Hi ,

I am new to Customization of elements using java code and not at all great at java
I have a custom element which is sending email and capturing any error but just adding it to the log .
I want to capture this error as element data so that I can playback an error message to caller and ask him to try again.
Can you please guide me where and what to put the code for setting the error captured as element data.

Below is my java code


import com.audium.server.AudiumException;
import com.audium.server.session.ActionElementData;
import com.audium.server.voiceElement.*;
import com.audium.server.xml.ActionElementConfig;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.*;
import javax.mail.internet.*;

public class SendMail extends ActionElementBase
    implements ElementInterface
{

    public SendMail()
    {
    }

    public String getElementName()
    {
        return "SendMail";
    }

    public String getDisplayFolderName()
    {
        return "Custom Elements";
    }

    public String getDescription()
    {
        return "This action element Sends EMail";
    }

    public Setting[] getSettings()
        throws ElementException
    {
        Setting settingArray[] = new Setting[5];
        settingArray[0] = new Setting("To", "To", "[email protected]", true, true, true, 3);
        settingArray[1] = new Setting("Subject", "Subject", "Subject", true, true, true, 3);
        settingArray[2] = new Setting("Body", "Body", "Body", true, true, true, 3);
        settingArray[3] = new Setting("Attachment", "Attachment", "Attachment", false, true, true, 3);
        settingArray[4] = new Setting("Filename", "Filename", "Filename", false, true, true, 3);
        return settingArray;
    }

    public ExitState[] getExitStates()
        throws ElementException
    {
        ExitState exitStateArray[] = new ExitState[1];
        exitStateArray[0] = new ExitState("done", "done", "done");
        return exitStateArray;
    }

There are different ways to do it.  In your catch error block you can set something like:
catch(Exception e)
{
actionData.addToLog("Failed to Send Email", "");
actionData.addToLog("Error", e.toString());
//Define this string before
returnStatus=”error”;
}
 actionData.setElementData("returnStatus",returnStatus);
 
Check this returnStatus after the action element and play to the caller what you want.
Other  way you can do is to implement this as a decision element and define the exit state for error, success etc and branch out and play the appropriate message for error to the caller.
