From the Java Class Library book. Excuse any typos. The call you want is the setEditable() one below.

import java.awt.*;
class Main extends Frame {
TextArea ta = new TextArea();
Checkbox cb = new Checkbox("Editable", null, true );

Main() {
super( "setEditable example" );
add( "Center", ta );
add( "South", cb );
pack();
show();
}

public boolean action(Event evt, Object ob ){
  if ( evt.target == cb ) {
    ta.setEditable( cb.getState() );
  }
  return true;
}

static public void main(String[] args) {
  new Main();
}
}

Simply invoke the textArea's setEditable method to be false.

TextField mytext = new TextField();
mytext.setEditable(false);

If U want to prevent someone to change your TextArea context
use SetEditable(false) method, this way.
-----
//your previously defined TextArea
TextArea ta=new TextArea();
ta.setEditable(false);
