    - by Jeremybub
    Netbeans seems to say in several places that it supports a library to just host the "Netbeans editor" widget in some other program. It has some weird documentation that seems to say a lot, but doesn't really say much about how to use it: http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-editor-lib2/architecture-summary.html I can't seem to find any download for the "Netbeans editor library" (1 or 2), and the documentation they provide says to download the entire mercurial repository, which doesn't really help me, since it doesn't tell me what is part of this "library" and what is not. If someone could point me to a download for this library, or some minimal documentation about how to use it, that would be great. I've already seen the blog post here, but it doesn't really help with getting the library, and it seems to be talking about classes which I can't find in the Netbeans sources I downloaded (Maybe a different version?)

  • Setting refresh-policies in Ehcache

    - by Alex Ciminian
    Is there any to specify a data refresh policy in Ehcache? I am currently migrating an application from OSCache to Ehcache and I can't seem to find any way to specify when an element needs refreshing, besides setting timeToIdle and timeToLive. What I want is: on accessing an element from the cache, check with it's associated resource to see if it was updated later than the lastUpdateTime of the cache element. If yes, refresh the cache; else serve the content from the cache. In OSCache this was done by catching NeedsRefreshExceptions and setting custom refresh policies for the elements. I've been digging around in the docs for a while now, but I wasn't able to find any methods or examples of how I could accomplish this in Ehcache. Any help would be appreciated :). Alex

  • GridView: How can I get rid of extra space from my GirdView object?

    - by Lajos Arpad
    Hello, I'm writing an application for Android phones for Human vs. Human chess play over the internet. I was looking at some tutorials, to learn how to develop Android applications and found a very nice example of making galleries (it was a GridView usage example for making a gallery about dogs) and the idea came to draw the chess table using a GridView, because the example project also handled the point & click event and I intended to use the same event in the same way, but for a different purpose. The game works well (currently it's a hotseat version), however, I'm really frustrated by the fact that whenever I rotate the screen of the phone, my GridView gets hysterical and puts some empty space in my chess table between the columns. I realized that the cause of this is that the GridView's width is the same as its parent's and the GridView tries to fill its parent in with, but there should (and probably is) be a simple solution to get rid of this problem. However, after a full day of researching, I haven't found any clue to help me to make a perfect drawing about my chess table without a negative side effect in functionality. The chess table looks fine if the phone is in Portrait mode, but in Landscape mode it's far from nice. This is how I can decide whether we are in Portrait or Landscape mode: ((((MainActivity)mContext).getWindow().getWindowManager().getDefaultDisplay().getWidth()) < ((MainActivity)mContext).getWindow().getWindowManager().getDefaultDisplay().getHeight()) In the main.xml file the GridView is defined in the following way: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numColumns="8" android:verticalSpacing="0dp" android:horizontalSpacing="0dp" android:stretchMode="columnWidth" android:gravity="center" > </GridView> ... </LinearLayout> I appreciate any help with the problem and thank you for reading this.

  • Programatically setting castor properites in version 1.3

    - by Dinuk
    Hello, I am trying to programmatically set the org.exolab.castor.indent property when marshalling some objects - however, contrary to the documentation published, the class org.exolab.castor.util.LocalConfiguration does not seem to be shipped with the 1.3 release. Currently, I have specified the castor.properties file on the classpath, which is picking up the properties I want to set, but I would rather reduce this deployment overhead, as my indentation requirement is not likely to change. Any advice would be greatly appreciated.

  • How do Tomcat examples work?

    - by Bialecki
    Alright, this is a very simple question. I just installed Tomcat 6 on my Mac to play around with it, and every tutorial I look at says the first thing to do to create a new web application is to add a line to the server.xml file with defines a new Context. Fair enough. However, my question is, I don't see a line in there for the example web applications, so how do those work?

  • Dynamic Typed Table/Model in J2EE?

    - by Viele
    Hi, Usually with J2EE when we create Model, we define the fields and types of fields through XML or annotation before compilation time. Is there a way to change those in runtime? or better, is it possible to create a new Model based on the user's input during the runtime? such that the number of columns and types of fields are dynamic (determined at runtime)? Help is much appreciated. Thank you.

