  • Failed to allocate memory: 8

    - by Denis Hoss
    From today, when I tried to run an app in NetBeans on a 2.3.3 Android platform, it shows me that: Failed to allocate memory: 8 This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. and the Emulator doesn't want to start. This is for the first time when I see it, and google has no asnwers for this, I tried even with 2 versions of NetBeans 6.9.1 and 7.0.1, still the same error.

  • What is the easiest way to generate a Valid x:Name?

    - by just in case
    I am generating some Xaml based on some other source of input. In some cases I am generating x:Name values but they have invalid characters. I found this article on MSDN: XamlName Grammar Which describes the grammar of a x:Name tag but doesn't tell me how to actually apply this. Clearly there is some code to validate this name at runtime but what is the easiest way to actually fix up a string with invalid characters?

  • Hibernate Persistence problems with Bean Mapping (Dozer)

    - by BuffaloBuffalo
    I am using Hibernate 3, and having a particular issue when persisting a new Entity which has an association with an existing detached entity. Easiest way to explain this is via code samples. I have two entities, FooEntity and BarEntity, of which a BarEntity can be associated with many FooEntity: @Entity public class FooEntity implements Foo{ @Id private Long id; @ManyToOne(targetEntity = BarEntity.class) @JoinColumn(name = "bar_id", referencedColumnName = "id") @Cascade(value={CascadeType.ALL}) private Bar bar; } @Entity public class BarEntity implements Bar{ @Id private Long id; @OneToMany(mappedBy = "bar", targetEntity = FooEntity.class) private Set<Foo> foos; } Foo and Bar are interfaces that loosely define getters for the various fields. There are corresponding FooImpl and BarImpl classes that are essentially just the entity objects without the annotations. What I am trying to do is construct a new instance of FooImpl, and persist it after setting a number of fields. The new Foo instance will have its 'bar' member set to an existing Bar (runtime being a BarEntity) from the database (retrieved via session.get(..)). After the FooImpl has all of its properties set, Apache Dozer is used to map between the 'domain' object FooImpl and the Entity FooEntity. What Dozer is doing in the background is instantiating a new FooEntity and setting all of the matching fields. BarEntity is cloned as well via instantiation and set the FooEntity's 'bar' member. After this occurs, passing the new FooEntity object to persist. This throws the exception: org.hibernate.PersistentObjectException: detached entity passed to persist: com.company.entity.BarEntity Below is in code the steps that are occurring FooImpl foo = new FooImpl(); //returns at runtime a persistent BarEntity through session.get() Bar bar = BarService.getBar(1L); foo.setBar(bar); ... //This constructs a new instance of FooEntity, with a member 'bar' which itself is a new instance that is detached) FooEntity entityToPersist = dozerMapper.map(foo, FooEntity.class); ... session.persist(entityToPersist); I have been able to resolve this issue by either removing or changing the @Cascade annotation, but that limits future use for say adding a new Foo with a new Bar attached to it already. Is there some solution here I am missing? I would be surprised if this issue hasn't been solved somewhere before, either by altering how Dozer Maps the children of Foo or how Hibernate reacts to a detached Child Entity.

  • C++ Vector vs Array (Time)

    - by vsha041
    I have got here two programs with me, both are doing exactly the same task. They are just setting an boolean array / vector to the value true. The program using vector takes 27 seconds to run whereas the program involving array with 5 times greater size takes less than 1 s. I would like to know the exact reason as to why there is such a major difference ? Are vectors really that inefficient ? Program using vectors #include <iostream> #include <vector> #include <ctime> using namespace std; int main(){ const int size = 2000; time_t start, end; time(&start); vector<bool> v(size); for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - 27 seconds Program using Array #include <iostream> #include <ctime> using namespace std; int main(){ const int size = 10000; // 5 times more size time_t start, end; time(&start); bool v[size]; for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - < 1 seconds Platform - Visual Studio 2008 OS - Windows Vista 32 bit SP 1 Processor Intel(R) Pentium(R) Dual CPU T2370 @ 1.73GHz Memory (RAM) 1.00 GB Thanks Amare

  • How to benchmark functions in clojure

    - by Peter Tillemans
    I know I can get the time take to evaluate a function can be printed out on the screen/stdout using the time function/macro. The time macro returns the value of the evaluated function, which makes it great to use it inline. However I want to automatically measure the runtime under specific circumstances. is there a function which returns the elapsed time in some library to hep with this benchmarking?

  • Environment variable expansion in persistence.xml (JPA)

    - by user342495
    I am developing a Eclipse RCP plugin which uses JPA. I tried to specify the database path via a variable give to the JVM on runtime. The property is set correctly but the database is created in a folder named after the variable name (here: ${DBHOME}). <property name="javax.persistence.jdbc.url" value="jdbc:derby:${DBHOME};create=true"/> Is there a possibility to fix this? Thx

  • Smooth Text On Glass

    - by j-t-s
    Hi All I have seen many other samples out there that draw smooth text on glass. But I can't use them. I need every single label that gets added at runtime to be smooth. I can't just "draw" text onto the screen. Is this at all possible, and are there and sources around? Thank you

  • Lightweight Java reporting engine

    - by tuler
    I'm looking for a lightweight java reporting engine to be embedded in an applet application. My first option was Jasper Reports, but the jar is over 2Mb, a little too heavy (and too bloated) for my needs. I don't know if there is modular jasper distribution, with funcionalities split in several jars (like html rendering, pdf, excel, compilation, runtime, etc). I need to preview the report using Swing and print it. PDF export is a plus.

