RE: idea=$395.00USD was: RE: Java IDE?
after enjoying watching this debate for the last while I decided to check out what all the fuss was about so I downloaded the IDEA software. Now I will be honest, JDeveloper has been my tool of choice for a long time I have tried others (ie. JBuilder and I know JDeveloper is licensed from it but I really dont like it, also used the likes of visual cafe I hated that one and so on and so on) back to the plot, I haven't been playing with it for too long but I dont see what all the shouting is about so maybe someone could give me their view who has used both IDEA and JDeveloper 9i extensively cause I am not convinced at all that it is better that JDev9i -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Joseph Ottinger Sent: 24 March 2002 12:50 To: Orion-Interest Subject: Re: idea=$395.00USD was: RE: Java IDE?

Yes, I can use a tool like 'vi' to build the better stuff, but I can't use Idea to do better than Idea if you see what I mean. Like a dinosaur Idea has made its evolutionary commitment, as have the other dinosaurs of similar ilke. It sounds a lot better than JBuilder though for what it does ... it simply doesn't sound better than my tools ... ;) Spoken (or typed) like a man who's used JBuilder and assumed IDEA's just like it. IDEA doesn't write code for you unless you tell it to. And when you tell it to, it writes the code you told it to. It doesn't generate GUIs that suck. In fact, it doesn't generate GUIs at all. It's an editor. A java editor. Not a crappy IDE like Netbeans or JBuilder. Not an editor with Java features, like VSE or Emacs (both of which I've more than a passing familiarity with.) It's an editor whose designers said, What do Java people need to do? and the editor enables that. It doesn't require the developer to do things. It enables the developer, and gets out of the way. Sorry for the caustic tone, but it sounds like you're rendering judgement without a clue, based on price and misconceptions. regards goffredo Um, dude... you're using a commercial product. Why? Typically, because the value you get out of licensing it gives you a good return on your investment. I *could* use Tomcat instead of Orion... but Tomcat sucks. It's free, but it sucks. If it didn't suck, the return on the investment of time would be worthwhile. I use Orion. (Do the math.) Editors work the same way. I *could* use vi, or emacs (and I used to use vi and emacs), but I found that IDEA boosted my productivity (the return) so much that I was able to justify the cost (the investment) easily and well. And that's after wasting my time with JBuilder, Forte, Kawa, JEdit, Netbeans (which is better than Forte, despite Forte being based on Netbeans, joe, vi, emacs, and Eclipse (and I'm sure I'm leaving some out in this list). If you're going to wave the It's not free flag, run back to Tomcat and Apache where you belong. JBuilder was a waste of time after using it for years, and waking up to the fact that I only used it to package classes anyway.

RE: Where is my stderr output?
if I understand you correctly what you need to do is check in your application.xml for the log file path=something.log / /log This will lead you to where your log file is located and if you haven't set it then simply set it by default I think most of the log files are kept in the ORION HOME\log folder John Creaner Software Development, e-Spatial Solutions, Ireland.

RE: java.lang.OutOfMemoryError
Just wondering but are you allocating any of that GB to orion or are you letting the box allocate the memory itself? I think that the box gives a default amount of memory to java and so that could be the reason you are running out of memory You can allocate by giving param setting on the startup script. ie your start up could look something like java -jar -Xms250M -Xmx500M orion.jar the -Xms is the min amount of memory the machine must allocate. the -Xmx is the max amount of memory the machine can take.

RE: Looking up session beans between apps
I suppose if the 2 servers are on the same machine then you could possibly put the beans into their own directory and share that directory between the 2 servers but then you have to think do the beans have to share instances of the beans? Does 1 server initialize 1 bean and then can the other server reference it? I suppose you could work around that by saving the bean instance to disk but that might be a lot of work (referencing it, sharing it, etc;) I don't really know a good secure answer to that, but I would definitely like too -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: 07 March 2002 08:20 To: Orion-Interest Subject: Re: Looking up session beans between apps Hi, try to put the remote and home interface of your bean in the app server classpath ( server.xml ), i think it will solve your problem if Bean A and Bean B are on the same server. Does anybody know how to solve this problem if bean A and bean B are on different server ?? Thanks. Rémy. Gday all, I am currently working on porting an application from jboss to orion (don't ask!) and am having problems looking up session beans between apps. What i am trying to do is lookup sessionbeanA (in app A) from sessionbeanB (from app B). (Note that sessionbeanA and sessionbeanB are different bean classes). I am getting a class cast ecxception. This is how i am doing it So in sessionbeanB I create a context using the following properties.. props.put( Context.INITIAL_CONTEXT_FACTORY, com.evermind.server.ApplicationClientInitialContextFactory ); props.put( Context.PROVIDER_URL, ormi://localhost/sso-wa ); props.put( Context.SECURITY_PRINCIPAL, guest ); props.put( Context.SECURITY_CREDENTIALS, ); .. and can successfully locate an instance of sessionbeanA. Then i attempt to narrow it. The class i want to narrow to is SSOManagerHome. The class of the object being narrowed is SSOManagerHome_StatelessSessionHomeWrapper27 It looks OK to me, but the narrow gives and exception. java.lang.ClassCastException at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(Unknown Source) at javax.rmi.PortableRemoteObject.narrow(Unknown Source) .. I have found some similar problems.. http://www.elephantwalker.com/searchresult?id=277 http://www.mail-archive.com/orion-interest@orionserver.com/msg17468.html But no solutions :( So where to from here??? Is there a solution? Will the remote access doco http://www.orionserver.com/docs/remote-access/remote-access.xml be of any help as i am going session bean to session bean? (as opposed to web component to session bean). Thanks and Regards Ryan
RE: JDBC connection leak
Hi,
Not sure if this is what your looking for but you should really close all
associations to the connection
cause I think that the way CMT works with orion is that the close method
merely returns it to the pool
so you should do the following before you close:
stmt = conn.prepareStatement(sqlStatement);
stmt.setString(1, websiteid);
ResultSet rs = stmt.executeQuery();
rs.next();
siteEndDate = rs.getTimestamp(1);
siteBeginDate = rs.getTimestamp(2);
// Here
rs.close ();
stmt.close ();
conn.close();
This means that the connection is now free for the CMT to use again (I THINK
;)

Subject: JDBC connection leak
Hello!
I call the following code in a Message Driven Bean in Orion 1.5.2. After the
conn.close() all entity beans I created in some code before are destroyed.
The database is empty. The sql statement gets the right result but after the
close everything is lost. No error, nothing. Without the close statement
Orion says that there is a leaked connection and that I have to close it:
==
OrionCMTConnection not closed, check your code!
LogicalDriverManagerXAConnection not closed, check your code!
(Use -Djdbc.connection.debug=true to find out where the leaked connection
was created)

Can anybody help me?
Thanks in advance.

The code:
PreparedStatement stmt = null;
java.sql.Timestamp siteEndDate;
java.sql.Timestamp siteBeginDate;
try {
javax.sql.DataSource ds =
(javax.sql.DataSource)jndiContext.lookup(jdbc/sapdbDS);
Connection conn = ds.getConnection();
//Connection conn =

RE: Problems configurating classpath
All, I have a small question, I am currently having a problem with orion. The problem is that it doesn't seem to be taking advantage of the machine that it situated on. The question is how or is it possible to configure orion to take advantage of the machine that it is placed on top of ? Thanks

hi, I was wondering if anyone out there has any solid information on clustering orion server thanks
