Java Development

just to get it a little bit quicker: you can use javaloader to load applications using the command line, it's probably a lot quicker than using the BES in between.
you find it in the vmtools folder of your eclipse plugin.

Ok here are three parts for you... I reinstalled the app and pushed an email message to it.  I took a screenshot of the error log showing the events and then copied the full text of each event and pasted below.

I just finished up writing an email to RIM's dev support folks... I've never worked with them so I'm crossing my fingers that they can help.  I included a zip file with the source, workspace folder, the screenshot I posted earlier and two text files with the full text of the two event log entries... I tried to give a good breakdown of what the app should be doing vs what it is doing and some history on it.  I hope that's everything they need... 

I'm gonna keep working on it though... hopefully one of these avenues will do the trick  

I can't thank you guys enough for looking at this with me... considering this was my first post here I was worried that folks wouldn't be too friendly but you definitely proved that to be false. 

If you happen to come up with any other ideas please let me know... otherwise, again, thank you very much for your help!

Peter has you going down the right path in regards to moving code out of the listener and into your application.

Basically you are trying to do something in the listener in which the process running the listener does not have permission to do, thus triggering a ControlledAccessException.

Have you stepped through the code to see what line of code is triggering it?  That'll help you with first steps for code to move out into your own application process.  But ideally, the listener does minimal work and just fires off and update alert with data to your application, which does all of the processing.

[jgobert]

I'm trying my best to narrow it down as much as possible... my biggest issue is that I don't know if I have the chops needed to rewrite the necessary code.  I'm familiar enough with programming in general to effectively troubleshoot and with enough time and resources make corrections or updates where needed.  I'm kinda stuck with a deadline on this that totally wipes out any chance of having the time to learn enough about writing Blackberry code to make this happen.  The company bought over 100 new Bold 9900 / 9930's to refresh the fleet but without this app working we have to cancel everything within the initial 30-day window... that's closing fast on me.  My marching orders are to make it work or scrub Blackberry all together in favor of iPhone.  We've been vested in Blackberry for many years now and I have absolutely no want to have to deal with an entire platform change on top of everything else we have going on right now...  Ok... sorry for venting there... just really frustrated...

Aside from all of this I did send everything in to RIM today and paid for a dev support incident.  Based on your knowledge of how all of this works will they be able / willing to help me fix this?  I'm not 100% on what all they'll do to assist but I figured it couldn't hurt to at least pay for it and try.

Thoughts?

[simon_hain]

to move the code out of your listener you do the following:

1. in your main application, register a global event listener
http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/system/Application.html#addGlo...

2. in your mail listener, you post a global event with a GUID you set
http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/system/ApplicationManager.html... long, int, int, java.lang.Object, java.lang.Object)
(there are different methods, but this one allows you to add the message object)

3. depending on the processing needs of the code you process the message from the event received method or spawn a new thread to handle it.

[jgobert]

Thank you for the references.  I'm walking through the app step by step to make sure I see how each part comes together.  I wanted to share the following code... If I'm not mistaken it's the starting point for the application.

import java.util.*;
import net.rim.device.api.ui.*;
import net.rim.device.api.system.*;
import net.rim.device.api.util.*;
import javax.microedition.rms.*;

    Thread PrecisionMsgThread = null;
    Vector PrecisionMsgVector = new Vector();
    
    public static void main(String args[])
    {

        if ( args != null && args.length > 0 && args[0].equals("gui") )
        {
            PrecisionGUI theApp = new PrecisionGUI();
            theApp.enterEventDispatcher();
        }
        else
        {
            PrecisionCollector theThread = new PrecisionCollector();
            theThread.enterEventDispatcher();
        }
    }

    public PrecisionCollector()
    {
        try
        {
            // Register the Precision Collector with the Event Logger
            EventLogger.register(0x3401882cc7a5a956L, "PrecisionCollector", EventLogger.VIEWER_STRING);

                _DBVersionStore.setContents(_DBVersion);
                _DBVersionStore.commit();
            }
        }

            exception.printStackTrace();
        }
        
        DataStore.Initialize();

        new Timer().scheduleAtFixedRate(new ServerConnect(), 600000, 600000);
        addGlobalEventListener(this);
        IncomingMail incomingMail = new IncomingMail();
    }

    public void eventOccurred( long guid, int data0, int data1, Object object0, Object object1)
    {
        if (guid == 0x5c8e492bc9269b0cL)
        {

            EventLogger.logEvent(0x3401882cc7a5a956L, "Received Precision Message Global Event PrecisionCollector.eventOccured()".getBytes(), EventLogger.DEBUG_INFO);
            PrecisionMsgVector.addElement(EmailMsg);
            ProcessPrecisionMsg(false);
        }
    }

    public void ProcessPrecisionMsg(boolean force)
    {

        }
    }
}

class DBVersion implements Persistable
{
    public String DBVersion;
}

[peter_strange]

Looks like that too me too.  Do you have a question?

The interesting thing is that this code actually already sets up a GlobalEventListener.

The next bit of code you really want to find is the Listener - I suspect it is in the IncomingMail class. 

[jgobert]

Sorry I fell asleep at my keyboard again last night after posting that code... As I track through the code I'm trying to post here so hopefully you may see something I'm missing.  Here's the IncomingMail.java code:

import net.rim.device.api.system.*;
import net.rim.blackberry.api.mail.*;
import net.rim.blackberry.api.mail.event.*;
import net.rim.device.api.system.ApplicationManager;

public final class IncomingMail implements FolderListener
{
    IncomingMail()
    {
        try
        {
            Session.getDefaultInstance().getStore().addFolderListener(this);
            AttachmentHandlerManager.getInstance().addAttachmentHandler(new PrecisionAttachment());
        }
        catch (Exception e)
        {
            EventLogger.logEvent(0x3401882cc7a5a956L, ("Exception caught in IncomingMail Constructor: " + e.toString()).getBytes(), EventLogger.SEVERE_ERROR);
            e.printStackTrace();
        }
    }
     
    public void messagesAdded(FolderEvent event)
    {
        Message message = event.getMessage();
        Folder messageFolder = message.getFolder();
        
        System.out.println("MEssage folder: " + messageFolder.getType());
        
        if (messageFolder.getType() == Folder.INBOX && message.getSubject() != null && message.getSubject().trim().equals( "PrecisionMessage {8E730E0B-F94C-4e88-858C-20910B31C4C3}")) 
        {
            System.out.println("Received Precision Message!!!");
            // [DNT] 09/26/09 - Item#1.5
            message.setFlags(Message.Flag.OPENED);
            //message.setFlags(Message.Flag.OPENED | Message.Flag.DELETED);
            messageFolder.deleteMessage(message); 

            ApplicationManager.getApplicationManager().postGlobalEvent(0x5c8e492bc9269b0cL, 0, 0, message, null);  // ParseMessage
        }
    }

    public void messagesRemoved(FolderEvent event)
    {}
}

[jgobert]

Continuing from the previous post, the code below is for PrecisionAttachment.java which is called in the IncomingMail() try block....

import net.rim.blackberry.api.mail.*;

class PrecisionAttachment implements AttachmentHandler
{
    public String menuString()
    {
        return "Viewing Not Supported";
    }
    
    public void run(Message m, SupportedAttachmentPart p)
    { }
    
    public boolean supports(String contentType)
    {
        return (contentType.toLowerCase().indexOf("x-rimdevice-precisionmessage") == -1 ? false : true);
    }
}
