You will need to make a special file editor which refuses to take a write lock:
public final class ROEditor extends DataEditorSupport {
private ROEditor(DataObject d) {
super(d, new E(d));
}
public ROEditor(FileObject fo) throws DataObjectNotFoundException {
this(DataObject.find(fo));
}
private static final class E extends DataEditorSupport.Env {
public E(DataObject d) {
super(d);
}
protected FileObject getFile() {
return getDataObject().getPrimaryFile();
}
protected FileLock takeLock() throws IOException {
throw new IOException("No way!");
}
}
}
Demo of usage:
JFileChooser jfc = new JFileChooser();
if (jfc.showOpenDialog(null) != JFileChooser.APPROVE_OPTION) {
return;
}
File f = jfc.getSelectedFile();
FileObject fo = FileUtil.toFileObject(f);
try {
new ROEditor(fo).open();
} catch (DataObjectNotFoundException e) {
e.printStackTrace();
}

Apache NetBeans is an effort undergoing incubation at The Apache Software Foundation (ASF).
Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.
While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
This wiki is an experiment pending Apache NetBeans Community approval.
