Object Storage - Can't access container in region "London"

Question

I have created a contained through dashboard in region "London". But when I try to access it, the program checks -apparently as default region as also stated here- only the region "Dallas" even though the region in my credentials is "London". I tried to create a container through my program and the container was created in the region "Dallas".

How can I make my program access the container in region "London"? Any advice on how to specify the region is appreciated.

My code to list containers looks like below;

final private OSClient os;

public ObjectStorageDAO(String url, String userId, String password, String project, String domainName)
        throws Exception {

    Identifier domainIdentifier = Identifier.byName(domainName);
    Identifier projectIdentifier = Identifier.byName(project);

    os = OSFactory.builderV3().endpoint(url).credentials(userId, password)
            .scopeToProject(projectIdentifier, domainIdentifier).authenticate();
}

/**
 * Returns the list of containers under the account
 */
public List containers() {
    return os.objectStorage().containers().list();
}

Answer 1

After initiating the os object, can you try forcing the region?

final private OSClient os;

public ObjectStorageDAO(String url, String userId, String password, String project, String domainName)
        throws Exception {

    Identifier domainIdentifier = Identifier.byName(domainName);
    Identifier projectIdentifier = Identifier.byName(project);

    os = OSFactory.builderV3().endpoint(url).credentials(userId, password)
            .scopeToProject(projectIdentifier, domainIdentifier).authenticate();

    /////////////////////////
    // force london region //
    /////////////////////////

    os.useRegion('london')
}

/**
 * Returns the list of containers under the account
 */
public List containers() {
    return os.objectStorage().containers().list();
}
