Has anyone successfully used JCIFS library in a Java agent to access files in a shared folder on a Windows file server? The file server is actually a Linux server, but it is running Samba to create a Windows file share and a scheduled agent will put files up on it.

Here is the code I'm using as a proof of concept:

import lotus.domino.*;
import jcifs.smb.NtlmPasswordAuthentication;
import jcifs.smb.SmbFile;
import jcifs.smb.SmbFileInputStream;
import jcifs.smb.SmbFileOutputStream;

public class JavaAgent extends AgentBase
{
    private static final String USERNAME = "username";  //obviously changed
    private static final String PASSWORD = "password";
    private static final String SERVER = "fileservername";

    public void NotesMain()
    {

        try
        {
            Session session = getSession();
            AgentContext agentContext = session.getAgentContext();

            // (Your code goes here)
            SmbFile smbDir = connect("smb://" + SERVER + "/secured", USERNAME, PASSWORD);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
    public static SmbFile connect(String smbServer, String userName, String pwd) throws Exception
    {  
        NtlmPasswordAuthentication ntml = new NtlmPasswordAuthentication("", userName, pwd);  
        SmbFile client = new SmbFile(smbServer, ntml);  

        return client;  
    }  
}

 

It seems to be a permission problem on the Domino side. I have the agent running level "3. Allow restricted operations with full administration rights".

Here is the error I'm getting:

java.security.AccessControlException: Access denied (java.net.NetPermission specifyStreamHandler)

From some of my searching about security errors when using Java agents, I saw some notes talking about modifying a "java.policy" file. Is this what needs to be done to get this to work?
