LocalTransaction J2CA0024E: Method rollback, within transaction branch ID

[Jimmy Kennedy]

Hi,
I have a written an MDB which listens on WebSphere MQ Queue Connection Factory .In ejb-jar.xml ,I set trans-attribute for onMessage method to be Not Supported.
In MDB ,onMessage() I have written this code
try{
if(msg instanceof TextMessage){
String msgText = ((TextMessage)msg).getText();
// this code basically reads input text and in turn make a database call and get some data.
EQLParser objparser = EQLParser.getInstance();
boolean flag = objparser.log(msgText);
if(!flag){
log.info("Due to certain errors ,msg failed to log ");
}
}}catch(Exception e){
System.out.println("DEBUG MDB Exception ::::"+e.getMessage());
}

It works fine ,as the requirment but after onMessage method ,Container throws an exception as shown below:
