try this
JtextArea1.setDocument(new MaxSizeDocument() extends PlainDocument
{
public void insertString(int offset, String string,
AttributeSet attributes)
throws BadLocationException {
if (string == null) {
return;
} else {
int textArealength = getLength();
int newStringLength = string.length();
if (MAX_SIZE < (textArealength + newStringLength))
return; //reach limit
super.insertString(offset, string, attributes);
}
}//end method
});
