I wrote a small java code which updates a clob data, when i run the above program , it throws Abstractmethoderror at runtime in rs.getClob(1);
Does anyone know what it is?

it means that the oracle driver you are using has not implemented the method yet ( doesn't exist ). For information on writing/reading clob's from Oracle see this sample code

I am having a similar problem as to how to get a string into a clob for my oracle database. i can get the clob out ok using..
public String getModel() throws RemoteException {
String returnString = null ;
String line = null ;
Clob clob = (Clob)model ;
BufferedReader clobData = new BufferedReader(clob.getCharacterStream( ));
while((line = clobData.readLine( )) != null){
returnString += line ;
catch( Exception e ){
e.printStackTrace() ;
throw new RemoteException( e.getMessage() ) ;
return returnString ;
it is getting the string into the clob that is the problem. I am using JBoss with CMP for the class and oracle but i would like the app to be database independant.
Having looked at the solution i am aware that it is using native oracle code. Is there a way around this to use non vendor specific code?
Thanks for any help in advance.
I agree. Here's the link:
