As someone new to Mongo, I am looking for a sample MongoDB database that I can import and play with.
Something along the lines of [world][1] for mysql or [Northwind][2] for MSSQL.


Is there one? (I couldn&#39;t find any reference to one at http://www.mongodb.org nor did my googling help)

I have a small Java project in Eclipse. I have a class of JUnit tests for each class in the project. I&#39;m using JUnit 4, and this is not a maven project.

Is there an easy way to tell Eclipse to run all tests in all test classes at once?

I&#39;ve got a H2 database with URL `&quot;jdbc:h2:test&quot;`. I create a table using `CREATE TABLE PERSON (ID INT PRIMARY KEY, FIRSTNAME VARCHAR(64), LASTNAME VARCHAR(64));`. I then select everything from this (empty) table using `SELECT * FROM PERSON`. So far, so good.

However, if I change the URL to `&quot;jdbc:h2:mem:test&quot;`, the only difference being the database is now in memory only, this gives me an `org.h2.jdbc.JdbcSQLException: Table &quot;PERSON&quot; not found; SQL statement: SELECT * FROM PERSON [42102-154]`. I&#39;m probably missing something simple here, but any help would be appreciated.

I am not sure it is me or what but I am having a problem converting a double to string.

here is my code:

    double total = 44;
    String total2 = Double.toString(total);

Am i doing something wrong or am i missing a step here.

I get error `NumberFormatException` when trying to convert this.

    totalCost.setOnTouchListener(new OnTouchListener() {
      public boolean onTouch(View v, MotionEvent event) {
        try {
          double priceG = Double.parseDouble(priceGal.getText().toString());
          double valG = Double.parseDouble(volGal.toString());
          double total = priceG * valG;
          String tot = new Double(total).toString();
          totalCost.setText(tot);
        } catch(Exception e) {
          Log.e(&quot;text&quot;, e.toString());
        }
					
        return false;
      }			
    });


I am trying to do this in an onTouchListener. Ill post more code, basically when the user touches the edittext box i want the information to calculate a fill the edittext box.

I am trying to create a new project from existing source code. I keep getting the following error: &quot;Invalid Project Description&quot;, project path &quot;overlaps the location of another project&quot; with the same name. The reason is that I created that project from the source code before, but then I deleted that project and deleted its whole directory, before adding the source code directory again. I tried everything like cleaning and restarting, but nothing worked. I looked in my workspace directory, but there are no traces for the old project.
There are several questions around this problem such as this https://stackoverflow.com/q/5044151/724195, but none of the answers worked for me!

Eclipse &quot;Invalid Project Description&quot; when creating new project from existing source

When editing XML files in the editor for Eclipse, line numbers are not displayed.

Use case:

I create a layout with many views, one of these lacks android:layout_width attribute. This causes a runtime error when the binary XML layout resource is inflated. The error log tells me to check like 361 in my XML file. 

Thanks to the line number being displayed I can find the offending line and make the change without having to open the file in another editor.

No line numbers in Eclipse or Android Studio XML editor

I am working with Eclipse 3.7, on an Windows XP environment behind a web proxy.

I want to install the [Groovy plugin][1] on a *newly unzipped* Eclipse Indigo (*Eclipse Java EE Indigo M4*).
I added the [update site][2] to the `Available Software Site` list.

But Eclipse is not able to retrieve the information of this plugin, and thus the installation is not possible...

If I put `Native` configuration in `General &gt; Network Connections`, which does not have the `Auth` option selected, I get the following error when I trying to reach the update site:

    HTTP Proxy Authentication Required: http://dist.codehaus.org/groovy/distributions/greclipse/snapshot/e3.7/content.xml
    HTTP Proxy Authentication Required: http://dist.codehaus.org/groovy/distributions/greclipse/snapshot/e3.7/content.xml
    Proxy Authentication Required

So now, I select `manual`, I define all correct information for the three schemas (HTTP, HTTPS, SOCKS): proxy, port, Auth, User and password.
However, when I try to reach the update site, Eclipse is indicating that he is `Fetching children of Groovy Eclipse`, but keep this status at 0%...

