Hi All,
Continuation to my earlies mail for which [EMAIL PROTECTED] has
replied, here is the complete scenario, where this problem is coming.
Please find the getData() implementation in the Entity Bean
public SubNetData getData() throws RemoteException {
System.out.println("Inside the getData of SubNetworkBean ");
m_trace.print("SubNetworkIntfBean :getData() called ");
SubNetData data = new SubNetData();
data.m_name = m_name;
data.m_domainName = m_domainName;
data.m_type = m_type;
data.m_discvStatus = m_discvStatus;
data.m_discvDateTime = m_discvDateTime;
data.m_neListString = m_neListString;
data.m_configuration = m_configuration;
data.m_neVector = m_neVector;
return data;
}
The SubNetData which its referring is a Serializable class which I already
mentioned.
Please find the content of the Server.log file related to this error.
