I am using OpenJMS for some application. I have server running on one machine
and form some other 2 machines I try to write messages on the queues on the
server. Before writing to the queue, I first create the queue dynamically
and then write to it. I have the same classes on all the machines. But from
one of the machines , when I am tying to create an admin object , I get an
error like  :
JMSException Failed to lookup OpenJMS administration server at URL:
tcp://10.74.64.157:3035

Ans surprisingly this error comes only once.. I mean I am creating this
admin object at several places in the code.. but it throws this exception
only once. I am also attaching the code that I have written to add
destination to the server. 

public String addDestination(String url,String name, int retryCount)
	{
		//Queuename = url.replace(".","/");
		this.Queuename = name.replace(".", "/");
		url="tcp//" + url + ":3035";
		
		System.out.println("JMSServerHandler :  Queuename = " + Queuename);
		System.out.println("JMSServerHandler :  url = " + url);
		
		try{
		admin = AdminConnectionFactory.create(url, "admin",	"openjms");
				Boolean isQueue = Boolean.TRUE;
		if (!admin.destinationExists(Queuename)) {
			if (!admin.addDestination(Queuename, isQueue)) {
				mLog.error("Failed to create queue " + Queuename);
				System.out.println("Failed to create queue "
						+ Queuename);
			} else {
				System.out.println("A fresh Queue Created " + Queuename);
			}
		}
		else{
			System.out.println("Queue already Exists");
		}
				
	}
		catch (MalformedURLException e) {
			mLog.error("JMSServerHandler:  MALFormed URL Exception"
					+ e.getMessage());
			System.out
					.println("JMSServerHandler :  MALFormed URL Exception"
							+ e.getMessage());
			return null;
		} catch (JMSException e) {
			mLog.error("JMSServerHandler: JMSException "
					+ e.getMessage());
			System.out.println("Could not add the JMS Destination - JMSServerHandler: 
JMSException "
					+ e.getMessage()+ "  " + e.getErrorCode()+ "  " +
e.getLocalizedMessage());
			
			
			return null;
		}finally{admin.close();}
		
		return Queuename;
	
	}




I would be really thankful if you could suggest me some reason as in, why I
might be getting this error.
