problem in reading message for IBM MQ series using IBM MQ classes

[ramjcp kris]

Hi All

I am new to this MQ Series. i have a requirement in which we are using IBM MQ classes
following is the code used for reading message from queue

 MQQueueManager qMgr = null;
MQQueue queue = null;
 
env.put(MQC.HOST_NAME_PROPERTY,"HostName" );
env.put(MQC.PORT_PROPERTY, "portNumber");
 
env.put(MQC.CHANNEL_PROPERTY, "Channel");
qMgr = new MQQueueManager("QmanagerName", env);
 
int openOptions = MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_INQUIRE;
queue = qMgr.accessQueue("QueueName", openOptions,null, null, null);
 

MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.options = MQC.MQGMO_SYNCPOINT | MQC.MQGMO_WAIT;
MQMessage myMessage = new MQMessage();
myMessage.characterSet = 1208;
   

reading from queue using following code

  String msgInString = null;
msgInString=myMessage.readLine();  

now msgInstring contains whole message.

now this string consists of japanese characters.
my requirement is i need to divide this string ( entire message) into multiple records say each of 180 bytes
and write these records into text file.

can any one suggest me , how can i split the entire message which is of string format
into multiple of 180 bytes (each record) and writing these records into text file.
more over this received message consits of japanese characters.
without loosing this encoding i need to achieve.
