Can't open ressource file in Arquillian test

Question

I want to read a test CSV file (xxx.csv) in my integration test using arquillian. I am packing my archive as follows:

@Deployment
public static WebArchive createDeployment() {
    WebArchive archive = ShrinkWrap.create(WebArchive.class);
    archive.addClasses(FileReader.class, FileWriteService.class, MockDataFactory.class, CSVFileReader.class, ExcelFileReader.class);
    archive.addAsResource("config.properties").addAsResource("xxx.csv");
    System.out.println(archive.toString(true));
    return archive;
}

Where the print shows me:

> 7fadc596-9353-4cac-aacc-cf5ec5d94c16.war: /WEB-INF/
> /WEB-INF/classes/ /WEB-INF/classes/config.properties
> /WEB-INF/classes/com/ /WEB-INF/classes/com/goodgamestudios/
> /WEB-INF/classes/com/goodgamestudios/icosphere/
> /WEB-INF/classes/com/goodgamestudios/icosphere/service/
> /WEB-INF/classes/com/goodgamestudios/icosphere/service/fileReader/

> /WEB-INF/classes/com/goodgamestudios/icosphere/service/fileReader/ExcelFileReader$1.class
> /WEB-INF/classes/com/goodgamestudios/icosphere/service/fileReader/FileReader.class
> /WEB-INF/classes/com/goodgamestudios/icosphere/service/fileWriter/
> /WEB-INF/classes/com/goodgamestudios/icosphere/service/fileWriter/FileWriteService.class
> /WEB-INF/classes/com/goodgamestudios/icosphere/datamodel/
> /WEB-INF/classes/com/goodgamestudios/icosphere/datamodel/MockData/
> /WEB-INF/classes/com/goodgamestudios/icosphere/datamodel/MockData/MockDataFactory.class
> /WEB-INF/classes/xxx.csv

As you can see, the file is clearly in the archive (last row).

Now I am trying to open it. I have tried:

private File getFile(String filename) throws IOException {
    return convertInputStreamToFileHelper(getClass().getResourceAsStream(filename), filename);
}

new File(this.getClass().getResource("/xxx.csv").getFile()

new File("/xxx.csv")

new File("xxx.csv")

but none would work.

what app server are you running? Where are you trying to open the file, in your test, or within a class also packaged in the .war file? — Tea Curran, Sep 22 '15 at 15:54

You can get InputStream: this.getClass().getResourceAsStream("/xxx.csv"), but it is not possible to get File object for packed resources inside war. If you need File object you can copy InputStream content to tmp file.

Jup, getRessourceAsStream(filename) was indeed working, thanks! – olkoza Sep 24 '15 at 12:08

You have to use the full path to the file. In order to try check out the following code:

URL fileURL = this.getClass().getResource("/WEB-INF/classes/xxx.csv");
System.out.println(fileURL);

You should get a URL different that null.

Be careful with getResource because I think it is case sensitive. At least I had issues with that.

Url comes out to null. – olkoza Sep 18 '15 at 11:48
I made a test on my end and worked with the path from the previous comment... Maybe you try opening the war manually and checking if the file is really there? I know you already checked that in the trace, but just to make sure. – narko Sep 18 '15 at 12:12

I think it always depends on the application server you use and its classpath settings!

F.ex. here I have a file in test/resources, and I set the destination as WEB-INF/classes/file, where Wildfly (JBoss) will find it:

.addAsWebInfResource("file.txt",
                     "classes/file.txt")

using:

final InputStream inStream = this.getClass().getClassLoader()
                                .getResourceAsStream(fileName);
