Domino Java代理执行报错求助：触发方式为菜单选中事件

Hey there, let's work through this Java agent issue you're facing. Since you noted the agent has a target of None and triggers via the "Action Menu Selected" event, here are targeted steps to diagnose and fix the problem, based on the imports you shared:

1. Fix Missing Third-Party Dependencies #

You’re using org.json.* and com.mashape.unirest.*—these aren’t included with Domino by default, so missing JARs are a common culprit:

• In Domino Designer, right-click your agent > Build Path > Add External Archives to include the JSON and Unirest JARs directly in the agent.
• If the agent runs on a server, place these JARs in the server’s jvm/lib/ext folder (or your local Notes client’s equivalent directory for client-side runs).
• Stick to versions compatible with Domino’s JRE (most recent Domino versions use Java 8)—Unirest has had breaking updates, so avoid the latest versions if they require newer Java.

2. Validate OpenNTF Domino API Setup #

Since you’re importing org.openntf.domino.*, make sure:

• The OpenNTF Domino API JAR is installed on your server/client and referenced in your agent’s build path.
• Your code uses the API correctly: prefer Factory.getSession() over the standard NotesSession to avoid context conflicts, especially with a None target agent.

3. Adjust for the "None" Target Context #

Agents with a target of None don’t have a default document/database context, so:

• Explicitly fetch resources instead of relying on implicit references. For example, use Factory.getSession().getCurrentDatabase() to get the current database—don’t assume it’s available automatically.
• Add debug logs like System.out.println("Reached HTTP call step") at key code points. Check the Domino console or agent log to pinpoint exactly where the error occurs.

4. Resolve Security & Permission Issues #

Unirest makes outbound HTTP calls, which can hit Domino’s security restrictions:

• If running on a server, confirm the server’s security policy allows outbound requests to your target URL.
• Check the agent’s "Run as" settings (agent properties > Security tab). If it’s set to "Run as web user" or a restricted ID, switch to "Run as agent signer" (if allowed) to grant enough permissions for external calls.

5. Dig Into the Exact Error Stack Trace #

The most critical step is getting the full error details:

• Look for the stack trace in the Domino console or the agent’s log file (server data directory or local Notes logs). It will tell you if it’s a ClassNotFoundException (missing JAR), NullPointerException (uninitialized object), or an HTTP error from Unirest.
• Even without sharing the exact message, the above steps cover most common issues for this agent setup.
