How to Set Up Session Replay in Java

Reproducing bugs in Java is time-consuming. Session replay eliminates guesswork by showing you the user's exact journey leading to the error.

Why Session Replay Matters for Java

Java applications face unique challenges in production environments. Network failures, unexpected input, third-party API changes, and edge cases all contribute to runtime issues that are difficult to catch during development. Proper session replay with Bugsly gives your team actionable data — including stack traces, request context, and environment details — so you can resolve issues quickly.

Setting Up Bugsly for Java

1. Install the Bugsly SDK for your Java project:

implementation 'io.bugsly:bugsly-java'

1. Initialize Bugsly in your application entry point:

import io.bugsly.Bugsly;

public class Application {
    public static void main(String[] args) {
        Bugsly.init(options -> {
            options.setDsn("YOUR_BUGSLY_DSN");
            options.setTracesSampleRate(1.0);
        });
    }
}

1. Verify the integration by triggering a test event. Bugsly will capture it and display it in your dashboard within seconds.

1. Configure alert rules in the Bugsly dashboard to get notified via Slack, email, or webhook when new issues appear.

What You Get

Once configured, Bugsly automatically captures unhandled exceptions, groups similar errors, and provides detailed context for each event. You'll see stack traces, breadcrumbs showing what happened before the error, and release tracking to correlate issues with deployments. The Java integration hooks into the framework's lifecycle, so you get relevant context without manual instrumentation.

Next Steps

Once session replay is running, configure privacy rules to mask sensitive user data like passwords and credit card fields. Use replay search to find sessions matching specific criteria — like sessions with rage clicks or error events. Connect replays to error reports for instant visual context during debugging.
