Exception Error

I am having a problem with these line of code:

TestDataManager f_TestDataManager= new TestDataManager();

Hashtable f_Parameters= new Hashtable();

f_Parameters.put("ipaddress", str[0]);

f_Parameters.put("port", "2101");

f_Parameters.put("type", "socket");

DataManager f_Manager;

f_Manager = new DataManager(f_Parameters); > this has an error

It says ConnectionException Error.

Can anyone help me with this error? Thanks...

Hi,

I have the same mistake:

The source code:

String samsys="129.169.77.181";

System.out.println("Start test samsys");

TestDataManager f_TestDataManager=new TestDataManager();

Hashtable f_Parameters=new Hashtable();

f_Parameters.put("ipaddress",samsys);

f_Parameters.put("port", "2001");

f_Parameters.put("type", "socket");

DataManager f_Manager=new DataManager(f_Parameters);

f_Manager.OpenConnection(); <-- BAD LINE

System.out.println("End test samsys");

Exception in thread "Thread-0" java.lang.NullPointerException

at com.samsys.driver.socket.SocketConnection.run(SocketConnection.java:124)

at java.lang.Thread.run(Unknown Source)

Do you know why ?

Thanks,

Aurelien
