Try-With-Resources: Ensuring Session Closure, AEM Code Example

In the dynamic realm of Java programming in AEM, effective resource management is a cornerstone of writing robust and reliable code. The “try-with-resources” statement, introduced in Java 7, emerges as a powerful ally in simplifying resource handling. This article delves into the practical implementation of “Try-With-Resources” within the context of a specific code snippet, emphasizing the importance of never forgetting to close the session.

The adoption of “Try-With-Resources” in your code exemplifies a commitment to clean, efficient, and error-resistant Java programming. By embracing this feature, you not only reduce boilerplate code but also mitigate the risk of resource leaks, ensuring the reliable closure of the session. The article underscores the significance of “Try-With-Resources” within the broader theme of never forgetting to close the session, offering developers valuable insights into crafting resilient and maintainable code.

Try-With-Resources AEM Example Code

final Map<String, Object> authInfo = Collections.singletonMap(

try (ResourceResolver resolver = factory.getServiceResourceResolver(authInfo)) {
    Session session = resolver.adaptTo(Session.class);
    Node contentNode = session.getNode("/content/sourcedcode/jcr:content");

    if (Objects.nonNull(contentNode)) {
        contentNode.setProperty("newProperty", "value");
        contentNode.setProperty("existingProperty", "value");
        contentNode.setProperty("existingProperty", (Value)null); // Remove property;
} catch (Exception e) {

In the spirit of “Try-With-Resources,” your code exemplifies the essence of effective resource management. The central focus is on ensuring the closure of the session resource, a critical component in Java Content Repository (JCR) operations.

Understanding the Code:

Within the try block, the “ResourceResolver” and its associated “Session” resource are declared using “Try-With-Resources.” The factory object, presumably an instance of a ResourceResolverFactory, facilitates obtaining a service resource resolver with specific authentication information (authInfo). The resolver is seamlessly adapted to a session, streamlining the process.

As the code interacts with the JCR node located at “/content/sourcedcode/jcr:content,” the session enables the manipulation of node properties. The try-with-resources statement guarantees that both the “ResourceResolver” and the “Session” are automatically closed at the conclusion of the block, eliminating the need for explicit closure statements.
