import java.util.*;

String mailNotificationActivityName = "";
String activityParamsName = mailNotificationActivityName + ".params";
Map params = context.get(activityParamsName);
if(params == null){
params = new HashMap();
}
String endNotificationUserMessage = context.get("endNotificationUserMessage");
String midSeparator = " ";
if(endNotificationUserMessage == null){
endNotificationUserMessage = "";
midSeparator = "";
}
String endNotificationErrorMessage = context.get("endNotificationErrorMessage");
String separator = ",";
if(endNotificationErrorMessage == null){
endNotificationErrorMessage = "Error Message :: ";
separator = "";
}
String errorMessage = "Exception occured, but no error message found";
if(exception != null){
errorMessage = exception.getMessage();
}
endNotificationErrorMessage += separator + errorMessage;
context.put("endNotificationErrorMessage", endNotificationErrorMessage);
String endNotificationMessage = endNotificationUserMessage + midSeparator + endNotificationErrorMessage;
params.put("message", endNotificationMessage);
context.put(activityParamsName, params);
