    TestGameTable.class.getResource(&quot;/unibo/lsb/res/dice.jpg&quot;);

- leading slash to denote the root of the classpath
- slashes instead of dots in the path
- you can call `getResource()` directly on the class.

Instead of explicitly writing the class name you could use

    this.getClass().getResource(&quot;/unibo/lsb/res/dice.jpg&quot;);

if you are calling from `static` method, use :

    TestGameTable.class.getClassLoader().getResource(&quot;dice.jpg&quot;);

One thing to keep in mind is that the relevant path here is the path relative to the file system location of your class... in your case TestGameTable.**class**.  It is not related to the location of the TestGameTable.**java** file.  
I left a more detailed answer here...  [where is resource actually located][1]

I have a project where I have multiple instances of an app running, each of which was started with different command line arguments. I&#39;d like to have a way to click a button from one of those instances which then shuts down all of the instances and starts them back up again with the same command line arguments.

I can get the processes themselves easily enough through `Process.GetProcessesByName()`, but whenever I do, the `StartInfo.Arguments` property is always an empty string. It looks like maybe that property is only valid before starting a process.

[This question][1] had some suggestions, but they&#39;re all in native code, and I&#39;d like to do this directly from .NET. Any suggestions?

I need to add some lightweight syntactic sugar to JavaScript source code, and process it using a JavaScript-based build system. Are there any open source JavaScript parsers written in JavaScript? And are they reasonably fast when run on top of V8 or a similar high-performance JavaScript implementation?

Thank you for any pointers you can provide!

I need to get a resource image file in a java project. What I&#39;m doing is:

    URL url = TestGameTable.class.getClass().
              getClassLoader().getResource(&quot;unibo.lsb.res/dice.jpg&quot;);

The directory structure is the following:

    unibo/
      lsb/
        res/
          dice.jpg
        test/
        ..../ /* other packages */

The fact is that I always get as the file doesn&#39;t exist. I have tried many different paths, but I couldn&#39;t solve the issue.
Any hint?

I have a string representing an URL containing spaces and want to convert it to an URI object. If I simply try to create it via

    String myString = &quot;http://myhost.com/media/File Name that has spaces inside.mp3&quot;;
    URI myUri = new URI(myString);

it gives me 

    java.net.URISyntaxException: Illegal character in path at index X

where index `X` is the position of the first space in the URL string.

How can i parse `myString` into a `URI` object?

I want to fetch the id of a one-to-one relationship without loading the entire object.  I thought I could do this using lazy loading as follows:

    class Foo { 
        @OneToOne(fetch = FetchType.LAZY, optional = false)
        private Bar bar; 
    }


    Foo f = session.get(Foo.class, fooId);  // Hibernate fetches Foo 

    f.getBar();  // Hibernate fetches full Bar object
   
    f.getBar().getId();  // No further fetch, returns id

I want f.getBar() to *not* trigger another fetch.  I want hibernate to give me a proxy object that allows me to call .getId() without actually fetching the Bar object.  

What am I doing wrong?

I am learning JPA and have confusion in the `@SequenceGenerator` annotation.

To my understanding, it automatically assigns a value to the numeric identity fields/properties of an entity.

**Q1.** Does this sequence generator make use of the database&#39;s increasing numeric value generating capability or generates the number on its own?

**Q2.** If JPA uses a database auto-increment feature, then will it work with datastores that don&#39;t have an auto-increment feature?

**Q3.** If JPA generates numeric value on his own, then how does the JPA implementation know which value to generate next? Does it consult with the database first to see what value was stored last in order to generate the value (last + 1)?

---
**Q4.** Please also shed some light on `sequenceName` and `allocationSize` properties of `@SequenceGenerator` annotation.

I have a date string and I want to parse it to normal date use the java Date API,the following is my code:

	public static void main(String[] args) {
		String date=&quot;2010-10-02T12:23:23Z&quot;;
		String pattern=&quot;yyyy-MM-ddThh:mm:ssZ&quot;;
		SimpleDateFormat sdf=new SimpleDateFormat(pattern);
		try {
			Date d=sdf.parse(date);
			System.out.println(d.getYear());
		} catch (ParseException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

However I got an exception: `java.lang.IllegalArgumentException: Illegal pattern character &#39;T&#39;`

So I wonder if I have to split the string and parse it manually?

BTW, I have tried to add a single quote character on either side of the T:   

    String pattern=&quot;yyyy-MM-dd&#39;T&#39;hh:mm:ssZ&quot;;

It also does not work.

Can somebody suggest an easy way to get a reference to a file as a String/InputStream/File/etc type object in a junit test class?  Obviously I could paste the file (xml in this case) in as a giant String or read it in as a file but is there a shortcut specific to Junit like this?

    public class MyTestClass{
    
    @Resource(path=&quot;something.xml&quot;)
    File myTestFile;
    
    @Test
    public void toSomeTest(){
    ...
    }
    
    }

Android comes with lots of system resources (`android.R`) that can be used to save you time and make your application lighter.

