Hi all,
i m trying to make a GUI for tamino…and i have two classes…one class is with a frame called MyFrame and the other class has all the methods defined called Serial_Main…the main class is has this method for insertion:
I am attaching the screen-shot of my GUI and i m gettin errors after pressing INSERT BUTTON in that picture…

public static TXMLObject performInsertSerialFromFile(TXMLObjectAccessor
accessor, String filename) throws TException, FileNotFoundException {
// Instantiate an empty TXMLObject instance using the DOM object model
TXMLObject xmlObject = TXMLObject.newInstance(TDOMObjectModel.getInstance());
// Read a document out of the class path and insert it into the database
InputStream myInputStream = (new serial_tamino.MyFrame()).getClass().getResourceAsStream(filename);

//InputStream myInputStream = (new Serial_Main()).getClass().getResourceAsStream(filename);
xmlObject.readFrom(myInputStream);
//Result_Frame is just a FRAME to display the test nothin more…
Result_Frame rf = new Result_Frame();
try {

  // Invoke the insert operation and get response
TResponse response = accessor.insert(xmlObject);
printSerial(xmlObject);

}
catch (TInsertException insertException) {
rf.jLabel1.setText("\nCan't insert: ");
printSerial( xmlObject );
rf.jLabel3.setText("  Reason: " +
insertException.getAccessFailureException().
getMessageLine() + "\n");

}
return xmlObject;

}

and this procedure is called when i press an insert button after entering the name of the collection and the name of the file on my window:
public static void InsertButton_actionPerformed(ActionEvent e) {
MyFrame myFrame = new MyFrame();
try {
TXMLObject xmlObject = TXMLObject.newInstance(TDOMObjectModel.getInstance());
//xmlObject = performInsertSerialFromFile(accessor, “Movie.xml”);

   TConnection connection = TConnectionFactory.getInstance().newConnection(serial_tamino.Serial_Main.DATABASE_URI);
TXMLObjectAccessor accessor = connection.newXMLObjectAccessor(
TAccessLocation.newInstance(
(serial_tamino.Tamino_GUI.getMyFrame().ediACCESSOR.getText())),
TDOMObjectModel.getInstance());
//String Fname = myFrame.ediPARAM2.getText();
xmlObject = serial_tamino.Serial_Main.performInsertSerialFromFile(accessor,myFrame.ediPARAM2.getText());

} catch (TException taminoException) {
taminoException.printStackTrace();
}
catch (FileNotFoundException filenotfoundException) {
filenotfoundException.printStackTrace();
}
myFrame.dispose();

}

when i press the insert button after writtin the name of the file…i get the following error:
com.softwareag.common.instrumentation.contract.ViolatedPrecondition: Violated Precondition: No InputStream given.
