I have used this code for combine textFiled.PASSWORD
with TextField.NUMERIC
txtpwd.setConstraint(TextField.PASSWORD | TextField.NUMERIC);
When I run in Emulator i can type string .but i just typed NUMERIC .
I go to this link and find to combine constraints !!!
First of all. The link that you have put is a lcdui API, be carefull about it.
This is the TextField
API that you need

Ok, seeing this http://lwuit.java.net/javadocs/com/sun/lwuit/TextArea.html#setConstraint(int)
I think that you must use this line:
textField.setConstraint(TextField.NUMERIC | TextField.PASSWORD);
just the opposite.
