I cannot figure out what I am doing wrong here. I have tried all sorts of things, including absolute paths, relative, enabling logging (which also doesnt seem to be working, using Main, using DefaultCamelContext, adding threadsleep, but I cannot get camel to move a file from one folder to another.
Here is my code:
package scratchpad;
import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.dataformat.beanio.BeanIODataFormat;
import org.apache.camel.impl.DefaultCamelContext;
import org.apache.camel.main.Main;
import org.apache.camel.spi.DataFormat;
public class CamelMain {
private static Main main;
public static void main(String[] args) throws Exception {
main = new Main();
main.addRouteBuilder( new RouteBuilder() {
#Override
public void configure() throws Exception {
// DataFormat format = new BeanIODataFormat(
// "org/apache/camel/dataformat/beanio/mappings.xml",
// "orderFile");
System.out.println("starting route");
// a route which uses the bean io data format to format a CSV data
// to java objects
from("file://input?noop=true&startingDirectoryMustExist=true")
.to("file://output");
}
});
//main.run();
main.start();
Thread.sleep(5000);
main.stop();
}
}
Can someone spot anything wrong with the above?
Thanks
You can for example read from the free chapter 1 for the Camel in Action book, as it has a file copied example it covers from top to bottom.

We are trying cucumber serenity framework for end to end tests. I am fairly new the technology and I tired this simple code below.
actor.attemptsTo(Enter.theValue(path).into(Upload));
where path is the location of file i am trying to upload using browser's upload widget.Has anyone ever managed to perform actions like this using serenity screen play pattern.
Its really making us think of giving up serenity and just use cucumber-selenium framework as I can easily perform this using Upload.sendkeys(path);
Any help is much appreciated. Thanks in advance.
AS requested: Listing Steps:
public class ListingSteps
{
#Before
public void set_the_stage() {
OnStage.setTheStage(new OnlineCast());
}
#Given("^(.*) is able to click import products$") public void userIsAbleToClick(String actorName) throws Throwable
{
theActorCalled(actorName).wasAbleTo(Start.theApplication());
}
#When("^s?he imports a single item successfully$") public void heImportsASingleItemSuccessfully() throws Throwable
{
theActorInTheSpotlight().attemptsTo(Import.spreadsheet());
}
#Then("^(.*) are listed on ebay and amazon with all the right information$") public void itemsAreListedOnEbayAndAmazonWithAllTheRightInformation(String actorName, String SKU)
throws Throwable
{
//pending
}
Ignore then for now as its work in progress.
Import class:
public class Import implements Task
{
protected String path =
"C:\\somePathToFile\\populated_excel.xlsx";
public static Import spreadsheet()
{
return instrumented(Import.class);
}
#Override public <T extends Actor> void performAs(T actorName)
{
actorName.attemptsTo(Click.on(Products.ProductsScreen));
actorName.attemptsTo(Click.on(Products.Upload));
actorName.attemptsTo(Enter.theValue(path).into(Browse).thenHit(Keys.RETURN));//this is the line which is giving errors
actorName.attemptsTo(Click.on(Products.UploadButton));
}
}
Target Browse
public class Products
{
public static Target Browse = Target.the("browse file").locatedBy("//input[#type='file']");
}
Did you try removing these lines?
actorName.attemptsTo(Click.on(Products.ProductsScreen));
actorName.attemptsTo(Click.on(Products.Upload));
You don't need to open the upload file component, only write the file path directly to the input file element and perform the submit.
The way I managed to get this working was by using the FileToUpload class:
import net.thucydides.core.pages.components.FileToUpload;
FileToUpload fileToUpload = new FileToUpload(driver, fileName);
fileToUpload.fromLocalMachine().to(webElement);
I got this working with a simple:
import java.nio.file.*;
Path data = null;
try {
data = Paths.get(ClassLoader.getSystemResource(file).toURI());
} catch (URISyntaxException ignore) {}
ACTOR.attemptsTo(Upload.theFile(data).to(target));
file is an actual file that exists on your classpath, in src/test/resources if you have a Maven project.
target is something like:
Target.the("Image upload").located(By.xpath("//input[#type='file']"));
I would to ask about html2image, i have some codes like this
import gui.ava.html.image.generator.HtmlImageGenerator;
import java.io.File;
public class html2image {
public static void main(String[] args) {
HtmlImageGenerator imageGenerator = new HtmlImageGenerator();
imageGenerator.loadHtml("<b>Hello World!</b> Please goto <a title=\"Goto Google\" href=\"http://www.google.com\">Google</a>.");
imageGenerator.saveAsImage("hello-world.png");
imageGenerator.saveAsHtmlWithMap("hello-world.html", "hello-world.png");
}
}
But seems like after i call this java, its not appear any image or output image, maybe i miss some configuration, anyone can help ?
Try to give the absolute path in imageGenerator.saveAsImage as otherwise the file will be generated in the working directory.
