Example 95 with PersistenceException

use of org.apache.sling.api.resource.PersistenceException in project sling by apache.

the class MongoDBNoSqlResourceProviderIT method testRoot.

@Override
protected Resource testRoot() {
    if (this.testRoot == null) {
        try {
            Resource root = context.resourceResolver().getResource("/");
            Resource providerRoot = root.getChild("test");
            if (providerRoot == null) {
                providerRoot = context.resourceResolver().create(root, "test", ImmutableMap.<String, Object>of(JcrConstants.JCR_PRIMARYTYPE, JcrConstants.NT_UNSTRUCTURED));
