Changing ClassDescriptor in managed environment

[Stephen Ting]

I have problem in changing ClassDescriptor in managed
environment(Jboss-container managed transaction). Whenever I add the
following code exceptions thrown. 

Another question, what's the difference between using the following 2
statements, if I used put method, exception is not thrown but the
ClassDescriptor changes doesn't take place. 

1. broker.getDescriptorRepository().put(LogReceivingItem.class,cd);
2. broker.getDescriptorRepository().setClassDescriptor(newCd); 


FieldDescriptor updateField =
broker.getClassDescriptor(LogReceivingItem.class).
getFieldDescriptorByName("status"); 
FieldDescriptor pkField =
broker.getClassDescriptor(LogReceivingItem.class).getPrimaryKey(); 
ClassDescriptor origCd = broker.getDescriptorRepository().
getDescriptorFor(LogReceivingItem.class);
ClassDescriptor newCd = new
ClassDescriptor(broker.getDescriptorRepository()); 
newCd.setTableName("LOG_RECEIVING_ITEM");
newCd.addFieldDescriptor(pkField);
newCd.addFieldDescriptor(updateField); 
broker.getDescriptorRepository().setClassDescriptor(newCd); 

Iterator iterate3 = issueItem.iterator(); 
while(iterate3.hasNext()){ 
        LogReceivingItem receivingItem =
(LogReceivingItem)iterate3.next(); 
        tx.lock(receivingItem,Transaction.WRITE);
        receivingItem.setStatus(ILog.LOG_ISSUED); 
} 
broker.getDescriptorRepository().setClassDescriptor(origCd);

Stephen
