Java & Domino: what are my options here?

Hi All ::

I’ve done some extensive searching on this and other sites relative to the Java / Domino topic. I’m struggling to understand what options I have for my scenario.

I need to write a little utility (as an eclipse plug-in) that accesses a Domino database on a remote server. I’ve found lots of good examples for the Java API (NSCO.jar / Notes.jar); however, I have no control over the Domino servers and since my app’s are dying with “Could not get IOR from Domino Server” (after lots of debugging, changing ports, protocols, etc) I believe that DIIOP is simply not running on the server. So…

  • Is DIIOP required in order to use the Java API to access a remote Domino Server?

  • Are there any other methods I can try?

I found a redbook that talks about LCJava and a JDBC for Domino… I cannot find anything more on lcjava other than a post somewhere that hinted to it being deprecated… and no signs of JDBC drivers… I downloaded LSX toolkit, but that looks overly complex for what I want…

Am I missing something obvious? Thanks in advance.

You can use “native” access to databases from Java without DIIOP. To do this you need to have a Notes client installed on the computer and a valid ID-file. Port 1532 must be open on network in order to connect to Domino server. Instead of NSCO.jar you use Notes.jar and make sure all paths/classpaths can be found by your Java program. I did not try this solution in large-scale applications.

You can also access Domino server by calling database’s URL and parsing the answer (HTML or XML), as the other poster suggested.

Thanks everyone for the replies… Andrei - I like the idea of using the native methods… can you point me to a quick sample-code page that shows how to establish a session, get DB, etc? is it the same just using local methods?

For example::

s = NotesFactory.createSession();

db = s.getDatabase(ServerName, DBName);

View view = db.getView(ViewName);

What about threads? I recall reading that local access requires threads, is that the same here?

thanks again for the help…

Subject: got it!

Sorry about that… but yes, if you use the “local” method it will work (as Andrei suggested) - for others looking to try this, here a snippet that i used::

// make a class that extendes NotesThread

public class AccessNotes extends NotesThread …

public static void main(String args) {

    try {

        AccessNotes an = new AccessNotes();

        an.start();

…

public void runNotes() {

try   {

s = NotesFactory.createSession();

db = s.getDatabase(ServerName, DBName);

View view = db.getView(ViewName);

// other code as needed…

hope this helps someone… thanks to everyone else for your help!

Yes.

You can read stuff via http URLs like ?readviewentries etc. You can even post stuff if you pretend to be a browser user. If you want to use the CORBA API then turn on the CORBA server (DIIOP)
