Mime type exception when validating BDOC container

[hello96]

Hi everyone! I'm getting a strange error when trying to validate a BDOC container:

My code:

                Container container = ContainerBuilder.aContainer(DocumentType.BDOC)
                .fromExistingFile(bdocFileName)
                .build();

        // Validate the container
        ContainerValidationResult result = container.validate();

        // Check if the container is valid
        boolean isContainerValid = result.isValid();

        // Get the validation errors and warnings
        List<DigiDoc4JException> validationErrors = result.getErrors();
        List<DigiDoc4JException> validationWarnings = result.getWarnings();
        List<DigiDoc4JException> containerErrors = result.getContainerErrors();// Container format errors
        List<DigiDoc4JException> containerWarnings = result.getContainerWarnings();

        String validationReport = result.getReport();

        result.saveXmlReports(reportFileName));
        System.out.println(validationErrors);

I think that the issue might concern this function in the ContainerOpener.java class:

In fact, in the read() function at line 126 it crushes by throwing the mentioned exception, assuming that it is an ASIC container before doing the checks that would follow.

Am I doing something wrong?

Hello, @hello96!

Is the mime type of the container defined as application/vnd.bdoc-1.0 (found in mimetype file)? Could you please send your container to help@ria.ee so we can analyze further.

Today DigiDoc4j does support only ASIC-E standard based BDOC containers and in accordance of BDOC2.1 standard only mime type application/vnd.etsi.asic-e+zip is allowed. More information on the subject can be found here:
