The following code with Rascal will not work:
module Exercise1
import IO;
import IO;
import lang::java::jdt::m3::Core;
public void testing()
{
M3 model = createM3FromEclipseProject(|project://JabberPoint/|);
for (<a,b> <- model.extends)
println("<a> extends <b>");
}
It results with:
|plugin://rascal_eclipse/src/org/rascalmpl/eclipse/library/lang/java/jdt/m3/Core.rsc|(392,187,<13,0>,<15,90>): Java("NullPointerException","")
at org.eclipse.jdt.core.dom.CompilationUnitResolver.resolve(|unknown:///CompilationUnitResolver.java|(0,0,<599,0>,<599,0>))

at org.rascalmpl.eclipse.library.lang.java.jdt.m3.internal.EclipseJavaCompiler.compileAllFiles(|unknown:///EclipseJavaCompiler.java|(0,0,<88,0>,<88,0>))....
What could be the problem?
Thanks.

I am trying to run parallel test through selenium grid.
I know I have to use "thread local" for parallel execution,
but I have a problem with my code.
Cannot invoke "io.appium.java_client.android.AndroidDriver.findElementByAccessibilityId(String)" because "driver" is null

call getdriver() method of your class _2_Deviceinfo to your test class.
Appiumdriver<?> driver = getDriver();
MobileElement arrow = driver.findElementByAccessibilityId("next");
arrow.click();

I am new to Appium and just getting started, I would like to call methods from other classes by creating an object. but when I call methods it show "this.driver" is null. how to call methods from other class by creating object?? is it possible??

The methods in AllMethods class are referring to the driver which is not yet initialized. i.e they are referring to this driver :
public AndroidDriver<AndroidElement> driver;
You will need to add this.driver=driver inside AllMethods constructor, this will set the driver with the reference of the driver that is passed in the constructor.
Following
https://christiandietrich.wordpress.com/2011/10/15/xtext-calling-the-generator-from-a-context-menu/
and using EclipseResourceFileSystemAccess2 instead of EclipseResourceFileSystemAccess when the line
final EclipseResourceFileSystemAccess2 fsa = fileAccessProvider.get();
give an exception. The only information I have is
// Compiled from InvocationTargetException.java (version 1.8 : 52.0, super bit)
public class java.lang.reflect.InvocationTargetException extends java.lang.ReflectiveOperationException {
I don't know how to get the stack trace in Eclipse.
does the code in the blog still function in the most recent release of Xtext?

it basically works, if you do the update from EclipseResourceFileSystemAccess and Stuff and (maybe) IGenerator.
I assume in your case you dont set the Accesses ProgressMonitor and other props.

and make sure you register the handler properly.
the

is crucial, especially that it consists of 2 parts, the ExtensionFactory followed by a : followed by the actual class name
I downloaded the Jester example code in Mahout, and tries to run it on jester dataset to see the evaluation results. the running is done successfully, but the console only has the results:
log4j:WARN No appenders could be found for logger (org.apache.mahout.cf.taste.impl.model.file.FileDataModel).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
I expect to see the evaluation score range from 0 to 10. any one can help me found out how to get the score?

Mahout 0.7 is old, and 0.6 is very old. Use at least 0.7, or better, later from SVN.
I think the problem is exactly what you identified: you don't have any slf4j bindings in your classpath. If you use the ".job" files in Mahout you will have all dependencies packages. Then you will actually see output.