For example, I recently discovered that Android provides localized strings for Yes (`android.R.string.yes`), No (`android.R.string.no`), Cancel (`android.R.string.cancel`) and Ok (`android.R.string.ok`), among other strings.

What other system resources do you recommend using? Or is there a reason to avoid using system resources?

Edit: As noted by Tomas, some of this resources might not produce the results you would expect (particularly, `android.R.string.yes/no` returns `OK/Cancel` instead of `Yes/No`, as reported [here][1]). For greater control, you can copy system resources from the Android source code.

Before going much further i&#39;ll mention I have tried solutions in following:

https://stackoverflow.com/questions/320677/how-do-i-set-the-icon-for-my-application-in-visual-studio-2008

https://stackoverflow.com/questions/198848/set-application-icon-from-resources-in-vs-05

I am trying to set an icon for my application.

AFAIK, I need potentially 3 images?

- 1 image is the actual image in explorer when clicking on the .exe (thumbnail for the exe)
- 1 image (tiny) in the top left corner (16 x 16? Not entirely sure)
- 1 image in the start menu dock, to the left of the app (maybe 32x32? again not sure)

So thats fine.

Now I have selected an Icon. How do I use it in one of above situations?

I have tried adding it in resources, nothing seems to happen. Following that first SO solution, 

&lt;i&gt;&quot;First go to Resource View (from menu: View --&gt; Other Window --&gt; Resource View). Then in Resource View navigate through resources, if any. If there is already a resource of Icon type, added by Visual Studio, then open and edit it. Otherwise right-click and select Add Resource, and then add a new icon.&quot;&lt;/i&gt;

The resource view is empty, and I cannot right click in this view.

If I right click on the solution &gt; properties &gt; resources &gt; I can add the icon image, but it doesn&#39;t show in either of the locations listed above. (or anywhere that I can see)

I&#39;m having trouble when one of the jars that my web app depends on tries to load a properties file from within the jar.  Here is the code in the jar.

	static
	{
		Properties props = new Properties();
        try 
        {
			props.load(ClassLoader.getSystemResourceAsStream(&quot;someProps.properties&quot;));
		} catch (IOException e) 
		{
			e.printStackTrace();
		}
		someProperty = props.getProperty(&quot;someKey&quot;);
	}

The properties file is in my &quot;src/main/resources&quot; directory of the Maven project.  When I run this code from my junit test in Eclipse, it executes just fine.  When the project is built with Maven into a jar, and included as a dependency in my web app, it fails to locate the properties file.  I know that the properties file is at the base directory of the depended on jar, I don&#39;t know how to fix this.

How can I use `ClassLoader.getResources()` to find recursivly resources from my classpath?

E.g. 

- finding all resources in the `META-INF` &quot;directory&quot;:
  Imagine something like 

  `getClass().getClassLoader().getResources(&quot;META-INF&quot;)`

 Unfortunately, this does only retrieve an `URL` to exactly this &quot;directory&quot;.

- all resources named `bla.xml` (recursivly)

  `getClass().getClassLoader().getResources(&quot;bla.xml&quot;)`

 But this returns an empty `Enumeration`.

And as a bonus question: How does `ClassLoader.getResources()` differ from `ClassLoader.getResource()`?





How to use ClassLoader.getResources() correctly?

I wonder what the difference is between `Class.getResource()` and `ClassLoader.getResource()`?

*edit: I especially want to know if any caching is involved on file/directory level. As in &quot;are directory listings cached in the Class version?&quot;*

AFAIK the following should essentially do the same, but they are not:

    getClass().getResource() 
    getClass().getClassLoader().getResource()

I discovered this when fiddling with some report generation code that creates a new file in `WEB-INF/classes/` from an existing file in that directory. When using the method from Class, I could find files that were there at deployment using `getClass().getResource()`, but when trying to fetch the newly created file, I recieved a null object. Browsing the directory clearly shows that the new file is there. The filenames were prepended with a forward slash as in &quot;/myFile.txt&quot;.

The `ClassLoader` version of `getResource()` on the other hand did find the generated file. From this experience it seems that there is some kind of caching of the directory listing going on. Am I right, and if so, where is this documented?

From the [API docs][1] on `Class.getResource()`
&gt; Finds a resource
&gt; with a given name. The rules for
&gt; searching resources associated with a
&gt; given class are implemented by the
&gt; defining class loader of the class.
&gt; This method delegates to this object&#39;s
&gt; class loader. If this object was
&gt; loaded by the bootstrap class loader,
&gt; the method delegates to
&gt; ClassLoader.getSystemResource(java.lang.String).

To me, this reads &quot;Class.getResource is really calling its own classloader&#39;s getResource()&quot;. Which would be the same as doing `getClass().getClassLoader().getResource()`. But it is obviously not. Could someone please provide me with some illumination into this matter?