  • How do I mock/fake/replace/stub a base class at unit-test time in C#?

    - by MatthewMartin
    UPDATE: I've changed the wording of the question. Previously it was a yes/no question about if a base class could be changed at runtime. I may be working on mission impossible here, but I seem to be getting close. I want to extend a ASP.NET control, and I want my code to be unit testable. Also, I'd like to be able to fake behaviors of a real Label (namely things like ID generation, etc), which a real Label can't do in an nUnit host. Here a working example that makes assertions on something that depends on a real base class and something that doesn't-- in a more realistic unit test, the test would depend on both --i.e. an ID existing and some custom behavior. Anyhow the code says it better than I can: public class LabelWrapper : Label //Runtime //public class LabelWrapper : FakeLabel //Unit Test time { private readonly LabelLogic logic= new LabelLogic(); public override string Text { get { return logic.ProcessGetText(base.Text); } set { base.Text=logic.ProcessSetText(value); } } } //Ugh, now I have to test FakeLabelWrapper public class FakeLabelWrapper : FakeLabel //Unit Test time { private readonly LabelLogic logic= new LabelLogic(); public override string Text { get { return logic.ProcessGetText(base.Text); } set { base.Text=logic.ProcessSetText(value); } } } [TestFixture] public class UnitTest { [Test] public void Test() { //Wish this was LabelWrapper label = new LabelWrapper(new FakeBase()) LabelWrapper label = new LabelWrapper(); //FakeLabelWrapper label = new FakeLabelWrapper(); label.Text = "ToUpper"; Assert.AreEqual("TOUPPER",label.Text); StringWriter stringWriter = new StringWriter(); HtmlTextWriter writer = new HtmlTextWriter(stringWriter); label.RenderControl(writer); Assert.AreEqual(1,label.ID); Assert.AreEqual("<span>TOUPPER</span>", stringWriter.ToString()); } } public class FakeLabel { virtual public string Text { get; set; } public void RenderControl(TextWriter writer) { writer.Write("<span>" + Text + "</span>"); } } //System Under Test internal class LabelLogic { internal string ProcessGetText(string value) { return value.ToUpper(); } internal string ProcessSetText(string value) { return value.ToUpper(); } }

  • Why does this compile?

    - by akf
    I was taken aback earlier today when debugging some code to find that something like the following does not throw a compile-time exception: public Test () { HashMap map = (HashMap) getList(); } private List getList(){ return new ArrayList(); } As you can imagine, a ClassCastException is thrown at runtime, but can someone explain why the casting of a List to a HashMap is considered legal at compile time?

  • Why is my custom view not appearing?

    - by user351469
    When I comment out setContentView(boardView); in my Game.java my custom view in BoardView works fine and displays everything nicely... but onSizeChanged never gets called in BoardView.java... so I can't read the device width and height at runtime. If I leave setContentView uncommented onSizeChanged works... but the screen is blank! I want to be able to read the screen width and height at runtime and set the sizes of my ImageViews at creation so they are the optimal size. public class Game extends Activity implements OnClickListener{ private BoardView boardView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); boardView = new BoardView(this); setContentView(boardView); // when this line disabled, it looks ok boardView.requestFocus(); } public class BoardView extends View { private final Game game; private float width; // width of one unit private float height; // height of one unit public BoardView(Context context){ super(context); this.game = (Game)context; setFocusable(true); setFocusableInTouchMode(true); LinearLayout maincontainer = new LinearLayout(game); maincontainer.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)); maincontainer.setGravity(Gravity.CENTER); maincontainer.setOrientation(LinearLayout.VERTICAL); maincontainer.setBackgroundColor(Color.BLACK); LinearLayout innercontainer = new LinearLayout(game); innercontainer.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT)); innercontainer.setGravity(Gravity.CENTER); innercontainer.setOrientation(LinearLayout.HORIZONTAL); // declare a new table TableLayout layout = new TableLayout(game); layout.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT)); // build a grid of ImageViews in a TableLayout for (int f=1; f<=7; f++) { TableRow tr = new TableRow(game); for (int c=1; c<=7; c++) { ImageView b = new ImageView(game); b.setImageResource(R.drawable.neworb); b.setOnClickListener(game); tr.addView(b, 30,30); // I'd like to not use fixed values here } // for layout.addView(tr); } // for innercontainer.addView(layout); maincontainer.addView(innercontainer); game.setContentView(maincontainer); } @Override protected void onSizeChanged(int w, int h, int oldw, int oldh){ width = w/9f; height = width; super.onSizeChanged(w, h, oldw, oldh); } }
