Questions about commits and orion datasource connection pooling....
Hello, I have some jsp's that are using orion's connection pooling. When a jsp page opens the db connection (oracle) through the connection pool, is it dedicated to that particular jsp page? Another jsp couldn't issue a commit or rollback and somehome impact another jsp's transactions, correct? In other words, orion simply pre-opens the connection and then hands it off to the jsp/bean/whatever for it's exclusive use. Correct? When it is done with the connection, it goes back to the pool right? Thanks, Keith
Re: How do you tell orion not to autocommit?
But I am using connection pooling I tried this and it does not seem to work... is it something I have to set with the connection pool?

Excerpt from the API docs for method java.sql.Connection.setAutoCommit(boolean autoCommit) follows setAutoCommit public void setAutoCommit(boolean autoCommit) throws SQLException Sets this connection's auto-commit mode. If a connection is in auto-commit mode, then all its SQL statements will be executed and committed as individual transactions. Otherwise, its SQL statements are grouped into transactions that are terminated by a call to either the method commit or the method rollback. By default, new connections are in auto-commit mode. The commit occurs when the statement completes or the next execute occurs, whichever comes first. In the case of statements returning a ResultSet, the statement completes when the last row of the ResultSet has been retrieved or the ResultSet has been closed. In advanced cases, a single statement may return multiple results as well as output parameter values. In these cases the commit occurs when all results and output parameter values have been retrieved. Parameters: autoCommit - true enables auto-commit; false disables auto-commit.

Re: Oracle deal
I hope this orion + oracle deal is the same as the borland jbuilder + oracle jdeveloper deal. Oracle licensed Jbuilder technology, but Borland was still free to take Jbuilder in any direction they wanted, AND oracle was free to take Jdeveloper in any direction they wanted. The end result is that Jdeveloper is way behind the curve because Oracle always buys technology for which they do not have the ability to maintain. MEANWHILE, Jbuilder is doing great and getting better and better I guess the question is Just what kinda deal did Ironflare work out with Oracle? Did Ironflare get wrapped into a straight-jacket for a few short term buck$ ?

There has GOTTA be a BETTER way !!!!
Hello, EJB's are great if you like tripling the amount of code you have to write How is everyone building their web apps with hand coded programs, or using automagic tools? It sure seems like there should be some sort of tool that you can just point at database tables, and have it build the jsp or ejb entity bean. AND shouldn't there be a tool that you can just drop the bean on an html template thus allowing visual access to the bean fields? You can't access ejb's directly from a jsp page (like a normal bean) can you? Any tools that will automagically wrap an ejb in a bean for presentation in a JSP? Am I off base here, or are ejb's a lot more work? How can people talk about how EJB's "speed development time"?!? Keith

Re: rumors
Probably not... but you know sooner or later someone is going to buy Orion... and the product price will NOT remain anywhere near $1500 OR be "free" to non-commercial projects !! I like Orion, but for projects on a budget, I think it is safer and less costly to maybe go with http://www.ejboss.org/ or http://www.evidian.com/jonas/index.htm. These are dedicated "open source" ejb servers hh if only Orion would open source. Admittedly, I don't know how the above ejb servers compare to orion.

Tieing http session to db connection in orion?!?
* some people say, it's best practice to put 1 connection into 1 user's http session and use it for all requests of that user This only works if you don't have a lot of users concurrently, say a small intranet application, that doesn't care scalibility. The reason is database connection can't be serialized for sure and connection in http session can't be replicated across your web server farm. Hence each user in a session requires to use the same machine in your web farm. This could be terrible if you intend to serve thousands of users concurrently. Secondly database licensing is an issue. Some database vendors charge you by concurrent opened connection. If your site has a thousand users concurrently, you will need to purchase a thousand licenses (That is the thing scares me most). Agreed with replier..you would NEVER want to do this. If you are not careful you can lose the connections which will ultimately crash the database and/or the web server. VERY bad design. Hello, With regards to the discussion above, and the "tieing of an http session to a single (or multiple) database connections", a lot of people downed this idea, BUT... I actually consider the "one http/db connection" to be a good way for small/medium intranet type applications to use the "transaction managment" of the database (ie oracle's "select for update", two phase commit). OTHERWISE, HOW would you handle the transaction management ?! If you use database connection pooling in an http sessionless environment, how do you handle the dirty read/write situation? What do you do if an http request fetches data for "update", but by the time the update is accomplished, the data has already changed (please don't tell me you you've coded a "check timestamp" for database rows!)? Or does everyone use optimistic locking? OR is this where the powers of EJB state + transaction managment comes in? Thanks, Keith
