wcs2:post-xml-req5 fails with InvocationTargetException (post/xml)

[lgoltz]

Setup

SUT: TODO
Selected CCs: all, except WCS WPS 2.0 (Processing)
Tested locally with docker environment

• ETS WCS 2. 0 1.13-SNAPSHOT
• TEAM Engine 5.2-SNAPSHOT

Testfailure

"Error in call to extension function {public org.w3c.dom.NodeList com.occamlab.te.TECore.request(org.w3c.dom.Document,java.lang.String) throws java.lang.Throwable}: Exception in extension function java.lang.reflect.InvocationTargetException"

• Service returns a multipart response. ETS fails with the following failure (error_log.txt):

Caused by: java.lang.RuntimeException: Failed to parse resource from https://ogc.webgistesting.net/server/services/Mynetcdf/ImageServer/WCSServer 
 Failed to parse input: sun.net.www.protocol.http.HttpURLConnection$HttpInputStream
        at com.occamlab.te.parsers.XMLValidatingParser.parse(XMLValidatingParser.java:222)
        ... 83 more

Proposal

• Further investigations required

[lgoltz]

The failure occurs cause the GetCoverage Response is tried to be parsed as XML but the respone is a multipart.
The service http://moon.planetserver.eu:8084/rasdaman/ows?service=WCS&request=GetCapabilities&acceptversions=2.0.1 returns XML (gmlcov:RectifiedGridCoverage). It must be checked if the behaviour of the service is correct.

@lgoltz

Service is not available to reproduce this behavior. Could you please provide any other service which will reproduce the same behavior?

[keshavnangare]

@lgoltz @dstenger

I have tested the Zikang's service and test gets failed with the same error.

Lyn, you are right the service response is multipart so the XMLValidatingparser is failed to parse the multipart data because it expecting the only XML.

I don't see a reason why multipart should be forbidden.

Thus, there must either a precondition be defined for test suite or multipart support must be enabled.

[lgoltz]

@keshav-nangare: Can you check if multipart support can be enabled in the test suite?

[ghobona]

@keshav-nangare

If it's a .tif image then you could use Java's ImageIO class to check whether it is an image.

For example, the sample code below returns the width and height of an image if the file is an image. If the file is not an image, then an Exception is thrown.

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.imageio.ImageIO;

public class NewClass {
    public static void main(String[] args) {
        try {
            BufferedImage bi = ImageIO.read(new File("/Users/ogccite/Downloads/myimage.tif"));
             System.out.println("Check "+bi.getHeight()+ " "+ bi.getWidth());            
        } catch (IOException ex) {
            Logger.getLogger(NewClass.class.getName()).log(Level.SEVERE, null, ex);
        }
    }    
}

@keshav-nangare @ghobona discussed on 2020-07-15.

This issue is related to opengeospatial/ets-wcs11#41 because of the multipart aspect.

They may have the same solution.

[keshavnangare]

Discussed on 22-07-2020 with @dstenger and @ghobona

Proposed solution:

Add validation for a response with following content-type:

"image/*" OR "application/x-hdf5"

If the response has above content-type then test should pass otherwise fail

Fixed with #98 PR.
