[BridgeLink 4.6.0] How to load external JARs (AWS SDK) programmatically without manual Resources UI configuration?

[jewelbonnie]

Hi team 👋,

I'm working with BridgeLink Administrator 4.6.0 and need help with automating external JAR loading for our CI/CD pipeline.

Environment

• BridgeLink: 4.6.0
• AWS SDK: v2.15.28 (secretsmanager, sqs, and dependencies)
• JAR Location: /mnt/efs/mirth-connect/aws-custom-jars/ (EFS mount)
• Server: EC2 instance

Problem

I need to load AWS SDK JARs programmatically without manual Administrator UI configuration (Settings → Resources → Add Resource).

What Works ✅

Manual UI configuration works perfectly:

1. Settings → Resources → Add Resource
2. Directory: /mnt/efs/mirth-connect/aws-custom-jars/
3. Check "Include All Subdirectories"
4. Save → Restart server
5. AWS SDK code executes successfully

What Doesn't Work ❌

Attempting programmatic loading in Deploy Script:

if (typeof channelMap.get('AWS_JARS_LOADED') === 'undefined') {
    try {
        var File = Packages.java.io.File;
        var jarDir = new File("/mnt/efs/mirth-connect/aws-custom-jars");
        if (jarDir.exists()) {
            var jars = jarDir.listFiles();
            for (var i = 0; i < jars.length; i++) {
                if (jars[i].getName().endsWith(".jar")) {
                    JavaScriptContext.addClasspathEntry(jars[i].getAbsolutePath());
                }
            }
            channelMap.put('AWS_JARS_LOADED', 'true');
        }
    } catch (e) {
        logger.error("Failed to load JARs: " + e.message);
    }
}

Error received:

TypeError: Cannot call property builder in object [JavaPackage software.amazon.awssdk.services.secretsmanager.SecretsManagerClient]. 
It is not a function, it is "object".

Constraint

Our deployment is fully automated via CI/CD. We deploy channels programmatically using the BridgeLink API, so manual UI steps break our automation workflow.

Questions

1. Is there a way to configure the Resources path via configuration files (e.g., wrapper.conf, mirth.properties)?
2. Can I create a custom extension to auto-load JARs on server startup?
3. Is there a programmatic API to configure Resources directories?
4. What's the recommended approach for automated BridgeLink deployments with external dependencies?

Additional Info

• Path is accessible (tested with File.exists() - returns true)
• All required dependencies are present (secretsmanager, sdk-core, auth, regions, jackson, httpclient, etc.)
• Issue is specifically about classpath loading

---

Note: I've confirmed the manual UI approach works perfectly, so this is specifically about finding the automated equivalent for CI/CD deployment purposes.

Any guidance on achieving automated JAR loading would be greatly appreciated!

Thanks in advance! 🙏