What is strange is that even if I put a wrong password in the `General &gt; Network Connections` configuration, I don&#39;t get any error message.

**My questions:**

* What is wrong in my configuration?
* Is there another way to define the proxy configuration? 
* Is there a way to get more information, to know what Eclipse is trying to do (the `workspace/.metadata/.log` doesn&#39;t contain any useful information) ? 

Another problem (minor however) is that the modifications of the proxy settings seem to be handled only after an Eclipse restart.

---------

*ps1:* Using my browser, I can reach the update site, so it is not blocked by the proxy.

*ps2:* This problem is not related to this plugin, as Eclipse behaves the same way for other plugin.

*ps3:* Here is the content of the `workspace/.metadata/.log` when I start Eclipse and try to install the plugin (all these logs are written during the startup, none when Eclipse tries to access the update site)

I have added a **2.45mb** jar file to my Android eclipse project and now I continue to get &quot;Conversion to Dalvik format failed: Unable to execute dex: Java heap space&quot; no matter what I do. 

I have researched online, and was informed to update my eclipse.ini to increase my Java VM heapsizes. I have done this for all the values in eclipse.ini and I continue to get the build error.

Any ideas?

I am trying to build a simple Java project with Maven. In my pom-file I declare JUnit 4.8.2 as the only dependency. Still Maven insists on using JUnit version 3.8.1. How do I fix it?

The problem manifests itself in a compilation failure: &quot;package org.junit does not exist&quot;. This is because of the import statement in my source code. The correct package name in JUnit 4.* is org.junit.* while in version 3.* it is junit.framework.*

I think I have found documentation on the root of the problem on http://maven.apache.org/plugins/maven-surefire-plugin/examples/junit.html but the advice there seems to be meant for Maven experts. I did not understand what to do.

Maven 3 and JUnit 4 compilation problem: package org.junit does not exist

I&#39;m attempting to write some tests using the built-in android Junit testing framework.  I am running into a problem with a test where I am expecting an exception to be thrown.  In JUnit, the annotation for the test method would be: 

`@Test(expected = ArithmeticException.class)`

However, in Android, this test fails with an ArithmeticException.

I understand that the Android implementation is only a subset of JUnit 3, and doesn&#39;t even allow the annotation @Test (must be @SmallTest, @MediumTest, or @LargeTest, and none of those allow for the &#39;expected=..&#39; parameter), but this seems like a fairly significant test, and seems like the Android testing framework would be seriously lacking if it did not have this feature.

**Note :**  I tested this by adding the JUnit jar to the project and by adding and the annotations to my test methods.  It makes sense to me why the annotations would be completely ignored because the Android framework (runner?) is not looking for that annotation and just ignores it.  Basically, I&#39;m just looking for the &#39;right&#39; way to do this within the framework. 

Android JUnit Testing ... How to Expect an Exception

I have a legacy class that contains a `new()` call to instantiate a `LoginContext` object:

    public class TestedClass {
      public LoginContext login(String user, String password) {
        LoginContext lc = new LoginContext(&quot;login&quot;, callbackHandler);
      }
    }

I want to test this class using Mockito to mock the `LoginContext` as it requires that the JAAS security stuff be set up before instantiating, but I&#39;m not sure how to do that without changing the `login()` method to externalize the `LoginContext`.

Is it possible using Mockito to mock the `LoginContext` class?

The javadocs for JUnit are surprisingly lacking, considerings its wide use. Can you show me how to use the new `assertEquals(double expected, double actual, double epsilon)`?

I&#39;m a newbie to unit testing and Junit. I know the basics of Junit. I just started learning about the EasyMock framework.

I couldn&#39;t understand the use of `replay()` method.

Could anyone please provide some info?

I understand the use of `EasyMock.expect()` and `EasyMock.verify()`.