  • thoughs on using Alpha Five v10 with Codeless AJAX for building an AJAX database app in a short amou

    - by william Hunter
    I need to build an AJAX application against our MS SQL Server database for my company. the app has to have user permissions and reporting and is pretty complex. I am really under the gun in terms of time. The company that I work for needs the app for an important project launch. A colleague/friend of mine in a different company recommended that I look at a product from Alpha Software called Alpha Five v10 with Codeless AJAX. He has told me that he has used it extensively and that it saves him a "serious boat load of time" and he says that he has not run into limitations because you can also write your own JavaScript or you wire in JQERY. Before I commit to Alpha Five v10, I would like to get any other opinions? Thanks. Norman Stern. Chicago

  • Help regarding composite pattern with hibernate

    - by molleman
    Hello, So i am stuck, i am creating a gwt web application, i will be using a tree(gwt Tree and TreeItems) structure to show a list of folders(class Folder) and files(class FileLocation), the folder and filelocation class will all implement a Hierarchy interface basing the classes on the composite pattern. but i am using hibernate to store my data , and i am using annotations for the mapping of the data to the database. my trouble is i do not know how to annotate my interface. have any of you guys used the composite pattern while persisting the data with hibernate public interface Hierarchy(){ // a few abstract methods that will be implemented by the sub classes } @Entity @Table() public class Folder extends Hierarchy implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "folder_id", updatable = false, nullable = false) private int id; @OneToMany(cascade = CascadeType.ALL,fetch = FetchType.EAGER) @JoinTable(name = "FOLDER_FILELOCATION", joinColumns = { @JoinColumn(name = "folder_id") }, inverseJoinColumns = { @JoinColumn(name = "file_information_id") }) private List<Hierarchy> children = new ArrayList<Hierarchy>() ; @Column(name = "folder_name") private String folderName; @Column(name = "tree_item") private TreeItem item; @Column (name = "parent") private Hierarchy parent; @Entity @Table(name = "FILE_INFORMATION_TABLE") public class FileInformation extends Hierarchy implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "file_information_id", updatable = false, nullable = false) private int fiId; @Column (name = "location") private String location; @Column(name = "tree_item") private TreeItem item; @Column (name = "parent") private Hierarchy parent;

  • t:commandSortHeader not being styled

  • JPA @ManyToMany on only one side?

    - by Ethan Leroy
    I am trying to refresh the @ManyToMany relation but it gets cleared instead... My Project class looks like this: @Entity public class Project { ... @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER) @JoinTable(name = "PROJECT_USER", joinColumns = @JoinColumn(name = "PROJECT_ID", referencedColumnName = "ID"), inverseJoinColumns = @JoinColumn(name = "USER_ID", referencedColumnName = "ID")) private Collection<User> users; ... } But I don't have - and I don't want - the collection of Projects in the User entity. When I look at the generated database tables, they look good. They contain all columns and constraints (primary/foreign keys). But when I persist a Project that has a list of Users (and the users are still in the database), the mapping table doesn't get updated gets updated but when I refresh the project afterwards, the list of Users is cleared. For better understanding: Project project = ...; // new project with users that are available in the db System.out.println(project getUsers().size()); // prints 5 em.persist(project); System.out.println(project getUsers().size()); // prints 5 em.refresh(project); System.out.println(project getUsers().size()); // prints 0 So, how can I refresh the relation between User and Project?

  • Setting up ehcache replication - what multicast settings do I need?

    - by Darren Greaves
    I am trying to set up ehcache replication as documented here: http://ehcache.sourceforge.net/EhcacheUserGuide.html#id.s22.2 This is on a Windows machine but will ultimately run on Solaris in production. The instructions say to set up a provider as follows: <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory" properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1, multicastGroupPort=4446, timeToLive=32"/> And a listener like this: <cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" properties="hostName=localhost, port=40001, socketTimeoutMillis=2000"/> My questions are: Are the multicast IP address and port arbitrary (I know the address has to live within a specific range but do they have to be specific numbers)? Do they need to be set up in some way by our system administrator (I am on an office network)? I want to test it locally so am running two separate tomcat instances with the above config. What do I need to change in each one? I know both the listeners can't listen on the same port - but what about the provider? Also, are the listener ports arbitrary too? I've tried setting it up as above but in my testing the caches don't appear to be replicated - the value added in one tomcat's cache is not present in the other cache. Is there anything I can do to debug this situation (other than packet sniffing)? Thanks in advance for any help, been tearing my hair out over this one!

  • Hot deploy not longer working on JBoss

    - by Bernhard V
    Hi! I've got a pretty annoying problem with my JBoss AS 4.2.3 GA. Until recently everything was running fine, but now the hot deploy feature is now longer working. And -- as always -- I don't know what I did to cause this behaviour. My projects are built with Maven. I've cleaned every target directory, installed the projects and then deployed them to the server. So the sources in Eclipse and the deployed projects on the server should be identical. Inside a method I've added a simple System.out.println("test"); statement and -- BANG! -- I get the following error: Do you know a way out of my trouble?