I hava the following class which creates a .txt file
and writes data in this file.
package junitexport;
import java.io.FileWriter;
import java.io.IOException;
import org.junit.runner.JUnitCore;
public class ExecuteWithRunListener {
public static void main(String[] args) throws IOException {
String filename = "report.txt";
FileWriter fw = new FileWriter(filename,true);
fw.write("add a line");
fw.close();
JUnitCore runner = new JUnitCore();
runner.addListener(new ExecutionListener());
runner.run(MyUnitTest.class);
}
}
My question is how can I access the same file from another class.
import org.junit.runner.notification.Failure;
import org.junit.runner.notification.RunListener;
import junitexport.ExecuteWithRunListener;
public class ExecutionListener extends RunListener
{
/*
* Called when an atomic test is about to be started.
*/
public void testStarted(Description dsc) throws java.lang.Exception
{
//I want to write additional data to the previous file here
}
}
BR
As it is a text file, you can use Files.write()
public void testStarted(Description dsc) throws java.lang.Exception
{
Files.write(
Paths.get("report.txt"),
"the text you want to insert".getBytes(),
StandardOpenOption.APPEND
);
}
Use OO principles. Create a class to manage this functionality. Move your code from main into a public method and call this from both places.
Suggest a method to create the file and one to update the existing file
In your Unit Test source file, simple create a new instance of your newly created class and call the methods on this to test it.
I have a Sons class which load and play sounds. And an adhd class which contain the main and uses this Sons class.
All my classes are in the package "adhd" and my sounds in the jar, are like this : 1.wav is in SoundN which is in the jar. (ADHD.jar/SoundN/1.wav).
When I run the code in Eclipse it works, but when I run the jar it doesn't. It is important for me to keep the sounds "loading" because I need my program to read my sounds quickly, as I am using timers. What do you suggest me to do?
Here is the code of my class Sons which load sounds in instances of singletons.
Sons
package adhd;
import java.io.File;
import java.io.IOException;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.FloatControl;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;
import javax.sound.sampled.UnsupportedAudioFileException;
import java.applet.Applet;
import java.applet.AudioClip;
import java.net.URL;
public class Sons {
private static String PATH=null;
private static Sons instance;
private final Map<String, Clip> sons;
private boolean desactive;
Sons(String path) {
PATH = path;
sons = new HashMap<String, Clip>();
}
public void load(String nom) throws UnsupportedAudioFileException, IOException, LineUnavailableException {
Clip clip = AudioSystem.getClip();
clip.open(AudioSystem.getAudioInputStream(getClass().getResourceAsStream(PATH + nom)));
sons.put(nom, clip);
}
public void play(String son) {
if(!desactive) try {
Clip c = getSon(son);
c.setFramePosition(0);
c.start();
} catch(Exception e) {
System.err.println("Impossible to play the sound " + sound);
desactive = true;
}
}
}
Here is the adhd class which contain the main that uses sounds
Main class : adhd
public static void main(String[] args) {
Sons sonN= new Sons("/SoundN/");
try {
sonN.load("1.wav");
} catch (UnsupportedAudioFileException | IOException
| LineUnavailableException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
sonN.play("1.wav");
}
Here is also a picture of the tree
Now, thanks to the exception message, we know what the problem actually is. The problem is not that the sounds can't be loaded or aren't found in the jar. The problem is that, as the javadoc says:
These parsers must be able to mark the stream, read enough data to determine whether they support the stream, and, if not, reset the stream's read pointer to its original position. If the input stream does not support these operation, this method may fail with an IOException.
And the stream returned by Class.getResourceAsStream(), when the resource is loaded from a jar, doesn't support these operations. So what you could do is to read everything from the input stream into a byte array in memory, create a ByteArrayInputStream from this byte array, and pass that stream to AudioSystem.getAudioInputStream().
If loading everything in memory is not an option because the sound is really long (but then I guess you wouldn't put it in the jar), then you could write it to a temporary file, and then pass a FileInputStream to AudioSystem.getAudioInputStream().
Hi I am a novice in JAVA. I have been getting this file not found exception inspite of the file existing in the very location I have specified in the path which is
Initially I had the issue of file not found. However, after performing a clean and re-run, now I am having an issue which says
Error: Could not find or load main class main.main
import Message.*;
import java.util.*;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.PrintWriter;
public class main{
public static void main(String[] args) {
Message msg=new Message("bob","alice","request","Data####");
MPasser passerObj=new MPasser("C:\\Workspace\\config.txt","process1");
}
}
Also in the MPasser Constructor the following piece of relevant code is there
public class MPasser(String file_name,String someVariable){
InputStream input;
try {
input =new RandomAccessFile(file_name,"r");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Yaml yaml = new Yaml();
Map<String, String> Object = (Map<String, String>) yaml.load(input);
}
Sorry I have made edits from initial query so that it is more clear
On this line:
input = RandomAccessFile("C:\Workspace\conf.txt",'r');
You need to escape the \'s
input = RandomAccessFile("C:\\Workspace\\conf.txt",'r');
"C:\Workspace\conf.txt"
Those are escape sequences. You probably meant:
"C:\\Workspace\\conf.txt"
You also appear to call it config.txt in one snippet and conf.txt in the other?
Make sure the java process has permissions to read the file.
You have to escape the backslash.
input = RandomAccessFile("C:\\Workspace\\conf.txt",'r');
and also
input = new RandomAccessFile("C:\\Workspace\\conf.txt",'r');
and why you have two different filename conf.txt and config.txt.
